A human's blood is actually warmer than normal body temperature. Your body knows that it can live without arms and legs, and that the most medial parts of the body are the most vital ones. So to make sure that your core body doesn't get too cold and shut down, the blood is pulled toward the center of the body. This is why the arms, legs, and nose tend to get more cold than the rest of your body in cold weather.
