Latest analysis
Your wearable reports HRV every morning. Here is what it can — and cannot — tell you about recovery.
Heart-rate variability is the most-marketed recovery metric in consumer tech. The validation studies behind it measure something narrower than the dashboards imply.
A single-morning HRV reading has not been shown to predict next-day performance in individuals. Most validation is against chest-strap ECG, at rest, in small samples.

The Test Scorecard
Every test and wearable metric graded on three questions: accurate, meaningful, actionable.
- HRV Validated at rest
- Sleep staging Partial
- Epigenetic age Utility unproven
If it doesn’t help explain how science may influence performance, healthy aging, recovery or cognition, we don’t publish it.
