The Xiaomi Smart Band 8 supports the breathing score function for sleep.
The principle of the breathing score is as follows:
Snoring or other diseases (such as obstructive sleep apnea syndrome) will lead to a significant drop in blood oxygen saturation when sleeping. The band determines whether dyspnea occurs during sleep by monitoring the drop in blood oxygen saturation and the quality of sleep. Depending on the dyspnea times, the corresponding breathing score will be given in the APP. If the breathing score is poor, it will lead to fatigue and sleepiness during the day.
Turning on the breathing score function will significantly reduce the ring life of the band. It is recommended to turn it on according to your needs.
To turn it on the APP, please check the following method:
