Running a 26.2 mile marathon is on many bucket lists. Rooted in Greek history, the distance attained legendary status when Phidippides ran from Marathon to Athens to announce a victory. The word itself is a ubiquitous metaphor for any sustained effort. But for some people, 26.2 miles is not enough. In fact, it’s just the beginning.

Ultrarunning begins where the marathon ends. It’s defined as any distance greater than 26.2 miles.

But did you know that Phidippides was also the first known ultrarunner? He died suddenly after running more than 175 miles in two days (culminating in the marathon). That’s right, ultrarunning is so badass that the guy who invented it died doing it.

Phidippides’ death in 490 B.C. hasn’t discouraged the runners who’ve followed. The training is mind numbing. The trails rocky, remote, and arduous. There is little prize money or glory. “Some people think I’m crazy to run 100 mile races,” says ultra coach Keira Henninger, “I think I’m the luckiest person on the planet to experience a physical and emotional journey in the most beautiful landscapes in the world.”

So how hard is it to run 100 miles? And what happens to your body when you do?

Your body on Ultras

Running an ultra is not for the faint of heart. Raceday risks include:

• Hallucinations
• Blurred vision
• Insect bites or stings
• Cuts and bruises
• Heart problems
• Respiratory ailments
• Dehydration
• Electrolyte imbalance
• Hyponatremia
• Hypothermia
• Gastrointestinal problems.
• Muscle cramps
• Stress fractures
• Blisters

Each organ of the body is impacted by the effort.

The Heart

Running an ultra stresses a runner’s heart during and after the race. Most finishers exhibit elevated Troponin I, which can indicate heart damage. There is continuing debate whether it causes lasting damage. Sustained exertion impacts each side of the heart differently. The left can become stronger through running. The right side, however, can dilate and weaken. For some vulnerable runners, this dilation and related scar tissue can cause cardiac arrest. There is a slightly elevated post-race risk of atrial fibrillation, an irregular heartbeat and temporary cardiac dysfunction.

In some regard, ultra are less risky than marathons. Marathoners spend the majority of their race at 75 to 85 percent of their maximum heart rate. Ultrarunners stay in the 50 to 65 percent range. This lower intensity lessens the risk of race day cardiac events.

Outside magazine calls the heart a Runner’s Ticking Time Bomb, reporting that one in 200,000 runners will experience cardiac arrest, and one in 50,000 will experience a heart attack from coronary artery disease during a marathon. For this reason, doctors recommend more pre-race screening.especially for ultra which tend to be held in remote areas away from trauma centers or critical care centers.

Heart attacks can mimic normal race exertion. Sweating, difficulty breathing, chest pain-all can be both normal parts of extreme running. Or signs of a heart attack. Gordon Tomaselli, a cardiologist at the Johns Hopkins Outpatient Center, explained an athlete’s ability to run right through all the warning signs. “”you can be totally asymptomatic, and your first symptom is sudden death.” It’s important for runners to be cardio-cleared before undertaking ultras.

Phidippides cardiomyopathy

The sustained cardiac effort of an ultra can tax the heart with volume overload. This syndrome is named for the speculative cause of death of the first marathoner, Phidippides.

Limbs and Joints

Ultrarunners average 5000 strikes of the foot to the ground per hour.. This has a colossal cumulative effect on the joints, especially the feet and knees. Stress fractures are common. Toenails often turn black and fall off. Joint pain may arise during the race and continue after it’s finish.

Muscles

Runners use glucose for energy. Lactate is a byproduct of the breakdown process, but can also be converted back into energy. At some point your body can no longer convert the lactate. Acidity in the muscles builds up. This is called the lactate threshold.

Arm fatigue can leave you unable to hold your water bottle.

Foot-eye coordination can help avoid stumbles and falls as muscles tire.

Central fatigue can strike, along with exercise-associated collapse syndrome, where a runner’s muscles simply stop working. Training before the race, and pacing and rest during the rest, is key to performance, recovery, and injury prevention.

Although the intense driven runners who seek out ultras are not naturally inclined to hold back or pause for a spell, resting smart can mean the difference between finishing the race or dropping out. Otherwise runners will ‘bonk’ or hot a wall, a full depletion of energy described as a “unique and instant kind of despair”. If your heart rate is too fast the heart is straining to maintain blood volume and deliver oxygen to your muscles. A slowing heart rate can signal fatigue as the pace slows and the body demands less oxygen. Appropriate pacing, hydration, and fueling promote a steady heart rate.

Mind over Matter

Training and race day efforts are overwhelmingly physical. But focus and mental toughness also play a significant role.

Tracy Gariepy ran 300 miles from North Carolina to Georgia to raise money for Girls on the Run. “The human body is capable of FAR more than you give it credit for,” says Tracy, “your mind will attempt to pull you out of the race long before your body really needs to. But you walk (or crawl) away from an ultra a different person than you were when you toed the starting line.”

Science has even quantified how much mental toughness counts. Measuring traits such as confidence, the sense of being in control, concentration, determination, and acceptance of responsibility, researchers found that mental fortitude accounted for 14% of racing success. The ability to set goals and refocus efforts significantly improved race results.

Salt Levels

Our bodies naturally balance sodium and water. But the exertion of ultras can challenge this survival mechanism and our electrolyte balance.

Runners who finish 100 miles have temporarily abnormal (elevated) kidney values as they flush the remnants of broken muscles from their blood . Cola colored urine is a dangerous sign of possible rhabdomyolysis which can lead to organ failure. Weight gain during a race is another signal that runners are not sufficiently excreting water and salt.

Runners in hot climates are 10 times as likely to have a brain centered heat stroke than a cardiac event. Hydration, cooling, and salt intake can prevent a life threatening event.

Caloric Intake and Digestion

Unlike shorter distances where runners can get by on the odd post-race banana, ultra runners need as much as 80g of carbs an hour to maintain their energy. Runners are burning 400 -600 calories an hour. They need supplemental calories to replace the glycogen depletion. Ultra aid stations can resemble picnics with sandwiches, pasta, burgers, candy, even beer. to eat during the race.

This food poses a special problem for the ultra runner. But running triggers the parasympathetic response. Adrenaline courses through the body. Blood moves away from the internal organs to fuel and oxygenate the muscles. This dulls appetite and slows digestion. 60 percent of runners will get nauseous, perhaps from lactate build up as they reach the lactate threshold.

“You must keep eating,” says ultrarunning expert Kieran Alger, “It’s a horrific notion and a cruel trick but the thing you desire least is the thing that’s going to cure you.” As cortisol levels rise the body targets fat stores to prevent muscle fatigue.

Sleep

Sleep deprivation. It’s possible the hallucinations experienced by some ultrarunner are the body’s attempt to make up for lost sleep. Dean Karnazes author of “The Road to Sparta” has run for three days and three nights straight. He said eventually he ends up sleep running: “falling asleep while in motion, and I just will myself to keep going.”

Environmental Risks

Remote settings complicate emergency medical treatment. Race doctors need to be ready for everything from trauma, acute coronary syndrome, heat stroke, hypothermia, hypoglycemia, exercise-associated hyponatremic encephalopathy, severe dehydration, altitude illness, envenomation, anaphylaxis, and bronchospasm.

Besides the physical and mental risks, ultra runners face environmental dangers on the trail: from lightning, falls and animal attacks. This is not hypothetical. In June 2016 a trail runner was killed by a bear in Alaska.

In 2014 Adam Campbell finished third in the Hardrock 100 ultra distance trail run, after being struck by lightning at mile 60.

An Old Man’s Game?

UltraRunning Magazine reports two thirds of the runners are men, and more than half are over 40. Unlike shorter distances where youth and speed are an advantage, ultras rewards patience and conservation of resources When it comes to pacing and planning, experience counts.

Born to Run?

Author Chris McDougall says humans are born to run. But he acknowledges, “Usain Bolt can get his ass kicked by a squirrel. That would be an Olympic event: turn a squirrel loose, whoever catches it gets a gold medal.” What’s remarkable is that women become more competitive as distances get longer, and older man can complete ultras at speeds comparable to their youth.

Training

Racing an ultra requires obsessive focus. MMA Fighter Jayquan Jackson stresses preparation: “80% of your muscles are made in the kitchen,“ he says. “Even if you are in great shape, don’t expect to just wake up one day and be a marathon runner. There will be many days where you don’t feel like running, many days where you don’t want to get up, and many days where the idea of going outside makes you want to shove cake in your face until you pass out. Consistent boosts of motivation is key.”

When it comes to training, a focus on time not miles can ensure a runner is ready but not overtrained.

“Burning around 14,000 calories in a day is a challenge,” says Carson Robertson an ultra runner and chiropractor, “and doing it without serious injury takes training.” Robertson, who teaches Anatomy and Physiology adds, “To me 100 miles is like motorcycles. You either get it or you don’t.”

Shawn M Talbott, PhD has completed more than a dozen ultra marathons. “I like ultras more for the mental challenge than for the physical challenge, “ says Talbott, a nutritional biochemist, “they are almost certainly not “good for you” in terms of health effects – but they are very good for the “soul” and for finding your mental limits.”

Other Races

An ultra race is any distance over a marathon’s 26.2 miles. There are many varieties.

The Longest Race

The Self-Transcendence 3100 mile race is the world’s longest certified footrace.Entrants run from 6am to midnight for 52 days. They must average 60 miles a day.

The Secret Race

Barkley Marathons, the world’s toughest and most secretive trail race was featured in a documentary. “The only prize,” says the The New York Times, “is that after 100 miles, they get to stop.” Also known as The Race that Eats its Young, the entry procedure is an off-putting complex mystery, many runners get lost, and less than 2% finish.

Triumph of the Human Spirit

That an ordinary person can physically train to run 100 miles for three days and nights is amazing. The fact that folk continue to seek these races out, and finish them, is a testimony to human will and aspiration.

Blisters? Heatstroke? Bear Attacks? Endurance running is not for everyone. It offers an exquisite intersection of mental challenge and physical prowess. Those who can do it, often choose to do it again.

“You could experience 10 hours of rain, 12 hours of sun, a headwind for 50 miles,” says running coach Kyle Kranz. “It’s cliche, but upon completion of your first ultra marathon, you sort of get a sense that you’re pretty fricken awesome and capable of more than you thought.”

And that’s exactly why, hard as these ultra races are, folk will continue to run them.

Whether you’re getting only five hours of shut-eye or snoozing through your morning alarm, we all need a healthy amount of high-quality sleep to remain productive, attentive, and ready to conquer the day.

Yet, many fail to realize that a clear distinction exists between quality sleep and sleep that does little for your overall health. While getting eight hours of sleep per night may sound healthy upon first glance, it’s the quality of your sleep, not just the quantity, that truly matters. For this reason, sleep analysis has become an important benchmark that we can use to monitor our sleep and understand our overall health.

“The importance of tracking your sleep and sleep analysis rests on what an individual is trying to figure out,” says Dr. Christopher Winter, owner of Charlottesville Neurology and Sleep Medicine and CNSM Consulting. “It’s important for us all to track our sleep, but it’s more important to think of why we’re tracking our sleep in the first place.”

So what exactly is sleep analysis? In short, sleep analysis is the process of monitoring your sleep patterns over time, with help from sleep trackers and fitness wearables, in an effort to ensure you’re receiving quality sleep. And if you’re not experiencing sufficient sleep, then the sleep data you collect can help you make informed decisions that will give you a chance to get better sleep.

Read on to learn more about the basics of sleep, what factors influence the quality of your sleep, and what you can do to track and analyze your sleepover time.

The Various Stages of Sleep

There are four primary stages of sleep to be aware of. We refer to these stages of sleep collectively as the sleep cycle.

The first stage of sleep is the lightest stage. It’s known for producing non-rapid eye movement sleep, or Non-REM sleep. During this light sleep stage, your eyes move slowly beneath your eyelids and you can be easily disturbed by your environment — noises or movement can wake you rather easily. Your muscles will slowly relax, your body temperature will drop, and your brain will transition into a period of rest as internal systems prepare for a more peaceful, deeper sleep in stage two.

The second stage of sleep occurs when your body begins to produce rapid eye movements (REM). This stage of sleep is also known for producing sleep spindles, which are short bursts of brain activity meant to protect your brain from waking during deep sleep. Unlike stage one of the sleep cycle, you can’t be woken as easily during this REM stage of sleep.

The third stage of sleep is known as deep NREM sleep. During this stage, your brain will produce slow-waves as your body and mind work to heal themselves after a full day of activity. Abruptly waking up during this stage of sleep is uncommon, and sleeping events such as sleepwalking and sleep talking occur during this stage.

The fourth and final stage of sleep is known as REM sleep. This is where vivid dreams take place because your brain waves are more active than they are in stages two and three. Your eyes will again move back and forth, but only until your body starts the cycle over again. You run an increased risk of feeling groggy or suffering from sleep inertia the following day if you’re woken during REM sleep.

