Q:

What is normal blood pressure?

A:

According to About.com, normal blood pressure is 120 millimeters of mercury during a heart contraction and 80 millimeters of mercury during relaxation. This results in blood pressure readings in the range of 120/70 to 140/90. Blood pressure readings that surpass that amount points to high normal blood pressure and hypertension.

About.com states that blood pressure readings may vary in each body, and blood pressure also changes to meet each specific need. Blood pressure readings could be higher during exercise or while fulfilling everyday tasks. Blood pressure readings are most accurate during restful periods. Blood pressure monitors are available for home use. It is important to have blood pressure tested by a doctor on a regular basis.
