Do you know why, after drinking alcohol, your face turns red? Many simply did not pay attention to it. But this can be not only an anatomical feature, but also a sign of an allergic reaction. So why is the face red from alcohol?
Capillaries and blood
Probably everyone knows what happens at a time when blood begins to flow to the face. It takes on a blush and warms up. In some cases, it just blushes. The anatomical cause of this phenomenon is due to the condition of capillaries located in the subcutaneous layers. These are the smallest vessels. Some of the capillaries are located almost immediately under the skin. It is from them that the color of the skin depends. Moreover, with a rapid change in blood flow in the capillaries, the complexion quickly changes.
If the small vessels narrow, the skin becomes paler. With the resumption of blood flow, the face acquires a brighter color. Why does the face redden from alcohol? Everything is simple. When ethanol enters the human body, vasodilation occurs. In addition, the substance causes the gluing of red blood cells. A similar process can lead to blockage of small vessels.
Skin type
It is worth noting that the complexion can also change as a result of individual characteristics of a person. Much depends on the type of skin. For example, blondes and redheads are lighter in color. Even large vessels can be seen through such skin. In such people, pallor changes to blush very quickly and not only when drinking alcohol.
As for swarthy people, then they have a similar process is not so noticeable. Most often, they expand small capillaries located near the surface of the skin.
Factors causing alcoholic redness of the face
Why, when you drink alcohol, your face turns red? There are several factors that affect skin color. When drinking alcohol, not just a blush appears. Often the skin takes on a rich raspberry hue. At the moment, scientists have identified several factors contributing to this phenomenon:
- Allergic reaction to alcohol.
- The classic reaction of blood vessels to alcohol in the body.
- The consequences of chronic alcoholism.
- Congenital intolerance to alcohol, or rather, ethanol intolerance.
Classical vascular reaction
Why is almost everyone blushing from alcohol? When drinking alcohol, ethanol enters the human body. This substance enhances blood circulation. In this case, vasodilation occurs. In addition, ethanol increases blood pressure. The capillaries located under the skin become larger. As a result of a strong blood supply, the skin acquires a red tint.
As shown by numerous studies, the dose of alcohol for the manifestation of a similar effect for each person will be individual.
Is it dangerous
Most often, the blush that appears as a result of drinking alcohol passes on its own and does not cause much trouble to a person. However, in some cases, redness can be very strong and cause discomfort. A sufficiently powerful vascular reaction may indicate weak enzyme functions, due to which ethanol is excreted from the body.
Those with strong redness after drinking alcohol should use such drinks with caution. After all, slow or weakened work of enzymes with a high dose of ethanol can lead to serious intoxication. In the future, this causes the development of more serious complications (oncology of the liver and gastrointestinal tract). Now you know why, when you drink alcohol, your face turns red. However, do not forget about other factors causing a similar reaction.
Congenital Ethanol Intolerance
Why does the face redden from alcohol, even with a minimal dose of ethanol? For some people, such a rare feature as the congenital intolerance of all alcoholic beverages is characteristic. It is worth noting that this feature is often found in representatives of a particular nation. For others, a genetic factor of this kind is extremely rare.
In such situations, when drinking alcohol in humans, the main component of the drink begins to act much faster. Even if a small glass was drunk. The subcutaneous small vessels located in the shoulders, neck and face area expand very quickly and are filled with blood. In this case, a person may experience fever. Often the face and other parts of the body become stained or turn completely red.
Is alcohol intolerance dangerous?
Why does the face red with alcohol stains? Experts have found an explanation for this phenomenon. In their opinion, this is a congenital anomaly. In the human body there are very few enzymes that can remove alcohol from the body. In some cases, there are very few such substances in the liver. Therefore, the reaction can occur almost immediately after drinking even a small dose of alcohol. In case of intolerance, experts recommend avoiding the use of such drinks, since it is very dangerous for humans.
Alcohol with such a genetic deviation can cause the development of a large number of pathologies, including oncological diseases of the stomach, liver, and digestive system organs.
Allergy to alcohol
Why else does the face redden from alcohol and there is discomfort? In some cases, a person develops an allergy to alcohol. On this occasion, there are numerous disputes. After all, alcohol is a "related" fluid for the human body. However, many have such an allergy. In addition, the disease spreads rapidly. It is worth noting that an allergic reaction may occur some time after drinking alcohol. There is no dosage dependence. In other words, the reaction may appear even as a result of moderate alcohol consumption.
The main signs of allergies
The main signs of alcohol allergy include:
- The formation of red spots in the face and neck. In some people, these spots can cover the whole body.
- General redness, as well as itching of the skin, is not ruled out.
- Swelling of facial tissues or swelling of the face.
- Headache that occurs as a result of a rush of blood and the expansion of all blood vessels.
- Blood pressure drops.
- Rapid intoxication even from a small portion of alcohol.
What to do with allergies
Why does the face redden after alcohol, sorted out. It remains to understand how to act with an allergy to alcohol. First of all, a person should abandon the use of strong drinks. With the elimination of the allergen, the well-being of the victim will begin to improve rapidly. However, it is worth considering that ethanol penetrates the blood very quickly. Therefore, experts recommend inducing artificial vomiting. This will clear the stomach.
Do not forget that an allergic reaction can occur not because of ethanol, but because of the additional components that make up the drink: flavoring, coloring, and so on. Cases of the occurrence of such phenomena as a result of drinking cocktails, wines, liquors, tinctures have already been repeatedly noted. To eliminate the signs of allergies, the use of drugs is not recommended. They can not be taken with alcohol. The best option would be to exclude all alcohol.
