Ever feel like your body’s sending you mixed signals? One moment you’re wound up tighter than a spring, and the next, you’re too drained to move. It’s like being stuck in traffic with your emotions honking loudly, trying to signal you through the fog. Understanding whether you’re dealing with emotional or physical stress isn’t just about putting a name to your pain; it’s about finding the right tools in your self-care kit to deal with it. Distinguishing between these two types of stress is crucial in order to manage them effectively.

Emotional or physical stress

Picture this: Emotional stress is like having a bunch of browser tabs open in your brain—constantly loading, never quite settling. It stems from worries, anxieties, and the mental burdens we carry. Physical stress, on the other hand, is the body’s way of saying, “Hey, remember that high-intensity interval training session at the gym? I’m still dealing with that.”

Why does the distinction matter? Because the remedy for a mind cluttered with worries is different from the cure for muscles aching from overexertion. Recognizing the source of your stress is step one on the path to managing it.

How to tell them apart

Feeling stuck in a mental loop, ruminating over past conversations or future anxieties? That’s your cue for emotional stress. On the flip side, if your body feels like it’s been through a wringer after a physically demanding day, you’re looking at physical stress. The key to differentiation lies in self-awareness—listening to what your body and mind are telling you. Here’re are six actionable tips for managing stress – both physical and emotional.

Caught in a thought tornado? Go for a walk.

When your mind is a maze of worries, a change of scenery can work wonders. Walking isn’t just good for your body; it’s a balm for the mind, too. It’s about hitting the refresh button on your thoughts and letting nature’s calm infiltrate your mental chaos.

Feeling down? Hit the gym.

If emotional stress has you feeling low, exercise can be your elevator. It’s not just about staying fit; it’s about releasing endorphins, those feel-good hormones that act like natural painkillers and mood lifters. Whether it’s a dance class, a quick jog, or yoga, moving your body can help clear the emotional clutter.

In a Funk? Get some sun.

Never underestimate the power of a sunny day. Sunlight is nature’s mood enhancer, boosting your serotonin levels and battling the blues. So, if you’re feeling down, step outside and let the sun’s rays lift your spirits. Even a brief lunch break under the sky can make a difference.

Muscles screaming after a workout? Prioritize recovery.

If physical stress has left your muscles shouting objections, it’s time to listen. Rest is not laziness; it’s an essential part of the recovery process. Combine it with strategies like a warm bath, sauna (if you can), gentle stretching, or massage, and you’re not just treating your body; you’re thanking it.

Overwhelmed by emotions? Write It down.

Sometimes, the act of transferring your thoughts from mind to paper can help untangle them. Journaling is a therapeutic way to face emotional stress head-on. It’s about giving your feelings a place to rest outside of your head.

Breathe through it: The power of mindful breathing.

Whether it’s emotional anxiety or the aftermath of a physical strain, mindful breathing can be a bridge to calm. Deep, deliberate breaths signal your body that it’s safe to relax, turning down the volume on stress.

Why it all matters

Understanding the nature of your stress is like having the right key for the lock. It empowers you to choose the most effective strategies for relief, ensuring that you’re not just throwing solutions at the problem and hoping something sticks. It’s about targeted, effective self-care that acknowledges the complexity of human experience—recognizing that we are both mind and body, intertwined.

Deciphering whether your stress is emotional or physical is more than a mental exercise; it’s a critical step toward holistic well-being. By tuning into the signals your body and mind are sending, you can tailor your self-care practices to meet your needs effectively. Whether it’s through movement, mindfulness, or simply soaking up some sun, the path to managing stress starts with understanding its roots. Remember, in the journey toward wellness, every step, every breath, and every moment of mindfulness counts.

In today’s fast-paced world, stress has become a pervasive problem that affects our physical and mental well-being. Chronic stress can have detrimental effects on our health, leading to various disorders and increasing the risk of cardiovascular problems and mental health issues. For effective stress monitoring and management, it is crucial to accurately measure its impact on our bodies.

Traditional methods of stress assessment, such as physical tests and questionnaires, have limitations in terms of subjectivity and accuracy.

However, advancements in wearable biosensors have paved the way for real-time, continuous monitoring of stress biomarkers, providing valuable insights for clinical diagnoses and personal stress management.

