Blood pressure is a measure of the force exerted by your blood against the walls of your arteries. It is an important indicator of your overall health and can help you assess your risk of developing heart disease, stroke, and other health problems.
There are two numbers in a blood pressure reading: the systolic pressure and the diastolic pressure. The systolic pressure is the pressure in your arteries when your heart beats. The diastolic pressure is the pressure in your arteries when your heart rests between beats.
