How do I monitor my sleep?

If you wear the watch while sleeping, the watch will automatically record your sleep information. You can view sleep duration, sleep stages, sleep score, naps, and other information on the device. More information can be viewed after synchronized to the Zepp app.

Enable Assisted Sleep Monitoring for more accurate sleep information (REM sleep stage).

Enable sleep breathing quality monitoring. If the system detects that you are wearing the device during sleep, it will automatically monitor your breathing quality to help you better understand your sleep status.

How to set the above features: Open the Sleep app, swipe down to the last page, and go to sleep settings to enable or disable the above features. When the phone and watch are connected, you can also open the Zepp app and go to Profile > Amazfit T-Rex 3 > Health Monitor to complete settings.
