In maritime navigation class, we were taught that artificially heating a person who has been chilled down (that is, heating by giving them something warm to drink, putting them in a hot shower etc.) sometimes result in something very similar to a cold shock response, a sort of "hot shock response" known to cause severe after-effects and apparently even death. Tests carried out by the Swedish Sea Rescue Society along with data from over one hundred years of recorded incidents, showed that the safest way to sustain a person suffering a cold shock or near hypothermia is to simply uncloth them (if soaked in water), blanket them lightly, and let their body heat itself up to normal temperature, utilizing the time in parallel to make sure heart rate and blood pressure stabilizes in calm tempo.
