It is often seen in many film and television works and literary works that when people are trembling in the cold winter and snow, someone always hands them a "burning knife" and "stuffy donkey", hoping to warm their bodies. Can drinking alcohol in the winter really warm up?
First of all, let's figure out why many people feel "warm" after drinking.
Many people know that the more "warm" the wine, the higher its alcohol content. After drinking alcohol, alcohol stimulates the thickening of capillaries on the surface of the body and speeds up blood circulation. Humans are thermostatic animals, in order to maintain a body temperature of about 37 ° C, blood circulation constantly transmits the heat generated by the liver and muscles in the body to all parts of the body.
So we can also deduce what this is all about: under the stimulation of alcohol, the blood flows to the surface of the body with heat at an accelerated rate (which is why it is easy to blush after drinking), and there are a large number of temperature receptors distributed here, which quickly make us feel "hot". --So, drinking alcohol can't be considered a warm body, at best it is a warm face.
Maybe some friends will ask: wine is made of grain and fruit, and it "warms up" by providing heat, can't it?
In fact, in the process of brewing, yeast has consumed a part of the energy, its own calories have been reduced, the provision of calories is also limited; more importantly, not everyone has a corresponding enzyme, can convert the metabolite of alcohol acetic acid into acetyl-CoA (it can further decompose a large amount of thermogenesis). Therefore, many people who are born with "bad alcohol" have no way to obtain a large number of calories from wine.
Therefore, wine really can't warm up! And while the blood vessels are dilated, the skin will also take away a lot of heat, accelerating heat dissipation - which may lead to colder!
