Oura reports that heart rate variability (HRV) measures the variation in heartbeat timing, reflecting stress levels and recovery. Higher HRV indicates well-being, while lower HRV signals stress.

Heart rate variability typically decreases during stressful situations, although the heart rate increases. Managing stress levels can mean a more variable heart rate. Exercise and relaxation ...

Real-time and early detection of minute changes in the functioning of the cardiovascular system is crucial for managing ...

Your heart beats around 100,000 times every day. Heart rate is a key marker of cardiovascular activity and an important vital sign. But your pulse is not as steady as a precision clock – nor would you ...

Heart rate variability (HRV) is the variation in the time between two consecutive heartbeats over a specific period. Doctors may use HRV as an indicator for certain aspects of a person’s health, ...

New research from the University of St Andrews debunks the theory that Heart Rate Variability (HRV) is linked to aggressive behavior. HRV, or heart rate variability, measures the variation in time ...
