There have been relatively few rumors about the Watch Series 10 ahead of Apple's event next week, where it's expected to debut alongside the iPhone 16.  This supports a report from Bloomberg today that the Watch Series 10 will be able to identify if someone is showing 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 recommend that they see a medical provider for more tests. 

Some other possible upgrades to the Watch Series 10 include a slightly larger screen and thinner body, as well as better water resistance to support the depth of Apple Watch Ultra apps. According to 9to5Mac, Apple can also adjust the way its sensors process health data. This may begin to find a sign of atrial fibrillation for healthy applications, not the Apple Watch. Despite all these new additions, see. 9: The blood oxygen sensor still lacks excellent properties. Apple removed the sensor from existing watches after a patent dispute with Masimo.
