Heart Rate Variability (HRV) is a great indicator of what is going on inside your body. It's a measurement of how well the mind can slow heart rate (HR), which is an indicator of overall health and stress. In general, better health is indicated using HRV when there is more variability from an in-breath (HR speeding up) to an out-breath (HR slowing down).
HRV measurement tracking can be used for many different things for example:
1.Health conscious individuals trying to improve their mind/body.
2.Understanding if you are coming down with some time of sickness or ailment and it's a good time to take it easy.
3.Long term is to understand your risks related to heart issues.
