My face turns red after drinking a little alcohol

Drinking is inevitable at the dinner table and in interpersonal interactions. Drinking has become a behavior in people's daily lives. However, wine contains a large amount of alcohol. Drinking too much will easily allow the alcohol to participate in the blood circulation, thereby promoting capillary dilation. This has led to many people finding that they easily blush after drinking even a little bit of alcohol. People who don't know much about this situation should be familiar with the reasons why they blush after drinking even a little bit of alcohol.

The face is rich in capillaries and the facial skin is relatively thin and transparent, so the effect of alcohol converting into acetaldehyde to dilate blood vessels appears first on the face and slightly lags behind on the body. In addition, some people's palms turn red at the same time as their faces, which is also because the skin on the palms is transparent and rich in blood vessels. The blushing reaction after drinking is caused by a genetic defect in the enzyme that metabolizes alcohol, which leads to a large accumulation of toxic acetaldehyde in the body, causing blood vessels to dilate and causing the blushing reaction. People who blush and drink alcohol are at increased risk of deadly esophageal cancer.

Why does a person's complexion look different after drinking? There are two enzymes in the human body that react to alcohol. One is called alcohol dehydrogenase, which can quickly convert ethanol into acetaldehyde. People who have a large amount of this enzyme in their bodies often experience blushing symptoms within a short time after drinking. The other is called acetaldehyde dehydrogenase. People who blush when drinking only have the former enzyme but not the latter, so acetaldehyde accumulates rapidly in the body and cannot be metabolized for a long time. As a result, their face will be red for a long time. They can only hope that the P450 (a group of oxidases with relatively low specificity) in the liver will slowly metabolize the alcohol they have consumed.

People who don't blush when drinking are the type who hide their true colors. They look normal every time they drink and are always considered to be heavy drinkers. In fact, they are the most tragic because they don't have both enzymes in their bodies, so they don't show symptoms of blushing and can only rely on the liver to slowly break down the alcohol. Therefore, such people are the least clear about their bottom line, are most likely to get drunk, and their livers are most likely to be damaged. Therefore, the fact that one does not blush when drinking does not necessarily mean that he can drink a lot. If people keep urging such a person to drink, the chances of him suffering from alcohol poisoning are extremely high.

There is another type of person who is a barrel drinker. The levels of both enzymes in their bodies are extremely high, and the alcohol in their bodies can be quickly metabolized into sweat and heat and excreted. If you meet such people, you must never compete with them in drinking, otherwise the consequences will be terrible.

The advantage of blushing easily when drinking is that as long as your face turns red and you say that you have reached your limit, most people will not urge you to drink anymore. The alcohol that has been consumed can be broken down by sleeping for a night, so the harm to the human body is not the greatest. If a person does not blush when drinking but lacks two enzymes in his body, he tends to consume more alcohol than he can tolerate, and the burden on his liver will be heavier than he can imagine. Therefore, although blushing easily after drinking is a genetic defect, from another perspective, blushing can also save you from the endless tide of urging you to drink. As long as you don't actively consume alcohol, the harm to your body is actually not very great.
