Not long ago, the Internet spread: “drinking red people drinking is suicide”! A time to cause a lot of drinking blush a family of panic, and at the same time seems to give those who drink a thousand cups are not blushing alcoholic friends to find the basis for reckless drinking, booze. Is this true? The redness and non-redness of the face after drinking is mainly determined by two aspects. On the one hand, it is related to the drinker’s sensitivity and responsiveness to alcohol. When alcohol enters the body, the blood vessels dilate and become congested within a short period of time, which becomes “red” on the face. On the other hand, it is also related to the ability of individual drinkers to metabolize alcohol. Alcohol in the body is mainly metabolized by the liver (the specific principle is not discussed here), and the ability to metabolize alcohol varies greatly from person to person. Drinking the same amount of alcohol, people with a strong liver metabolism have a relatively short time to stay in the body, and the amount of alcohol accumulated is relatively small, so the possibility of blushing is small or the degree of blushing is light; conversely, alcohol stays in the body for a relatively long time, and the accumulation of relatively more, causing the possibility of blushing is large or the degree of blushing is relatively heavy. But in any case, the redness of the face after drinking is neither a criterion for judging whether you can drink, nor a basis for judging how much alcohol you can drink. As for saying: “Drinking is suicide for people who drink and blush”, it is even more unscientific. In everyday life, regardless of whether the drink is red or not, healthy drinking is the key. People who have the habit of drinking, even if they do not blush after drinking, healthy adult men should ensure that the amount of alcohol consumed in a day does not exceed 25 grams (equivalent to 750 ml of beer, or 250 ml of wine, or 75 grams of 38 degree white wine, or 50 grams of high white wine); healthy adult women should ensure that the amount of alcohol consumed in a day does not exceed 15 grams (equivalent to 450 ml of beer, or 150 ml of wine ml, or 50 grams of 38-degree white wine), which is good for health, and is detrimental to health once this amount is exceeded. It is worth reminding people that we never advocate those who do not have the habit of drinking alcohol to actively promote their health by drinking alcohol.
