Improving Hrv Archives

First responders play a crucial role in safeguarding our communities, often facing high-stress situations that can take a toll on their mental and physical well-being. Wearable technology has provided great value in various industries for tracking health metrics, such as heart rate, sleep patterns, and physical activity. Its potential in supporting first responders is undeniable in terms of helping to enhance safety and performance, including the benefits of tracking fatigue, sleep, and recovery.

One metric that has received considerable attention in the context of first responders is heart rate variability (HRV).

What is heart rate variability (HRV)

HRV, the variation in time intervals between consecutive heartbeats. It is a measure of the balance between the sympathetic (fight or flight) and parasympathetic (rest and digest) branches of the autonomic nervous system and has proven to be a reliable indicator of an individual’s stress levels, emotional well-being, and overall health.

Utilizing wearables, such as the Biostrap devices, equipped with HRV monitoring capabilities can provide real-time data, helping first responders understand their physiological responses during high-stress situations.

Wearable Technology for Measuring HRV

Wearable technology, such as the Biostrap Kairos, EVO, and Ethos can continuously measure HRV throughout the day and night. These devices use either ECG or photoplethysmography (PPG) technology. The latter to measure the changes in blood volume in the microvascular bed of tissue, providing a non-invasive method for HRV assessment.

Advantages of Wearable HRV Monitoring

Measuring HRV offers several advantages for first responders:

Continuous, real-time monitoring provides a comprehensive picture of an individual’s HRV throughout the day, allowing for more accurate assessments of stress and fatigue levels.
Non-invasive and unobtrusive technology enables first responders to wear the devices during their daily activities and while asleep without hindrance.
Data collected from wearable devices can be easily accessed and analyzed, allowing for personalized recommendations and interventions.

Why HRV Matters for First Responders

By monitoring HRV, first responders can gain insights into their autonomic nervous system’s functioning, enabling them to identify early signs of stress and take appropriate action. This information empowers them to implement self-regulation techniques, such as deep breathing exercises and mindfulness, to manage stress and maintain their performance under pressure.

The impact fatigue

Fatigue is a significant challenge first responders face. Numerous studies have established a link between the demanding nature of their work and increased risk of this condition. Literally has shown that over 50 percent of firefighter deaths are due to stress and exhaustion.

Additionally, studies have established that chronic fatigue might reduce HRV. By harnessing the power of wearable technology, we can gather valuable insights into their physiological responses, enabling proactive measures to mitigate the risk and impact fatigue.

Sleep tracking

Fatigue resulting from inadequate sleep is a significant concern for first responders, as it can impair cognitive abilities, decision-making, and reaction times, jeopardizing both their safety and the safety of those they serve. Wearable technology with sleep tracking capabilities allows first responders to monitor their sleep patterns and ensure they are getting the rest they need.

Sleep tracking can provide valuable data on sleep quality, duration, and disruptions, helping first responders identify potential sleep disorders or patterns that may impact their performance

Armed with this knowledge, they can implement strategies to improve sleep hygiene, such as maintaining a consistent sleep schedule, creating a conducive sleep environment, and adopting relaxation techniques before bedtime. These measures can significantly enhance their alertness and cognitive functioning, reducing the risk of fatigue-related challenges on duty.

Optimizing performance and safety

By leveraging HRV and sleep tracking, Biostrap enables first responders to take proactive steps toward optimizing their performance and safety. Continuous monitoring of HRV can aid in identifying patterns that may indicate the need for extended rest or recovery periods, preventing burnout and promoting overall well-being. Additionally, sleep tracking empowers first responders to prioritize and improve their sleep, ensuring they are well-rested and mentally sharp during critical moments.

Furthermore, the data collected through wearable technology can be analyzed on a broader scale to identify trends across teams. This information can be used to develop evidence-based protocols and training programs aimed at promoting resilience, reducing stress-related incidents, and improving overall performance.

More research needed but we’re at a good start

More research is needed to better understand the relationship between HRV and job-specific stressors faced by first responders, as well as to develop targeted interventions and strategies based on HRV data.

