In their words
“People who want to live longer and healthier lives should be tracking heart rate variability, coefficient of variation, HRVCV.”

Tracking HRV CV offers insight into adaptation, resilience, and health status, helping to risk stratify individuals and understand aging and metabolic health.
Improving parasympathetic output sets up the brain to maximize testosterone and androgens.
HRV can indicate if your body is paying the price and if you are running yourself into the ground during perimenopause.
