What is HRV?
Heart rate variability (HRV) refers to the variation in time between successive heartbeats, defined as RR intervals. And is used to measure the activity of the autonomic nervous system. It has been said that measuring autonomic nervous system activity can provide insights into an individual's stress levels, emotional state, and overall health. Since HRV is highly individual, there is no optimal range for everyone. To derive the highest value, you should look not at the absolute values but rather at the changes in your HRV from your baseline.
👋 Optimal HRV
An increase in heart rate variability (HRV) is generally a sign of better physical fitness and less stress, whereas a decrease in HRV is a sign of overtraining and a high-stress state.

However, it is important to note that HRV is a complex metric that can be affected by many factors. Interpreting HRV changes requires careful consideration of an individual's specific circumstances and health status.
