What Your Heartbeat Hides
Your heart doesn’t beat like a metronome. The tiny variations between beats — measured in milliseconds — reveal more about your health than almost any other metric. This is HRV: Heart Rate Variability.
Higher HRV = Younger Body
Research from the European Heart Journal (2024) confirms: HRV is inversely correlated with all-cause mortality. People with high HRV for their age have biological ages 5-10 years younger than their chronological age.
What Wellex Measures
Your band tracks HRV continuously — not just during sleep (like most wearables) but throughout the day. This gives the AI a complete picture: how you respond to stress, recover from exercise, and recharge during rest.
How to Improve Your HRV
The top 3 factors from our data (12,000 participants):
- Sleep consistency — Same bedtime ±30 min. Impact: HRV +8ms average.
- Daily movement — 30 min moderate activity. Impact: HRV +5ms average.
- Stress management — 5 min daily breathing practice. Impact: HRV +6ms average.
HRV and Your Yield
Higher HRV directly improves your WVI. The AI weighs HRV heavily because it’s the most reliable indicator of overall health. Improve your HRV → watch your yield climb.
