Sleep Score
Sleep Score is a health-education page for Yuelu Body Age. Sleep Score is a legacy Body Age entry; the current main model splits sleep into sleep duration and sleep regularity. Read it as trend context rather than a judgment from one day.
Role in Body Age
Sleep Score is kept for older app entry points and user education. The current Yuelu Body Age model uses the split signals shown on the related pages, which makes the result easier to explain.
Current Yuelu Method
| Field | Current rule |
|---|---|
| Data source | Apple Health sleepAnalysis |
| Lookback window | Legacy entry; current Body Age uses split sleep metrics over a 180-day stable layer |
| Metric | Legacy sleep summary; not used directly by the current main result |
| Missing-data rule | This legacy entry does not affect the current Body Age main result |
Treat the older Sleep Score entry as a sleep-health overview; in the current model, adjust sleep duration and sleep regularity first.