One sleep cycle will last anywhere from 100-120 minutes, and you’ll transition through four or five cycles per night.

Ensuring you reach each of the different stages of the sleep cycle is important, but there’s more to this story than meets the eye. “How we feel about our sleep can impact our daily performance more than how we actually slept,” notes Winter. “Belief about sleep really influences the way we report it to other people and the way we perform that day.” For this reason, it’s crucial that we not only transition through the four stages of sleep but that we believe in our ability to get beneficial sleep too.

What Factors Influence Your Sleep?

We collectively refer to the many sleep habits that determine whether or not you receive a good night’s sleep as sleep hygiene. Below you’ll find a comprehensive list of the internal and external factors that will influence your sleep.

Stress

Stress is a common feeling that has the ability to influence our sleep. When our bodies are responding to stressful or dangerous situations, often we’re left lying awake in bed wondering how we can get some rest. “Stress typically tends to lighten sleep,” says Winter. “We become much more aware of arousals or it makes it more difficult for people to get to sleep or even fall back asleep if they wake back up.”

The same sleepless outcomes are often reported by those who have anxiety, depression, and other mental health conditions that have a tendency to influence our sleep duration and sleep quality.

Aches & Pains

It comes as no surprise that aches and pains in any form will influence our sleep. Be it muscle or joint pain or even a simple headache, these conditions bring on the discomfort that makes it difficult to fall asleep and stay asleep. “The quality of the sleep also influences how we heal,” notes Winter. “If you’re not sleeping well because of the pain, it makes it harder for you to get past the pain.”

Stimulants

Though a cup of coffee may seem enticing in the late afternoon as you try to make it through the day, the boost of caffeine can wreak havoc on your sleep.

“This can easily be a double-edged sword,” says Winter. “I may need stimulants like coffee to get through my day and not fall asleep behind the wheel, but if I take them too late or the timing is off, it really does influence how I sleep or how I feel.” Other stimulants such as alcohol can also interfere with a good night’s sleep. As a result, it’s best to avoid all stimulants before bed, even if they make you drowsy.

Shift Work

Shift work has the ability to alter your body’s circadian rhythm, which naturally determines when you feel sleepy, when you feel awake, and how often you wake during the night. Because shift work manipulates when you go to bed, your body’s internal clock will grow confused as it tries to find sleep patterns within your changing schedule.

“It’s not just sleep we’re talking about,” says Winter. “ Everything in our body is timed. It all works on a schedule, and when the schedule is in flux, it creates significant problems for the body beyond just feeling exhausted and poorly rested all the time.”

Sleeping Environment

A sleeping environment that contains loud music, bright lights, and distracting electronics is no place to get healthy sleep. “That 24 hours of technology really does affect the brain in negative ways and sleep in negative ways as well,” according to Winter. Your sleep environment should be quiet and free of any distractions that prevent you from falling asleep and staying asleep.

Sleep Disorders

“Sleep disorders are so much more common than people know,” says Winter. “They’re some of the most commonly undiagnosed disorders out there.” Disorders such as insomnia or sleep apnea influence the sleeping habits of millions around the world.

Whether these disorders are short-term problems or chronic issues, poor sleep as a result of a sleep disorder will stop you from getting the rest your body and mind crave. Sleep medicine can help you sleep better, but you should discuss your options with a healthcare provider before determining what you can do to overcome a sleep disorder.

Sleep Tracking With Modern Technology

Now that we have a solid understanding of how we sleep and what factors will influence our sleep, it’s time to examine sleep analysis in greater detail. To analyze our sleep, we rely upon sleep trackers, smartwatches, and other wearables that contain technology capable of monitoring sleep patterns.

Wearable sleep trackers will often do more than simply track sleep. In fact, many of these devices are fitness trackers that record your physical activity throughout the day and night.

For instance, a biometric tracker will monitor and analyze your sleep, as well as track other health metrics such as your heart rate and oxygen saturation. After the data has been recorded, it will sync with your phone via a health app that provides digestible information about your sleep habits.

“These devices can really help people understand when you’ve moved past what you can do on your own,” says Winter. “The field of sleep is wide open, and these devices might help you understand when you’ve progressed well past something you can fix by yourself.” If a sleep tracker is reporting information that you need help understanding or resolving, bringing that data to a sleep doctor or physician can be a crucial step toward achieving better sleep and better health.

Most devices that are capable of sleep tracking are worn around the wrist. These pieces of tech contain an accelerometer that detects body movements to determine whether you’ve had a restful or restless night of sleep. Some devices include sleep coaching technology that provides suggestions to help you get better sleep if there’s room for improvement.

Advanced sleep trackers will go one step further by evaluating your sleep quality based on the different sleep stages described above. These devices can produce graphs or visuals that pinpoint the amount of time spent in each sleep phase, thus highlighting when you slept well and when you didn’t.

Get Better Sleep With Sleep Analysis

These fancy devices aren’t just for show. The data they provide can help you get better sleep by providing critical insights into your nightly sleeping patterns. But remember that the information collected by these devices is only as useful as you make it out to be.

Tracking your sleep is important, but so is implementing healthy sleep habits that include eliminating distractions and seeking professional help if need be. Invest in a sleep tracker to analyze your sleep, learn what your sleep patterns are over time, and decide if you need professional help to get the healthy sleep your body and mind deserve.

Modern diets are a dime a dozen. Scrolling through social media, you’d think everyone was on some sort of diet the way they’re discussed in such fervorous detail.

The ketogenic diet, or “keto diet” for short, eliminates carbs entirely and is a favorite of bodybuilders. The South Beach Diet insists a low-carb approach is the healthiest diet for you heart. And even eating techniques like intermittent fasting are diets in their own unique way, suggesting we eat during specific periods of time throughout the day while restricting food entirely during others.

Truth be told, there’s no single diet that solves every problem, nor is every diet safe for every person. That being said, there are eating methods we can adopt that utilize the basic principles of a diet alongside simpler rules for consumption. One of these diet plans that’s proven to have a significant effect on one’s health is referred to as carb cycling.

No, this method doesn’t involve eating a bowl of pasta before spending hours on a bicycle. Instead carb cycling is a diet plan that seeks to simplify carbohydrate intake over a period of time, thus leading to weight loss as a result. But before we delve too deeply into the process of carb cycling, let’s begin with the basics. Let’s start with the simple carbohydrate.

What Is a Carbohydrate?

There are three main macronutrients that our body gets from food: fat, protein, and carbohydrates. Fat is stored in large amounts throughout the body and acts as a slow-burning fuel. A gram of fat contains 9 calories. Protein, on the other hand, is used to make hormones, build muscle, and create enzymes. A gram of protein contains 4 calories. And finally, carbohydrates are stored in the body as glycogen and act as the main fast-burning fuel source for the body and brain. A gram of carbohydrates also contains 4 calories.

While carbs may serve a number of functions, their primary responsibility is to provide the body with a source of energy. They’re the body’s most readily available form of fuel. Yet because our body will only need a certain amount of fuel from carbohydrates each day, excess carbs are converted to fat for future use when needed. But often times such stores of fat can go unused, thus contributing to an increase in body weight over time.

The solutions we can utilize to combat this conversion of carbohydrates to fat are numerous. For instance, we can attempt to burn fat and carbs by exercising regularly. We can reduce our calorie intake each day or practice healthy eating habits that provide fewer carbs. Or we can adopt a technique like carb cycling, which aims to match the body’s need for glucose with a specific activity, or our overall activity levels. That final option remains one of the healthiest ways to regulate our carbohydrate intake.

So How Does Carb Cycling Work?

You may now be wondering how exactly carb cycling works. If the intent is to match the body’s need for carbs, what measures can we take to ensure this occurs?

When breaking down the carb cycling procedure, we must start by discussing how we use carbs during different carb cycling days. While most people are generally consistent in terms of daily carbohydrate intake, carb cycling seeks to manipulate intake in a regimented fashion. These days can be categorized as high-carb days and low-carb days.

High-Carb Days

Think of all the food you’ll consume on any given day. Most of us will incorporate breakfast, lunch, dinner, and snacks between meals. Yet as we all know, higher-carb days are bound to occur throughout any given week. Perhaps your morning will start with a bagel, and the night will end with a hearty bowl of pasta, followed by a slice of cake for dessert. When days like these occur, and we’ve increased our carb intake more than we otherwise would, this is considered a high-carb day.

So what do we do when we’ve got a day ahead of us that’s chock-full of carbs? Ultimately, our goal is to match that increased intake of energy-dense macronutrients with high-intensity workouts that are sure to burn the carbs off.

When we exercise at high-intensity, our body requires more fuel from carbohydrates to meet the increased energy demands. By breaking down the carbs either aerobically (with oxygen) or anaerobically (without oxygen), the body is using more carbohydrates during the workout itself, as well as after the workout to make glycogen to refuel and decrease muscle breakdown.

Low-Carb Days

So what happens if the day is reversed? You’ve eaten far fewer carbs, and instead have relied on healthy fats like avocado or protein from meat and veggies as opposed to that plate of pasta.

This is the other end of the spectrum that completes the cyclical carb “cycle.” While it was once believed that low-carb days ensured little need for exercise, recent research has instead suggested that training on low-carb days can still serve a purpose by speeding up any adaptations to aerobic training while increasing fat burning and thus improving endurance.

By participating in days of low-carbohydrate consumption, the body is forced to rely on fat as the primary form of energy, thus increasing aerobic capacity, defined as “the maximal amount of physiological work that an individual can do as measured by oxygen consumption.”

However, the body must grow accustomed to a diet that reduces the total amount of carbs if it’s to burn fat on a consistent basis. While fat loss is often a product of utilizing the carb cycle, the body will still be dependent on carbs in the short-term before progressing to fat as the primary energy source.

A Carb-Cycling Schedule

Though the schedule below leaves room for customization, this is a solid example of your typical carb-cycling routine. Remember that lower-carb days can still be accompanied by exercise, but high-carb days should most certainly be combined with training days, as is standard procedure for the carb cycling diet. The schedule below also fails to address the opportunity for a rest day, but these can be incorporated once per week if needed.

• Monday: higher-carb day
• Tuesday: lower-carb day
• Wednesday: higher-carb day
• Thursday: lower-carb day
• Friday: lower-carb day
• Saturday: higher-carb day/optional reward day to enjoy a favorite meal
• Sunday: lower-carb day

Keeping Your Diet in Mind

While it may be easy enough to keep track of the carbs we consume while exercising accordingly, often our diet and everyday meal plans alone can play a sizable role in our body and brain health. A low-carb diet or even a moderate carb diet that relies on whole foods and high-protein is a common means of altering one’s body composition. When we elect to maintain a healthy diet, many changes can take place.

That being said, it’s important to consult a nutritionist or dietitian when considering an extensive overhaul of your diet. Any form of food consumption that suddenly alters protein intake, fat intake, or carb intake can be dangerous for those with an insulin sensitivity or blood sugar concerns.

Additionally, weight loss in any form is a product of both diet and exercise. According to Shawn Talbott, nutritional biochemist and former director of the University of Utah Nutrition Clinic, “weight loss is generally 75% diet and 25% exercise.” It’s not a product of diet alone. To ensure we’re establishing our exercise routine alongside this new diet plan, we can use measurement techniques like the rate of perceived exertion scale, to make sure we’re exercising at the correct level for our personal fitness.

The most difficult aspect of carb cycling tends to be sustainability. While we can go perhaps one or two weeks on any given diet plan, low-carb diets are no easy task. As a result of this reality, medical professionals often recommend striving for a more balanced plan that focuses on fruits and veggies, lean proteins, and whole grain carbs.

Because cutting calories too low can lead to a decrease in muscle mass, the general rule of thumb is to allow 10 calories per pound of body weight — so a 125-pound person should strive to consume 1,250 calories per day, thus leading to weight loss no matter how much you exercise.

Is Carb Cycling for You?

Determining whether or not you should participate in a carb cycling diet requires research and experimentation based on your lifestyle and fitness routine. Striking a balance between high-carb and low-carb days is a process that can change in the long-term, so be patient and pay attention to your body as you go. Incorporating exercise and even consistent sleep are other necessary tools to ensure your carb cycling is as effective as possible.

To learn more about carb cycling, be sure to consult a nutritionist or dietitian rather than go it alone. Carb cycling allows for flexibility and empowers choice, making it one of the most popular diets in that ever-expanding catalog of dieting options. And it could be a more sustainable option for carb-cutters with a love of pasta.

Our body works endlessly to keep up with our daily demands. From getting out of bed in the morning to sprinting up a hill, we put bones, ligaments, and muscles to the test, each and every day.

Sometimes our body experiences pain and discomfort as a result. Maybe deadlifts at the gym lead to back pain, or a sports injury causes chronic pain that you can’t seem to shake. To treat these aches and pains, we can employ a wide variety of techniques and treatments — from general stretching to physical therapy and beyond.

