New research highlights how combined heart rate variability (HRV) measures, including nonlinear metrics, can help assess ...

tracking your heart rate variability (HRV) is more complicated. While it used to require getting hooked up to an EKG at your doctor’s office, new smartwatches and other wearables have made your ...

HRV has long been used by elite athletes to dictate their training schedule and it has now become a "buzzword" among the broader community.

The following is a summary of “Dynamics in physiological acute stress response trajectories: uncovering latent variability,” ...

Exercise too close to bedtime may affect sleep duration, timing and quality, new research led by Monash University has found.

Millions of people now start their day with a number—a "readiness" score, a "body battery"" level or a measure of ...

Many people are wearing Oura rings, a smart device that tracks health metrics. One of the things it tracks is your HRV, or heart rate variability. Dr. Archelle Georgio explains what that means.

Brazilian researchers reveal that even mild cases of COVID-19 can temporarily reduce heart rate variability, with stress on the autonomic nervous system lasting up to six months—especially in ...

The measurement of heart rate variability (HRV) is a remarkable index of cardiac autonomic dysfunction. The aim of this study was to examine the effects of long-term exercise training on HRV in type 2 ...
