Nothing - it's when your veins aren't blue that there's a problem.
Veins appear blue because of the way light interacts with the skin. The blood in your veins is actually red, but the way light is absorbed and reflected by your skin makes them appear blue.
The veins under your tongue don't turn blue, they just are blue. Blood is blue in color before it meets air; once it has it turns blood red.
The Veins Will Turn Blue
Veins appear blue when they are close to the skin's surface because of the way light interacts with the skin. The skin absorbs most of the light that hits it, but blue light is able to penetrate deeper into the skin and is reflected back to our eyes, making the veins appear blue.
Blue Veins was created in 1999.
Blood is not actually blue in veins. The misconception that blood is blue in veins comes from the way light interacts with our skin, making veins appear blue. In reality, blood is always red, whether it is in the veins or arteries.
the color of your veins is blue
the veins are blue.
Blood is blue in your veins!
A blood seems blue in veins because when a blood is in veins they are low in oxygen and therefore look blue. When they get oxygenated, they become red and are carried by the artery.
Not at all. Veins should mostly always be blue, un-oxygenated blood has a deeper purple-ish tint to it, through the skin we see it as a blue color. Arteries are slightly too deep for us to view, though we can feel our pulses through them
No, it is not bad. Every one has the same kind of veins in their hands. This is a normal thing to have.