One form of treatment to alleviate pain and promote healing is microcurrent therapy. Used to treat a wide variety of injuries, microcurrent therapy will apply electrical currents to specific parts of the body to help tissues heal faster while providing pain relief along the way. Let’s take a deeper look at this form of pain management to see what the buzz is all about.

How Does Microcurrent Therapy Work?

Also known as electrotherapy or microcurrent stimulation, microcurrent therapy uses electrical energy to help reduce pain, repair tissue, strengthen muscles, promote bone growth, and more. But how exactly does it work?

Believe it or not, your body is a conductor of electricity that produces an electrical charge of its own. Cells conduct electrical currents to communicate with one another, and your nervous system uses electricity to send signals throughout your body and brain. These signals allow us to move, think, and feel.

When your body suffers from an injury, this necessary signaling is disrupted or hindered. Without the proper signals between cells, your body can’t operate efficiently.

Microcurrent therapy aims to restore the electromagnetic communication between cells in order to promote healing and provide relief from muscle pain or joint pain. Additionally, microcurrent therapy is used in spas for its anti-aging properties to contour, tone, and firm aging skin, often on the face.

Using microcurrent therapy to increase cellular communication helps stimulate your body’s production of ATP, or adenosine triphosphate, in the injured tissue. ATP is the body’s primary source of energy that allows cellular interactions to take place. Microcurrent therapy works to increase ATP production by as much as 500% in damaged tissue — an increase that can help with the recovery process.

Microcurrent Therapy vs. Transcutaneous Electrical Nerve Stimulation

Microcurrent therapy is often confused with a different form of electrical therapy known as transcutaneous electrical nerve stimulation, or TENS for short. While TENS uses mild shocks that you can feel under the skin, microcurrent therapy uses electrical currents that are extremely weak, so you won’t feel a thing. TENS offers short-term relief from pain and inflammation, while microcurrent therapy offers long-term relief and healing properties.

What Conditions Can Be Treated With Microcurrent Therapy?

Microcurrent treatment has the ability to treat a wide variety of issues, but it is often used to treat nerve and muscle pain, or reduce scar tissue and inflammation due to the following conditions.

• Fibromyalgia
• Myofascial pain
• Arthritis
• Carpal tunnel
• Sprains
• ​Concussions
• Bell’s Palsy
• Headaches
• Burns
• Asthma
• Irritable bowel syndrome
• Low back pain
• Disc injuries

How Is Microcurrent Therapy Administered?

The microcurrent therapy application process is simple. First, a therapist applies a moistened towel or self-adhesive electrodes to the affected area. Then he or she sets frequencies on the microcurrent device that correlate with the condition being treated. This process is referred to as frequency-specific microcurrent therapy, as the frequencies will change depending on what the injury is and where it is on the body.

Once the therapy is applied to the skin, electric currents will act as a stimulator to help repair damaged tissue and provide pain relief. Be sure you’re well-hydrated before receiving microcurrent treatment in any form, as this further promotes electrical stimulation. Your cells are composed largely of water, and well-hydrated cells will better conduct the electrical current with one another.

If you’re receiving a microcurrent facial, two metal prongs will mildly shock the face in specific locations. Though this process may sound intense, it’s both safe and FDA-approved.

Is Microcurrent Stimulation Painful?

Treatment with microcurrent stimulation is a noninvasive, injection-free procedure that’s generally painless. The electrical currents used to treat injuries are administered in doses so low that the patient rarely feels them. The only effects you may notice include a warming sensation, tingling, or softening of affected tissues.

How Long Do the Effects Last?

The effects of microcurrent therapy, including pain relief, can last for several days or longer depending on the injury being treated. For acute injuries, lasting pain relief can be achieved, though multiple sessions of therapy may be necessary.

The Benefits of Microcurrent Therapy

As you may have guessed, microcurrent therapy can be used to treat many things. From sports injuries to wounds to sagging skin, it’s a healthy form of therapy with lasting benefits. Microcurrent therapy can:

• Reduce neck, joint, hip, and back pain
• Heal tendons
• Reduce muscular degeneration
• Lessen headaches
• Improve symptoms of diseases like arthritis or fibromyalgia
• Tone the skin and promote collagen production

The Risks and Side Effects of Microcurrent Therapy

The risks that come from microcurrent therapy only apply to those who have pacemakers, implanted pumps, uncontrollable seizures, or women who are pregnant.

While low-level electrical currents aren’t dangerous, they can interfere with the body’s electrical signals in those who already suffer from conditions that affect the body’s electrical system, such as epilepsy or multiple sclerosis. Speak with your doctor or a licensed physical therapist before utilizing microcurrent therapy to determine whether it’s right for you.

How Much Does Microcurrent Therapy Cost?

While microcurrent therapy is often covered by your insurance and used in conjunction with other recovery aides, you can also seek this form of therapy on your own. Whether you’re seeking pain relief or simply want a microcurrent facial, microcurrent therapy can cost anywhere from $250 to $500. This depends largely on where you go (some cities such as Los Angeles or New York City will charge higher prices) and what you wish to treat.

Professional Treatment Versus At-Home Devices

If shelling out hundreds of dollars for microcurrent therapy isn’t your cup of tea, at-home devices are available for the price of one or two professional sessions. While these devices are available in abundance for your face, you can also find others that treat your body as well, though these may be more expensive.

And don’t expect the results to come immediately should you choose to purchase your own device. You may need to administer the therapy consistently for 60 days or more before seeing any results should you choose at-home treatment — these personal devices are often weaker than the devices used during professional treatment.

Practical Pain Management With Microcurrent Therapy

Various therapies seek to provide pain relief and healing in some form or another. From pain medications to invasive surgeries, there is much we can do to alleviate injury and pain. Fortunately, treatment options such as microcurrent therapy can provide non-invasive relief and healing.

While administering electrical currents to your body in an effort to promote nerve stimulation may sound intimidating, this lesser-known form of therapy has been used for decades without fail. If you find yourself suffering from muscle pain, nerve pain, or damage beneath the surface, take some time to determine if microcurrent therapy is right for you.

Whether you had too much coffee too late in the day or your mind is racing with thoughts, we all struggle with restless sleep from time to time. But, what happens when your sleep always feels restless, no matter what you do?

This could be a sign that something else is the culprit. Specifically, certain sleep disorders could unknowingly be causing your sleep problems and disrupting your ability to sleep well. If you’re suffering from restless sleep, here’s a look at the most common reasons people have sleep issues, plus what you can do to improve your sleep quality to get a good night’s sleep every night.

The Dangers of Restless Sleep

Restless sleep is characterized by frequent sleep disruptions throughout the night. When a person is constantly tossing and turning, as well as waking frequently, their sleep can be classified as restless. One of the greatest dangers of restless sleep is that it leads to sleep deprivation, which contributes to a host of additional problems.

For one, sleep deprivation causes severe fatigue that can slow a person’s reaction time. When a person can’t react quickly to changes in their environment, they’re more likely to get into an accident or hurt themselves. In fact, The National Highway Traffic Safety Administration estimates that fatigue leads to 100,000 car crashes and 1,550 crash-related deaths per year in the United States.

Restless sleep also leads to excessive daytime sleepiness that impairs a person’s functioning at work, which can further endanger their safety and compromise their quality of life. Aside from sleep deprivation, another dangerous side effect of chronic restless sleep is that it can lead to an over-reliance on sleep medicine.

A few signs that you’re taking too much medicine for sleep include: using sleeping pills to treat anxiety, taking extra doses of sleeping pills, and taking a second pill after waking in the middle of the night. While sleep aids can be helpful in certain situations, becoming dependent on them can further disrupt your body’s ability to sleep and function normally.

Restless Sleep and Sleep Disorders

When you’re experiencing restless sleep, the first thing to consider is a sleep disorder. Many people who suffer from lack of sleep have sleep disorders without even knowing that a medical condition is causing their distress. That’s why it’s important to be aware of the disorders that contribute to trouble sleeping and to understand how they can interfere with your ability to get quality sleep.

Restless Legs Syndrome

Restless legs syndrome is one of the most common sleep disorders that can cause sleep disturbances. Also known as RLS, restless legs syndrome is characterized by uncomfortable sensations in the legs. This can include cramping, twitching, or even tingling feelings that cause the sleeper to move in order to relieve the discomfort.

These feelings persist throughout the night, distracting the person sleeping and making it hard to stay still and fall asleep. Restless legs syndrome also tends to wake people once they’ve fallen asleep, making it hard to maintain sufficient sleep throughout the night.

Narcolepsy

Narcolepsy is another sleep disorder that’s often associated with restless sleep. While people with narcolepsy tend to feel rested after waking up, they usually feel the urge to fall asleep again shortly after. This extreme urge to sleep can strike a person in the middle of any activity, including talking or driving. Narcolepsy is a neurological disorder that disrupts a person’s sleep-wake cycle, or circadian rhythm.

In addition to experiencing overwhelming sleep attacks throughout the day, a person with narcolepsy may also experience cataplexy: a sudden loss in muscle tone that causes a person to collapse. While it sounds scary, it’s quite similar to the paralysis that all people experience during REM sleep.

Narcolepsy can also cause sleep paralysis, in which a person is unable to move when entering or leaving REM sleep. Sleep paralysis is when a person is conscious and knows they’re awake, yet they’re unable to move.

Obstructive Sleep Apnea

There are three main types of sleep apnea: obstructive sleep apnea, central sleep apnea, and mixed sleep apnea. Obstructive sleep apnea is the most common type of sleep apnea and is when a person stops sleeping periodically throughout the night. This occurs because their airway is too tight or floppy for the breath to flow smoothly from the mouth and nose into the lungs.

These disruptions to the person’s breathing most commonly cause snoring but can also lead a person to wake during the night gasping for air. This causes restless sleep because a person may wake multiple times during the night due to airway obstruction. These frequent disruptions can lead to forgetfulness, daytime drowsiness, poor sleep quality, and irritability throughout the day.

Rapid Eye Movement Sleep Behavior Disorder

Rapid eye movement sleep behavior disorder (RBD) is a sleep disorder that occurs during REM sleep, which is the dream phase. Instead of staying still like most people during dreaming, a person with RBD will act out their dreams as if they’re awake, says the National Sleep Foundation.

In some instances, this can involve tossing and turning, thrashing, sleep talking, hitting, or even shouting. More extreme cases involve people getting up out of bed, sleep walking, and engaging in other activities — all while still asleep.

It’s important to understand that rapid eye movement sleep behavior disorder usually happens when a person is dreaming vividly. When these dreams are frightening or unusual, the person suffering from RBD may scare themselves or their partner. This can lead to restless sleep because a person may wake themselves by moving or walking about, or their partner may wake them if they’re engaging in violent behavior.

Lifestyle Changes to Improve Sleep Hygiene

Suffering from sleep problems can be a major detriment to your quality of life, but there is hope. Using a sleep tracker is one of the best ways to understand everything about your sleep patterns, since many issues can arise without your knowledge — especially if you don’t sleep with a partner. Even people who suffer from narcolepsy can improve their sleep hygiene by following a consistent sleep schedule and adhering to the following healthy daily habits.

Establish a Bedtime Routine

When you do the same thing every night before bed, your body begins to associate these activities with feeling tired and getting rest. These activities should include relaxing activities like reading, stretching, or listening to music. Similarly, it’s important to only use the bedroom for sleep and relaxation — working on the computer while in your bed can associate the space with the need to be alert.

Avoid Stimulants That Keep You Awake

Most people understand that drinking coffee late into the night can disrupt their sleep. But sleep can also be disrupted by things like drinking alcohol, exercising, and napping too close to bedtime. All of these things can make you more alert when it’s time to get some shuteye, increasing the chances of waking during the night.

Try Melatonin

You can also improve your sleep quality by adding more sleep supplements to your daily regimen. For example, supplementing with melatonin may help with REM sleep behavior disorder. Melatonin has fewer side effects than chemical sleeping pills, and it can offer nearly the same benefits. Since melatonin is a naturally occurring hormone, taking more melatonin can help you sleep better throughout the night.

In addition to supporting a more regular sleep wake cycle, melatonin also regulates body temperature, blood pressure, and hormone levels. Specifically, research says that melatonin “binds to receptors in the brain to help reduce nerve activity. In the eyes, it can help reduce dopamine levels, a hormone that helps you stay awake.”

The greatest benefit of melatonin for people with restless sleep is that it can help a person stay asleep. This is primarily due to the reduction of dopamine and nerve activity, which can keep a person alert late into the night.

Improving Sleep Quality for More Restful Nights

Spending an entire night in restless sleep isn’t fun for anyone. In fact, people who have chronically restless sleep are more likely to suffer from sleep deprivation, which can lead to a host of challenges and dangers.

Restless sleep may or may not be caused by a sleep disorder such as restless leg syndrome, RBD, sleep apnea, or narcolepsy. Taking a look at your sleep habits and overall sleep hygiene can help you understand where you’re missing out on sleep — and how you can catch up.

