I think I said the same thing only different, lessee:

You want to keep the core temp up, but keep the extremities well insulated. Keeping the overall body temp up requires that the core temp be maintained. If the person is warm but in shock, then preserving the temp by insulating the extremities will keep the temp from falling off, as well as providing more comfort to the individual.

Now if there's a problem with having enough insulation or too much exposure to the elements, then it is going to take all of your effort just to keep core temps up. There, that should qualify it a little better. Core temps first, extremities if possible. That fits what I said before.

Thanks Pete for helping me clear that up.
