What is hypothermia?

I think its something to do with being dead cold?

My grandad was talking about someone he used to know who died from it a couple of days ago, so I'm just curious to know what it is.

And yes, I might sound like an idiot or whatever, but I dunno...

ya its from the cold, your body shuts down.

Hypothermia is a condition in which an organism's temperature drops below that required for normal metabolism and bodily functions. In warm-blooded animals, core body temperature is maintained near a constant level through biologic homeostasis. But when the body is exposed to cold its internal mechanisms may be unable to replenish the heat that is being lost to the organism's surroundings.

Hypothermia is the opposite of hyperthermia, the condition which causes heat exhaustion and heat stroke.

yeah...this happened to my boyfriend. we were out drving, hit a snowbank and got stuck in a blizzard. we were stuck in his truck till the morning when we could see outside. he walked (to a destination 40 min away) through the snow and blizzard to get help for us. he got hypothermia, but didn't care. he wouldn't let the emt's put him in an ambulance until he saw that they had found me.
