38 years old, how much blood pressure is normal?

The normal range for 38-year-old blood pressure is 90-139mmHg systolic and 60-89mmHg diastolic.

Blood pressure includes systolic and diastolic pressure. Diastolic pressure is the pressure exerted by blood on the wall of blood vessels during diastole and usually shows a lower number than the blood pressure measurement. Systolic pressure is the pressure exerted by blood on the wall of blood vessels during systole and usually shows a higher number than the blood pressure measurement. If systolic pressure is elevated but diastolic pressure is normal, simple systolic hypertension is indicated. If diastolic pressure is elevated but systolic pressure is normal, simple diastolic hypertension is considered.
