If you observe carefully, you will find that the veins on some people's hands are often thicker and more obvious, especially when they hold their fists, this change will be more obvious. Some people often have thin skin and tender flesh on their hands, but the veins are hidden deeper. In fact, the veins are the veins in the hands. For doctors, if the veins are more obvious, it will be more convenient for the patient to draw blood or infuse fluids. People with inconspicuous veins may even have a few more veins inserted because the veins are not obvious. I wonder if people with inconspicuous veins have experienced this?

For watches, it is more obvious. In fact, some people think that this is a sign of unhealthy health. Due to the accumulation of too many toxins in the body, such as phlegm, dampness, etc., the blue veins on the hands will become more obvious. Some people will also feel that This is the cause of some diseases, such as high blood pressure, hyperlipidemia and other diseases. In fact, these claims lack scientific evidence, so there is no need to believe too much. So what exactly causes thicker veins? You might as well find out. !

First of all, we should have a certain understanding of blue veins. In fact, they are the vein tissue in our body. For the veins in the hands, their main function is to collect blood in the capillaries of the hands. up, and then flow back to our heart tissue. In addition, except for the hands, almost all our bodies have some venous tissue. In some cases, it is more obvious in the hands and feet, where the skin is relatively weak. In some people, the venous tissue is more obvious. The veins on the hands and feet are often easier to see.

I believe everyone will be curious in life, why their blood is red, but the veins do look blue. Isn’t the blood flowing in the veins red? In fact, I need to remind everyone that, This is actually because our eyes deceive ourselves. In fact, although veins look blue, they are actually affected by the skin of our body. After the light affects the skin, there may be some changes, so it will What causes these veins to look blue is that, without the influence of the skin, the veins are often not blue at all.

If we talk about it in more detail, this is because some blue light is often reflected around our skin, while red light will pass through our skin and will not be reflected by the skin. At the same time, red light is also absorbed by hemoglobin, so there will be these changes. To put it simply, the red light is absorbed by our skin, while the blue light is bounced back, and what appears is blue blood vessels. However, when there is no obstruction by the skin, the blood vessels often look like normal colors, such as It is said that the skin needs to be cut during surgery, and the color of blood vessels is often normal at this time.

So why are some people’s veins more obvious in life, but some people are hard to see? First of all, this may be the difference in personal physique, just like everyone is tall, short, fat and thin in life. We often have some differences in blood vessels. For example, when there is more fat, blood vessels are often blocked by fat, and it does not look too obvious at this time. However, when there is less fat in these parts and the person is thinner, is there any fat? influence, so blood vessels tend to be more obvious.

In life, for those who are more tiring in their daily work and life, such as those who do some physical work for a long time, in order to ensure the muscles of their hands, the blood vessels in their hands will often become thicker in the long run. The blood circulation speed in the blood vessels will also be accelerated. For these people, the veins in the hands are often more obvious. Athletes and people who do regular physical exercise in life often also experience these changes, so don’t be too surprised when you encounter them in life.

Remind everyone that if the blood pressure is not flowing smoothly, if it is affected by blood clots, or if the watch has varicose veins due to venous blockage, the veins will often become obvious, but varicose veins are generally Generally speaking, it is more likely to occur in our legs and feet. When varicose veins appear, patients may also experience leg pain, edema, ulcers, etc. When this happens, we need to seek medical treatment in time. To prevent varicose veins, it is recommended to pay attention to reducing standing or squatting for long periods of time. At the same time, attention should be paid to avoiding prolonged overexertion, which often leads to an increased chance of varicose veins.
