Blue veins under skin: Have you ever noticed that, why the veins appearing under our skin often look blue in color? Whereas we all know that the blood is red in color. Then what is it that shows these nerves blue? Is blue bleeding somewhere in our body? Many people are confused about this. But the answer behind it is neither a disease nor any secret. Rather it is a very interesting thing of science. Therefore, today we will explain this interesting science in common language.
First of all, clean one thing, the blood flowing in our veins is not blue. Blood is always red in color, whether it is rich in oxygen or oxygen free. The only difference is that oxygen blood is bright red, while oxygen -free blood is slightly darker red. Then why does the veins look blue?

What is the cleverness of skin and light?
When sunlight or bulb light falls on our skin, all the colors present in it collide with the skin. After this, the skin absorbs some colors and sends some back. So when we look at the veins, most of them reach our eyes and we feel that the veins are blue.
What is the illusion of the depth of the veins?
The veins under our skin are at a slight depth. On seeing the things present in the depth, their color often looks different to our eyes, because the path of light reaching it is longer. This can also make the veins look blue, while in reality their color is not the same.
Eyes and mind games
Our eyes and minds together do a kind of “color processing”. Instead of the veins, the color of the surrounding skin and the direction of the light, they all indicate to the brain that the vein is blue.
Actually, it is an optical Illusion.
Are blue veins a sign of a disease?
Blue veins are completely normal. If the veins look very bulging, pain or swelling, then consultation with a doctor is necessary.
There is no need to be afraid to see the blue veins. It is a small cleverness with science and light eyes, not a sign of something wrong in the body. The next time someone asks “Brother, why do the veins look blue?” So now you will not only be able to answer, but will also be able to tell the fun aspect of science.
