What This Means
Elite-level nervous system health
You're in the top tier of HRV for your age group, comparable to well-trained endurance athletes. Your autonomic nervous system is highly adaptive, allowing rapid recovery and excellent stress resilience. The priority now is maintaining this through balanced training, quality sleep, and avoiding chronic stressors.
How to Improve
Maintaining your edge
- Monitor HRV trends to detect overtraining before it impacts performance
- Focus on parasympathetic activities: nature walks, social connection, creative hobbies
- Fine-tune nutrition timing around training for optimal recovery
- Manage psychological stress as carefully as physical training load
Measuring with Apple Watch
Apple Watch measures HRV during sleep using the SDNN method, sampling overnight to capture your resting autonomic nervous system state. Garmin, COROS, Polar, and Whoop also measure HRV, though methods may vary (some use RMSSD). The classification tables on this page apply regardless of which device you use. Keep in mind that HRV naturally fluctuates day to day, so focus on weekly trends rather than single readings.

Frequently Asked Questions
Is an HRV of 115 ms good for my age?
Whether an HRV of 115 ms is good depends on your age and gender. Use the chart above to see exactly where you stand. HRV naturally decreases with age, so the same value can be excellent for a 60-year-old but average for a 25-year-old. Focus on your trend over time rather than any single reading.
Can I improve my HRV from 115 ms?
Yes. HRV is one of the most responsive health metrics. Unlike VO2 Max, which takes months to change, HRV can improve noticeably within weeks. Quality sleep, regular aerobic exercise, breathing exercises, and stress management are the most effective strategies.
Why does my HRV of 115 ms fluctuate so much day to day?
Daily HRV fluctuation is completely normal. Alcohol, poor sleep, intense exercise, stress, illness, and even meal timing can lower HRV temporarily. What matters most is your 7-day or 30-day trend, not any single measurement.
How accurate is Apple Watch HRV?
Apple Watch HRV measurements are well-correlated with clinical-grade chest strap monitors. The overnight measurement approach used by Apple Watch provides a reliable baseline, as resting conditions minimize movement artifacts. For trend tracking, it is more than accurate enough.
