Do smart watches follow sleep apnea?

Yes, but ... nuance! Connected watches like the Apple Watch Series 10, the Samsung Galaxy Watch Ultra or the Galaxy Watch 7 now incorporate advanced functions for signs of sleep apnea. They use sophisticated sensors (accelerometer, oximeter, cardiofrequency meter) and artificial intelligence algorithms to analyze your sleep cycles, movements, breathing and blood oxygen levels.

• They identify nocturnal respiratory disruptions.
• They measure oxygen saturation (SPO2) and heart rate.
• They alert the user in the event of suspected moderate to severe sleep apnea.

But beware: no watch made a medical diagnosis. They serve as an early alert tool, no substitute for laboratory polysomnography.

What watch for sleep apnea? The real comparison

My clear opinion:For general public follow -up, Apple Watch Series 10 and Samsung Galaxy Watch Ultra are the references.For a medical analysis at home, the Withings Sleep Analyzer remains the reference (sensor under certified mattress).The other watches follow up on sleep, but no apnea detection worthy of the name.

How does it work? Technology

• Accelerometer : detect the micro-movements of the wrist linked to respiratory disturbances.
• Oximeter : Measures the oxygen saturation of the blood, a key indicator of sleep apnea.
• Heart frequency sensors : Reprise abnormal variations at night.

The algorithm analyzes this data on several nights (30 days for Apple, 2 days for Samsung) and sends a notification if signs of sleep apnea are detected.

Limits and traps to avoid

• No watch made a medical diagnosis. Notifications are alert signals, not verdicts.
• Variable reliability depending on the model, age, port conditions, involuntary movements, etc.
• Need to consult a doctor in case of suspicion, for a complete sleep test (polysomnography).

Testimony: "My watch saved me life"

Paul, 46, a dynamic frame, just thought of sleeping badly:“I bought an ultra galaxy watch to follow my training. After a few weeks, the watch alerted me to signs of sleep apnea.
