Apple Watch's Sleep Apnea Detection Feature Gets Approval in Canada

Health Canada has approved the Apple Watch's sleep apnea detection feature, following FDA approval earlier this month. The feature uses accelerometer data to detect breathing disturbances during sleep.

Sleep apnea is a condition where breathing momentarily stops during sleep, preventing the body from getting enough oxygen. It affects over 1 billion people worldwide and often goes undiagnosed. Untreated, it can lead to increased risk of hypertension, type 2 diabetes, and cardiac issues.

Breathing Disturbances is an Apple Watch metric that detects small wrist movements associated with interruptions to normal respiratory patterns during sleep. Every 30 days, the watch will notify users if it shows signs of moderate to severe sleep apnea so they can consult their doctor for further diagnosis and treatment.

The feature is supported on the latest Apple Watches (Series 10, Series 9, Ultra 2) and will be available in over 150 countries and regions this month.
