Issues of the sleep apnea feature on HUAWEI watches/bands

Sleep apnea occasionally reports false positives

• Wearing the device too loose or too tight can affect signal quality and may lead to occasional abnormal detections. The correct tightness is when, after wearing it, the gap between the watch strap connection structure and your wrist can fit half to one little finger. The device should be worn as shown in the following picture, with at least one finger's distance from the wrist bone. After putting it on, the device should not easily slide up or down on your arm and should not cover any jewelry or other objects.

• Consuming alcohol or other psychoactive drugs, excessive fatigue, physical discomfort (such as a cold that causes airway congestion), and tossing and turning during sleep can lead to occasional abnormal detections.

No sleep apnea results are displayed

For details, refer to My HUAWEI watch/band does not display sleep apnea results.

Sleep apnea results show Mild, Moderate, and Severe, but I personally feel fine

• If this is the first time it has occurred, check for any occasional false positives related to sleep apnea, and continue wearing the device to monitor your sleep.
• If the results show Moderate or Severe more than 80% of the time over a two-week period, and this occurs more than five times, you may have obstructive sleep apnea syndrome. It is recommended that you visit a hospital for further examination. The results from the hospital shall prevail. You can go to departments such as Pulmonology, Otolaryngology, Sleep Center, or Neurology. Search for "sleep apnea" to find the appropriate department and specialist at your chosen hospital.
• If it's just a rare occurrence, you can rest assured. Just try to sleep on your side and make sure you wear the device correctly.

I snore during sleep, but the sleep apnea test shows no abnormalities

• This feature is designed to monitor obstructive sleep apnea syndrome, not snoring. If you want to monitor your snoring at night, you're advised to use the Sleep sound recording feature in the Huawei Health app under Sleep. To enable this feature on an Android/HarmonyOS phone, open the Huawei Health app, go to Health > Sleep, tap in the upper right corner and then Sleep settings > Sleep sounds, and toggle on the switch for Sleep sound recording.
• Snoring can be caused by various factors, including obstructive sleep apnea syndrome, but not everyone who snores has the syndrome. Snoring can also be related to issues like a narrow airway or obesity. It's normal to show no abnormalities if you snore but don't have sleep apnea. If you have concerns, you're advised to undergo professional sleep monitoring and relevant tests to get an accurate diagnosis and appropriate treatment.
