As we all know, various smart bracelets can track physical indicators such as sleep state and heart rate. However, can users with APPLE WATCH now use the watch to track physical indicators such as heart rate during sleep? The answer is yes, but you must turn to third-party applications.

Before determining the heart rate index of using APPLE WATCH to track sleep, you need to consider the following two points in advance:

First of all, users should adapt to wristbands and sleep with APPLE WATCH. In addition, when the wrist moves up during sleep, the APPLE WATCH will glow. So please turn off this wake-up screen function every night, that is, press the crown, and then press General >; Wake up the screen. Another way is to slide the watch up and click the cinema mode, or you can turn off this function and notification function.