The nervous system is a fascinating and complex network of nerves, synapses, and organs that work together to transmit signals throughout your body. It’s one system in a larger environment, and it’s responsible for everything from movement to unconscious acts like adjusting your vision and maintaining your resting heart rate.

Want to learn more about the parasympathetic nervous system and why it matters for your health? We’ve put together this scientific guide to help you understand how the system works. Plus, you’ll learn what it means for your health and how you can use tools to track metrics and monitor your wellbeing.

What Is the Parasympathetic Nervous System?

Understanding the parasympathetic nervous system (PSNS) can be complicated because it’s part of a much larger network of bodily processes. Essentially, the parasympathetic nervous system, also known as the “rest and digest” system controls bodily functions associated with the body at rest and after digestion. To fully understand this system, you need an overview of the network it works within.

Your body is a complex network of cells and structures that come together to drive movement, create thoughts, and sense the world around you. Within these complex networks, the nervous system plays a key role. The nervous system consists of nerves and neurons that work to transmit signals from one part of the body to another. It’s the process that underlies everything from waving your hand to coughing to standing up.

The nervous system consists of two parts, the peripheral nervous system (PNS) and the central nervous system (CNS). The brain, spinal cord, and nerves make up the central nervous system while neurons and clusters of neurons — known as ganglia — are the key actors in the peripheral nervous system.

Since these systems are so complex, scientists have broken them down even further. The peripheral nervous system is divided into two sections: the autonomic nervous system and the somatic nervous system.

For our discussion of the parasympathetic nervous system, we’ll focus on the functions of the autonomic nervous system, which controls involuntary smooth muscles and glands. The parasympathetic nervous system is one of two subsections of the autonomic nervous system. The autonomic nervous system is responsible for things you can’t voluntarily change at a moment’s notice, including your heart rate and digestive functions.

Now that you have a basic grasp of the entire nervous system, we’ll dive into the functions and actors of the parasympathetic nervous system.

Functions of the Parasympathetic Nervous System

The parasympathetic nervous system is one of two divisions of the autonomic nervous system. The other division of the autonomic nervous system is the sympathetic nervous system. That system is responsible for the body’s fight or flight response.

On the other hand, the PSNS controls unconscious movements and signals that occur during a variety of activities. The parasympathetic nervous system is what’s working behind the scenes when you cry, when you digest and process foods, and when you start drooling over a delicious meal. It’s responsible for everything from urination and defecation to sexual arousal.

It works to constrict certain eye muscles to help improve vision at close range, and it makes it easier for you to use the bathroom. It works like this: M3 receptors — which help to slacken smooth muscle — are stimulated to relax the urethra, which makes it easier to urinate. In scientific terms, parasympathetic stimulation signals peristalsis in the ureters — an involuntary constriction that relaxes urination muscles, creating a wave-like effect that moves the contents of your bladder toward the urethra. In essence, the PSNS is responsible for the urge to use the bathroom. Some of the main functions of the parasympathetic nervous system are that it:

• Stimulates salivation
• Constricts pupils
• Contracts the bladder
• Inhibits the production of adrenaline
• Decreases heart rate
• Stimulates digestion
• Relaxes sphincter muscles
• Dilates bronchial tubes

The parasympathetic nervous system essentially works behind the scenes to keep things running as smoothly as possible. It’s a system you may not think much about, but it is a key part of most of your daily routines.

Actors Within the Parasympathetic Nervous System

The parasympathetic nervous system operates mainly within the lungs, heart, bladder, and stomach. It sends signals using parasympathetic nerves — special nerve systems that are rooted in the spinal cord — and cranial nerves, which are rooted in the brain. The system triggers bodily functions when signaled by parasympathetic nerves throughout the body. The main parasympathetic nerves are autonomic or visceral nerves that work with two neurons to carry signals to the target organ.

Cranial nerves are also among the key actors in the PSNS. The body has a total of 12 cranial nerves that are rooted in the nuclei of the brain and spread out to vital organs. Because of this structure, the PSNS is often said to have a craniosacral flow — a flow of information from the brain to other organs.

The cranial nerves carry signals from the brain to ganglia — a structure that consists of cell bodies including neurons. These ganglia comprise four parasympathetic synapses including the ciliary ganglion, which control pupil dilation, and the pterygopalatine ganglion, which produce tears and mucus. The other two synapses include the otic ganglion and the submandibular ganglion, which control salivation.

These signals are transmitted through nerve fibers known as preganglionic fibers. After the ganglion processes the message, the PSNS sends the singnal to the relevant organ, using fibers known as postganglionic fibers. The nerve fibers also contain neurons that are involved in the transmission process and known respectively as preganglionic neurons and postganglionic neurons.

Think of the parasympathetic ganglia like train stations — a train arrives with a passenger holding a briefcase of information and departs to deliver that briefcase to another location. You can also think of it as a post office. A letter or message comes through the postal depot and is then transmitted out to its destination.

In the PSNS, there are 4 main nerve types that perform most actions.

• Oculomotor nerve: This cranial nerve is located in the eye and is responsible for constricting the pupil. This makes the pupil smaller, bringing in less light. It also contracts the ciliary muscle — an eye muscle responsible for vision — helping to improve vision at close distances.
• Facial nerve: The facial nerve is responsible for controlling the salivary glands and glands in the mouth and nose. This parasympathetic nerve also controls the lacrimal glands, which produce tears.
• Glossopharyngeal nerve: This nerve delivers signals to the salivary glands known as parotids glands.
• Spinal nerves: Spinal nerves are made of desiccated pathways from the spine to the heart that help manage overall heart control.
• Vagus nerve: The vagus nerve originates in vagal nuclei that are responsible for an incredible amount of body functions. According to StatPearls, the vagus nerve acts on “the viscera of the abdomen and thorax” and is especially important because it “carries 75% of all parasympathetic fibers”. The nerve delivers messages to a host of organs from the bladder and stomach in the gastrointestinal tract to the kidneys, liver, and sexual organs.

Why the PSNS Matters

The parasympathetic system is incredibly important when it comes to normal bodily functions. If something within the system breaks down, you may develop issues including digestive problems and heart problems. The latter is particularly important since the PSNS plays an important role in heart health that we haven’t covered yet.

The PSNS includes special heart receptors known as muscarinic receptors. The function of these receptors is to prevent stimulation from the other autonomic system — the sympathetic nervous system, which triggers the fight or flight response in stressful situations. Research shows a correlation between sympathetic nervous system activity and negative outcomes in patients with heart failure.

On the other hand, parasympathetic nervous system activation may help to protect heart health. That’s because these systems work in parallel. While the sympathetic nervous system can trigger increased heart rate and fight or flight responses, the PSNS tends to relax and constrict body responses.

Additional research shows the parasympathetic nervous system may help protect heart health by regulating blood pressure and heart rate. This system sends signals for vasodilation — or widening — of the blood vessels, helping to lower high blood pressure.

The PSNS may also help regulate the resting heart rate. A normal resting heart rate is between 60 and 100 beats per minute. If you’re not sure what your resting heart rate is, you can easily calculate it at home.

Use a health tracker like Biostrap’s wristband to get accurate readings of your resting heart rate. Alternatively, you can take your heart rate by placing two fingers on your wrist and counting the number of beats for one minute. If your resting heart rate is abnormal, it may be a sign that something within the parasympathetic nervous system isn’t working properly.

The PSNS and Your Health: How to Monitor Metrics

The parasympathetic nervous system is a key component of overall health. It’s responsible for unconscious movements that are vital to digestion, vision, and heart health. Monitoring your health can help you identify underlying issues that may affect your PSNS and other important health networks.

The Biostrap App and wearables are a great way to track and monitor your health. From monitoring your resting heart rate and oxygen saturation levels to tracking your sleep habits, the tool offers unrivaled insights into your health.

Mobility, balance, and flexibility are frequently overlooked but essential elements of well-rounded fitness.

Improving or maintaining good balance and mobility help you feel and look your best. In addition, it helps you move well as you age.

On the surface, it may appear that balance and flexibility training have little to do with heart rate variability (HRV). That is true, however the activities that help develop these areas of fitness also tend to promote concentration and relaxation.

Mind-body activities like yoga, dance, tai chi, surfing, and some sports challenge balance, require careful fluid movement, require carefully timed breathing and use full ranges of motion. This combination of factors results in flowing movements where the participant staying focused throughout the activity. The focus and flow has a meditative effect for many people and can help participants destress and can help stats like HRV, resting heart rate, and blood oxygen saturation improve over time.

Benefits of Balance & Mobility Training:

Balance is skill that typically declines with age. However, even among younger people, those with excellent balance perform better in their favorite activities and are at a lower risk for accidents and injury. Preserving balance grows more essential the older one gets as it is in many ways a “use it or lose it” type skill. Since it is a skill, you can improve it through exercise.

Harvard Medical School said “balance training helps reduce the risk of falls in older adults.” This is especially beneficial to older adults with thinning bones as a broken leg or hip can have devastating consequences for older adults.

In addition, in the mid-200’s a Brazilian study indicated that older adults who can sit on the floor then rise to standing position without aid of their hands were much less likely to die within the next 6 years than those who could not. The study made a splash in the media, although some question how valid it was especially in the case of injury or disability. Older adults who can complete the task maintained good balance, mobility, flexibility, core strength, and lower body strength. Those qualities are all associated with longevity in numerous other studies.

Other benefits include:

• Improved posture which leads to an improved appearance
• Grace and ease of motion
• Being less prone to accidents and injuries
• Relieved stress
• Decreased pain in many cases
• Improved sports, work or activity performance

How To Improve Balance, Flexibility, and Mobility

Core strength helps with balance, so many core exercises like planks help develop balance skills. Most activities that challenge your balance will help improve your balance, spatial awareness, and control. Some examples include climbing, surfing, dancing, yoga, circus inspired workouts, and tai chi. Also simple exercises like standing on one leg help.

Flexibility and mobility exercises can be in a stand alone workout sessions such as a yoga class. Or if you prefer, you can incorporate them into your cool down from your aerobic or strength training workouts.

The Mayo Clinic recommends stretching after more vigorous workouts while your muscles are warm. The American Council on Exercise recommends stretching and doing mobility exercises daily if possible or at least three times a week.

“Lack of mobility is associated with poor posture and pain, which can affect the ability to perform even the simplest daily routines.” The American Council on Exercise.

Mobility exercises are related to stretches but tend to be more dynamic. For example, someone might do gentle hip circles to aid their hip mobility. Dynamic stretching, tai chi, flowing yoga poses, and many gentle sports warm up exercises are all examples of mobility training. People often incorporate these exercises into their workout warmup.

A balanced fitness program includes exercises designed to improve all aspects of fitness including aerobic training, strength training, balance training, and flexibility or mobility training.

Simple Sitting Test Predicts How Long You’ll Live, Discover

Finland gets cold. Its territory runs far above the arctic circle and its not uncommon for temperatures to be in the -20s or lower. Could there be a better territory for a man who has been dubbed “The Iceman” for his uncanny feats in the cold extremes?

In January of 2007, the temperature in Finland was -35 degrees. Wim Hof, barefoot and in shorts, would run the world’s fastest half marathon barefoot and in snow, clocking in at just over 2 hours—and this is just one of many instances where Hof pushes his body to the limits.

Wim holds 26 Guinness World Records in all. He has topped Mount Kilimanjaro and climbed much of Everest in just shoes and shorts. In 2011 he would also run a marathon in the Namib Desert without water.  Wim has completed feats that are simply unexplainable. They defy science, yet they have happened under the watchful eye of scientists.

Perhaps the most incredible feat that was monitored by scientists took place in the Netherlands where Wim submerged himself in a cylinder of ice water for nearly two hours. He was able to sustain a core temperature for the whole time and was under the watchful eye of a UMC scientist professor Maria Hopeman.

The only thing that may be more astounding than his feats is the fact that he believes anyone can do these things!

The Wim Hof Method

Wim has since created and documented a method, The Wim Hof Method, that he uses to achieve these radical feats. His school of thought has slowly been gaining traction in the body hacking community, as people find how to manipulate their bodies to perform miraculous feats. The method is largely based on these three pillars:

1. Cold Therapy

This pillar is explained as proper exposure to cold and it is said to have an incredible amount of health benefits.

Proper exposure to the cold starts a cascade of health benefits, including the buildup of brown adipose tissue and resultant fat loss, reduced inflammation that facilitates a fortified immune system, balanced hormone levels, improved sleep quality, and the production of endorphins

https://www.wimhofmethod.com

2. Breathing

The Wim Hof breathing method is used to saturate the body with oxygen. It involves a steady influx of deep breaths and will make you feel lightheaded. This rush of oxygen to the body also has tremendous health benefits

3. Commitment

The final and most important pillar of all is the commitment. It’s the commitment to the cold and the to the breathing. If you can commit to this Wim believes that you can achieve the feats and health benefits that he has as well.

