In cold weather, down jackets and thick coats can be seen everywhere on the street. In restaurants and restaurants, the phenomenon of drinking wine while eating has gradually increased. People often hear people say, “Drinking a bar can be warm and cold, and cold!†. "The more you drink, the hotter you drink, the more you drink, the colder you get." This is a long-disseminated discourse and concept. However, as everyone knows, drinking in the winter can not only not warm the effect of cold, but will drink more and more cold, and then trigger some of the body problems.
The more you drink, the colder you drink. Why is this?
People have this kind of experience. The higher the alcoholicity, the hotter the body is after drinking alcohol. We will mistakenly believe that the wine itself contains a lot of calories. In fact, the main components of alcohol are alcohol and water. The amount of heat contained in alcohol itself is extremely limited. According to the measurement, each gram of ethanol can release about 7,000 calories in the human body. If the body drinks about one or two white spirits, the calories it emits is only equivalent to 25 grams of oil or The heat generated by 50 grams of sugar can be seen to have a negligible effect on human body temperature.
Drinking hot feelings,
how did it get here
When alcohol enters the body, the absorption and metabolism of alcohol begin. Alcohol itself and its metabolites, such as acetaldehyde, have the effect of dilating blood vessels, thereby allowing the capillaries on the human skin to expand and the blood circulation to accelerate. As a result, the heat in the human body will be quickly released to the body surface, and the body will feel the body heat. In addition, alcohol and its metabolites also have a certain level of anesthetic effects on the central nervous system, which reduces the sensitivity of the skin to outside temperatures.
However, it is worth noting that the loss of heat inside the body is only a short period of time. In other words, the “warmth†after drinking is a temporary phenomenon. Without much time, drinkers will feel exceptionally cold. This is because of the heat loss in the body. Therefore, the more you drink, the colder you feel. This is not surprising.
At the same time, this so-called "drinking cold" is more likely to cause people to have a cold or frostbite. In particular, it is necessary to remind that relying on alcohol to protect the cold is even more detrimental to the elderly. Older people are not very sensitive to changes in body temperature, such as body temperature caused by drinking disorders caused by disorder, more likely to damage its thermoregulation.
In fact, drinking a small amount of wine in the winter is beneficial to the body, and it can have the effect of stimulating blood circulation, appetizing and boosting fluid. However, using alcohol to protect the cold is undesirable. In addition, drinking in the winter should be more careful. According to epidemiological investigations and studies, it is shown that the drinking-induced hemorrhagic disease in winter is more than ten times more than in summer. Such diseases as cerebral hemorrhage, stomach bleeding, and so on, and myocardial infarction also occur frequently in this season. Alcohol stimulants increase the risk and severity of these diseases.
What can you eat to protect the cold?
In fact, for keeping warm, it should mainly consider two factors, one is to eat nutritious, high-calorie foods to help the body increase calories; the other is to strengthen warming and exercise. The second aspect does not have much to say, but in the first aspect, you can choose to keep a lot of cold food.
For example, in the winter, eating and drinking more high-vitamin foods will help improve the body's ability to resist cold. Such foods as animal liver, carrots, pumpkins, etc. are rich in vitamin A, fresh rice flour, coarse grains, etc. Contains B vitamins, fresh vegetables, fruits and other rich in vitamin C. In addition, studies have also shown that eating more foods with high iron content during the winter can also help warm up the body. Such foods include animal liver, beef and mutton, spinach and egg yolk.
