Apple Watch Series 10 rumored to add sleep apnea detection

Accommodation Bahrain introduces

Rumors about the Watch Series 10 have been relatively scant in the runup to Apple's event next week, where it's expected to debut alongside the iPhone 16. However, a report from 9to5Mac says it will have an upgraded ECG sensor capable of detecting sleep apnea.

That backs up today's reporting from Bloomberg, which says the Watch Series 10 will be capable of identifying whether someone shows signs of sleep apnea - a condition that causes people to suddenly stop breathing during sleep. If the watch determines that the user may have sleep apnea, it will then recommend that they see a medical provider for more tests.

Some other upgrades potentially coming to the Watch Series 10 include slightly larger displays and a thinner case, as well as better water resistance that will allow for support of the Apple Watch Ultra's Depth app. As reported by 9to5Mac, Apple may also make adjustments to the way its sensors process health data. It could start looking for signs of atrial fibrillation on the Health app instead of on the Apple Watch.

Despite all these new additions, there may still be one big feature missing from the Watch Series 9: a blood oxygen sensor. Apple removed the sensor from existing watches following a patent dispute with Masimo.
