How is the Score Calculated?#
Your Sleep Score is calculated based on five key dimensions: Time Asleep, REM & Deep Sleep, Sleep HRV, Stability Index, and Spindle Index. Each dimension is weighted differently to reflect its impact on overall sleep quality.
| Dimensions | Weights | Formula | Notes |
|---|---|---|---|
| Time asleep | 35 | Total time / Goal time * 35 | The default goal is 8 hours. You can set your own. Try to reach your goal. |
| REM & deep sleep | 20 | ((REM + Deep sleep time) / Total time / 40%)* 25 | The ideal percentage of REM and deep sleep is 40%. |
| Sleep HRV | 15 | HRV index 100% 15 | 0-100 |
| Stability index | 15 | Stability index 100% 15 | 0-100 |
| Spindle Index | 15 | Spindle index 100% 15 | 0-100, the higher the score, the better you can have a sound sleep, not disrupted by others or the environment. |
