Heart rate variability (HRV) is the physiological phenomenon of the variation in the time interval between different heartbeats.
For years the health and fitness industry has relied on (resting) heart rate as a measure of a client’s wellness. If a client has a lower resting heart rate, they are considered healthier than a client with a higher resting heart rate. But what if we told you there was a much better overall health indicator – and that health indicator was Heart Rate Variability?
HRV is a tool that can be used to determine how a person’s (autonomic) nervous system is functioning on a moment-by-moment and day-by-day basis. The autonomic nervous system is tied to every automatic process in the body and is comprised of two main branches that control the body’s stress and recovery processes.
