What is normal high blood pressure?

In fact, the normal blood pressure values ​​at each age are different. If the blood pressure is too high, you should be alert to the adverse effects of high blood pressure. Sometimes it can even pose a threat to your life, so you must always pay attention to your blood pressure.

1. The normal values ​​of blood pressure for different age groups make it convenient for modern people to understand their blood pressure in time, detect hypertension in time, and treat it in time. Hypertension has become one of the diseases that endanger modern people.

2. Normal blood pressure is the prerequisite for blood circulation. Blood pressure remains normal under the regulation of multiple factors, thereby providing various tissues and organs with sufficient blood 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. This shows that blood pressure has extremely important biological significance.

3. According to the 1999 World Health Organization treatment guidelines, the diagnostic criteria for hypertension are systolic blood pressure ≥18.7Kpa (140mmHg) and diastolic blood pressure ≥12.0Kpa (90mmHg). This means that the "normal high value" of blood pressure has not yet reached the diagnostic criteria for hypertension and is not hypertension. In this case, if there is no target organ damage and no risk factors, there is no need for treatment.

4. The level of blood pressure is not only closely related to heart function, vascular resistance and blood volume, but also affected by nerves, body fluids and other factors. Blood pressure values ​​will vary with age, season, climate and occupation. Exercise, eating, mood changes, bowel movements, etc. will all lead to increases in blood pressure, while rest and sleep will lower blood pressure.

5. Mental stimulation and emotional changes such as excitement and fear can often lead to a significant increase in systolic blood pressure. Exercise can also significantly increase systolic blood pressure, especially strenuous exercise, which often causes systolic blood pressure to rise to 24.0-6.7 kPa (180-200 mmHg). Blood pressure may drop after exercise stops. An increase in ambient temperature, such as taking a warm bath, can lower diastolic blood pressure, while a decrease in temperature, such as taking a cold bath in winter, can increase systolic blood pressure. People with high blood pressure should pay attention to their diet, as blood pressure increases as people age.
