Can drinking in cold winter keep out the cold?

When the weather is cold, many middle-aged and elderly people, even some young people, have the habit of drinking to keep warm, thinking that drinking in winter can keep out the cold. Most people feel hot after drinking, especially in cold winter. People like to drink some wine to keep warm, but is this really the case?

It is incorrect for medical experts to say that drinking can keep out the cold. Drinking will only make it colder and even harmful to your health. As we all know, moderate drinking helps to promote blood circulation. The alcohol in wine enters the blood through the digestive tract, which promotes the expansion of capillaries in the skin, thus accelerating the blood circulation in the human body and radiating the heat in the body more quickly. This is why people feel warm.

At the same time, alcohol will anesthetize people's central nervous system and reduce their perception of the outside world, so they won't feel so cold. So it is wrong to keep out the cold by drinking alone. In winter, we should eat some nutritious food to increase calories. In fact, the ethanol component of alcohol will dilate blood vessels, accelerate blood circulation, and a lot of heat in the body will be emitted through the skin, leading to a drop in body temperature. Therefore, if you want to keep out the cold by drinking a little wine in the cold winter, be careful to catch a cold and get sick.

In addition, it is worth noting that wine contains alcohol. After drinking, the nerves will be excited for a short time and the whole body will feel warm and comfortable. But in fact, this is a precursor to the central disorder of regulating body temperature. Acute alcoholism caused by heavy drinking will lead to drunkenness. Therefore, we must pay attention to moderate drinking in winter and don't drink too much.

Health experts suggest that people's fear of cold in winter is actually related to the lack of inorganic salts in their diet. Therefore, we should eat more vegetables with roots in winter, such as carrots, lilies, sweet potatoes, lotus roots, green vegetables and Chinese cabbage, because the roots of vegetables contain more inorganic salts. Eating more foods rich in calcium, iron, sodium and potassium can improve the cold resistance, such as shrimp, shrimp skin, sesame paste, pig liver and bananas. The dishes of patients with hypertension should not be too salty, and should be low-salt diet, with a daily salt content of 2-3 grams.
