Apple Watch users in Brazil gain access to sleep apnea detection feature

Apple has launched sleep apnea detection for Apple Watch users in Brazil, following its introduction with watchOS 11 in September. This feature is now available after receiving approval from Brazil's health regulator, ANVISA. The sleep apnea detection uses the Apple Watch accelerometer to identify breathing disturbances during sleep. It analyzes data every 30 days and notifies users of potential signs of moderate to severe sleep apnea. This feature is already available in over 150 countries, including the U.S., Canada, and the U.K. Users need to ensure their devices are running iOS 18 and watchOS 11 to access the notifications.
