Quite often, the scene findings in cases of fatal hypothermia show evidence suggesting a struggle. The premises may be in disarray, and affected individuals may be found under newspapers or furniture. Presumably, once hypothermia has set in, they become confused and disoriented, and attempt to seek warmth in unusual places. They also suffer from "paradoxical undressing", or "hide-and-die" behaviour, thought to be due to a disturbance of the temperature-regulating function of the hypothalamus that causes a feeling of overheating (and resultant attempts to cool down such as undressing) as the body's core temperature drops.
