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.

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.

How to Improve

  • Use the related current pages as the practical guide.
  • Compare trends across several days or weeks.
  • Check Apple Health permissions and Apple Watch recording quality.
  • Prioritize sleep, sustainable activity, and recovery before chasing a score.

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.
  • Data is read from authorized Apple Health and Apple Watch samples when permission is granted.
  • Interpretation is for wellness education and product explanation, not medical diagnosis.