Unraveling the complexities of stress: a holistic approach

Stress, as an intricate and multifaceted physiological response to external demands, triggers the orchestrated release of cortisol, adrenaline, and noradrenaline – molecular protagonists underpinning the “fight-or-flight” reaction.

However, prolonged exposure to stress ushers in a cascade of physiological changes, resulting in disruptions to the harmonious equilibrium orchestrated by the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic adrenal medullary (SAM) axis. These disruptions contribute substantively to the pathogenesis of anxiety, depression, and cardiovascular morbidity.

Beyond traditional metrics: the futility of conventional stress assessment

Traditionally, stress has been measured through physical tests and questionnaires. The Trier Social Stress Test (TSST) is a commonly used test that assesses acute stress levels by subjecting individuals to public speaking and arithmetic tasks. Saliva, blood, psychophysiological, and cognitive measures are then analyzed to evaluate stress levels.

While these tests provide valuable information, they are not without limitations. Variability in test conditions and the subjective nature of self-reporting can impact the reliability and reproducibility of results.

Another widely used method is the Perceived Stress Scale (PSS), a survey that assesses an individual’s overall stress levels based on their perceived life experiences. Similarly, the Kessler Psychological Distress Scale (K10) measures mental distress levels. These tools provide insights into an individual’s subjective experience of stress but do not offer objective measures of physiological responses.

Wearable biosensors: a panacea for stress monitoring

Recent advancements in stress monitoring focus on the quantification of stress biomarkers, which are molecules or biometrics, or physiological indicators, that provide insight into an individual’s nervous system state. Biomarkers can be detected in various bodily fluids, such as blood, saliva, urine, and sweat. Sweat biomarkers, in particular, have gained attention due to the non-invasiveness and ease of collection.

Sweat contains a wide range of metabolites, electrolytes, and minerals that can serve as indicators of stress levels. Cortisol, a glucocorticoid hormone, is considered the gold standard for evaluating the activity of the HPA axis. Other stress biomarkers include epinephrine, norepinephrine, alpha-amylase, and interleukin-6. Electrochemical and colorimetric transduction methods have been developed to detect and quantify these biomarkers in sweat.

Additionally, the Biostrap Kairos, introduces a novel way to assessing autonomic nervous system balance including sympathetic and parasympathetic branch quantifications. Utilizing raw PPG, Kairos captures relevant biometrics including beat-to-beat heart rate data, heart rate variability (HRV) and respiratory rate to allow for in-depth objective data analysis.

Such real-time, seamless, and unobtrusive collection of stress data is highly valuable for simultaneously prioritizing user comfort and feasibility during diverse physiological parameters.

Challenges of sweat measurements

While sweat analysis have shown great potential in stress monitoring, there are still challenges to overcome. The correlation between sweat analyte (or chemical undergoing analysis) concentrations and blood concentrations is complex, and factors such as sweat rate and analyte distribution can affect the accuracy of measurements. Extracting interstitial fluid (ISF) analytes in a non-invasive manner also presents challenges, as extraction efficiency and skin surface contamination can impact accuracy.

Further research is needed to validate the clinical utility of sweat as a diagnostic biofluid for stress monitoring. Improvements in sampling methods and analyte monitoring techniques are necessary to enhance the reliability and accuracy of wearable stress sensors. Integration of multiple sensing arrays and the development of multiplexed wearable sensing platforms hold promise for comprehensive stress assessment.

Innovations toward a new trajectory

Advancements in wearable biosensors have revolutionized the field of stress monitoring. These devices provide real-time, continuous data on stress biomarkers, allowing for personalized stress management and clinical diagnoses. While sweat sensors offer a non-invasive and convenient method for stress assessment, there are challenges that are yet to be overcome.

By harnessing the power of wearable biosensors, like Biostrap Kairos, we can gain valuable insights into our stress levels in real time and any given time of the day and take proactive steps to improve the state of our nervous system.

Elite athletes use Heart Rate Variability (HRV), resting heart rate and other metrics to manage their training regimens and recovery time. Intense training stresses the muscles, hormones, heart and lungs. By tracking these biometrics, athletes optimize their mix of recovery time and training. They train smarter, not just harder. Exercise is a form of physical stress. Mental and emotional stress also affect your body.

