Sleep monitoring is to monitor the state of people from they fall
asleep to wake up naturally. The watch can record the time of
deep sleep and light sleep.
Deep sleep refers to such a state as small body movement and
low heart rate during sleep. Light sleep refers to such a state as
big body movement and high heart rate during sleep.
The default sleep monitoring starts from 9: 30 p.m. to 12: 00 p.m.
of the next day. When sleeping out of this time period, the sleep
data will not be recorded or displayed. When sleeping,
you need to wear the watch properly.
Note: The monitoring results may differ due to different watch
