【背景介绍】

饮一杯酒之后虽然人会感到周身暖和,但这仅是一种错觉,人的体温实际上不升反降了。因为皮肤下的微细血管因饮酒而迅速扩张,血液由于表面扩大而较快地降温,体温也因而下降了。

【英文原文】

Cold Heart, Warm Hands, and Alcohol

Contrary to popular belief, alcohol does not make you warmer. It may give you the feeling that you’re getting warmer, but that’s just an illusion: really, alcohol makes you more susceptible to the cold.

In cold weather, the body reacts by routing blood away from the skin toward the internal organs. This prevents loss of heat through the skin and maintains the core temperature. But, alcohol reverses this effect by making you flush red.

This flush makes you feel warm for a few minutes, but you are really losing heat through the skin to the cold air. You could lose enough heat to begin hypothermia and not even realize it. As your skin feels warmer, the core body temperature is becoming colder and colder.
