What is Heart Rate Variability?

March 18, 2019

Researchers have started to use an interesting marker for resilience and behavioral flexibility. It is called heart rate variability (HRV). 

Have you ever wondered what the health impact of a stressful day was? Is there anything you can do today that would improve your ability to have a better day moving forward? HRV may be the piece of data that could help you answer these questions. 

HRV is simply a measure of the variation in time between each heartbeat. This variation is controlled by a primitive part of the nervous system called the autonomic nervous system. HRV indicates how easily are we able to maintain a healthy balance, i.e. how quickly do we adapt and bounce back from stressors. It is being used as a marker for resilience and behavioral flexibility.

Our preliminary beta studies which averaged 1-2 sessions of DreamSpa phototherapy a week and measured Heart Rate Variability monthly, indicated a normalization range from 30% to 72%.