Both mental and physical stress may disrupt homeostasis. This can lead to metabolism issues, insomnia, heart problems, hormonal imbalances, and chronic illness. Stress management and stress reduction improve both quality and quantity of life. You can use HRV and other key biometrics to track the success of your stress management program and to plan for “recovery” just like an elite athlete.

Before we discuss applications, it helps if you understand what these biometrics measure and how stress may alter these readings in the short and long term.

How Stress Affects Your Heart and Your Oxygen Levels

Heart Rate and Stress

Most health-conscious people recognize that stress impacts well-known metrics like heart rate and blood pressure. Have you ever found that your pulse and blood pressure were higher than normal at the dentist’s office? If so, you experienced this phenomenon.

Resting heart rate measures how fast your heart beats while you rest. Many people take a resting heart rate in the morning as a quick barometer to their cardiovascular health.  Your heart rate varies day to day, and moment to moment. The following factors may alter day-to-day resting heart rate:

  • Caffeine consumption
  • The previous day’s workout
  • Quality of sleep
  • Hydration levels
  • Hormone cycle fluctuations
  • A large meal or alcohol the night before
  • Stress levels

If you consistently follow a well-designed training plan you may find that your average resting heart rate decreases along with improvements in your physical fitness.

However, as a measure resting heart rate is limited. Due to genetics, some people just have faster resting heart rates than other people. Some hormone imbalances like low thyroid levels may decrease your average resting heart rate. Due to these reasons, you may benefit even more from tracking more sophisticated data points.

SPO2 and Stress

SpO2 stands for peripheral capillary oxygen saturation. It estimates how saturated your blood is with oxygen. A healthy, fit person usually sees a SpO2 between 95% – 100%. Illness, altitude, heart disease, smoke inhalation all affect SpO2.

Your SpO2 measure may not vary quite as much as your resting heart rate and HRV, but a sudden drop often indicates stress to your body. Traditionally athletes who train in higher elevations track SPO2 to help ensure they are getting enough oxygen. With the right device this is an easy metric to track along with resting pulse.

HRV and Stress

HRV measures time between your heart beats. When you are at an optimal state of rest and wellness, your heart is ready to respond to life’s demands. The space between heartbeats varies a little depending on your needs. When your system is “stressed,” your resting heart rate may appear the same, but there may be less variation between the heartbeats.

Tracking HRV informs you of subtle changes. For example, people sometimes find their HRV decreases a couple days before they notice cold or flu symptoms.

Factors that influence HRV include:

  • Quantity and quality of sleep
  • The previous day’s workout
  • Caffeine or alcohol consumption
  • Emotional and mental stress
  • Nutritional habits
  • Hormonal fluctuations
  • Illness or injury

Five Techniques To Use Biometrics in Your Stress Management Program

Take Baseline Readings

Take regular, ideally daily, readings since many factors affect biomarkers like HRV and resting heart rate. Try to take the measurements at a consistent time under similar conditions. For example, you may take your baseline reading shortly after you wake up, before you eat or drink anything, and while relaxing. A higher HRV reflects a more optimal state than a lower HRV reading. A lower resting heart rate or pulse also reflects a more relaxed state.

If you notice your HRV and SPO2 trending upwards, this is a sign that your wellness and stress management efforts are working. If your resting heart rate and blood pressure trend downward, this is also a sign of success.

Look at the Big Picture

Have you ever heard the phrase “fighting fit”? In general, maintaining a high fitness level prepares your body to better deal with stress. However, the combination of acute emotional stress *and* physical stress from a vigorous workout may weaken your body and mind. Factor your stress levels with your workouts. Take it easy if you are dealing with major stress like a family emergency or a big deadline.

Light-to-moderate exercise like walking, yoga, dancing, or recreational sports may give you an outlet to recover from stress. Alternately, in some cases you may actually benefit more from a power nap or practicing relaxation techniques than a workout if your stress levels are very high.

Consider Yoga, Tai Chi, or Meditation

Since deep breathing and relaxation temporarily elevate HRV (and lower pulse) these markers may also help guide your practice. Emerging research indicates mindful practices like yoga and tai chi may increase HRV, SPO2 and decrease blood pressure and resting pulse. Some tech-friendly yogis even take an HRV reading during relaxation post at the end of their practice.

