What is the normal systolic and diastolic blood pressure range for healthy adults?

• A. Systolic 90-119; Diastolic 60-79
• B. Systolic 100-139; Diastolic 60-89
• C. Systolic 110-129; Diastolic 70-79
• D. Systolic 120-129; Diastolic 80-89

Answer: (A)

Normal blood pressure in healthy adults is usually defined as a systolic reading under 120 mmHg and a diastolic reading under 80 mmHg. A range of 90-119 systolic and 60-79 diastolic sits squarely inside that normal window, reflecting typical, healthy arterial pressures when the heart is at rest between beats and during contraction. Values approaching 120/80 start moving toward elevated or borderline hypertension categories, which is why the other ranges are not considered normal. Keeping readings within 90-119 / 60-79 helps minimize cardiovascular risk in healthy individuals.