Why it works: Manipulation of Sp02 and HRV

So, what does science have to say about this real life cryomancer? It would seem he is impervious to cold, disease and discomfort in general. Wim has been characterized as an autodidact who has the ability to control his bodies circulation

The isolation of two key biometrics allows the WHM or Wim Hof Method to be measured not just in the man himself but in anyone who attempts his method. These markers are called SP02 and HRV.

SP02 or Blood Oxygen Saturation

“is a measure of how much oxygen the blood is carrying and can be measured using a pulse oximeter without using a needle. This is a percentage of how much oxygen is in your blood compared to the maximum it is capable of carrying.”

How it applies to the WHM:

In relation to Wim’s success he uses a method that will oversaturate the blood with oxygen. In this way he is able to get blood to the parts of his body that need it. This would explain things like being able to run a full marathon, in the freezing cold without much training.

HRV or Heart Rate Variability

Understanding your heart rate variability will help you understand your overall health and how your body is operating. There are two distinct types of heart rate variability and they are very different. While most people assume the heart beats like a metronome it’s not true. In fact, your body is constantly changing process and taking on new duties. These require more or less blood; thus, the heart rate will vary.

Finding out how your heart beats daily routine will give you a hint to what improvements can be made in your own lifestyle.

HIGH HRV

Generally speaking, higher heart rate variability is indicative of the control of the parasympathetic system, one of the two sides of the autonomic nervous system. This system is responsible for regulating the body’s unconscious actions including sexual arousal, salivation, and digestion––often called the “rest and digest” system.

LOW HRV

Low variance in between heart beats, or a consistent heartbeat, indicates a dominance of the sympathetic system. This system’s primary process is to stimulate the body’s fight-or-flight response but, when experienced without a threat, is signaling stress, overtraining, and inflammation.

How it applies to the WHM:

Based on studies the very best method for developing high heart rate variability is through cold therapy. This cold therapy has been measured and studied by many people and the results are resoundingly similar.

Consider this from Todd Becker of gettingstronger.org

“The activity that has delivered the single biggest improvement to HRV for me has been…cold showers!  This has also been the most consistent and most immediate of all the measures I’ve tried.”

“cold showers appear to have improved my stress tolerance, by buffering emotional reactions. What I mean by this is that bad news, surprises, arguments, or events that would have previously caused a brief surge in adrenaline or an emotional flush, no longer have that effect, or at most have a very attenuated effect.”

Measuring the Effects SP02 and HRV in Real Time

There is only one way to see how your body is truly functioning. You can do all the breathing exercises and cold therapy you want but without the ability to measure your blood oxygen levels and heart rate variability you could merely be suffering from the placebo effect.

Pulse Oximetry

When you get sick and head into an urgent care facility, or your primary care physician, you will get a small clip placed on your finger and that is called a pulse oximeter. It checks for a percentage of oxyhemoglobin in the blood stream. This machine will sound if the levels are dangerously low.

Using this tool coupled with some monitoring script, you have the ability to not only measure these levels in your blood but also document them for later analysis.

A complete setup was put together by Alan Reiner of www.alanreiner.com he also documented his results. While the setup was a bit crude and rigged together it open the doors to understanding and measuring the effects of the WHM.

Observe his trial and his setup of the hardware and the script HERE

The Practicality of the Wim Hof Method

While you may not be looking to become the next Sub Zero there are some serious health benefits that have been attributed to this method. The missing link between all of this was having a way to monitor the effects on the body. Biometric tech is lagging behind the tidal wave of science that is hitting the average person. This won’t be the case for very long.

Measuring your body’s performance and understanding how you can affect it with these simple therapies is just one example. If the Wim Hof Method can afford its creator the ability to swing 66 meters under the ice of a frozen lake there are many ways it can help you with your own life goals.

Stress relief and limiting inflammation are two massive health benefits that we can also affect with diet and exercise. How about boosting natural immunity?

While studies and research in this field can stir up tons of questions. I think one stands out more than any other. With robotics and tech advancements stealing the headlines, what is the human body truly capable of?

Sleeping for eight hours a night ensures optimum rest and rejuvenation — or so we’ve been told. Take a quick look into pre-industrial sleeping habits, and you’ll see that the way we sleep is relatively new. What if, instead of giving up the entire night to sleep, we got up in the middle of the night to have more time to ourselves? What if we slept less and napped more?

Scientists, sleep experts, and individuals around the world are waking up to the idea of polyphasic sleep — where sleep is segmented into sections rather than completed in a single stretch. A polyphasic sleep schedule can be used to nurture creativity and mental wellness while reducing daytime tiredness and fatigue.

Find out why great thinkers like Leonardo Davinci, Thomas Edison, and Nikola Tesla all followed a polyphasic sleep schedule, and how it could boost your success and overall health.

What Is a Polyphasic Sleep Schedule?

A polyphasic sleep schedule is just one of many ways to understand and track your sleep. Unlike a monophasic sleep schedule, where a person sleeps throughout the night, a polyphasic sleep schedule involves sleeping in multiple shifts throughout the day.

While there are many ways to achieve polyphasic sleep, it tends to involve resting for 4 to 6 hours total throughout a 24-hour period. Polyphasic sleep differs from ordinary sleep schedules because it doesn’t involve a long stretch of sleep and a long stretch of waking. Rather, it breaks up the entire day into small chunks of sleep and long periods of wakefulness.

Benefits of Polyphasic Sleep

Sleeping multiple times a day can have a number of benefits for certain individuals. This includes increased wakefulness, which provides more time for personal projects, relaxation, or productivity. By realigning your body’s natural rhythms and reducing the fragmentation of sleep phases, polyphasic sleep may also reduce sleep fragmentation and improve overall sleep quality.

“Proponents say that spacing out slumber can maximize the amount of time you spend in rapid eye movement (REM) sleep and slow wave sleep, since the body defaults to these stages when it’s tired,” says Jamie Ducharme at TIME.

REM sleep is important because it regulates mood and fosters dreaming and memory storage, and slow wave sleep restores the body. Taking a 20-minute short nap in REM deep sleep may foster better dream recall than sleeping for 8 hours a day on a monophasic schedule. It has also been said to promote lucid dreaming.

Lucid dreamers are aware that they’re awake during the dream and are able to make choices about where they go and what happens. Increased dream recall and lucid dreaming can lead to a deeper connection with our innermost wants and desires.

Then there’s the obvious perks: Without spending time in the lighter, less restorative stages of sleep, there’s more time in the day to get things done. Whether you want more time to maximize work productivity or you wish to increase internal reflection, there are many reasons why a polyphasic schedule might benefit you personally.

The three primary polyphasic sleep schedules are Everyman, Uberman, and Dymaxion.

Everyman Sleep Schedule

The Everyman sleep schedule is the most common of polyphasic sleeping habits. There are 3 main variations of the Everyman sleep schedule, including Everyman 1, 2, and 3.

Everyman 1 involves sleeping for 6 hours and taking a 20 minute nap during the day (this is technically a biphasic sleep schedule as there are only two instances of sleep involved). Everyman 1 is likely to be the safest and most achievable sleep schedule — one that many people may unknowingly be doing already.

Everyman 2 is when a person sleeps for 4 hours and 30 minutes, but takes two 20-minute naps. And the Everyman 3 sleep schedule involves sleeping for three hours per night and getting rest in the form of three short naps lasting 20 minutes each.

Uberman Sleep Schedule

Followers of the Uberman schedule get 3 hours of sleep per day in total, which is broken up into six 30-minute napping periods. The uberman schedule isn’t realistic for most modern people, as it leads to sleep deprivation and little opportunity for restful REM sleep.

Dymaxion Sleep Schedule

Similarly to Uberman, the Dymaxion sleeping pattern follows a napping-focused schedule. Dymaxion sleepers take four 30-minute naps throughout the day for just 2 hours of sleep in total, making it the least restful polyphasic sleep schedule.

Dymaxion sleep patterns are more popular than uberman, but still aren’t likely to leave a person feeling well-rested. This sleeping schedule was pioneered by Buckminster Fuller, an innovator and visionary from the 20th century. Some say that Fuller may have been able to succeed at this schedule due to a certain gene mutation called the DEC2. People with this mutation only need a small amount of sleep to feel well-rested.

Biphasic sleep schedule

Biphasic sleep is a polyphasic sleep schedule split into just two periods of sleep per day. This could be sleeping during the night and taking a nap during the day, as seen in the Everyman 1 pattern. It may also involve going to bed around nine or 10pm and waking at midnight for an hour or two before returning to bed for a second sleep.

Biphasic sleep patterns aren’t a new invention. In fact, it was the dominant sleep pattern before the invention of electricity. Psychiatrist Thomas Wehr pointed out in 1992 that this pattern was natural for people in the pre-industrial era, especially in areas where there were longer stretches of darkness each day.

People across all continents and cultures used to follow this sleep schedule, adds author and history professor A. Roger Ekirch. He points to the siesta cultures still found in Spain and Italy, where people sleep less during the night and take long naps during the hottest hours of the day. This suggests that biphasic sleep schedules may be part of innate human nature. Natural or not, such patterns were disrupted with the dawn of artificial light. The increase in available light allowed people to do more things later in the evening and early in the morning that otherwise weren’t possible. As a result, they adopted a monophasic sleeping pattern.

Adopting a Segmented Sleep Pattern

A polyphasic or biphasic sleep schedule may work well with certain lifestyles. For example, shift workers like nurses, warehouse workers, or drivers who are employed at night often adopt this method.

This is because it allows them to make up for sleep missed during the normal evening hours without spending the entire day sleeping. College students, creatives, or academics might also benefit from the increased time that segmented sleep provides.

Some people — like those who share Fuller’s gene mutation — might simply rest better this way. “A small percentage of people are night owls, where their bodies and overall well being is actually better at night,” says Dr. Joseph Ojile, founder and medical director of Clayton Sleep Institute.

It’s also interesting to note that many mammals have segmented sleep. Aside from our ever-snoozing cats and dogs, wild animal sleep patterns emphasize survival. Polyphasic sleep patterns allow animals to be more alert throughout the day and night, making it easier to find food and stay safe.

This information tells us that sleeping for eight hours may only be a societal construct. And some, whether due to work or biology, may fare better sleeping less, more often.

Challenges of a Polyphasic Sleep Schedule

Adopting a polyphasic sleep schedule is challenging for most people who sleep just once per day. This is primarily due to our circadian rhythms, which regulate our sleep cycles. These rhythms are what tell our bodies to sleep when it’s dark and stay alert when the sun is up. Fighting against our ordinary waking hours by trying to sleep may be difficult — unless we’re already experiencing sleep deprivation.

Polyphasic and biphasic sleep schedules are also challenging socially. Whether its school, work, or going out, most societal structures are centered around a monophasic sleeping pattern. Trying to get shuteye when your loved ones want to spend time with you — and waking when they’re sound asleep — may disrupt your relationships.

Lastly, sleep deprivation can be harmful to the body both mentally and physically, says the Columbia Department of Neurology. Failing to get enough sleep decreases cognitive function, physical strength, and immunity. When a person experiences long-term sleep deprivation, they’re at a greater risk of depression, mental illness, stroke, and severe mood swings. They’re also faced with an increased risk of car accidents and sleep disorders.

Personalizing Your Sleep Schedule for Better Health

The total sleep time you need depends on your body, your work, and your overall lifestyle. Adopting a polyphasic sleep schedule may be beneficial if you want to increase your sleep hygiene while freeing up more time throughout the day. Whether you choose the everyman, uberman, dymaxion, or biphasic sleeping schedule, there are many ways to alter and improve your sleep patterns for better health both inside and out.

Both the quality of sleep and the amount of time we spend sleeping have been at the forefront of health considerations for quite some time. Recommendations from the CDC suggest adults should get no less than 7 hours of sleep over a 24-hour period.

Adolescents, on the other hand, should get anywhere from 8-10 hours in the same span of time (though two-thirds report getting less than eight hours of sleep each night). And when long-term sleep duration is less than 7 hours per night, the risk of being diagnosed with a chronic health condition like diabetes, asthma, cancer, depression, and even arthritis begins to rise.

While many of us claim to get enough sleep each night, often times we’re simply recalling the amount of time we’ve spent lying in bed. But as most of us know, there’s a stark difference between resting in bed perusing the internet and laying in bed fast asleep. To understand the many facets of sleep quality and quantity, it pays to know a thing or two about sleep efficiency. Let’s learn how to improve sleep through this concept.

The Basics of Sleep Efficiency

Sleep efficiency is the ratio of time spent asleep at night compared to the amount of time spent in bed. For example, if a woman spends 10 hours in bed but only sleeps for 8 of those hours, her sleep efficiency for that night would be 80%. This is calculated by taking the amount of time asleep and dividing it by the amount of time spent in bed, multiplied by 100%. The formula for sleep efficiency would look something like this:

(Time spent asleep / Time spent in bed) × 100 = Sleep efficiency

If, for example, a college student spent 5 hours in bed but only slept for 2 of those hours, their sleep efficiency would be the equivalent of (2 hours asleep / 5 hours in bed) × 100 = 40%.

