Heart rate variability

Heart rate variability (HRV) refers to the variation in the time interval between consecutive heartbeats, reflecting the autonomic nervous system's regulation of the heart. It serves as an important indicator of cardiovascular health and overall well-being, with higher HRV generally indicating better fitness and resilience to stress, while lower HRV may signal stress, fatigue, or potential health issues. HRV is particularly valuable for athletes, healthcare professionals, and individuals monitoring their stress and health levels.
