Best ways to Fix ‘Sleep Tracking Not Working’ on Apple Watch

Sleep tracking is one of the essential features of the Apple Watch. Your Apple Watch tracks your sleep by recording your breathing pattern and using signals from the accelerometer and heart sensor. This data is then used to map the phases of your sleep and determine how long you spent in REM sleep, Core sleep, and Light sleep. Oftentimes, your Apple Watch may stop tracking your sleep activity all of a sudden. This may be due to a number of reasons. In this article, we bring you the best ways to fix the ‘Sleep tracking not working’ issue on Apple Watch.
