After often sleeping with a bracelet, the bracelet can automatically identify the sleep state through the built-in sensor.
When it is monitored that the wearer sleeps from 22: 00 on the same day to 8: 00 on the next day, and the sleep time is greater than 1 hour, it can be recorded as main sleep.
Sleep (night sleep); Sporadic naps are recorded when the interval from the main sleep exceeds 60 minutes and the sleep duration exceeds 20 minutes. absent
20 minutes of sleep will not be recorded.
Note: If automatic heart rate detection or auxiliary sleep monitoring is not turned on, the bracelet will also detect basic sleep activity, but it is the time to fall asleep/wake up.
The accuracy of detection and sleep grading will be reduced. In order to monitor sleep more accurately, it is suggested to turn on auxiliary sleep monitoring.
