Decoding HRV

HRV is the measurement of time variation between heartbeat. This variation picks up by our autonomic nervous system (ANS), part of our central nervous system. ANS regulates our correspond mechanism like heart rate, blood pressure, digestion and breathing. ANS consist of sympathetic (fight or flight) and parasympathetic (relaxation) nervous systems according to body feedback to the brain. This mechanism is important to our survival and overall well-being.
