What is Heart Rate Variability and How Does It Affect Your Health? -- By Conner Keyeski

Updated: Jan 24, 2021


Heart rate variability (HRV) has become a popular health and wellness measurement in recent years, thanks in part to wearable devices and mobile apps. HRV is the variation in time between each heartbeat and is regulated by our autonomic nervous system, which controls our fight or flight response. It also controls our bodily functions that perform unconsciously, such as heart rate, digestion, respiratory rate and pupillary response.


HRV is impacted by a number of factors including sleep, nutrition, physical activity, stress and emotions. If we aren’t getting enough sleep, not exercising, and eating poorly our HRV decreases. On the other hand, if we are getting adequate sleep, being physically active, providing our bodies with proper nutrition, practicing relaxation and stress reduction techniques, our HRV can increase.


Higher HRV correlates to a reduction in morbidity and mortality and an increase in psychological health and quality of life. HRV is a great way to measure and track our current health status but also can determine our longevity.


At Atma Clinic we look at ways to improve overall health and address all aspects of our patients’ well-being including physical, mental and nutritional health. We utilize the most up to date science when it comes to evaluating and treating our patients.
