Can you drink cold to drink?
It is a misunderstanding for the public to drink and warm the cold. People feel hot after drinking, because sympathetic nerves are excited and the body's metabolism is accelerated, releasing energy. However, this is a short-term comfort. With the expansion of blood vessels, the loss of cold after losing a lot of heat will feel cold.
In the cold days, people often drink a few glasses of wine to warm their bodies, thinking that drinking can keep warm. In general, drinking can increase the speed of breathing, the blood vessels to dilate, the speed of blood circulation, the increase of calorie consumption, and make people feel warm. At the same time, alcohol contains alcohol, which causes short-term excitement of nerves after drinking. Mouth and throat mucous membranes also showed slight trembling. In this way, the whole body has a warm and comfortable feeling. In fact, this is a precursor to the disturbance of the central nervous system.
Especially when drinking for a long time, it can cause dysfunction of body temperature regulation and increase of heat loss. At this time, the stomach is anesthetized by alcohol and its function is also obviously reduced. The body's heat production function is weakened. One of the cold is to eat nutritious food, increase calories; the second is to strengthen warm. If you simply rely on drinking to keep warm, you are not cold-resistant. Therefore, we should not drink cold.
Drinking alcohol can increase the speed of breathing, blood vessels, and blood circulation, making people feel warm. At the same time, alcohol contains alcohol. After drinking, it leads to short-term excitement of the nerve. The body is warm and comfortable. feel. However, in fact, this is a precursor to the disturbance of the central nervous system, and acute alcoholism caused by heavy drinking can cause drunken people to become unconscious. Intoxicated people are intoxicated, and if they are drunk in the cold outside, there will be danger of freezing.
After drinking alcohol, the alcohol in the wine enters the bloodstream, enters the central nervous system, and functions as an anesthetic, which reduces the sensitivity of the body to external environmental stimuli, and is therefore insensitive to cold reactions, and causes the drinker to mistakenly believe that drinking alcohol protects the cold. Ethanol causes blood vessels to dilate, blood circulation accelerates, and a large amount of heat in the human body dissipates through the skin, which in turn causes the body temperature to drop. Therefore, to drink cold, not only does not achieve cold function, but it is easy to make people have colds, frostbite and other symptoms.
