It is important to work fast to get people out of the cold. Hypothermia victims need medical help as soon as possible. But it is equally important to move them slowly and gently.
Any rough or sudden movement can force cold blood from the arms, legs and hands deep into the warmer middle of the body. The sudden flow of cold blood can create shock, a serious condition. It can also cause a dangerously abnormal heartbeat.
The process of “rewarming” a person needs to be done slowly, in a hospital setting. Members of search-and-rescue teams have a saying, that victims are not dead until they are warm and dead.
An extremely low body temperature can cause the heart to beat so slowly that a pulse may be difficult to find. In other words, a person who is suffering from the effects of severe cold may seem dead, but still be alive.
