In addition, the size of a person’s alcohol and the body of ethanol dehydrogenase and acetaldehyde dehydrogenase related. Alcohol enters the body or, 90% is broken down into water and carbon monoxide by these two enzymes, of which ethanol dehydrogenase determines the amount of alcohol in the body. The people who drink alcohol and blush because of the lack of ethanol dehydrogenase in the body, resulting in a large amount of ethanol dehydrogenase accumulation with the body, which causes the face and other parts of the blood vessels to dilate, and the phenomenon of blushing.
