At the age of 36, systolic blood pressure of 90~139mmHg and diastolic blood pressure of 60~89mmHg are normal without taking antihypertensive drugs and at rest. For 36-year-olds, normal blood pressure is generally 90~119mmHg systolic and 60~79mmHg diastolic, and normal high blood pressure is 120~139mmHg systolic and/or 80~89mmHg diastolic, and high blood pressure is diagnosed when either systolic or diastolic blood pressure exceeds this value. If you are diagnosed with hypertension, you need to lose weight, reduce sodium intake, supplement potassium salt, eat more fresh fruits and vegetables, stop smoking and drinking, reduce fat intake, exercise properly, keep a good attitude, and take antihypertensive medication correctly under the guidance of your doctor.
