On October 14, 2026, Apple rolled out a novel function for the Apple Watch in the Chinese mainland market, designed to pinpoint indicators of moderate to severe sleep apnea. Leveraging an accelerometer, this function keeps track of respiratory disturbance information while the user is asleep, classifying it as either 'heightened' or 'not heightened.' Users have the convenience of accessing this data through the Health app on their iPhones and iPads, and they can analyze it over various timeframes, including one month, six months, or a full year. The function is compatible with Apple Watch Series 9, Ultra 2, and SE 3, along with later models, and is tailored for users aged 18 and over who have not received a prior diagnosis of sleep apnea.