Reduce or Manage Your Life Stress

Athletes don’t want to overtrain as they prepare for either a marathon or a sprinting race. The same applies to you while working on big projects, moving, or experiencing another major life change. If possible, simplify your life. Learn to say no and avoid taking on too much.

Take Care of Yourself

Generally when you take good care of yourself, your HRV, SPO2, and resting heart rate tend to improve. Even better, your body and mind are ready to face life’s challenges. The following healthy choices may improve your HRV in both the short and long term:

  • Get enough sleep
  • Eat a healthy, balanced diet
  • Drink enough fluids
  • Enjoy moderate activity most days and improve or maintain your physical fitness
  • Avoid smoking
  • Spend a few minutes relaxing each day whether you prefer to meditate, pray, do yoga, or practice breathing exercises.

Take control of your stress levels and your fitness. You can customize your lifestyle and measure results by tracking key metrics like HRV, SPO2, and resting heart rate. In the past, only elite athletes had this opportunity, but now these tools are  available to you. Thanks to fitness wearables like Biostrap you can easily take these metrics at home.

Have you ever woken up after an eight-hour night of sleep, only to still feel tired? We all have nights where we can’t sleep, whether it’s due to insomnia, hormonal changes, exercising or eating too late, or feeling anxious and restless. Not being able to sleep from time to time is an occasional occurrence for most people, but one that doesn’t cause them much trouble.

On the other hand, there are people who are tired all the time. Being constantly sleepy isn’t normal, and it could be a symptom of a more serious condition. If you’re always sleepy no matter how much sleep you get, here’s what could be causing you trouble — and how to get back to sleeping soundly.

Why Am I Always Sleepy No Matter How Much Sleep I Get?

Everyone deserves to get a good night’s sleep and wake up the next day feeling refreshed and rejuvenated. Unfortunately, this isn’t realistic for people who feel tired all the time. It can be especially frustrating for people who experience tiredness and low energy levels on a daily basis, even when they go to bed early and try to sleep all throughout the night.

The first thing to look at is the amount of sleep you get each night. The National Sleep Foundation recommends 7-9 hours of sleep per night. Yet, if someone is physically active throughout the day or has additional medical conditions, this can vary.

Sleep problems can also be a result of over-reliance on sleep medications, including synthetic pills as well as more natural approaches like melatonin or valerian. While natural remedies may be safer and have fewer side effects, relying on any type of medication to help you sleep can mask underlying sleep problems.

It may help to invest in a sleep tracker to better understand your sleep patterns during the night. A sleep tracker, like Biostrap, can help you understand how much time you spend in deep or light sleep, how long it takes you to fall asleep, how many times you wake up during the night, whether you snore or move a lot, and more. Such sleep tracker data can provide valuable insights into how much quality sleep you’re getting, and whether or not it’s time to introduce a lifestyle change.

Sleep Disorders and Persistent Tiredness

Quality sleep is essential for optimal recovery and performance, yet many people struggle with it. Are you constantly asking yourself, “Why am I tired all the time?” If so, it might be time to explore additional causes of your tiredness that may be beyond your control. Here’s a look at sleep disorders and medical conditions that may be affecting your quality of sleep and contributing to chronic tiredness.

Sleep Apnea

Sleep apnea is one of the most common medical conditions causing chronic sleepiness. Specifically, obstructive sleep apnea “occurs when your throat muscles intermittently relax and block your airway during sleep,” according to the Mayo Clinic. Obstructive sleep apnea (OSA) cannot only be serious, but it is the most common form of sleep apnea yet it’s often left undiagnosed.

According to a study published in Science Direct, “OSA affects approximately 20% of US adults, of whom about 90% are undiagnosed.”

The two main symptoms of sleep apnea are excessive daytime sleepiness and loud snoring. Sleep apnea is also a common reason why people who maintain a consistent, healthy bedtime routine still feel tired the next day. High blood pressure, being overweight, smoking, diabetes, and narrowed airways are all symptoms of sleep apnea.

One helpful solution for sleep apnea is a treatment called Continuous Positive Airway Pressure (CPAP). This is simply a face or nasal mask that offers a consistent stream of airflow into the nasal passages, keeping the airway open. This is a non-invasive treatment and can help you improve the quality of your sleep. Meanwhile, the common medical advice for overweight people with sleep apnea is to engage in lifestyle factors that promote weight loss.

