What lifestyle changes can I make to improve my blood pressure?
Regular exercise and eating a healthy diet will help lower your blood pressure and improve your overall health. Engage in physical activity (e.g. walking) at least 30 to 60 minutes on most days of the week. If you have not exercised for a long time, start with light exercises such as slow walks. Speak to your doctor about what type of exercise would be suitable for you.

Cutting down on deep-fried foods and using less salt when cooking can kick-start your healthy diet.
