Resting Heart Rate
Resting Heart Rate is a health-education page for Yuelu Body Age. Resting heart rate reflects how efficiently the heart works at low load, and is an important fitness signal in Body Age. Read it as trend context rather than a judgment from one day.
Role in Body Age
Resting Heart Rate contributes to the fitness dimension of Body Age. Yuelu combines it with the other sleep, activity, and fitness signals so one weak or missing signal does not define the whole result.
Current Yuelu Method
| Field | Current rule |
|---|---|
| Data source | Apple Health restingHeartRate |
| Lookback window | The last 7 completed calendar days, excluding today |
| Metric | Median daily value, recorded as medianDailyValues(days=7;excludeToday=true) |
| Missing-data rule | Missing when no recent usable value is available |
Lower and stable values usually score better. Around 40 to 60 bpm is treated as a favorable range, while persistent elevation lowers the fitness score.
How to Improve
- Use trends rather than a single day of data.
- Support the signal with regular aerobic work and enough recovery.
- Remember that illness, temperature, altitude, medication, and fatigue can affect values.
- Seek medical guidance if abnormal heart or breathing symptoms appear.
When Data Is Missing
Check Apple Health permissions, source priority, Apple Watch battery and wear time, and whether the relevant samples were recorded recently.
Rule Basis
- Yuelu Body Age follows the current in-product calculation rules for sleep, activity, and fitness signals.
