From CNET: The Galaxy Watch's sleep apnea feature has received approval from the US Food and Drug Administration, the tech giant announced on Friday, in the latest sign that sleep is a big part of Samsung's health-tracking ambitions.
The feature, available through Samsung's Health Monitor app, can detect potential signs of sleep apnea, which the Mayo Clinic describes as a "potentially serious sleep disorder in which breathing repeatedly stops and starts." The announcement comes after Samsung gained approval from South Korea's Ministry of Food and Safety for the feature last October.
Samsung says its sleep apnea detection tool is intended for those over the age of 22 who have not been diagnosed with sleep apnea. Users will have to track their sleep twice for more than four hours within a 10-day period to use the feature. Samsung's tool is specifically meant to detect signs of moderate to severe obstructive sleep apnea, the more common form of the disorder that occurs when muscles in the throat relax and block airflow, according to the Mayo Clinic.
Samsung has been particularly focused on sleep in recent years, as evidenced by the One UI 5 Watch software update it launched last year. The new software emphasizes sleep statistics by more prominently displaying a user's sleep score and extending sleep coaching features to the watch.
