While you sleep, you go through a cycle of sleep phases. The first phase is light sleep, followed by deep sleep. A full sleep cycle lasts about 90 minutes and is normally repeated several times each night. We deduct sleep phases from variation in decibels and sound classification in combination with some applied theory of the science of sleep.
Sleep score/quality factors in BetterSleep:
Sleep regularity (10%)
Sleep debt (45%) - hours slept compared to your goal or 7-8 hours average
Sleep interruptions (30%) - noise detected by the tracker
Deep sleep (4.5%), REM sleep (4.5%), and heavy snoring (4.5%)
Higher scores result from consistent bedtimes, sufficient sleep, and a peaceful environment.
Don't worry about low scores! Focus on feeling refreshed, practicing good sleep hygiene, and improving overall health.
