The blue veins on some people's wrists look terrible, but others are hard to see. Why?

The blue veins on some people's wrists look terrible, but others are hard to see, which is related to obesity, skin color and blood vessel thickness.

First, it has something to do with human skin. The blue veins are actually the blue color that the blood in the blood vessels shows through the skin. The blue veins are blue. If people's skin is white, the blue veins will be more obvious visually. But if your skin color is black, it will cover the color of the blue veins, because the difference of skin color makes the blue veins less obvious.

The second is related to weight, that is, people's fatness. The fat body covered the veins stood out like a piece of cloth. Some people are fatter and have more meat on their bodies, indicating that the cover is thicker. Then the blood vessels are covered with fat, and the veins in this part of the blood vessels will not be obvious. On the contrary, thin people have fewer blue veins and look more obvious.

The third is related to the amount of exercise. Some people often exercise, which will speed up the blood movement and circulation, so the blood circulation will be smoother, there will be more muscles on the body, and the corresponding veins, that is, veins, will be more obvious. If you are a person who does less exercise, it may not be so obvious.

Another reason is caused by disease factors. The symptom of varicose veins is that the blood vessels in the body protrude on the body surface, which looks like veins protruding from the surface, but it is actually caused by slow blood circulation.

Therefore, we don't have to worry too much about the amount of blue veins on our skin, but we need to pay attention to them when the blue veins are blue and we are unwell.
