How to Enable hypertension alerts

Not all users can turn on the feature. To activate hypertension tracking, users must be over 22 years old, not pregnant, and not have a prior diagnosis of hypertension. Wrist detection must be enabled on the watch.

Once eligibility is confirmed, users can set up hypertension tracking through the Health app by navigating to the heart section or the health checklist in their profile. The watch then monitors heart-related data over a 30-day period. If it detects patterns associated with hypertension, it will send an alert.

How it works

The watch does not send notifications during the first 30 days while collecting baseline data. After this period, if an alert appears, users are prompted to start logging blood pressure readings using a third-party cuff. Apple recommends recording readings for seven days and adding them to the Health app. Users should then consult a health professional to review the data.

Hypertension often shows no symptoms, so alerts may come as a surprise. Apple estimates that the feature could issue around one million alerts to people with undiagnosed hypertension within its first year. While the alerts provide early warnings, they are not a replacement for professional medical evaluation and may not detect every case of high blood pressure.
