Apple has expanded its sleep apnea notification feature to Apple Watch users in South Korea, the company announced today.
Sleep apnea is a condition in which breathing repeatedly stops and starts during sleep, often leading to poor rest. The Apple Watch detects signs of the disorder by using its accelerometer to track subtle wrist movements associated with irregular breathing patterns. When these disturbances occur repeatedly across several nights, the watch can flag a potential case of sleep apnea.
The feature is supported on the Apple Watch Series 9, Series 10, Series 11, Apple Watch Ultra 2, and Apple Watch Ultra 3, and is available in more than 150 countries worldwide. To receive an initial reading, users need to wear the watch consistently for several nights, although nightly breathing disturbances are logged in the iPhone's Health app.
Apple also provides a full list of Apple Watch feature availability on its website.
