Hands, arms, feet, and legs may become cool to touch. You may notice the underside of the body becoming much darker in color. The skin may turn a bluish color with purplish splotches. Both occur because the blood circulation is slowing down.
Use blankets for warmth and to prevent the feeling of being cold. Do not use an electric blanket or heating pad. Be aware that occasionally the arms and legs may be cool to touch but the person states that he or she is hot and kicks off the blankets.
