You reach a point where your body core thinks it’s too hot, some victims of hypothermia are found naked, having stripped their clothes off because they literally thought they were overheating. It’s called paradoxical undressing.
Twenty to fifty percent of hypothermia deaths are associated with paradoxical undressing. This typically occurs during moderate to severe hypothermia, as the person becomes disoriented, confused, and combative. They may begin discarding their clothing, which, in turn, increases the rate of heat loss. One explanation for the effect is a cold-induced malfunction of the hypothalamus, the part of the brain that regulates body temperature. Another explanation is that the muscles contracting peripheral blood vessels become exhausted (known as a loss of vasomotor tone) and relax, leading to a sudden surge of blood (and heat) to the extremities, fooling the person into feeling overheated.
Some interesting passage about lacking the food in the front during Winter War. An incident happened (known as “sausage war”) where attacking Russians behind Finnish lines came upon a Finnish field kitchen. The starving Russians ended up halting to eat anything they could find.
