Expanded sleep functions are now available on Apple's smartwatches in additional nations
The Apple Watch's latest health feature, sleep apnea detection, is now accessible to users in Australia. This innovative tool, available on the Series 9, Series 10, and Ultra 2 models, leverages the watch's built-in accelerometer to monitor subtle wrist movements associated with breathing during sleep [1][2][4].
The Australian Therapeutic Goods Administration (TGA) has granted clearance for the feature, indicating a government-trusted endorsement of its medical-grade capabilities [1]. However, it is important to note that the Apple Watch is not a diagnostic tool and users are encouraged to seek professional medical advice for formal diagnosis.
The sleep apnea detection is a passive feature, requiring no additional setup. The accelerometer's sensitivity allows it to pick up small motions of breathing, even at the wrist [1]. While the exact sensitivity, specificity, and positive predictive value of the feature have not been publicly disclosed by Apple, the TGA clearance suggests that the data is sufficient for medical-grade screening [1].
The primary value of this feature in Australia lies in its potential to screen for undiagnosed sleep apnea cases. Given that up to 80% of people with sleep apnea may be unaware of their condition, even a moderately effective screening tool could have significant impact [1]. However, the watch's effectiveness depends on consistent wear and accurate data collection over multiple nights.
The sleep apnea detection feature is part of Apple's recent initiative, "Beyond Sensor," which is spearheaded by the Wearable Behaviour Model (WBM). This advanced AI model extracts health insights from passive behavioral data [5]. A subsequent validation study confirmed that individuals identified by the algorithm all had at least mild sleep apnea [6].
The sleep apnea detection feature is now available in over 150 countries and regions, including the US, EU, and Japan. Samsung has also introduced its latest lineup of health-focused wearables, emphasising that this feature is not a diagnostic tool but a screening aid [7]. Both companies' health tools aim to provide users with valuable insights into their health and encourage them to seek professional care when necessary.
In summary, the Apple Watch's sleep apnea detection offers Australian users a convenient, TGA-cleared way to screen for potential sleep apnea by passively monitoring breathing patterns during sleep [1][2]. While its accuracy is likely sufficient for raising awareness and prompting medical follow-up, it is not a replacement for professional diagnosis. Its greatest value lies in helping the large population of undiagnosed individuals seek appropriate care [1]. Users should view this feature as a first step in health awareness, not a definitive medical assessment.
