What does the Whoop sleep score indicate?

The Whoop sleep score is a comprehensive metric designed to assess the quality and restorative value of an individual's sleep. It calculates this score using various parameters such as the total sleep duration, sleep efficiency, consistency of the sleep schedule, and the amount of time spent in different sleep stages, including REM (rapid eye movement) and deep sleep, which are critical for cognitive recovery and physical repair. The score typically ranges on a scale that helps individuals understand how well they've slept, enabling them to make more informed decisions about their daily habits and routines to improve overall sleep quality, and by extension, their performance and health.
