What is considered normal blood pressure for an adult?

The figure of 120/80 mmHg is regarded as the standard reference point for normal blood pressure in adults. This reading is a benchmark established by organizations such as the American Heart Association. The first number, known as systolic pressure, represents the force of blood against the artery walls when the heart beats, while the second number, or diastolic pressure, indicates the pressure when the heart is resting between beats. A systolic value of 120 and a diastolic value of 80 indicate a healthy and well-functioning cardiovascular system, suggesting that blood is flowing efficiently without causing undue strain on the heart or blood vessels.

Blood pressure readings that fall outside this range can indicate varying levels of hypertension or hypotension, which can affect overall health. Values higher than 120/80 may suggest prehypertension or high blood pressure, while significantly lower values could suggest hypotension, which may lead to insufficient blood flow to organs and tissues.
