Apple Explains How Hypertension Alerts Work on Apple Watch

Apple Watch now warns users about potential hypertension. The new feature debuted in watchOS 26. It is available on Series 9 models and later. This includes the Apple Watch Ultra 2.

The system uses an innovative algorithm. It analyzes existing heart rate sensor data. No new hardware is required. According to Reuters, this software-based approach makes the tool widely accessible. Users receive an alert if signs of chronic high blood pressure are detected.

How Apple Watch Hypertension Detection Works

The feature requires an initial setup. Users must enable it within the iPhone Health app. Data collection then begins automatically.

The watch needs 30 days of heart rate information. The algorithm scrutinizes this month-long dataset. It looks for patterns consistent with hypertension.

If a risk is identified, a notification appears. The alert suggests using a blood pressure cuff for verification. Apple emphasizes this is a screening tool, not a diagnostic device.

Guidelines and Recommendations for Users

This health feature has specific user criteria. It is designed for adults aged 22 and older. It is not intended for pregnant individuals.

People with a known hypertension diagnosis should not use it. The tool aims to catch previously undetected issues. It serves as an early warning system.

Upon receiving an alert, a guided protocol starts. Users are prompted to create a Blood Pressure Log. They should use a clinical-grade device for measurements.

The log involves twice-daily checks for one week. All data is stored securely in the Health app. This information can be shared directly with a doctor.

Apple’s hypertension feature represents a significant step in proactive health monitoring. It empowers users with critical health insights. This innovation could help millions identify hidden cardiovascular risks early.
