As an EMT I learned to remove the person (myself) from the cold, remove wet clothes (get in your sleeping bag) and apply heat (like a hot water bottle or hot hands packet) to the neck, groin or armpits because those are your largest arteries and that heats your blood, therefore your body, the fastest. Drinking/eating the heat is much less effective than applying it externally at the places I just listed.
