What is the normal range for adult blood pressure?

The normal range for adult blood pressure is considered to be around 120/80 mmHg. This value is recognized by numerous health organizations, including the American Heart Association, as the ideal target for healthy adults. Blood pressure is measured in millimeters of mercury (mmHg) and consists of two numbers: systolic pressure (the first number, indicating the pressure in the arteries when the heart beats) and diastolic pressure (the second number, reflecting the pressure in the arteries when the heart is at rest between beats).

A reading of 120/80 mmHg is seen as optimal because it indicates that the heart is functioning efficiently without unnecessary strain on blood vessels. Values significantly above this range can suggest hypertension, while much lower values may indicate hypotension, both of which can lead to health issues if unaddressed.
