Blood pressure is measured in millimeters of mercury (mm HG). For a healthy young person around our age, the normal blood pressure is supposed to be less than 140mm Hg over 90mm Hg. The first number (in this case 140), represents systolic blood pressure, which is the pressure in the blood vessels when the heart contracts and the second number (in this case 90), is the pressure between the hearts contractions.
