Smoking and drinking are not the most harmful to blood vessels. It is this thing that many people do every day

Blood vessels are distributed in all parts of the body. The blood vessels of the human body are roughly divided into three categories: arterial blood vessels, venous blood vessels and capillaries. They have different roles. One of the common responsibilities is to transport blood, nutrients and oxygen, which plays an important role in the normal activities of the human body. However, with the aging of human body, blood vessels are gradually aging, and the diet, work and rest in life and the external environment will affect the health of blood vessels. < / P > < p > the main component of alcohol is ethanol. Excessive drinking will cause more alcohol in the blood. After decomposition and metabolism, acetaldehyde will be generated. Acetaldehyde is very harmful to human body, especially to the liver and damage liver function. In addition, it will make blood vessels lose elasticity and accelerate the aging of blood vessels. < p > < p > there are more nicotine and tar in cigarettes. These two substances are very easy to cause cancer. They are very easy to adhere to the inner wall of blood vessels. If they accumulate more, they will cause blockage of blood vessels, poor blood flow and cause some cardiovascular diseases. < / P > < p > eating too full is not a healthy eating habit, which will cause harm to the body. Eating too much will increase the burden of digestion and absorption of the body, which is easy to cause damage to some organs; in addition, eating too much, excessive intake of fat, increased blood vessel cholesterol, at the same time, it is easy to cause the increase of vascular epidermal cells, which makes the vascular wall become very thick, so that the elasticity of blood vessels decreases, causing atherosclerosis, and increasing the risk of cardiovascular and cerebrovascular diseases. In the daily diet to ensure that each meal to eat seven full, this is the most conducive to healthy diet. < / P > < p > when the blood vessels of the brain are damaged, it will cause headache. This is because lipid and some other garbage accumulate on the blood vessels, resulting in poor blood flow of the blood vessels, which can not flow to the brain well, causing ischemia and hypoxia of the brain, causing headache. < / P > < p > vascular damage in the brain can not only cause headache due to ischemia and hypoxia, but also cause dizziness. Because of the lack of oxygen in the brain, there will be blurred vision, fatigue, listlessness, dizziness symptoms. These symptoms must be timely medical examination. < / P > < p > in life, holding a posture for a long time or squeezing will often cause numbness of hands and feet. This numbness will be improved by adjusting the posture. However, if the limb numbness often occurs without external stimulation, it may be caused by liver damage. Vascular blockage in the liver will cause liver ischemia and hypoxia, causing limb numbness. This kind of symptom should adjust examination in time, easy to cause liver function to drop. < / P > < p > some people say that the human body needs eight glasses of water every day, which is a more general statement. Specifically, the human body needs about 1000 ml of water every day, which can help the blood circulation and metabolism of the body, reduce the blockage of blood vessels and better protect the blood vessels. < p > < p > fruits and vegetables are rich in vitamins and some minerals, which can enhance the elasticity of blood vessels, prevent vascular aging, reduce the viscosity of blood vessels and the accumulation of garbage toxins in blood vessels, reduce vascular damage, and better maintain the health of the body. Small habits of pregnancy not only affect the health of pregnant mother, but also delay the development of the fetus, don’t ignore
