When the body is exposed to cold, the first defensive move is to generate heat through involuntary muscle activity—shivering. This reflex is the earliest sign because it directly reflects the body's attempt to raise core temperature before other bodily functions are noticeably affected. As cooling continues, cognitive and coordination changes become evident, such as confusion or slurred speech, and nausea can occur, but these appear later. If shivering stops, that can indicate worsening hypothermia and the need for urgent warming and medical care.
