Apple Watch sleep apnea detection available with iOS 18.1 beta 6

Apple last month announced a new sleep apnea detection feature for Apple Watch. The feature was still unavailable to users running iOS 18.1 beta. However, iOS 18.1 beta 6 finally enables sleep apnea detection for compatible Apple Watch models paired with an iPhone running beta software.

As confirmed by 9to5Mac, iOS 18.1 beta 6 lets users enable sleep apnea detection. After updating the iPhone to the latest beta available, users will see the option to enable sleep apnea detection in the Sleep Settings within the Watch app.

iPhone and Apple Watch users who were not in beta could already use sleep apnea detection, but the feature only arrived today for those running iOS 18.1 beta. Of course, you need a compatible Apple Watch. In this case, sleep apnea detection works with Apple Watch Series 9 and later and Apple Watch Ultra 2.

However, similar to other health features, it requires approval from regulatory agencies in each country. For this reason, it’s not available everywhere.

The feature is based on the Apple Watch’s accelerometer, which is able to detect potential breathing disturbances during sleep. The feature requires wearing the Apple Watch for a few nights before you can receive sleep apnea notifications. Here’s how Apple describes it:

Sleep is an important area of health as it impacts a person’s overall physical and mental wellbeing. Sleep apnea is a prevalent disorder in which breathing momentarily stops during sleep, preventing the body from getting enough oxygen. The condition is estimated to impact more than 1 billion people worldwide, and in most cases, goes undiagnosed. If left untreated, it can have important health consequences over time, including increased risk of hypertension, type 2 diabetes, and cardiac issues.

Breathing Disturbances is an innovative new Apple Watch metric that uses the accelerometer to detect small movements at the wrist associated with interruptions to normal respiratory patterns during sleep. Every 30 days, Apple Watch will analyze breathing disturbance data and notify users if it shows consistent signs of moderate to severe sleep apnea so they can speak to their doctor about next steps, including potential diagnosis and treatment.

Apple says sleep apnea detection on Apple Watch is now available in more than 150 countries and regions, with more to come in the future. You can find the full list of supported countries on the Apple website.
