The warming effect of alcohol is a dumb deception of heat receptors. The body, believing it is hot, begins to actively cool even more.
WOW: Do not mislead people, please, in the cold, the vessels that close to the surface of the body begin to narrow, all the heat goes to the internal organs, important for life. Alcohol also has a vasodilating effect, yes, you will be more comfortable when you drink and the limbs and face will become the body, but the internal body temperature will sink sharply.
Zzz: Hey, hot Finnish guys, stop fighting! You say the same thing with different words. I can tell others: whoever drinks vodka in a swallow will die happier in a dream.
