The normal blood pressure range for men is systolic <120 mmHg and diastolic <80 mmHg. The standard for normal blood pressure in adults is systolic <120 mmHg and diastolic <80 mmHg. There is no difference in the standard for normal blood pressure in adults between men and women, and the range of normal blood pressure in men can be determined by referring to the standard for blood pressure in adults. For hypotension, there is no clear diagnostic criteria, often referring to systolic blood pressure <90mmHg and diastolic blood pressure <60mmHg. However, some young people are weak, systolic blood pressure can be below 90mmHg and diastolic blood pressure below 60mmHg, without any symptoms of inadequate perfusion. Symptoms such as dizziness, dizziness, weakness, myocardial ischemia, oliguria, etc. are also considered normal. It is recommended to increase sports forging, high salt diet, strengthen physical fitness, and try to keep blood pressure above 90/60mmHg.
