Heart Rate Variability (HRV)
HRV measures the variation between heartbeats. Higher HRV generally means better cardiovascular fitness and stress resilience. Don't compare your number to others — what matters is your personal trend over time. A rising 30-day average suggests positive adaptation; a declining trend may indicate overtraining, poor sleep, or chronic stress.
Resting Heart Rate
Your resting HR reflects cardiovascular efficiency. Well-conditioned individuals typically have resting HR of 50-60 bpm. A sudden increase of 5+ bpm above your baseline may indicate illness, dehydration, or overtraining. Track the trend, not individual readings.
Sleep Metrics
Total sleep time matters, but sleep architecture matters more. Deep sleep (N3 stage) is when growth hormone is released and tissues are repaired — aim for 15-20% of total sleep. REM sleep supports memory consolidation and emotional regulation — aim for 20-25%. Consistency of bedtime and wake time is more important than total hours.
