Why are people who blush after drinking particularly good at drinking?

Many people mistakenly believe that blushing is caused by alcohol, but this is not the case. After alcohol enters the body, it is first converted into acetaldehyde by alcohol dehydrogenase, and acetaldehyde has the function of dilating capillaries, causing the face to become red as soon as it expands.

However, there is another enzyme in the human body called acetaldehyde dehydrogenase. People who blush after drinking only have alcohol dehydrogenase but no acetaldehyde dehydrogenase. Therefore, acetaldehyde accumulates rapidly in the human body but cannot be metabolized, so a long-term blush occurs.

However, people who often drink alcohol also have experience. Generally, the redness will fade after a few hours. This is due to the cytochrome enzyme in the liver slowly converting acetaldehyde into acetic acid, which is slowly metabolized. dropped.

In short, drinking is related to people’s physical fitness. Blushing doesn't mean you're particularly good at drinking.
