Apple has announced a package of health features, alongside the launch of the new Apple Watch Series 11, including an alert that the wearer may have high blood pressure, also known as hypertension.
Around 1.3 billion people worldwide have high blood pressure. But almost half are unaware of their diagnosis.
This lack of awareness is often due to limited access to regular medical care, the absence of noticeable symptoms or warning signs, and because a single blood pressure reading could miss the condition.
