What Sleep Score Measures
Sleep Score is a health metric commonly measured by wearable devices.
Popular wearables include:
- Apple Watch
- Garmin
- Oura Ring
- Whoop
These devices analyze physiological signals to estimate recovery, stress and fitness.
Why Sleep Score Matters
This metric helps understand:
- physical recovery
- cardiovascular fitness
- stress levels
- sleep quality
Changes in this metric can indicate improvements or problems in health.
Typical Values
Typical values vary depending on age, fitness level and lifestyle.
| Age | Typical Range |
|---|---|
| 20-29 | Example |
| 30-39 | Example |
| 40-49 | Example |
| 50-59 | Example |
| 60+ | Example |
Factors That Influence Sleep Score
Many lifestyle factors influence this metric:
- sleep quality
- stress
- training load
- alcohol consumption
- illness
Tracking trends over time is more important than single measurements.

What Sleep Score Measures
Sleep Score is a wearable health metric used to interpret stress, recovery, sleep and fitness patterns.
Depending on the device, this metric helps estimate:
- recovery status
- physiological stress
- training readiness
- long-term health trends
Why This Metric Matters
A single value is rarely enough on its own. What matters most is how Sleep Score changes over time.
This metric helps you:
- detect unusual strain early
- plan recovery more intelligently
- interpret wearable data more accurately
- understand longer-term health and fitness patterns
Typical Values
| Score | Meaning |
|---|---|
| 90–100 | Excellent |
| 80–89 | Good |
| 70–79 | Moderate |
| 60–69 | Poor |
| Below 60 | Very poor |
What Influences This Metric
Common factors include:
- sleep quality
- mental stress
- training load
- alcohol intake
- illness or infection
- time of day and measurement conditions
