Blood pressure is the pressure on the blood vessel wall when blood flows in the blood vessel. Blood pressure of different blood vessels has different names, namely arterial blood pressure, capillary blood pressure and venous blood pressure, and this common blood pressure refers to arterial blood pressure in systemic circulation.
Generally speaking, the three elements that make up blood pressure are heart, blood vessels and blood. When our heart is in a state of nervous contraction, our blood will gush out and form a certain lateral pressure on the blood vessel wall. This pressure is called high pressure. When the heart relaxes and relaxes, the inner wall of our blood vessels is more elastic, and the blood vessels contract, which will form low pressure. When the blood pressure is too high, it will form diseases such as arteriosclerosis, such as cardiovascular and cerebrovascular diseases, while when the blood pressure is too low, it is easy to feel dizzy and weak. Therefore, we should always check our blood pressure.
According to the professional display, the normal blood pressure of human body is between 120 and 80 mm Hg. But generally speaking, human blood pressure is slightly higher at this value.
When we measure blood pressure in a clinic or a hospital, when the blood pressure index is greater than 140 to mmHg or measured at home, the blood pressure is greater than 135 to 85 mmhg, which indicates hypertension.
When we take blood pressure at home, we usually take 1 2 times, so don't take it again. Keep a relaxed mood, use a sphygmomanometer when measuring, so that the arm measuring blood pressure can keep balance with the heart, thus measuring accurately and slowly. When blood pressure rises, you should go to the hospital for treatment and seek the help of a doctor.
You know, three out of every ten people will suffer from high blood pressure. After suffering from hypertension, the medication we can take is antihypertensive drugs. At present, there are 4 ~ 5 commonly used antihypertensive drugs, including diuretics, β receptor antagonists, calcium channel blockers (CCB), angiotensin converting enzyme inhibitors (ACEI) and angiotensin Ⅱ receptor antagonists (ARB).
These antihypertensive drugs have distinct effects and obvious effects. However, with the help of doctors, it is necessary to use drugs that suit you correctly and reasonably in order to keep blood pressure within a reasonable range. In addition to using antihypertensive drugs, we should also correct our lifestyle and start from daily life to lower blood pressure better.
1, weight control
Studies have shown that for obese people, the frequency of hypertension is much higher than that of normal people. So we should control our weight at this time. Generally speaking, the body mass index is normal between 18.5-23.9. Moreover, every time we lose 1 kg, our blood pressure will drop by 4 mm Hg. Only by controlling weight can we reduce the cholesterol content in the body, thus lowering blood pressure.
Step 2 exercise more
Long-term exercise will not only make people have a good mental state, but also play an important role in our physical and mental health development. Hypertensive patients should increase some soothing aerobic exercise. At this time, you can increase your exercise by walking slowly and playing Tai Ji Chuan, and increase your heartbeat and breathing frequency, so as to make your heart stronger, exercise your muscles and prevent arteriosclerosis. This long-term physical exercise has a strong control effect on our hypertension.
Step 3 quit smoking and drinking
We all know that smoking and drinking are extremely harmful to the human body, including cigarette packages that say smoking is harmful to health, but some people still disagree. Smoke contains a lot of nicotine, which can raise blood pressure, and carbon monoxide in smoke can also raise blood pressure by combining with protein. In addition, after drinking a lot, blood vessels and arteries will harden, leading to an increase in blood pressure. From this point of view, we should give up smoking and drinking. Only in this way can we lower our blood pressure and make our bodies healthier.
Step 4 keep a good mood
Being in a bad mood can also raise blood pressure. When we are badly stimulated, neuropsychiatric factors will cause the disorder of higher nerves, which will enhance the response of the central nervous system that regulates blood pressure, thus increasing the secretion of active substances such as catecholamines in blood vessels and raising blood pressure. Therefore, we should keep an optimistic and positive attitude and a good mood at all times. After all, great joy and great sorrow will do harm to the human body.
5, less salt and more potassium
Through a large number of clinical experimental data, it is proved that the important factors of many people suffering from hypertension are eating habits and eating more sodium salt. According to statistics, every time 1g sodium salt stays in the human body,11g water and1g sodium salt will be used to form physiological saline and stored in the body, which will lead to the increase of water in blood vessels and the excessive pressure on blood vessel walls, thus resulting in hypertension. Therefore, it is necessary to reduce the intake of sodium salt and keep the intake of salt below 5 grams per day. At the same time, increasing the intake of potassium and eating more foods containing potassium can not only reduce the salt content in the body, but also relieve the tension of blood vessels.
6, a reasonable diet
Eating more fruits and vegetables and coarse grains will help lower blood pressure. For patients with hypertension, the diet needs to eat some low-fat and low-salt foods, and it should be quantified regularly, eat less irritating foods and eat more light ones. Using some low-fat foods can reduce the cholesterol content in the body, thus reducing high blood pressure. We should also use some low-salt foods, such as apples, which have high potassium content and can be combined with sodium salt in the body to discharge sodium salt, which is extremely beneficial to the body.
The above six auxiliary methods play a very important role in lowering blood pressure. Many times, blood pressure is not just a temporary increase, but a long-term accumulation. Therefore, it is necessary to start from daily life, regulate diet, exercise more, keep a good mood, and quit smoking and drinking, so as to be beneficial to physical and mental health.