However, wearable technology, like the Biostrap devices, that are equipped with HRV and sleep tracking capabilities hold tremendous potential in supporting our first responders. By providing valuable insights into their physiological responses, these devices offer an opportunity to manage stress, reduce the risk of fatigue, and optimize performance and safety.

As we continue to explore innovative solutions, it is essential to prioritize the well-being of our first responders and equip them with the tools they need to excel in their noble service to society.

Measuring Your Resting Heart Rate

The American Heart Association recommends that you check your resting heart rate first thing in the morning before you get out of bed. For best results, choose a morning when you wake up naturally since many of us are startled by the sound of the alarm. If that isn’t possible, try relaxing for a few minutes before you take your resting heart rate.

If you took your resting heart rate each morning, you would find that some mornings it is higher and others lower. This will vary depending on whether you are fighting illness, slept well, and where your hormonal cycle is that day (especially if you are female). Many of the same things that affect Heart Rate Variability (HRV) also may change your resting heart rate.

Please note, the information in this post is not a substitute for medical or professional advice. It is simply general information.

Three Surprising Things That Change Your Resting Heart Rate

1. Dehydration

Fitness enthusiasts often use heart rate monitors to track their working heart rate. Competitive and recreational runners may use heart rate training to ensure they work at the right intensity for each workout within their training program.

However, the benefits go deeper. An increased heart rate is also one of the symptoms of dehydration. This also can happen at rest especially on a hot day. WebMD lists increased heart rate as a warning sign of dehydration. According to WebMD, the increase in RHR also indicates the degree of dehydration:

“Normally, when you have been lying down and then stand up, there is a small drop in blood pressure for a few seconds. The heart rate speeds up, and blood pressure goes back to normal. However, when there is not enough fluid in the blood because of dehydration and the heart rate speeds up, not enough blood is getting to the brain. The brain senses this condition. The heart beats faster, and if you are dehydrated, you feel dizzy and faint after standing up.” (Source Dehydration in Adults, Web MD)

Tip or Application: Stay hydrated both at rest and during exercise to maintain your normal heart rate. Be aware that excessive hydration can lead to a rare and dangerous condition sometimes known as “water intoxication.” Always practice moderation!

2. Changes in Health

Your resting heart rate (RHR) provides a barometer into your health and hormone balance. It reflects the efficiency of your cardiovascular system much like your HRV reading. Keep in mind that your genetics affect your resting heart rate so some people tend to run a little faster while others typically have a slower RHR. However, within your normal range, the following factors can alter your RHR:

Pregnancy – pregnancy typically increases RHR very early. Sometimes women who measure their Basal Body Temperature (BBT) while trying to conceive also take their resting pulse. Often they find both their core body temperature and their heart rate increased before a home pregnancy test confirmed the result.

Thyroid conditions – People with underactive, or hypothyroid, often find their RHR decreased. On the other hand, those with overactive, or hyperthyroid, find their RHR increases.

Other hormone changes – Both of the previous factors involve a change in hormone balance, other hormone changes may also affect RHR.

Weight gain or loss – Sometimes when people gain weight their RHR increases and weight loss decreases it. Of course, improvement in cardiovascular fitness also result in a lower resting heart rate (at the lower end of your normal range).

Tip or Application: Regularly monitor your RHR and HRV. If you notice changes that last longer than a few days consider whether there may be any changes to your health or hormones. If you think so, be sure to schedule an appointment with your doctor.

3. Overtraining or Stress

We previously covered how stress can lower your HRV, it also can raise your RHR. The same applies to training hard without allowing adequate recovery from your workouts. Some athletes track both their HRV and RHR to gauge their recovery. Inadequate sleep can also hinder your ability to recover from physical and mental stress. This also results in decreased HRV readings and increased RHR.

Tip or Application: Use your Biostrap to tracks trends in both your RHR and HRV measures. Consider taking active recovery days or rest if your readings indicate that you need rest.

Your biometrics offer insight into the state of your health. Devices like Biostrap make it easier to track trends in key biometrics including resting heart rate, blood oxygen saturation levels, resting heart rate, and working heart rate. It is easier than ever to monitor these metics and to use this information to live your healthiest life.
