The correct answer is
Optimal blood pressure is less than 120/80 mm Hg, according to the National Heart, Lung and Blood Institute (NHLBI). The exact level that marks low blood pressure, however, differs from person to person. The body uses several mechanisms to regulate blood pressure. It can expand or constrict blood vessels; change the amount of blood pumped from the heart; or change the amount of blood pumped through blood vessels. These mechanisms help blood pressure return to normal after changes brought on by eating, exercise, sleep, or position. Although chronic low pressure may be a sign of disease, it also can indicate good physical conditioning. Athletes often have low blood pressure.
