What is considered the normal range for adult blood pressure?

The normal range for adult blood pressure is defined as approximately 120 over 80 millimeters of mercury (mmHg). This measurement signifies the pressure in the arteries during the contraction of the heart (systolic pressure) and the pressure in the arteries when the heart rests between beats (diastolic pressure).

A blood pressure of 120/80 mmHg is often referred to as "optimal" or "ideal" blood pressure, as it is associated with a lower risk of cardiovascular disease and other health complications. Maintaining blood pressure within this range is important for overall heart health and is emphasized in clinical guidelines for adults.

Other values such as 100/60 mmHg may indicate hypotension or lower than usual blood pressure, which can cause symptoms like dizziness or fainting. A reading of 130/90 mmHg may be considered prehypertensive, indicating a potential risk of developing hypertension, while 140/80 mmHg can be classified as stage 1 hypertension, which comes with increased risks for adverse health effects if not managed properly. Thus, 120/80 mmHg is recognized as the standard for what is considered healthy blood pressure for adults.
