Why do you blush when you drink alcohol? Why do you blush when you drink alcohol?

I also blush because we have a part of our genes missing, so we lack an enzyme in our body that breaks down acetaldehyde into carbon dioxide and water, and alcohol is broken down by alcohol enzymes to form acetaldehyde, which has the effect of dilating blood vessels, so when we drink alcohol, our faces are red.

But acetaldehyde is harmful to the body, because acetaldehyde can only be excreted through the kidneys, so it is better for people like us to drink less!

Many people blush after a little bit of drinking when they drink, what is the reason for this? Most people think that drinking alcohol and blushing is because the amount of alcohol is not good, but is that what does that mean? Let's take a look.

After research, it has been found that people who blush when they drink alcohol should not be too greedy.

The phenomenon of blushing occurs after alcohol enters the human body, this is because acetaldehyde is a harmful substance to the human body, and there is an enzyme in the human body that can break down acetaldehyde. Moreover, some people who don't drink alcohol generally have a weak decomposition function of this enzyme, so they will blush when they drink alcohol.

If telangiectasia occurs on the face, acetaldehyde also has the effect of dilating capillaries, which will cause some people to blush. That is, people who drink alcohol and blush can quickly convert ethanol into acetaldehyde, and such people have a highly efficient enzyme alcohol dehydrogenase, but let's not forget that there is also an enzyme, acetaldehyde dehydrogenase. Only the former enzyme does not have the latter enzyme, so it can only accumulate acetaldehyde resin quickly, and it cannot be metabolized for a long time, so it will be red for a long time.

Drinking blushing is often referred to as "upper face", but it is actually an alcoholic blush reaction, also known as Asian blush syndrome. It refers to the local or systemic reddening reaction caused by the degradation of acetaldehyde and metabolic by-products after alcohol metabolism after drinking. The main chemical component of alcohol is ethanol, which is quickly absorbed into the bloodstream and then metabolized by the liver when it is drunk into the stomach.

The liver metabolizes ethanol and involves two key enzymes: one is alcohol dehydrogenase and the other is acetaldehyde dehydrogenase. Drinking alcohol and blushing is likely to cause harm to the body, because the human body needs two enzymes to metabolize alcohol after drinking, these two enzymes are alcohol dehydrogenase and acetaldehyde dehydrogenase, if these two enzymes are sufficient, then you will not blush, but if you lack one of them, it will cause blushing.

Acetaldehyde is harmful to the human body and needs to be metabolized by the liver, which increases the burden on the liver. If you do this in the long run, it will be bad for your health. After drinking alcohol, the enzyme acetaldehyde dehydrogenase in the human body can convert alcohol into acetaldehyde, then into acetaldehyde, and finally into carbon dioxide and water, acetaldehyde is a vasodilator, but also a toxic substance.

It can cause people to have palpitations, chest tightness and discomfort, flushing, heartbeat, shortness of breath, etc. In fact, everyone blushes when they drink, but some people are obvious, and some people are not. It is said that drinking and blushing is because it is affectionate, but it is not.

Drinking blushing is because of the reaction of the blood, and drinking blushing is because the alcohol is following the blood. Drinking alcohol is most afraid of purple face, this kind of people have liver function problems, and alcohol is going to the liver, so it is best not to drink alcohol in the future. Most people who drink alcohol and blush have a genetic defect in abnormal alcohol metabolism!

The Chinese population has the highest rate of alcohol metabolism gene defects in the world, drinking alcohol increases the risk of n kinds of cancer, you must be moderation, it is best not to drink! No matter what kind of alcohol it is, the appropriate amount of alcohol to drink is "0". Drinking alcohol flush is an alcohol allergy, drinking alcohol to the stomach heart and lung reception is poor, some people feel on the face, some people feel chest tightness, panic, fever, sweating, according to this situation to drink less or stop drinking, take a break and drink a little boiling water or dessert drinks.

The reason why you blush when you drink alcohol is because it is an alcoholic blush reaction, which is a phenomenon that occurs after drinking alcohol. Half of Asians will have this Asian red face after drinking, but it is rarely seen in other races, this is a genetic trick, Asians have mutations in the acetaldehyde dehydrogenase gene, resulting in deficiencies in the body, but European and American people have very few mutations, and there are relatively more acetaldehyde dehydrogenase.

Chemical reaction formula for drinking:

Alcohol dehydrogenase ——— acetaldehyde dehydrogenase.

Wine (ethanol) – acetaldehyde ——— acetic acid.

ch3ch2oh———c2h4o———c2h4o2

The catabolism of alcohol in the human body mainly depends on two enzymes in the liver's enzyme system: alcohol dehydrogenase and aldehyde dehydrogenase.

Alcohol dehydrogenase removes two hydrogen atoms from an alcohol molecule, causing ethanol to decompose into acetaldehyde. Acetaldehyde dehydrogenase can remove the two hydrogen atoms in acetaldehyde, so that acetaldehyde is converted into acetic acid, and finally decomposed into carbon dioxide and water.

If the human body has these two enzymes, it can break down alcohol more quickly, and the central nervous system is less affected by alcohol. In the human body, alcohol dehydrogenase is present in almost equal amounts. However, there are more people who lack acetaldehyde dehydrogenase, and the lack of acetaldehyde dehydrogenase makes alcohol not completely decomposed into water and carbon dioxide, but continues to remain in the body with acetaldehyde, causing people to have drunken symptoms such as nausea and vomiting, coma and discomfort after drinking.

Therefore, people who are not good at drinking alcohol and drink below a reasonable standard are considered to have insufficient or complete deficiency of acetaldehyde dehydrogenase. For people who are good drinkers, drunkenness can also occur if they drink too much and too quickly, exceeding the ability of the two enzymes to break down.

Drinking tea after drinking is not a good habit. Because after drinking, 80% of the alcohol is gradually broken down into water and carbon dioxide by the liver and excreted from the body, thus acting as an anti-hangover, and this decomposition generally takes 2 to 4 hours. If you drink tea immediately after drinking, the acetaldehyde in the wine will be quickly excreted from the body through the kidneys, causing damage to the kidneys and reducing kidney function.

At the same time, drinking too much tea and drinking too much water will also increase the burden on the heart and kidneys, which is even more unfavorable for coronary patients with hypertension and angina. Therefore, it is best to eat some fruits such as pears and watermelons after drinking.
