Apple Watch users in seven new countries can now receive hypertension notifications, a key step toward proactive heart health. Apple has officially rolled out this feature in Australia, Malaysia, Colombia, Indonesia, South Korea, Brazil, and Turkey. The expansion allows more people to monitor high blood pressure, a condition often called a “silent killer” because it frequently shows no symptoms.

How Apple Watch Detects Hypertension

The hypertension detection feature, introduced last September, relies on advanced sensors and algorithms in the Apple Watch. By analyzing heart rate patterns and other health metrics over a 30-day period, the watch can identify signs of consistently high blood pressure. When potential hypertension is detected, the Apple Watch sends an alert encouraging users to consult a doctor and monitor blood pressure more regularly.

This technology isn’t meant to replace professional medical advice but acts as an early warning system, prompting users to take preventive steps before serious health issues arise. Apple emphasizes that early detection can play a critical role in avoiding heart attacks, strokes, and kidney disease.

Why Early Detection Matters

Hypertension affects roughly 1.4 billion adults worldwide and is the leading modifiable risk factor for heart disease. Because most people with high blood pressure do not experience noticeable symptoms, many remain unaware of their condition until complications occur. By providing timely alerts, Apple Watch helps users take control of their health, potentially reducing the risk of severe outcomes.

Health experts note that regular monitoring and lifestyle changes—such as improved diet, exercise, and stress management—can significantly lower blood pressure. Apple’s feature provides an accessible way for millions to stay informed and take early action.

Countries Now Supported

With this update, Apple Watch users in Australia, Malaysia, Colombia, Indonesia, South Korea, Brazil, and Turkey can set up hypertension alerts directly in the Health app. Users need to opt in to activate the feature and will receive notifications if the watch detects signs of elevated blood pressure over time.

This rollout reflects Apple’s ongoing commitment to expanding health features globally, making its wearable devices more than just fitness trackers. It also demonstrates the potential of consumer technology to support medical awareness and preventive care.

Which Devices Support Hypertension Alerts

Hypertension notifications are available for Apple Watch Series 9 and later, as well as Apple Watch Ultra 2 and later models. Users should ensure their devices are running the latest version of watchOS 26 to access this feature. Setting up alerts is straightforward and can be managed entirely through the Health app, making it simple for users to start monitoring their heart health immediately.

Apple and Preventive Health

Apple’s expansion of hypertension alerts underscores a broader trend in wearable technology: using data-driven insights to promote preventive healthcare. By alerting users to potential health risks before symptoms appear, devices like Apple Watch empower people to take control of their well-being. As more countries gain access to these tools, millions of users worldwide may benefit from earlier detection and intervention for high blood pressure.

Apple continues to innovate with health-focused features, from heart rate monitoring to sleep tracking, positioning the Apple Watch as a key device for maintaining long-term health. With the addition of hypertension notifications in these seven countries, Apple Watch strengthens its role as a daily companion for proactive wellness.
