NuCalm and Heart Rate Variability (HRV)

NuCalm moves the HRV measurement in the direction of rest & repair every time.

NuCalm works by priming the parasympathetic “rest and repair” side of the Autonomic Nervous System (ANS) which enhances heart rate variability (HRV).

Heart Rate Variability (HRV) is currently the best non-invasive tool to assess the overall functioning of the Autonomic Nervous System (ANS), which as we know, plays a vital role in overall health, recovery, and stress management.

HRV simply refers to the difference in length between each heartbeat. Having variety in your heart beats, indicates excellent heart rate variability and a positive reading on the parasympathetic nervous system. A decrease in, or lack of, heart rate variability is associated with sympathetic dominance and is a common risk factor for virtually all chronic diseases, regardless of a person’s age. Research has shown that lowered HRV is associated with premature aging, inflammation, depression, anxiety, etc.

What is HRV and Why Should We Care?
Recently, many consumer fitness trackers are advertising their ability to track heart rate variability, or HRV for short. Well, what is HRV? Why are physicians using it on their patients to measure overall health, athletes to measure recovery, and the everyday person to measure stress? HRV is currently the best non-invasive tool to assess the overall functioning of the Autonomic Nervous System (ANS), which as we know, plays a vital role in overall health, recovery, and stress management.

HRV simply refers to the difference in length between each heartbeat. You might think that if a person had a pulse rate of 60 beats per minute, then each beat would last for exactly one second. However, this is not the case as there are always some differences between the beat to beat duration. The more variation between heartbeats, the greater the HRV, and the more balanced the ANS.

 

The reason HRV analysis is so effective at measuring ANS activity is because your heart is largely regulated by your ANS. For example, when you experience stress, the sympathetic nervous system increases your heart rate and decreases HRV so you can efficiently manage the stress. After the stress passes, the parasympathetic nervous system slows the heart rate and increases HRV to reestablish homeostasis or internal balance. In a parasympathetic state, your body and heart need variability in order to be able to quickly transition back to a sympathetic state if another stressor arises and your survival depends on it.

Tracking Your HRV
Tracking your HRV can give you an indication of your overall health, how well you are recovering, and how well you are managing stress. A larger HRV score would reflect good overall health, efficient recovery, and good stress management. A lower HRV is a common risk factor for nearly all chronic diseases, regardless of a person’s age. Research has shown that lowered HRV is associated with premature aging, inflammation, depression, anxiety, PTSD, panic disorders, decreased autonomic nerve activity, and an increased risk of sudden cardiac death after acute heart attack. However, it is important to note that many things can influence HRV in both short-term and long-term, such as breathing, exercise, stress, medication, age, and sex to name a few.

While there are a variety of consumer HRV monitors on the market, they do not all reflect the same HRV score and are not all equally effective. HRV analysis can be relatively simple and only look at the time differences between each heartbeat. It can also dig a little deeper and run other analyses for the most thorough understanding of HRV and ANS activity. Sadly, due to certain restrictions, consumer friendly HRV wearables available on the market today, mainly focus on the simpler forms of HRV analysis and therefore do not always paint a full picture of HRV.

NuCalm’s Impact on HRV
NuCalm’s partners at Harvard Medical School, along with many clinical NuCalm users, have used research-grade electrocardiography (ECG) devices with the most advanced analytical algorithms to measure NuCalm’s effect on HRV during a single session. This research shows that within minutes of application, NuCalm effectively decreases heart rate and increases HRV, as the body enters a parasympathetic dominant state. With consistent use, NuCalm will establish and maintain balance within the ANS, which will subsequently elevate HRV scores to a healthy level. While there are still some discrepancies in the consumer HRV monitoring world, we still encourage you to look at your HRV trends on and off NuCalm, while keeping in mind that this may provide a snapshot of your HRV information.
