As watchOS 26 is released today, Apple has activated its new Hypertension Notifications feature for compatible Apple Watch models in the United States and numerous other countries. This innovative feature, which received clearance from the U.S. Food and Drug Administration (FDA) last week, is now live on the watchOS 26 and iOS 26 Release Candidate versions, just hours before the public release of these software updates.
Apple has announced that the Hypertension Notifications feature will be accessible in more than 150 countries and regions throughout the month, pending necessary regulatory approvals. The company confirmed that it has also received marketing authorization from various global health authorities, including those in the European Union (EU). According to discussions on the MacRumors forums, users in countries such as the UK, Denmark, France, Germany, Italy, Portugal, Poland, the Netherlands, and Hong Kong have already seen the feature go live. However, it is important to note that the feature is not yet available in Canada.
The Hypertension Notifications feature is designed to alert users if it detects signs of chronic high blood pressure or hypertension. Utilizing data from the Apple Watch's optical heart sensor, this feature analyzes how users' blood vessels respond to heartbeats. The advanced algorithm operates passively in the background, continuously reviewing data over 30-day periods. If consistent signs of hypertension are detected, users will receive notifications to alert them of potential health concerns.
Apple emphasizes that the Hypertension Notifications feature underwent extensive scientific validation. It was developed using advanced machine learning techniques and training data derived from multiple studies involving over 100,000 participants. Furthermore, its performance was validated through a clinical study that included more than 2,000 participants, ensuring that the feature delivers accurate and reliable results.
It is crucial to note that the Hypertension Notifications feature is not intended for use by individuals under the age of 22, those who have already been diagnosed with hypertension, or pregnant individuals. Apple encourages users to consult with healthcare professionals if they have concerns regarding their blood pressure or overall cardiovascular health.
As Apple continues to innovate in the health technology sector, the introduction of the Hypertension Notifications feature marks a significant advancement in personal health monitoring, potentially aiding users in managing their health more effectively.
