Anatomy revealed that the veins stood out were actually superficial veins of human beings. People who often do manual labor, because moving and lifting will increase the pressure on blood vessels, leading to faster blood flow, so blood vessels will become thicker and easier to see. Another situation is that thinner people have whiter skin, so it is easier to see the exposed blue veins.
However, the appearance of the blue veins is not always a good thing. If blue veins appear on the back of the hand, it may be that the body has encountered these problems.
1. Excessive qi and blood
People's impulsive temper leads to excessive qi and blood, which will do some harm to the body in the long run. For example, patients with hyperthyroidism are easily excited, manic and irrational. In the long run, they will speed up the flow of blood and blood, make blood vessels thicker and more exposed.
2. Hyperlipidemia
The components flowing in veins are very complicated. The venous blood flowing inside may contain toxins produced in the process of blood flow and metabolism, and also contain some fat. People with obvious veins on the back of their hands should always observe whether there are abnormal veins directly below the middle of the ring finger and index finger. If there is, it means that the microcirculation in the body is blocked, resulting in poor blood flow, which may be caused by hyperlipidemia.
3. The meridians are blocked
In Huangdi Neijing, it is mentioned that "those who participate in meridians can decide life and death, cure all diseases, and adjust excess and deficiency." People with blue veins on their hands may have a "toxic rash of wet phlegm". If they have a lot of blue veins on their hands, it means that many meridians in their bodies are blocked. If you have chest tightness, shortness of breath, numbness of hands and feet, dizziness and other manifestations for a long time, the situation of hyperlipidemia in the body is more serious. From now on, you should pay attention to the maintenance of blood vessels.
4. Malnutrition
People do not supplement nutrition in time after excessive weight loss or serious illness, resulting in reduced skin fat, thinner back of hand and prominent blue veins.
Friendly reminder: Is it meaningful to have many blue veins and poor health?
The answer is uncertain. The veins stood out should be treated in two. A person without veins standing out may be unhealthy. We need to look at the problem from the position where the blue veins are exposed, such as:
When blue veins appear in thenar, it often implies that leg pain and lower limb joints are affected by rheumatism;
The blue veins on the thumb may be related to the heart, suggesting that the blood supply capacity of the heart is insufficient;
The blue veins appeared in the middle finger, suggesting that the cerebral artery was abnormal and suspected arteriosclerosis;
However, there is another situation: whether there are many blue veins on the back of the hand depends mainly on what kind of work they are engaged in. Even if you have a lot of veins standing out on your hands, you can't judge whether you are healthy or not.
If you are a sedentary white-collar worker in the company, it is not easy to see the blue veins on the back of your hand because of the fat on your hands. Even if they have three highs, we can't see the veins standing out on their hands.
People who often do manual labor are prone to blue veins because of the high frequency of hand use, the blood flow rate in capillaries increases and blood vessels dilate. Therefore, the bulge of the veins stood out has nothing to do with one's own health, let alone a person with many veins stood out. It can't be said that he is in poor health and needs further diagnosis through physical examination.
