Arctic highs
You probably know that you shouldn't drink anything alcoholic on a really cold day because it makes you feel warmer, but it delays shivering, which is a normal method of generating body heat.

Alcohol also gives a false sense of confidence, which can lead to doing foolish things. And it's a diuretic, so it reduces blood volume.

But there is a time and place when alcohol could make the difference, according Arctic Medical Research.

While alcohol is dangerous at moderately low temperatures, it still has benefits under arctic conditions. According to researchers at Karolinska Hospital in Stockholm, alcohol protects against the rapid heartbeat that usually appears after exposure to very low temperatures. It also protects against tissue freezing, but only at polar temperatures.
