INFORMATION ON BLOOD PRESSURE

What is blood pressure?
Blood is sent to the arteries with the action of a pump called heart (contraction and
dilation). The pressure of blood leaving the heart is called "blood pressure".
Blood pressures pulsate with each beat of the heart. The high blood pressure when
the heart contracts are called "systolic pressure" and the low blood pressure when
the heart dilates is called "diastolic pressure". The threshold value for hypertension
in adults is defined by the World Health Organization (WHO) as 140/90 mmHg.
Health and blood pressure
When people reach middle age, the risk of hypertension markedly increase.
With aging, the blood vessels age rapidly. Furthermore, because of the
obesity and lack of exercise, cholesterols stick to blood vessels, causing them
to lose elasticity. Therefore, watching daily blood pressure help to evaluate
our health condition.
