Samsung has received FDA approval to introduce a sleep apnea detection feature for Galaxy Watch users in the United States. This makes Samsung the first smartwatch maker to gain such approval by the FDA. The company, however, already got approval for this feature in South Korea back in October 2023.

Sleep apnea is a chronic condition that prevents a person from breathing while asleep. This can lead to reduced sleep quality and an increased risk of serious health issues like heart disease. It’s incredibly common but often undiagnosed.

While Samsung remained tight-lipped on the exact method it will use for detection, the Galaxy Watch is equipped with the necessary sensors to monitor factors associated with sleep apnea. For instance, the watch can accurately detect changes in blood oxygen levels and heart rate, which should be pretty useful for the feature to work. 

Users will need to wear the watch while sleeping for at least two nights within a ten-day timeframe to collect sufficient data for analysis. You can then view the results on the Samsung Health Monitor app. Also, it’s important to note that the feature is only for adults over 22 who haven’t already been diagnosed with sleep apnea.

Sleep apnea detection is a valuable addition to the Galaxy Watch’s suite of health monitoring features. While not a substitute for formal diagnosis, it could be life-saving by detecting sleep apnea proactively.  

Apple is also said to be working on a sleep apnea detection feature for its smartwatch. However, the company might face obstacles due to ongoing legal restrictions regarding its SpO2 sensor.

Nonetheless, the feature will be rolled out to Galaxy Watch users in the United States later this year. However, it is likely to be available only on newer models like the Galaxy Watch 5 and 6 series.
