Do you often wake up feeling exhausted, even after a full night’s sleep? You might be one of the millions unknowingly living with sleep apnea. Now, Apple Watch can help. Apple’s latest sleep apnea detection feature is available on the Series 10, Series 9, or Ultra 2 models, turning your smartwatch into a powerful health tool.
Using its built-in sensors, the Apple Watch monitors your nighttime breathing patterns to detect signs of sleep apnea, eliminating the need for overnight lab visits or expensive equipment. With this new capability, identifying a common but often undiagnosed condition has never been easier or more accessible.
How Apple Watch detects sleep apnea using breathing disturbance data
The sleep apnea detection feature utilizes the watch’s built-in accelerometer to monitor a new metric called “breathing disturbances” during sleep. By analyzing these disturbances over time, the watch can identify patterns consistent with moderate to severe sleep apnea.
Apple Watch sleep apnea feature receives FDA approval and global rollout
Apple’s sleep apnea detection feature is officially live following FDA approval. This marks a major step forward for wearable health tech. The feature is now rolling out across more than 150 countries and regions, including the United States, Europe, and Japan, bringing sleep apnea screening directly to users’ wrists worldwide.
How users can track sleep apnea risk in the Apple Health app
You can view your nightly breathing disturbance data in the Health app on your iPhone, where it will be categorized as either “elevated” or “not elevated.” The watch analyzes this data over a 30-day period and notifies users if it detects consistent signs of sleep apnea.

```Apple Watch sleep apnea detection accuracy: What the data shows
In clinical validation studies, the notification performance achieved a sensitivity of 66.3% and specificity of 98.5%. This means that while the algorithm is effective at identifying those with moderate to severe sleep apnea, it also minimizes false positives, ensuring that you can trust the notifications you receive.

Why Apple’s sleep apnea detection could help millions go undiagnosed
Dr. Sumbul Desai, Apple’s vice president of Health, emphasized the rigorous development process behind this feature. The detection algorithm was created using advanced machine learning with extensive datasets from clinical-grade sleep apnea tests. The studies included diverse participants across various demographics and evaluated both at-home and in-lab sleeping environments.
This feature has the potential to significantly impact public health by helping identify undiagnosed cases of sleep apnea. Research suggests that up to 80% of sleep apnea cases remain undiagnosed, making this tool invaluable for many people who may not exhibit obvious symptoms.
