In September 2025, Apple introduced its Apple Watch Series 11 and Apple Watch Ultra 3 in the Indian market, and these smartwatches arrived with an all-new hypertension notification feature. This feature alerts users if signs of chronic high blood pressure or hypertension are detected.
Recently, Apple has announced that this feature is now available for selected Apple Watches (Apple Watch Series 9 and later, Apple Watch Ultra 2 and later) in India.
This feature uses data from the optical heart sensor to analyse how a user’s blood vessels respond to the beats of the heart. The algorithm works passively in the background, reviewing data over 30-day periods, and will notify users if it detects consistent signs of hypertension. These notifications provide users with valuable insights into their health by simply wearing their Apple Watch.
This will help them in making lifesaving behavioural changes or start treatment to reduce their risk of serious, long-term health events. With the reach of Apple Watch, the feature is expected to notify over 1 million people with undiagnosed hypertension within the first year.
In case you receive a hypertension notification, it is advisable to log your blood pressure for seven days using a third-party blood pressure cuff and share the results with your provider at your next visit, which is consistent with the latest American Heart Association guidelines for the diagnosis and management of hypertension.
Do note that this feature is not intended for use by people under 22 years old, those who have been previously diagnosed with hypertension, or during pregnancy.
