TIPS ON TAKING YOUR BLOOD PRESSURE

Blood pressure is a measurement of the force exerted by the heart in pumping the blood through the arteries
and the resistance by the veins in this flow.
Blood pressure varies all the time, influenced by mental and physical factors and is

In general, blood pressure is highest during the working hours and gradually decreases during the afternoon and
evening hours. It is low during sleep and increases at a relatively fast rate after arising from bed.
