Samsung adds better sleep tracking to Galaxy Watches – here’s what to expect

Samsung has enhanced the sleep-tracking capabilities of its Galaxy Watches with a new AI algorithm that offers more detailed sleep reports compared to previous sleep apnea detection technology. Users can wear their Galaxy Watch for a few nights, and the sleep apnea results will be categorized into three stages: mild, occasional, and frequent.

This classification enables a more precise management of sleep conditions. Sleep apnea, although often undiagnosed, affects around 30 million Americans according to the American Medical Association (AMA). The condition, if left untreated, can lead to serious health issues such as high blood pressure, heart disease, and impaired focus.

However, it is treatable, and wearables like Samsung's Galaxy Watch can passively detect the condition at home. The feature will initially be available in Korea, starting in November, with no set date for its release in the United States. Samsung's FDA-cleared feature will first be introduced on the Galaxy Watch Ultra 2, Watch 9, and Ring models.

Future software updates will roll out the advanced sleep apnea detection to Galaxy Watch 7 and 8. To utilize the feature, users will need to record two nights of sleep within a 10-day period to gather information about their condition.