Chronic Fatigue Syndrome

When you feel like you’re never getting enough sleep even though you get the recommended 7-9 hours of sleep, it could be due to chronic fatigue syndrome (CFS). This condition causes persistent daytime sleepiness regardless of nighttime sleep patterns. It can be exacerbated by intense physical activity and intellectual stimulation. In addition to causing fatigue, it causes loss of memory, sore throat, unexplained muscle and joint pain, and frequent headaches.

While the cause of chronic fatigue syndrome is still unknown, according to the Mayo Clinic, it can be triggered by a variety of factors. These include viral infections, such as herpes and epstein-barr virus. It is also commonly associated with immune system problems and autoimmune disorders. Working with a therapist to take back control of your life and optimize your daily routines can help you address many of the CFS symptoms.

Additionally, a physical therapist can help you reduce your hypersensitivity to exercise and gradually begin helping you get active, which can stimulate blood flow, boost endorphins, and support higher energy levels.

Other Health Conditions Associated With Tiredness

The quality of your sleep is largely impacted by your circadian rhythm. Also known as your sleep-wake cycle, the circadian rhythm dictates influences when you will feel sleepy and when you will be more alert.

Circadian rhythm disorders, however, can disrupt these sleep patterns and create an inconsistent sleep cycle. People’s circadian rhythm can be disrupted by inconsistent sleep schedules, especially for those engaging in shift work and those who work late into the night.

Iron deficiencies are another common reason why people are always sleepy. In fact, feeling very tired is one of the most common symptoms of an iron deficiency. “This happens because your body needs iron to make a protein called hemoglobin, which is found in red blood cells. Hemoglobin helps carry oxygen around the body,” registered dietician Mary Jane Brown said in a Healthline interview.

Additional symptoms of iron deficiency include paleness, shortness of breath, headaches, dizziness, and heart palpitations. Iron deficiencies can be caused by poor nutrition, pregnancy, and inflammatory bowel disease. The good news is that most iron deficiencies are easy to address by increasing your iron intake and maintaining a balanced diet.

Improving Your Sleep Hygiene

Poor sleep is often a side effect of poor sleep hygiene. For example, a lot of people struggle to maintain a consistent sleep schedule, which makes it hard for their body to adjust during the day. Consuming alcohol on weeknights, exercising too late in the day, using the bedroom for work, and staying on screens while in bed are a few examples of poor sleep hygiene.

Going to bed at the same time each night and setting your alarm clock for the same time each morning can create consistency in your sleep schedule and thus improve your quality of sleep.

This can get your circadian rhythm back on track. Such consistency around sleep is also a great way to train your body when to get tired in the evenings and when to wake up feeling alert. 

Removing electronics from the bedroom and staying away from screens before bed is another way to prepare your body for sleep.

Mental Health Management

Mental health is another pillar to consider when you constantly feel tired. Anxiety and stress are two common, yet often overlooked causes of fatigue. This is in part because stress may elevate cortisol levels, which in turn can disrupt a person’s ability to achieve good sleep quality.

Studies show that reducing cortisol levels and balancing the hypothalamic-pituitary-adrenal (HPA) axis can greatly improve sleep disturbances and overall sleep quality. The HPA axis is the body’s system for regulation, helping an individual to stay safe in response to constantly changing environments. This mechanism plays an important role in activating the body’s sympathetic nervous system (flight-or-fight mode), potentially causing further stress.

Taking care of your mental health can help the HPA axis to stay in balance and regulate cortisol levels so that your sleep quality won’t suffer the consequences. Regular stress management practices such as meditation, yoga, creative expression, and physical activity have all been found to help improve sleep and overall well-being, and balance the nervous system.

So, Why Am I Always Tired?

The quality of sleep you get matters. Whether you’re falling asleep at work or waking up groggy every day, it’s important to understand why you’re always tired.

If you feel like you’re sleeping for ample time throughout the night, your tiredness may be due to a sleep disorder, such as sleep apnea. It could also be related to chronic fatigue syndrome or an iron deficiency. Seeking out professional medical advice can help you get to the bottom of your persistent tiredness, so you can get back to feeling your best and stop losing sleep over it.
