In watchOS 9, Apple significantly improved the built-in Sleep app on the Apple Watch by adding Sleep Stages. The Apple Watch can tell you how much time you spent during the night in REM, Core, or Deep sleep as well as how much time you were awake thanks to Sleep Stages.
The Apple Watch has long lacked the sleep monitor functionality that was previously only found in third-party apps. However, a sleep app is now available on the watch, and it utilizes motion to determine how long you’ve been asleep. You must modify your charging habits and charge your Apple Watch during the day as you must be wearing it to track your sleep. If you don’t, you’ll have nothing to pay at 10 a.m. the next morning.
Additionally, you can contrast this information with the readings your Apple Watch can capture all night long of your heart rate, breathing rate, and wrist temperature (on Apple Watch 8 and Apple Watch Ultra versions). You must create a sleep routine on your iPhone or Apple Watch in order to start tracking your sleep with the device. We have mentioned steps below to Use Apple Watch Sleep Tracker

By observing your breathing patterns and analyzing data from the accelerometer and heart sensor, your Apple Watch keeps track of your sleep quality. The phases of your sleep are then mapped using this information, and the length of time you spend in REM, Core, and Light sleep is determined.
