Why do you blush after drinking?

Some people will blush after drinking, this is because the blood circulation of physical strength is accelerated, and there are more hair blood vessels on the face, which are red when the blood accelerates, so they will blush.

After drinking. Under the influence of alcohol.

The body's blood circulation is increased (this is why the whole body feels hot after drinking).

The face has more hairy blood vessels, and it is red when the blood accelerates.

Because you drink red wine, if you drink white wine, it will turn white, and if you drink beer, it will not change color.

Causes of flushing after drinking. Facial ** flushing is caused by transient vasodilation under the skin, and the main cause is caused by acetaldehyde, a phenomenon known in medicine"Drinking and red-faced"。Acetaldehyde dilates the capillaries in the face, which is what causes blushing.

Those who blush quickly convert ethanol to acetaldehyde, which means they have a highly efficient enzyme called alcohol dehydrogenase. In addition, there is also an enzyme - acetaldehyde dehydrogenase, people who drink alcohol and blush only have alcohol dehydrogenase and no acetaldehyde dehydrogenase, so the body accumulates acetaldehyde quickly and the metabolism is slow, so there will be a face like Guan Gong.

Some scholars believe that it is an allergic reaction to the blood vessels of the face. A small number of patients with post-alcohol red face feel hot in the face after absorbing ethanol for 5 10 minutes, and at the same time, the face or whole body ** flushing, throbbing headache, dyspnea, nausea, vomiting, sweating, thirst, chest pain, low blood pressure. Symptoms such as dizziness, blurred vision, and impaired consciousness are considered to be drunk, which is medically called"Acetaldehyde syndrome"This is because the oxidative metabolism of ethanol causes a significant increase in the level of acetaldehyde in the blood.

The facial capillaries are abundant, while the face ** is thin and transparent, so the effect of alcohol converted into acetaldehyde to dilate blood vessels first appears on the face, while the body lags slightly. In addition, some people's palms turn red in sync with their faces, because their ** is transparent and rich in blood vessels. What we found was that something was wrong with the way the body metabolized alcohol, which was acetaldehyde.

Under normal circumstances, we drink alcohol, whether it is liquor or beer, it is alcohol, relatively speaking, the alcohol content of liquor is a little higher, some liquor alcohol content is more than 60 degrees, for beer, the alcohol content may be slightly lower, and some beer alcohol content is less than 10 degrees. When the alcohol in alcohol enters the body, it is converted into acetaldehyde by an enzyme. Such an enzyme is called alcohol dehydrogenase.

Subsequently, such acetaldehyde, under the action of acetaldehyde dehydrogenase, forms acetic acid, which in turn will be decomposed into water and carbon dioxide.

Some people are allergic to alcohol, and people with this constitution will have a red face after drinking, and this kind of person is actually not allowed to drink, which is likely to lead to alcohol poisoning.

This may be an allergic reaction to alcohol, or it may be a reaction of his body to ingesting alcohol, or it may be a gradual increase in the head after drinking, causing redness on the face.

Because of the dilation of blood vessels, the ethanol in alcohol can dilate the capillaries in the face, and the blood vessels will appear blushing when they are dilated.

Drinking alcohol flush is due to a lack of acetaldehyde dehydrogenase in the body.

People's Daily Online once introduced in a report that after people drink alcohol, the alcohol is first catalyzed by ethanol dehydrogenase and turned into acetaldehyde; Acetaldehyde then becomes acetic acid under the action of acetaldehyde dehydrogenase; Finally, acetic acid is involved in multiple metabolic pathways in the body, being converted into carbon dioxide and water and excreted from the body.

Some people "get on their faces" as soon as they drink alcohol, because after alcohol is metabolized into acetaldehyde, it is difficult for acetaldehyde to be decomposed into acetic acid due to the lack of acetaldehyde dehydrogenase in their bodies, resulting in a large accumulation of acetaldehyde, resulting in blushing.

There is also a type of person whose face turns white after drinking alcohol, which is due to the lack of both alcohol and aldehyde dehydrogenase. If the human body cannot excrete alcohol in time after ingestion, it will lead to a decrease in the oxygen-carrying capacity of the blood, and the symptom is that the face is pale, and such people should be more cautious about drinking.

1. Facial flushing is caused by temporary subcutaneous vasodilation, mainly caused by acetaldehyde, which is called "drinking flushing" in medicine. Acetaldehyde has the function of dilating the blood vessels of the capillaries, and the dilatation of the capillaries in the face is the cause of the blushing. People who drink alcohol and blush only believe that there is ethanol dehydrogenase and no acetaldehyde dehydrogenase, so the body quickly accumulates acetaldehyde and cannot be metabolized.

2. It is an allergic reaction to the blood vessels of the face. A small number of patients with alcoholic flushing feel burning on the face within 5 to 10 minutes of ethanol absorption, and at the same time, the face or the whole body ** has symptoms such as flushing, throbbing headache, dyspnea, nausea, vomiting, sweating, thirst, chest pain, low blood pressure, syncope, blurred vision and confusion, then people think that they are drunk, which is called "acetaldehyde syndrome" in medicine, which is caused by the significant increase in blood acetaldehyde levels caused by ethanol oxidative metabolism.

3. The capillaries on the face are abundant, and the face is relatively thin and transparent, so the effect of converting alcohol into acetaldehyde to dilate blood vessels is the first to appear on the face, and the body is slightly lagging behind. In addition, some people's palms turn red in sync with their faces, and the reason is that their palms are transparent and rich in blood vessels.
