According to a study published by the University of British Columbia, Canada, it reveals that the veins are blue due to an optical effect produced by the skin.

This happens only when the veins are located 0.5 mm below the skin. The white light that is formed by means of all the colors penetrates deeply and produces that bluish effect.

Therefore, the thinner skin, the more blue the tone of your veins.

According to angiologists (specialists in veins and arteries), the blood circulating in the veins is more than blood circulating in the arteries, with the exception of the lungs. This is because it contains less oxygen.