An individual that spends the majority of their time asleep while in bed is said to be sleep efficient and to possess a high sleep efficiency. But an individual that spends a large portion of time awake while in bed is not considered sleep efficient and possesses a low sleep efficiency, a trait common amongst those with insomnia or other sleep disorders.

As most of us know from years of personal experience, efficient sleep is characterized by very few nighttime interruptions and greater amounts of energy throughout the day. Inefficient sleep, meanwhile, is characterized by sleep disruption that leaves us feeling tired or restless. To ensure good sleep efficiency, the total amount of time spent in bed should be solely devoted to the total sleep time, rather than any amount of time being devoted to waking activities.

Different Sleep Efficiency Rates

Sleep efficiency rates have a tendency to vary from person to person. As a result, sleep efficiency rates are categorized to determine what a healthy rate is and what can be improved upon.

For instance, a sleep efficiency anywhere above 90% is considered very good. A sleep efficiency of 85%-90% is considered normal. Any sleep efficiency rating below 85% is poor, and the individual should strive for more efficient sleep. Sleep efficiency ratings below 75% are poor and can be indicative of sleeping disorders like insomnia. These rates have been outlined in detail below.

• 90% or higher = very good sleep efficiency
• 85%-90% = normal sleep efficiency
• < 85% = poor sleep efficiency
• < 75% = sleeping disorders may arise

Getting to Know the Stages of the Sleep Cycle

In order to fully understand how healthy sleep occurs (and how we can obtain it), it pays to know the sleep cycle stages that we each experience as we drift off into dreamland. These sleep stages can be broken down into five distinct categories, each one characterized by factors that include heart rate, brain waves, and the movement of the eyes when the eyelids are closed.

Stage 1

Stage 1 of the sleep cycle is characterized by light sleep as you drift in and out. Your eyes move slowly, your muscle activity is slow, and you would be easy to wake if someone tried.

Stage 2

In stage 2 of the sleep cycle, your body commences the necessary preparations for deep sleep. Eye movements and brain waves start to slow down, your body temperature drops, and your heart rate slows.

Stage 3

In the third stage you have finally reached deep sleep. Extremely slow brain waves called delta waves are intermixed with smaller, faster brain waves. The movement of your eyes begins to increase as well.

Stage 4

In stage four, you stay in deep sleep and your brain almost exclusively produces slow delta waves, guiding you toward the fifth and final stage of sleep.

Stage 5

Stage 5 is referred to as the rapid eye movement stage, or REM stage for short. During REM sleep, your eyes are closed but they continue to move rapidly from side-to-side. This is due to both intense dreams and the brain activity that occurs in this stage. It is also during this stage and stage 4 that restorative sleep occurs as the body and mind heals itself after a day of being up and awake.

Now that we know how sleep efficiency rates work and what the stages of the sleep cycle are, it’s time to discuss some of the ways we can seek to improve our sleep efficiency.

Create a Healthy Sleeping Environment

Attempting to fall asleep in an unhealthy sleeping environment is a recipe for disaster. If the lights are shining, music is playing, or your phone is within reach, chances are your sleep efficiency rate will decline as you lay in bed without truly falling asleep. This is when sleep deprivation can take hold if you’re not careful, as nights lying awake in bed will stop you from getting the amount of sleep you need.

To combat these potential negative distractions, turn the lights out and ensure the room is completely dark, thus creating an environment suitable for proper sleep. Cover or remove any lights that blink, flash, or interrupt your nightly routine. From there, leave your phone in a separate room — phone screens have a tendency to produce stimulating brain waves that can keep you awake, along with sounds and tones that act as triggering mental alarms. Be sure your bed and your bedroom are spaces free from sleeping distractions so you can spend your total time sleeping in a space devoted solely to sleep.

Follow a Sleep Schedule

While our day-to-day schedules may change, it’s important to maintain the “internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours,” as noted by Sparta Science We refer to this internal process as our circadian rhythm. Try to follow this rhythm naturally by following the same sleep patterns every single night.

Practice the same healthy habits before bed that prepare your mind for sleep, such as reading a book or drinking water, and go to bed at the same time each night if possible. Try to wake up at the same time each morning as well. Following a sleep schedule can lead to increased sleep efficiency rates and an increased sense of well-being as the body grows acclimated to sleeping and waking at specific times. Though you may not know it, your body benefits greatly from this sense of routine.

Consult a Sleep Specialist

While we’d all like to fall asleep quickly and stay asleep throughout the night, some of us simply aren’t capable of doing so. Conditions that include sleep apnea, insomnia, and even narcolepsy are all common roadblocks to a healthy night’s sleep.

If you think you may have one of these conditions, seek help from a sleep specialist. For instance, those suffering from insomnia would benefit from undergoing cognitive behavioral therapy for insomnia, or CBTI. Others may need medication, or they may be able to solve their problem with something as simple as a new mattress.

If you find yourself repeatedly struggling to attain a healthy night’s sleep or if your sleep efficiency rates are consistently low, consider reaching out to a healthcare professional who can lend a hand.

Take a Few Extra Steps for Better Sleep

While creating a healthy sleeping environment, sticking to a sleep schedule, and even consulting a specialist are some of the most important ways we can improve sleep efficiency, there are a few extra steps we can take along the way.

For instance, consider creating a sleep diary that you contribute to each morning after waking up. Take time to log how your sleep felt throughout the night, what worked to help you fall asleep, what posed a distraction, and what you can do to ensure you either maintain or create sleep patterns that will contribute to better sleep efficiency rates in the future.

You can also use one of the many apps designed to help you log and track your sleep over days, months, or even years. In these apps you can document when you notice sleepiness during the day, how your sleep felt, and with the help of a sleep tracker, even the total time of actual sleep versus time spent awake in bed. From there you can fine-tune your habits and achieve the best possible rates of sleep efficiency.

We All Need Sleep

Sleep is one of the most underrated yet important things we can focus on to ensure we’re maintaining our personal health. By calculating our sleep efficiency and improving upon that figure if need be, we’re providing our body with the care it craves and deserves.

If your sleep efficiency rating is low, use the tactics listed above to make improvements. And if need be, don’t hesitate to reach out to a specialist for help. While each of us may sleep differently, it remains something we all need, every day.

It seems that each week there is new technology being released that allows individuals to access even more data related to their fitness.

From watches that track your movement based on satellite positioning, to cell phones that are able to read a person’s heart rate just by the touch of a finger, there is no piece of information that goes unturned. Finding a fitness tracker isn’t the problem, sometimes the hard part is determining what readings are beneficial are which are not. Helping to narrow in on biometrics that are conducive to your specific fitness goals can help save not only money, but the headache of figuring out the functions of your tracker. One of the more up and coming fitness tracking devices are Pulse Oximeters. This relatively new (to the fitness/health sector) fitness trackers brings up these similar types of questions: what are Pulse Oximeters, and is this something that will help increase my fitness, or bring me closer to attaining my fitness goals?

SpO2

By definition, SpO2 is a measurement of the peripheral capillary oxygen saturation. Peripheral is pertaining to our bodies veins and arteries. This measurement is an estimate of the amount of oxygen in our blood expressed as a percentage of the amount of oxygenated hemoglobin to total hemoglobin. Hemoglobin is the protein that carries oxygen in the blood. Most people have heard of hemoglobin in relation to the blood disorder, anemia.

Effects of Low Oxygen Saturation:

When you body’s oxygen saturation percentage dips below 95%, you will begin to experience the effects of hypoxemia. Hypoxemia means that there is a low amount of oxygen in the blood; this leads to hypoxia, or low oxygen in the tissues. These conditions can lead to a person experiencing shortness of breath, headaches, fainting, and even confusion.

How SpO2 is Measured:

Pulse Oximetry is used to measure the blood’s oxygen saturation. This technique of measurement is a non-invasive calculation of the peripheral oxygen saturation. This technique also provides a measure of the individual’s cardio-respiratory function. Pulse Oximetry used to be used in only clinical practice for patients. Now biometric tracking devices are using it with a target audience of the fitness and sports performance populations. Pulse oximeters are useful in the hospital setting, but who really benefits from them in fitness applications?

Applications of Pulse Oximetry Measurement in Fitness:

While Pulse Oximetry may not have many applications in the general fitness population, it can have useful application in sport specific situations. These types of situations include when people are working out at levels hovering below, at, or above their VO2 max. Measuring your SpO2 can be beneficial during these specific workouts to show athletes and their coaches a specific work rate an athlete can sustain before their bodies begin to require more oxygen than is being produced. When individuals are able to look back at their data after a workout, they will be able to see the trend lines of their oxygen saturation percentage dropping. When the oxygen percentage begins to show a declining trend, this means that you are working above your body’s limit.

How can this be applicable? When knowing your body’s’ limits, you can tailor workouts to increasing your body’s VO2 Max by “pushing” your own limits.

For example, a cyclist could ride multiple two minute intervals increasing their power until they hit a point when their oxygen saturation begins to drop. This application does not only apply to cyclists alone, but many different disciplines of sport across the board that require an athlete to hit high, sustainable limits for a certain length of time; runners, cross country skiing, and swimmers are a few examples.

Another application for using pulse oximetry can be in high altitude events. People who partake in high altitude climbing can use SpO2 biometrics to help track their bodies limits and oxygen levels. A climber can use this measurement to also help them moderate their effort levels during an ascent. If they saw that during a certain part of their effort, ie: increasing altitude, that the oxygen percentage is decreasing; they could determine if that specific workload was in a sustainable range. If their O2 saturation levels were decreasing this can help them to reevaluate their effort. It may mean decreasing their rate of ascension or that continuing the climb may not be in the best interest of their body’s health.

Data is constantly evolving in the fitness industry and the ability to produce marginal improvements is constantly being tested. The  fairly new market of Pulse Oximeters for gathering fitness data is just one of the many new products to be introduced. There are clinical and sport specific applications where it’s information proves beneficial. Determining if you are part of this population of individuals can help you determine if investing in the measurement of your oxygen saturation is necessary.

When we think of “working out” typically we think of going to a gym, or at least of lifting weights. This can be true, but not all the time. A workout can be achieved anywhere with practically anything, including: your very own bodyweight! This is where incorporating calisthenic routines into your workout plan may be appealing since you can do these workouts from the comfort of your own home. No gym, or gym equipment required. First things first; what even are calisthenics?

Any exercise that does not involve the use of added weight, and solely body weight is considered to be a “calisthenic” exercise. In a world today filled with crossfit, bodybuilding, and olympic lifting it may not seem like calisthenics may be receiving the limelight, and this is true. Many of the popular workout routines of today are not focused around solely using bodyweight. Does mean they are bad? No! They are just targeting a different form of exercise and a different exercise response. Does this mean they are the best? Not exactly. Again, it depends on what the individual is looking to achieve through a workout. If you are looking to try to bench press 2 times your bodyweight, then hitting the weight room is a great idea. If you are looking for a great workout that’s quick and easy to do, then maybe calisthenics is the right choice for you! Calisthenics can be beneficial in a variety of ways, extending beyond the benefit of being able to perform them anywhere. They can help you to improve flexibility, muscular endurance, and strength.

Benefits of Calisthenic Exercises:

Calisthenics are known as one of the oldest forms of training. They attract many people due to simply the ease of working out anywhere with no equipment needed. Below are a few additional reasons why calisthenics may be the newest addition to your fitness training.

Endurance:

Performing a calisthenic workout in the form of a circuit is a great way to build muscular endurance. Performing a circuit 3-5 times through with limited rest will build up your body’s resistance to fatigue, kind of like a cardiovascular exercise. Continuing to perform these types of circuits with days of rest between can challenge your body to be able to handle more rounds of repetition prior to muscular exhaustion. Implementing a routine that works the entire body can help to build a muscular endurance for all of your muscle groups, including your cardiovascular system.

Flexibility:

A lot of the movements incorporated into a calisthenic workout requires some degree of flexibility. Take for example: the lunge. To perform this exercise, your body needs movement throughout the hip to allow for the hip extension of the leg placed behind the body. You can even experience tightness through quads and hamstrings. Tightness that you may not even know of, will become evident through the addition of calisthenics to your training. Through increasing strength, your body will become adapted to increasing its flexibility to perform the movements correctly. Having proper range of motion, allows your body to utilize the correct muscle groups to perform an exercise. Inhibited muscles due to poor flexibility can develop incorrect muscle patterns! That being said, standard stretching should not be overlooked. It should be encouraged to perform dynamic stretching prior to calisthenic workouts.

Strength:

This may seem like common sense that calisthenics would build strength, but it doesn’t just apply to muscular strength! Bodyweight exercises can also help to improve bone and joint strength as well. The US Military implements the use of calisthenics in their basic training to help build strength, but to also avoid injuries. Adding calisthenics also helps to build your muscular strength without the wear and tear that weightlifting can have on your body.

