Why do people turn red when they're drunk?

Answer 1

something about their blood oxygen level... i think! It also relaxes the blood vessels, allowing more blood to your face, hence the redness... about 90% sure on this one!

Answer 2

Typically, when a person drinks alcohol, her body produces the alcohol dehydrogenase enzyme. The purpose of this enzyme is to convert ethanol (the main ingredient in alcohol) into acetaldehyde--the toxic chemical responsible for those unpleasant hangover symptoms--as well as a harmless acetic acid. While this process usually causes no visible side effects, for some people, a mutation within the alcohol dehydrogenase enzyme prevents the breakdown from occurring. As a result, the toxic chemical identified as acetaldehyde builds up in the individual's body, causing your typical hangover symptoms such as nausea, headaches, drowsiness and light-headedness. However, in addition to these symptoms, the increased amount of acetaldehyde causes capillary dilation. As the body's smallest blood vessels, your capillaries make it possible for oxygen, water and other nutrients to pass through your bloodstream. When capillaries dilate, it can lead to red, raised or itchy skin
Seriously, ignore every single person who commented on this. It's seriously all rubbish. Half of my family are doctors.

Answer 3

Alcohol is a natural blood thinner. Therefore, the more you drink, the thinner your blood becomes. Alcohol also overruns the metabolism making it work harder to rid the body of the toxins. With this, the thinned blood and the body overworking itself brings tiny capillaries to the surface of the skin. It's almost like the blush you see someone get in their face after a hard workout.
