Which signs are typical of hypothermia?

Hypothermia presents with signs that reflect the body's response to cold and cooling of the core. The most characteristic early sign is shivering, an automatic heat-producing muscle activity. As body temperature drops, mental status can deteriorate, leading to confusion. The skin may appear cyanotic or dusky because peripheral perfusion and oxygen delivery decline when the body concentrates blood flow to the core. The body also activates peripheral vasoconstriction to conserve heat, so the extremities feel cool and look pale or bluish. Other options don’t fit because jaundice and itching point to liver or biliary issues, hyperthermia and flushing indicate overheating or fever, and tachycardia with warmth suggests warming processes or fever rather than cooling.
