Tracking & Data
HRV Tracking
Heart rate variability reflects autonomic nervous system balance.
What
HRV (Heart Rate Variability) measures the variation between heartbeats. Higher HRV generally indicates better stress resilience and autonomic nervous system health.
Why
Low HRV is associated with chronic stress, inflammation, and poor recovery. In serious illness contexts, tracking HRV helps monitor stress load and recovery capacity.
Evidence
Multiple studies link higher HRV to better health outcomes. HRV biofeedback and mindfulness practices have been shown to improve HRV over time.
Implementation
Track daily using a compatible device (Oura, Whoop, Apple Watch). Review weekly trends.
Caution
HRV varies significantly between individuals. Focus on your own trends, not absolute values compared to others.
