The normal range of blood pressure in young people is around 120/90 mmhg. Blood pressure is primarily the pressure exerted on the side walls of blood vessels during blood flow. In normal adults, the normal value of blood pressure measured in a quiet state is 120/90 mmhg. Hypertension is diagnosed after the average of three measurements taken on a different day is ≥140/90 mmhg. Blood pressure tends to increase with age, and the increase in systolic blood pressure is more pronounced than the increase in diastolic blood pressure. Meanwhile, women’s blood pressure is slightly lower than that of men of the same age during menopause. Normally, the arterial blood pressure in the upper arm of both sides of a normal person will have a certain difference, and the difference ranges from 5 to 10 mmhg. In addition, normal blood pressure fluctuates between daytime and nighttime, mostly at its lowest level at 2-3 a.m., with peaks occurring at 6-10 a.m. and 4-8 p.m. If symptoms of blood pressure abnormalities occur, the blood pressure will fluctuate. If symptoms of abnormal blood pressure occur, it is recommended to go to the hospital in time for early treatment.
