I heard being frozen is like being lit on fire, very painful. Can anyone confirm this?
Actually, no. I do swift water and frozen rescues with local FDs and F&G. In both cases people resesitated(sp?) commonly share the same experiences: A light being closed in on all sides by darkness and a sense of calm, peace. In fact most people say it's like falling asleep and "being embraced".
We are instructed that one of the real danger signs is from someone refusing blankets or dry clothes. In the extreme cases of hypothermia people actually feel warm and comfortable. The cold and shivering are the 2nd and 3rd phase, which pass as the body begins to shut down functions not required to keep it's core temp up for survival.
The "Pain" comes from shock. This can easily be done 2 ways: Either by cooling down too quickly (which quickly passes; put your hand in a bucket of ice if you don't believe me and be amazed that in less than 2 minutes you will have no feeling and very slugish movements!) or from rescue personnel heating a victom up too fast. One of the worse things we can do is to apply heat a cold victom.
The burning sensation, that I am familiar with, often comes from Frost-bite, which takes a loong time to develop as the muscles die off, or again heating a victom too quickly.
Just my experience.
I end suffering when it's the only recourse by setting a bowl of water in the freezer. I wait the extra time needed to ensure that the water surface has iced over well enough that I need to use a spoon to break the surface (the water underneath is liquid) and I place the poor fellow in this. It's near instant as can be I guess....
