What is the normal range for adult blood pressure?

The normal range for adult blood pressure is defined as being between 90/60 mmHg and 120/80 mmHg. This range is based on standards established by health organizations, which categorize blood pressure readings into categories like normal, elevated, and hypertension.

A reading below 90/60 mmHg could indicate hypotension, which may lead to symptoms like dizziness or fainting, especially if it is significantly lower than an individual's normal blood pressure. On the other hand, a reading of 120/80 mmHg is considered the upper limit of normal; blood pressure at this level is often cited as an ideal benchmark for adult health.

The other provided ranges are not representative of the established normal blood pressure guidelines. They either fall outside the widely accepted definitions or encompass readings that could be indicative of a health condition rather than a normal physiological state.
