How to Measure Your HRV
HRV (Heart Rate Variability) measures the variation in time between heartbeats. Higher HRV generally indicates better cardiovascular fitness and stress resilience.
- Use a chest strap (Polar H10) or smartwatch (Apple Watch, Garmin, Fitbit) that tracks HRV
- Measure in the morning right after waking up, before getting out of bed
- Look for RMSSD value in your device's app — this is the most common HRV metric
- Track consistently at the same time for meaningful trends
