  • Movement during sleep
  • Heart rate variability (HRV)
  • Resting heart rate
  • Blood oxygen levels (SpO₂) in some models
  • Sleep duration
  • Sleep stages

Many watches combine this information to generate a sleep score or recovery score.

A best fitness watch with sleep tracking enables one to measure not only how active their lifestyle is in terms of sleep, but it also tells you the hours that one spends sleeping, their sleep stages, whether one can get back into normal function after the prior day’s activities, or whether one may even be experiencing prolonged sleep changes.

One cannot replace this lifestyle tracker as a professional evaluation should they need one to undergo screening for sleep issues.
