Some people have thick blue veins on the back of their hands, while others can't see them. What is the reason?

There are many veins in the body, both on the back of hand and instep. This vein is actually the jadeite tendon we usually see. Some people have obvious jadeite ribs on their backs, which are thick and have many shapes. You can see them clearly even behind their feet. However, some people must be very bright and clean, and carefully observe the existence of jade tendons.

From a reasonable point of view, physical and mental health has nothing to do with health. In fact, the jadeite tendon in the hand is a vein, which is mainly used for blood flow. Veins are often so clear, the main reason is that the oxygen content in venous blood vessels is relatively low, which is very easy to see under the illumination of light source, showing blue and blue.

Some of the veins in everyone are too thick, but some people can't see it. In fact, this has something to do with people's figure and different skin conditions. If a person's skin is white, the pulse is obvious, because the venous blood vessels are under the skin and the skin on the back of the hand is very thin, so it is very easy to see. Some people's skin is dark brown, so the veins in their hands are not so easy to see.

If people are thinner, their arms will have less body fat, so their veins will look more prominent. If a person is too obese, there will be more body fat on his arms, his hands will look chubby, and veins will naturally be hard to find.

People who exercise regularly or like sports will have a faster heartbeat, stronger bounce and more capillaries in their limbs. In this case, the more prominent the emerald tendon on the back of the hand, it means that the human body may be healthier, which means that your body has got some exercise, and moderate exercise is very beneficial to the physical and mental health of the human body.

In summer, the capillaries on the back of the hand look obvious, which is a normal phenomenon of the human body. Due to the high temperature weather, capillaries expand to generate heat, no matter whether the blue veins on the back of the hand are obvious or not, there is nothing too good or too bad, because it does not mean whether a person is healthy physically and mentally.
