What is the normal range for adult blood pressure?

The normal range for adult blood pressure is typically established as 90/60 mmHg to 120/80 mmHg. This range indicates a healthy blood pressure level that reflects optimal cardiovascular function for most adults. The systolic value (the first number) ideally falls between 90 and 120 mmHg, while the diastolic value (the second number) should be between 60 and 80 mmHg. Blood pressure readings within this range suggest a balanced cardiovascular state, reducing the risk of conditions such as heart disease and stroke when maintained over time.

In contrast, the other options present ranges that either reflect hypotension (too low) or hypertension (too high) for adults. Recognizing the correct normal range is crucial in clinical practice for diagnosing and managing various health conditions effectively.
