How To Improve Your Heart Rate Variability (HRV)

Heart rate variability (HRV) is one of the most powerful metrics for understanding your recovery and resilience. In this week’s episode of the WHOOP Podcast, WHOOP Global Head of Human Performance and Principal Scientist Dr. Kristen Holmes and WHOOP Staff Research Scientist Dr. Greg Grosicki explain what HRV actually measures and what it indicates about the health of your autonomic nervous system. They unpack the biggest factors that influence HRV, including sleep consistency, hydration, training load, psychological stress, alcohol, and illness. You'll learn how to use HRV as a practical guide to balance stress and recovery, identify which habits are helping or hurting your physiology, and make small, consistent lifestyle changes that support better performance, healthier aging, and greater resilience over time.
