Apple has launched watchOS 11, introducing a sleep apnea detection feature approved by the FDA for its Apple Watch models, including Series 9, Ultra 2, and the newly released Series 10. This feature utilizes the watch's accelerometer to monitor breathing disturbances during sleep, potentially alerting users to possible sleep apnea issues. Over 1 billion people globally are affected by sleep apnea, yet a significant number remain undiagnosed, making this feature a significant health tool. In addition to sleep apnea detection, watchOS 11 adds a Vitals app for tracking various health metrics, including heart rate and blood oxygen levels, along with a Training Load feature to help athletes monitor workout intensity. Users can now pause their activity rings without breaking streaks, and the update includes enhancements to app interactions and translations. Overall, the update emphasizes health and fitness improvements, aligning with Apple's broader health monitoring goals.
