The extremities of a body would colder the fastest. This is because, if someone cools down lower than their normal body temperature, then the capillaries on the surface of the skin contract, letting less blood through, which would reduce heat loss. This is called vaso-constriction, and it happens because the blood stays more towards the major organs of the body, keeping them at the right temperature, so they can work efficiently.
