Question: Question: Is resistive heating more effective than metallic-foil insulation in an experimental model of accidental hypothermia : A randomized controlled trial?
Answer: Resistive heating more than doubles the rewarming rate compared with that produced by reflective metal foil and does so without producing an afterdrop. It is therefore likely to be useful in the prehospital setting.

Answer:
yes