Upper Body Exercises:

Some of the most commonly known exercises for your upper body include: push ups and pull ups. Though these are well known, there are various forms of these exercises that you can incorporate into a circuit. Push ups work your chest, shoulders, and tricep muscles directly. Doing various forms such as: T-Push ups, Single Arm Raise, Shoulder Tap, or Clap Push ups. These various forms can help incorporate additional muscle groups such as your abdominals. Pulls ups also help to strengthen your posterior chain (back muscles.) They also help to improve your hand grip. You can vary this exercise by either widening or narrowing your grip.  Additional forms of exercises can include: planking, inclined push-ups, and tricep dips.

Lower Body Exercises:

As the push up is famously known for an upper body exercise, the squat would be the equivalent in lower body exercises. Prior to performing a squat, it is also best to ensure that you have proper muscle activation in your glutes! Performing a few bridges can help to get your glutes firing. It is also best to squat within your range and try not to push outside your limits. Performing squats can also be doing in various forms. From a standard double leg squat, to single leg squatting with stability challenges. Adding in single leg squats can help test your coordination as well as strengthen and develop lower leg muscular function and activation. Another well known lower body calisthenic would be the lunge! This exercise can help develop strength in the quads as well as the glutes!

The gym is always a great place to increase your fitness, but don’t let it confine you. Fitness and strength can be achieved anywhere and that statement has never been made more true than through the use of Calisthenics. Not only strength building, calisthenics can help increase your cardiovascular fitness as well. Finding a calisthenic routine that works for you can help develop increased strength, flexibility, and stamina.

Of the many fluids that play an important role in the human body, none compare to the fluid that is most abundant: blood.

As a vital substance that circulates throughout the entire body, blood serves three primary functions that all contribute to personal health: transportation, protection, and regulation. Yet of the many roles that blood can fill, perhaps it’s most important role is to transport oxygen to your cells while removing carbon dioxide, which is considered waste, to be released through the lungs upon exhale.

Maintaining those oxygen levels within the blood is no easy task. If low blood oxygen levels are present, problems can arise that spell impending health complications or even death.

High blood oxygen levels, on the other hand, are rare and often only occur when using supplemental oxygen. A harmful outcome that may transpire as a result of elevated blood oxygen levels (hyperoxia) is central nervous system toxicity — a condition in which seizures, disorientation, respiratory problems, and even death can occur.

While most children and healthy adults don’t need to monitor their blood oxygen level, those with chronic health conditions such as asthma, chronic obstructive pulmonary disease (COPD), and heart disease must do so on a regular basis.

Here we’ll break down the basics of blood oxygen levels, discuss how they’re measured, and give you a better understanding of the benefits of knowing your blood oxygen saturation levels.

What Is the Blood Oxygen Level?

Blood is composed of three primary ingredients that all contribute to its various responsibilities throughout the body. These three ingredients include a liquid substance referred to as plasma, and solids referred to as white blood cells and red blood cells.

Plasma is the most abundant substance in our blood (over 50% of blood is composed of plasma), which is made up of water, salts, and proteins. White blood cells are the cells of the immune system that protect the body against infection and disease. And red blood cells are the cells that carry oxygen throughout the body.

Given this information, blood oxygen level is simply a measure of how much oxygen is being carried by red blood cells in the body. The body will closely monitor blood oxygen levels to keep them within a specific range, ensuring that every single cell receives the oxygen it requires to function properly. This information is measured in millimeters of mercury, or mm Hg for short.

Now that we know what our blood oxygen level is, let’s discuss how it’s properly measured with the technology we have available today.

How Is Blood Oxygen Level Measured?

Of the two different ways that we can measure and monitor blood oxygen levels, the most efficient way is by an arterial blood gas, or ABG for short. To perform this test, a certified phlebotomist or licensed practitioner takes a blood sample from an artery in the body (often times the radial artery in the wrist) because unlike veins, which carry deoxygenated blood, arteries only carry oxygenated blood to cells.

The sample of blood acquired by the healthcare provider undergoes processing to determine levels of oxygen and carbon dioxide in the body. Though this process is efficient and accurate, it is also invasive and potentially painful, making it a less common choice compared to using a pulse oximeter.

A pulse oximeter, or pulse ox, is a small device that attaches to the fingertip and sends a beam of infrared light into the capillaries beneath the skin. From there, it measures how much light is reflected off the gases in the blood and provides a reading that accurately estimates what percentage of the blood is saturated with oxygen.

This measurement is often referred to simply as SpO2. While using pulse oximetry is slightly less accurate, it is extremely easy and non-invasive, making it the go-to measurement option amongst medical institutions around the world.

Unlike measuring ABG through a major artery, a pulse oximeter can be attached to the fingertip, toe, or earlobe with ease. Such equipment is often for sale through local pharmacy chain stores, so patients can even monitor their blood oxygen level at home. And while research once suggested that nail polish or acrylic nails could affect a pulse oximeter reading, new research now suggests otherwise.

High, Normal, and Low Blood Oxygen Levels

A measurement of oxygen levels in the blood is called oxygen saturation. Use the guidelines below to help understand what an oxygen saturation reading might mean.

High Blood Oxygen Levels

It is uncommon for oxygen saturation levels to be high if breathing is unassisted. That being said, supplemental oxygen may be required to heighten oxygen levels or bring them back to normal under certain conditions.

For instance, mountaineers who experience high altitudes may not receive enough oxygen from the surrounding air (this is because oxygen concentration levels in the atmosphere decrease as altitude increases). Alternatively, medical conditions may impair the amount of oxygen one can absorb into the blood.

In both cases, supplemental oxygen may be utilized to maintain healthy oxygen levels in the blood, and that supplemental oxygen can lead to high blood oxygen levels. As we mentioned above, excessive and consistent high levels of oxygen in the blood may lead to complications as a result of oxygen poisoning.

Normal Blood Oxygen Levels

Normal blood oxygen levels will fall between 80 and 100 mm Hg (millimeters of Mercury). And if a pulse oximeter is used to measure blood oxygen levels, a normal reading will fall between 95-100% saturation.

Low Blood Oxygen Levels

A reading below 80 mm Hg or 95% saturation is considered low, and we refer to this abnormally low concentration of oxygen in the blood as hypoxemia. Such low levels may be the result of a lung disease such as severe COPD that inhibits oxygen flow, or it could indicate there is carbon monoxide in the air, which the body will mistakenly use to replace oxygen.

To determine what factors are causing low blood oxygen levels, speak to a healthcare provider. Low blood oxygen levels can be an indication of serious complications within the body, and should therefore be addressed as soon as possible after detection.

Symptoms of Low Blood Oxygen Levels

Many symptoms may arise as a result of low oxygen levels in the blood. These include:

• Shortness of breath
• Confusion
• Chest pain
• Nausea
• Dizziness
• Increased heart rate during simple activities or during sleep
• Visual disorders
• Lack of coordination
• Increased pulse rate
• Low blood pressure

Causes of Low Blood Oxygen Levels

Hypoxemia, or low oxygen blood levels, may be caused by the following primary complications. Additionally, medical conditions or environmental factors can contribute to the primary causes listed below.

• A low level of oxygen concentration in the air like you would experience at high altitude
• Poor lung conditions that cause a failure to inhale fully and send oxygen to cells and tissues, frequently caused by pneumonia, COPD, acute respiratory distress syndrome (ARDS), or sleep apnea
• Inability of the circulatory system to send blood through the lungs where it can collect oxygen, frequently associated with anemia, heart disease, certain medications

Treatment for Low Blood Oxygen

Treatment for low oxygen levels involves receiving supplemental oxygen to maintain normal oxygen levels. This form of intervention can be performed at home and is referred to as home oxygen therapy, or HOT for short.

Home supplemental oxygen is considered a medication and must, therefore, be prescribed by a doctor. As always, be sure to follow medical advice and consult a medical professional before utilizing any treatment options.

Additionally, lifestyle changes may positively benefit oxygen levels if levels happen to be low. For instance, consistent exercise and a healthy diet play an integral role in combating heart disease, which in-turn affects oxygen saturation levels in the body.

Monitoring Your Blood Oxygen Levels

While most people don’t need to monitor their blood oxygen saturation levels, those with health problems that cause low states of oxygen saturation would be wise to check their levels consistently. Doing so only requires a pulse oximeter, which can often be purchased at the nearest drug store.

Combating low oxygen levels through lifestyle changes, like adopting a healthier diet, starting a new exercise routine, or understanding your sleep habits can take to improve quality of life. When the lungs are happy and oxygen can circulate throughout the body, countless health benefits are in store.

Rarely does one explore the world of physical fitness and exercise training without hearing the puzzling phrase “VO2 max.” Utilized by both professional athletes and casual competitors alike, VO2 max is believed to be one of the greatest indicators of an individual’s endurance.

But what exactly is it? And if elevated levels of it lead to a higher quality of life, how can we increase it? Here we break down everything you need to know about VO2 max, including how you can calculate it for yourself, what modifies it, and why it truly matters.

What Is VO2 Max?

The human body is composed of eleven complex and rather important systems, each one specifically designed to accomplish a different task.

The muscular system generates force that transforms into motion. The skeletal system acts as a framework to provide support, movement, and protection. And perhaps most importantly, the respiratory system fuels muscles with help from the circulatory system. These two work in tandem to pump oxygen-rich blood throughout the body, fueling all other systems in the process.

When we choose to exercise, the task of pumping oxygen-rich blood while removing carbon dioxide is referred to as cardiorespiratory endurance. It’s “the level at which your heart, lungs, and muscles work together when you’re exercising for an extended period of time.” And because cardiorespiratory endurance is determined by oxygen consumption, we refer to this commonly as VO2, or the maximum volume of oxygen that’s used by the body.

VO2 max, however, is a bit different from the standard VO2. Instead, it’s considered to be how fast your body can consume oxygen when you’re exerting yourself at your maximum rate, or your peak aerobic capacity. It’s measured in milliliters of oxygen used per minute per kilogram of body weight (mL/kg/min).

How Do You Calculate VO2 Max?

For professional endurance athletes like cyclists or skiers, calculating VO2 max requires sophisticated equipment and heavily monitored research environments. A standard test involves breathing oxygen via a mask while undergoing a treadmill test at a specific pace.

The pace grows more difficult as the fitness test progresses, and the participant must therefore consume a greater amount of oxygen to power the body’s muscles. Over the course of the study, the athlete’s highest VO2 max is determined, often when they’ve sustained their max heart rate for a brief period of time.

This testing can be expensive, however, and is, therefore, not suitable for everyone. As a result, physiologists have designed specific formulas that allow anyone to calculate their VO2 max at home. Doing so takes into account factors that include age, resting heart rate, and maximum heart rate. An alternative formula may look something like this:

VO2 max = 15.3 × (MHR ÷ RHR)

In this formula, MHR is your maximum heart rate, and RHR is your resting heart rate.

Though your VO2 max will be partially determined by your age and aerobic endurance, most individuals can expect their values to land within a certain range based on their age group.

For instance, sedentary men between the ages of 18-25 years can anticipate levels of 30-36 mL/kg/min. Women of the same age and physical ability can expect levels of 28-32 mL/kg/min. Meanwhile, an elite endurance athlete will often see higher VO2 max figures, often surpassing 60 mL/kg/min. But as has always been the case, this figure has a habit of declining steadily with age.

What Determines VO2 Max?

Age and heart rate are not the only factors that play a role in determining your VO2 max. Because aerobic activity is regulated by your heart’s ability to pump oxygen-rich blood to the body, the heart’s size and strength is a key component. The lungs, meanwhile, must be capable of consuming vast quantities of oxygen that diffuses into the bloodstream. A strong set of lungs will make aerobic exercise less demanding, and your VO2 max will increase as a result.

Truth be told, factors that range from cardiovascular fitness to personal training to your body’s innate ability to diffuse oxygen all play a role in governing the maximum amount of oxygen that one can consume. As a result, professional athletes are constantly pushing the limits of training to amplify their max level, utilizing exercise tests, training plans, and fitness trackers whenever possible.

Why Is VO2 Max Important?

So if VO2 max is a number that constantly shifts and changes based on a multitude of factors, why is it so important in the first place?

Simply put, VO2 max has long been considered the primary indicator of how good you’ll be at aerobic exercise, fitness, and overall physical performance. However, as science has advanced, so too has our understanding of the benefits that come from an increased VO2 max level.

Research continues to indicate that low aerobic fitness levels are connected to an increased risk of death from a litany of causes, though cardiovascular disease remains the largest threat. Therefore, higher aerobic fitness levels are associated with numerous health benefits, such as a longer lifespan, reduced risk of stroke, heart disease, diabetes, and cancer, plus improved mood, improved sleep patterns, and an overall better quality of life.

How to Increase Your VO2 Max

Perhaps the one question people most often ask after learning about VO2 max and its benefits is how they can increase it. The most effective method we utilize to accomplish this task is referred to as High Intensity Interval Training, or HIIT for short.

