High Blood Pressure – How to Control it with Exercise and Diet
When the heart pumps it exerts forces on the walls of the blood vessels which can be measured. Systolic blood pressure occurs when the heart contracts and forces blood out into circulation. When the heart relaxes and refills the pressure on the blood vessel walls decreases, this is known as diastolic blood pressure. Therefore blood pressure is measured as two readings (e.g. 120/80mmHg).
