Sleep Score Explained
Many wearable devices provide a sleep score that summarizes sleep quality using multiple health signals. These scores combine several sleep metrics to estimate how well your body recovered during the night.
What Is a Sleep Score?
A sleep score is a combined metric used by many health apps and wearables. It evaluates sleep quality by analyzing several sleep signals collected during the night.
What Influences Sleep Score
- sleep duration
- sleep stages (deep sleep and REM)
- nighttime heart rate
- heart rate variability (HRV)
- sleep interruptions
Why Sleep Score Matters
Sleep is one of the most important factors for recovery, brain performance and long-term health. A higher sleep score usually indicates that the body had enough time to recover.
How to Improve Your Sleep Score
- maintain a consistent sleep schedule
