Female low pressure 70 high pressure 90

In daily life, people's bodies have high and low blood pressure standards. The main purpose of measuring blood pressure is to check whether there are problems with high blood pressure or low blood pressure, so everyone must pay attention to it. Generally, women's low blood pressure is 70 and high blood pressure is around 90. You should go to the hospital for a check-up. Because everyone's physical condition is different, the types of high and low blood pressure are also different.

definition

Blood pressure refers to the lateral pressure of blood in blood vessels on the blood vessel wall per unit area, that is, pressure. Since blood vessels are divided into arteries, capillaries and veins, there are arterial blood pressure, capillary pressure and venous blood pressure. The blood pressure usually referred to is arterial blood pressure. When blood vessels dilate, blood pressure drops; when blood vessels constrict, blood pressure rises.

In general, the daily blood pressure fluctuation of normal people is within the range of 2.7-4.0 kPa (20-30 mmHg). Without the influence of antihypertensive drugs, sleep can cause blood pressure to drop by about 20% (more obvious in women). The highest blood pressure point is generally between 9-10 am and 4 pm to 8 pm, and the lowest blood pressure point is between 1 am and 3 am. At this time, the sleep phase often falls in the B and 1v phases. Elderly patients with hypertension spend longer time at the highest and lowest blood pressure points, forming a plateau.

Systolic and diastolic blood pressure

Blood pressure is the pressure exerted on the blood vessel walls when blood flows in the blood vessels. It is the driving force that pushes blood to flow in the blood vessels. When the ventricles contract, blood flows from the ventricles into the arteries. At this time, the pressure of the blood on the arteries is the highest, which is called systolic pressure. The ventricles relax, the elasticity of the arteries shrinks, and the blood continues to flow forward slowly, but the blood pressure drops. The pressure at this time is called diastolic pressure. In other words, the blood pressure formed when the heart pumps blood is the systolic pressure, also called high pressure. Diastolic pressure, also called low pressure, is produced when blood flows back to the heart.

Influencing factors

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 increased blood pressure, while rest and sleep will lower blood pressure.

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.

Hypertension is mainly caused by bad living habits, such as lack of exercise, eating too much salt, smoking, drinking, etc. Among them, eating too much salt is the main factor causing hypertension in my country. However, a bigger concern is people's negligence and lack of awareness about hypertension. About 70% of hypertensive patients are unaware that they are ill, only 14% receive treatment, and less than 10% have their blood pressure effectively controlled. Therefore, early detection and control are very important for the prevention and treatment of hypertension. Early prevention, stable treatment and a healthy lifestyle can control 75% of hypertension and its complications.
