Low blood pressure and high blood pressure are not good for people. Normal blood pressure can make you feel at ease. So, what is the range of normal blood pressure difference?
Normal blood pressure is a prerequisite for blood circulation and flow. Blood pressure is regulated by various factors to maintain normal levels, providing sufficient blood volume to various tissues and organs to maintain normal metabolism. Both low and high blood pressure (hypotension, hypertension) can cause serious consequences, and the disappearance of blood pressure is a precursor to death, indicating that blood pressure has extremely important biological significance.
What is the normal range of blood pressure?
A blood pressure value of less than 120/80mmHg measured for the first time is considered normal blood pressure; The first measurement of blood pressure value of 120-139/80-89mmHg is considered as normal high blood pressure; The first measurement of blood pressure ≥ 140/90mmHg, but less than 180/110mmHg, is considered to be hypertension; If the blood pressure is ≥ 140/90mmHg three times on a different day, it can be diagnosed as hypertension; The first measurement of blood pressure ≥ 180/110mmHg suggests that it is likely to be hypertension. It is recommended to immediately reduce blood pressure and undergo further examination and evaluation at a medical institution. Blood pressure should be closely monitored until it drops to a safe range.
The unit of measurement for blood pressure is millimeter mercury. According to the World Health Organization's guidelines in 1999, blood pressure below 120/80 is the ideal systolic/diastolic blood pressure, below 139/89 is normal blood pressure, 140/90 to 160/95 is elevated blood pressure, and above 161/96 is considered hypertension. Blood pressure allows blood to be transported normally through arteries to the whole body. If blood pressure is too low, it cannot supply blood to the whole body. On the contrary, if blood pressure is too high, it may damage blood vessels and reflect possible abnormalities in the blood or heart.
What factors can affect blood pressure?
1. Height: The taller the body, the greater the pressure on the heart to pump blood, allowing it to flow throughout the body.
2. Age: The younger the age, the higher the metabolic rate, the greater the blood flow, and the heart requires greater pressure to pump blood, which increases with age.
3. Blood viscosity (blood density): The thicker the blood, the greater the pressure the heart needs to pump out the blood.
4. Posture: When standing, blood pressure is higher than when sitting, and when sitting, blood pressure is higher than when lying down. Due to the influence of the principle of gravity.
5. Vascular quality: If blood vessels become narrow, it becomes difficult for blood to pass through, and the heart needs greater pressure to pump out blood.
6. Other factors: mental state, pace of life, personal differences, dietary habits, medication, genetics, weather changes, etc.
After understanding the normal range of blood pressure difference, I have a clear idea in my mind. As for the factors that affect blood pressure, it is also beneficial for us to understand them, so as to prevent the problem of high and low blood pressure.
