The cause of alcohol on the face starts with two enzymes in the human body: one is ethanol dehydrogenase; the other is acetaldehyde dehydrogenase. When alcohol enters the body, it is converted into acetaldehyde under the action of ethanol dehydrogenase, and acetaldehyde is converted into acetic acid under the action of acetaldehyde dehydrogenase, and finally acetic acid is discharged from the body. Therefore, when acetaldehyde cannot be metabolized to acetic acid, it will accumulate in the body, making people appear red, and at the same time acetaldehyde plays a role in damaging DNA in the human body. Therefore, drinking and blushing can lead to a high risk of cancer, especially esophageal cancer, which is the literature statistics show that people who drink and blush have a higher chance of getting esophageal cancer than people who do not drink and blush, while people who drink and blush also have serious problems with high blood pressure, so drink appropriately.