This form of training places an increased demand on maximal oxygen uptake as a means of producing a higher max level. Because HIIT workouts require the body to deliver a greater volume of oxygen due to increased demands from exercise, how much oxygen is consumed relates directly to what the body can achieve.

Common HIIT plans begin with a steady warm-up followed by intense bouts of cardio with a high demand placed on exercise intensity. These bouts of cardio may include intermittent sprints, hill climbs, and various other tasks that incorporate long intervals. When the workout is complete, a cool down often takes place to reduce lactic acid buildup in the muscle, which has long been known as the cause of muscle soreness. Individuals that utilize this form of training can expect their VO2 max score to increase steadily over time.

If HIIT workouts sound too daunting, however, regular exercise that increases heart rate and blood volume can be just as effective. The key is simply to maintain these bouts of exercise over long periods of time. But the more fit an individual becomes, the more difficult it becomes for them to increase their VO2 max.

Increasing VO2 Max for a Healthier Life

While VO2 max may seem like a figure used solely by professional endurance athletes, in reality, it serves us in many other ways. Used not only as a predictor of overall performance, it’s also an indicator of one’s overall health and can even be utilized as a tool to help predict health risks to come.

This seemingly simple number has changed the manner by which we assess one’s aerobic abilities as research continues to push our understanding of what maximal oxygen consumption truly means.

As with most exercise-related statistics, however, your VO2 max is only as important as the physical work you perform to increase it. Following general exercise guidelines or personalized exercise prescriptions will alter your max level over time, and in turn, lead to a better overall quality of life. As it turns out, VO2 max is far more than just another number.

If you’re interested in fitness and nutrition, you’ve likely heard the term macronutrients, aka macros. It seems everyone is concerned about counting macros and calculating their daily intake. So what are macronutrients? Macros are the fundamental nutritional compounds your body needs to function: protein, carbohydrates, and fats.

While some macronutrients get a bad reputation (looking at you, carbs), the truth is that they’re all essential for mental and physical functioning. Depriving your body of any one macronutrient can greatly reduce your performance both in your fitness routine and in everyday life.

Plus, understanding the unique roles of carbohydrates, proteins, and fats in the body can help you better understand and meet your nutritional needs. Here’s what macronutrients are, and how you can fuel your body properly with each one.

What Are Macronutrients?

Humans need large amounts of macronutrients in order to survive. This is because they provide energy, which the body needs to perform life-sustaining tasks like circulation, hormone production, energy synthesis, and digestion.

The energy provided by macronutrients is measured in calories. This is in contrast to micronutrients, which are vitamins and minerals obtained from food.

So how many calories do macronutrients offer? Carbohydrates and protein contribute four calories per gram. This means that one gram of protein equates to four calories. Fats contribute nine calories per gram.

Each type of macronutrient should be consumed in balance, according to your specific needs.

Age, gender, and physical activity level all influence how many macronutrients you need per day.

Counting Calories vs. Macronutrients

The traditional method of losing weight has been to count calories and reduce overall intake of fats and carbohydrates. This makes sense: when calorie intake is lower than calories expended, the body burns fat and weight is lost.

However, counting calories doesn’t account much for the nutritional value of food. For example, a cookie may contain the same amount of calories as a salad, but the macro content of the salad would likely be much healthier because it provides essential fats and proteins.

More and more, people are counting macronutrients to lose weight while still fueling the body properly. The IIFYM (If It Fits Your Macros) diet is one regimen that focuses on macronutrients instead of calories.

Founded by Anthony Collova, IIFYM helps people calculate the number of calories from protein, carbs, and fats they need to lose weight. These calculations are based on basal metabolic rate, activity level, and weight goals. Then, a plan is created to determine a macro limit and meet that limit daily. Here’s a look at each how each macronutrient works in the body.

Carbohydrates

Carbohydrates are the primary source of energy in the human body. They provide at least 50% of total calories per day. The two main types of carbohydrates are simple and complex.

Simple carbohydrates are composed of small molecules like monosaccharides and disaccharides, which increase blood sugar quickly. In contrast, complex carbohydrates like starches and fiber increase blood glucose levels slowly over time.

Many people tend to look to low-carb diets to lose weight, but most nutritionists stress the importance of including some healthy carbohydrate sources in the diet. When counting macros in your diet, it’s best to reach for complex carbohydrates instead of simple carbohydrates. These keep you fuller for longer, which reduces instances of excess hunger (which leads to calorie consumption and weight gain).

Proteins

Protein is made up of amino acids, which help build muscle, transport nutrients, and prevent illness, among many other functions. The body requires 20 different amino acids for optimal functioning, 11 of which are created by the body. The other 9 must be obtained through protein sources in food, including meat, dairy, soy, and grains.

Essential amino acids include lysine, tryptophan, phenylalanine, leucine, isoleucine, valine, methionine, threonine and histidine. Ample protein can be found in both animal and plant products, and eating a varied diet can ensure that you get all the required amino acids. This is important to understand because it’s a common misconception that animal sources are the only protein providers.

In fact, high-protein plant foods include seeds, quinoa, beets, avocado, and raw greens. Legumes such as lentils, chickpeas, and black beans are great sources of protein as well. Enough protein can be obtained from a vegetarian or even vegan diet as long as you follow a healthy and macronutrient-dense regimen.

Fats

Fats are considered macronutrients because they’re vital for maintaining cell function, boosting brain development, protecting the organs, and boosting nutritional intake from other foods. Fats are composed of fatty acids and glycerol. Essential fatty acids include linoleic acid, an omega-6 fatty acid, and a-Linoleic acid, an omega-3 fatty acid. These are both considered essential because humans can’t synthesize them naturally, meaning they must be obtained from food.

According to the Linus Pauling Institute at Oregon State, “Both omega-6 and omega-3 fatty acids are important structural components of cell membranes, serve as precursors to bioactive lipid mediators, and provide a source of energy.” And both are available from fat as the macronutrient.

Understanding Types of Fats

You’ve probably heard about healthy fats vs. unhealthy fats, the latter of which are found mostly in animal products and processed foods. Eating fat doesn’t always translate to increasing your body fat, however.

Rather, it’s important to understand that unhealthy fats are trans fats, which can lead to weight gain when consumed in large quantities. Consuming too many grams of unhealthy fat per day can also affect a person’s long-term health — increasing the risk of heart disease and stroke while reducing immune system functioning.

What about a low-fat diet? Since 20% of your diet should be comprised of healthy fats, a low-fat diet may not allow for the ample amount of healthy fats required. Focusing only on low-fat foods may also not allow for enough consumption of healthy foods.

Even if you do follow a low-fat diet, it’s important to obtain most of your fats from lean, unsaturated sources. Examples include avocados, almonds, walnuts, and seeds. Oils are also a source of healthy fats, and vegetable oils like olive oil and coconut oil can be incorporated into cooking to boost healthy fat intake and support weight loss.

Understanding Macronutrients and Making Healthy Food Choices

Macronutrients are the building blocks of the human diet. Carbohydrates, protein, and fats are all considered essential because they keep our body healthy and functioning properly.

Carbohydrates work to provide us with energy, so we can fuel bodily systems like digestion and hormone production. Proteins also give us energy, and they help us manage the repair and growth of tissue so we can continue to perform at optimum levels. Fats, though often associated with negative implications, are essential for both our brain and organs.

Counting macronutrients instead of calories may be a smarter way to stay on top of your nutrition and maintain a healthy weight. By making macronutrient-rich food choices, you can better energize your body and ward of instances of deficiency and disease.

For some people, getting a good night’s sleep is as simple as cozying up in bed and closing their eyes. For others, restful sleep can be elusive. Poor sleep can be the result of a sleep disorder like sleep apnea or of behaviors  like drinking coffee or alcohol before bed. Whatever the cause, it can be frustrating when you can’t fall asleep or consistently wake up exhausted and hitting the snooze button.

For people who have difficulty sleeping, it’s important to make lifestyle changes that help promote better sleep. Exercise is a common recommendation for people who suffer from poor sleep. However, some argue that exercise timing is important and that working out before bed may actually lead to worse sleep. We’ll go over whether working out before bed leads to poor sleep and give you advice on the best times to get active.

Does Working Out Before Bed Lead to Worse Sleep?

When we exercise, our bodies work harder and require more oxygen and energy to function at these higher intensities. As a result, our heart rates increase and our bodies increase adrenaline levels, which can make us feel wired. These effects are among the many reasons we exercise. High-intensity workouts such as HIIT (high-intensity interval training), cardio, and powerlifting help support weight loss, burn fat, and give us an energy boost.

But when it’s bedtime, we want to feel relaxed and sleepy. Logical reasoning would suggest that exercise before bed would make sleep worse, but it’s a bit more complicated than that. It’s true that some people suffer from poor sleep when working out before bed. These people tend to feel wired after exercising and have difficulty relaxing and getting restful shut-eye.

For the majority of exercisers, however, research indicates that working out before bed isn’t harmful to sleep. A 2011 study found that vigorous late-night exercise did not lead to decreased sleep quality. They did identify an increase in heart rate during the first few sleep hours, though this did not seem to affect overall sleep quality.

The National Sleep Foundation conducted a 2013 Exercise and Sleep Poll where 1,000 participants were analyzed for sleep quality and exercise. The poll found that, compared to people who didn’t exercise at all, 83% of the study participants reported improved sleep when they exercised at any time of the day. The study found no difference in sleep quality for participants who exercised right before bed.

New studies indicate that exercise can improve sleep for most individuals and particularly for people who suffer from insomnia. A meta-analysis published in 2018 by PeerJ examined nine studies and found that exercise improved sleep quality without adverse side effects. Participants reported decreased problems with daytime impairment and sleep disruptions.

If you’re someone who finds themselves wired after working out late at night, move your exercises earlier if possible. But for the majority of the population, research indicates that working out before bed isn’t detrimental to sleep.

If you’re worried about getting good quality sleep, start by monitoring your sleep habits with a wearable tracker like Biostrap. It’s also a good idea to talk with a qualified healthcare professional or a sleep medicine expert. A medical professional can help you understand your sleep situation and offer tips on how to get a better night’s rest. They may also provide information on the best times to workout to support your sleep.

The Best Times to Workout

Whether you find that late-night workouts interfere with getting ZZZs or you simply want to avoid issues with sleep when exercising, there are other times of day when you can get moving. Here are some of the best times you can exercise to support overall health and improve sleep.

Morning Workouts

It can be hard to wake up early and hit the gym or the trails, especially if you have to get your household out the door or head to work. However, getting up just a little earlier to fit in a workout can offer significant rewards. First off, people who opt for morning workouts tend to be more consistent. You’re less likely to forgo a workout first thing in the morning compared to the afternoon when your day has gotten busier.

Waking up early and at the same time also helps to regulate your body’s natural sleep/wake cycle, known as the circadian rhythm. This neurological process helps send signals to your body about when it’s time to be alert and when it’s time to wind down for sleep. By waking up early, your body will get into a natural rhythm of sleeping and waking, improving sleep overall.

Afternoon or Lunch Workouts

For people whose mornings are already chaotic, early workouts may not be the best choice. Instead, try working in an exercise routine during your lunch break or in the late afternoon. You’ll still have several hours before bedtime so you won’t disrupt sleep even if you tend to feel wired after working out.

As you workout, your body temperature increases, signaling your system to stay awake and alert. As a result, afternoon workouts can give you an energy boost that helps you power through the afternoon. Plus, the core body temperature begins to fall again around four to five hours after a workout, helping to signal your brain that it’s time for sleep.

Anytime

The bottom line is, regular exercise has been linked to better sleep in general. That means any exercise is better than no exercise at all. If the only time you can fit exercise in is in the evenings, that’s ok.

For nighttime workouts, try to focus on less strenuous exercises that don’t get your blood pumping as intensely as cardio. Instead, try incorporating a walk into your evening routine, lift a few weights for strength training, or do a calmer activity such as yoga or pilates.

The time of day that you should exercise is really based on your specific sleep needs. Some people will find they need to do early morning workouts to maximize deep sleep while others don’t have adverse effects from nighttime workouts.

Sleep is a complicated process involving multiple physiological and psychological components so there isn’t one specific workout time that works for everyone. To identify the best time to workout and track how it affects your sleep, a wearable tracker device can help.

Monitor Sleep and Workouts With Biostrap

Biostrap is a wearable tracker that enables you to track heart rate variability and oxygen saturation levels, and offers physical activity classification capabilities to help you get the most out of your workouts. With this data, you can monitor your metrics and build workouts to help you achieve your fitness goals.

The wearable also features a comprehensive sleep lab tool that captures biometric readings every two minutes. You’ll get in-depth information on arm and leg movements, snoring, and other sleep disturbances so you can adjust your habits to improve sleep. You can even print out your sleep lab report to bring along to your doctor if you’re looking for new ways to improve your workout schedule, address sleep problems, and get a good night’s sleep.
