What is the average normal range for systolic blood pressure?

The average normal range for systolic blood pressure is indeed less than 120 mm Hg. This value is established based on guidelines and definitions from organizations such as the American Heart Association, which classify normal blood pressure as a systolic reading below 120 mm Hg and a diastolic reading below 80 mm Hg. Maintaining blood pressure within this range is crucial for overall cardiovascular health, as elevated systolic pressure can indicate an increased risk for heart disease and other related conditions.

While options that suggest higher thresholds like 130 mm Hg or 140 mm Hg may be seen in discussions about elevated or borderline hypertension, they do not align with the conventional definition of normal systolic blood pressure. Hence, the clear threshold of less than 120 mm Hg remains the recognized standard for normalcy.
