How the Galaxy Watch sleep apnea feature works

Users wear a Galaxy Watch to sleep for a few nights, and the sleep apnea results are divided into three stages: mild, occasional, and frequent. Samsung says this classification allows for greater specificity in condition management.

Many smartwatch and health tracker companies have implemented some sleep apnea detection features on their devices. The often underdiagnosed condition impacts around 30 million Americans, according to the American Medical Association (AMA). It’s a condition with gateway effects: if it goes untreated, it can lead to high blood pressure, heart disease, and impaired focus, according to the AMA. Despite sleep apnea’s prevalence, it’s highly treatable — and a great example of wearables passively detecting conditions at home.

Of course, the Galaxy Watch can’t aid in the treatment plan of a sleep apnea diagnosis.

The feature will be available in Korea first, starting in November, with no confirmed date for when it will arrive on US Samsung watches and smart rings. The FDA-cleared feature will first come to the Galaxy Watch Ultra 2, Watch 9, and Ring. Samsung says an update will bring the advanced sleep apnea detection to Galaxy Watch 7 and 8 through future software updates.

To use the feature, a Galaxy user will need to record two nights of sleep within a 10-day period to learn details about their condition.
