Sleep Apnea Detection

Apple surprised us with a new health feature during its September event that it hadn’t mentioned during its June Worldwide Developers Conference (WWDC): Sleep Apnea Detection.

According to Apple and other sources like the National Center for Biotechnology Information, over one billion people are affected by sleep apnea.

This new feature will send you notifications when it thinks it detects sleep apnea while you sleep. After you wear your Apple Watch for a few days, it will detect disturbances in your breathing using its accelerometer. If it detects anything, you’ll get a notification that you might have sleep apnea and how severe it thinks it is.

If you want more information, you can go to the iPhone’s Health app and view all the resources Apple offers.

Unfortunately, this feature isn’t available on every Apple Watch that supports watchOS 11. It can only be used on an Apple Watch Series 9, Series 10, or Ultra 2.
