Apple has gradually expanded the health monitoring features of the Apple Watch over the years, moving beyond fitness tracking to areas that can provide early insight into potential health concerns. Another recent addition is hypertension alerts, which are designed to alert users when their blood pressure trends higher over time. Although Apple Watches cannot directly measure blood pressure, this feature can still play a useful role in highlighting patterns that may be worth discussing with your doctor. Here, we’ll explain what hypertension alerts do, how they work and how you can enable and manage them on Apple Watch.
What hypertension warnings do
Hypertension Alerts are designed to identify long-term trends that may indicate high blood pressure. Instead of relying on a traditional cuff measurement, the Apple Watch analyzes a combination of health data collected over a 30-day period, including heart rate, movement patterns and other status information stored in the Health app. Using this data, the system looks for ongoing changes in patterns commonly associated with high blood pressure.
If your Apple Watch detects a trend that suggests high blood pressure over time, it will send you a notification. These warnings are not intended to diagnose high blood pressure or to replace a medical examination. Instead, they serve as the first sign that something has changed and that you may want to seek additional monitoring or professional advice.
Apple insists that the hypertension warnings are intended for users who have not yet been diagnosed with high blood pressure. Instead, they are designed to raise awareness rather than confirm the situation.
Who can use hypertension warnings
Hypertension notifications require a compatible Apple Watch model (Apple Watch Series 9 or later, or Apple Watch Ultra 2 or later) paired with a supported iPhone (iPhone 11 or later). This feature also depends on the latest versions of watchOS and iOS, as it depends on updated health algorithms and background data analysis. To use hypertension alerts you must be 22 years of age or older, not pregnant and not yet diagnosed with high blood pressure. You also need to confirm that your Apple Watch Frame Discovery feature is enabled.
To get meaningful alerts, your Apple Watch needs enough data. This means wearing the watch regularly, including during sleep if sleep tracking is enabled, and keeping health information such as age, gender, height and weight up to date in the Health app. The system uses long-term trends, so alerts will not appear immediately after enabling the feature.
How to turn on hypertension alerts
Hypertension alerts are controlled by using Health app on a paired iPhone. The feature cannot be enabled directly on the watch itself. During setup, the Health app will ask for confirmation that the user has not been diagnosed with high blood pressure. It may also result in updating health information such as date of birth and blood type, as this information helps improve the accuracy of trend analysis.
To get started, open the Health app on an iPhone paired with an Apple Watch. From the main Health screen, tap your profile in the top corner. Select Health Checklist from available Features. Next, you will need to tap Hypertension Alertsconfirm your age and whether you have been diagnosed with high blood pressure or not. Tap Go ahead and follow the on-screen instructions for information on how notifications work. Once you have done this, press Done and you will be ready.
Once enabled, the feature works automatically in the background. There is no need to start manually monitoring or interacting with the feature every day.

Managing notifications and alerts
When hypertension alerts are turned on, notifications appear on both the Apple Watch and the paired iPhone. These alerts usually explain that a long-term trend of high blood pressure has been detected, along with guidance on next steps.
Users can manage how and when these notifications appear by adjusting the Health app’s notification settings. This includes choosing whether alerts appear on the lock screen, in the Notification Center or as time-sensitive notifications on the Apple Watch.
Health data related to high blood pressure alerts can be updated at any time in the Health app. Although the Apple Watch does not display a specific blood pressure number, users can view contextual information and tutorials that explain what the alert means and what actions may be appropriate.
How hypertension alerts can help
Hypertension tends to develop slowly and may not cause noticeable symptoms in its early stages. Because of this, many people do not realize high blood pressure until it is seen during a routine medical examination.
Hypertension alerts can alert you to subtle changes that may have gone unnoticed. For some users, the warning may prompt earlier discussions with a doctor, more blood pressure monitoring at home or lifestyle changes such as adjustments to diet, exercise or sleep habits.
It is important to treat these notifications as informational rather than diagnostic. The Apple Watch does not provide specific blood pressure readings and cannot diagnose high blood pressure on its own.
What to do if you get a warning
Getting a high blood pressure warning does not mean there is a medical emergency. Apple recommends using the alert as a way to monitor your cardiovascular health.
Most users choose to follow up by measuring blood pressure using a standard cuff at home or by scheduling a checkup with a healthcare professional. A doctor can provide appropriate testing, diagnosis and guidance based on clinical parameters and individual risk factors.
It is also worth reviewing lifestyle factors that can influence blood pressure, such as physical activity levels, sleep quality, stress and diet. The Apple Watch already helps track many of these areas, which can provide useful context when discussing health issues with professionals.
Limitations to keep in mind
Hypertension notices are not available in all states and may be subject to regulatory approval. The feature also requires consistent use of the Apple Watch over time to generate reliable trend data.
Most importantly, the Apple Watch does not measure blood pressure directly. Alerts are based on correlation with trends rather than specific readings, meaning they should not be used as a substitute for medical equipment or professional care.
