Which sign is most characteristic of mild hypothermia?

• A. Fever
• B. Confusion
• C. Hot, flushed skin
• D. Shivering

Answer: (D)

Shivering is the most characteristic sign of mild hypothermia because the body’s primary response to cold is to generate heat through involuntary muscle activity. This rapid, rhythmic muscle contraction helps raise the core temperature back toward normal. Fever represents the body fighting infection or overheating, not a cold response, so it’s not typical of hypothermia. Hot, flushed skin would suggest heating or fever rather than cooling, as hypothermic skin is usually cool and pale due to peripheral vasoconstriction. Confusion can occur as temperature falls, but the earliest and most reliable indicator in mild cases is shivering. Recognizing shivering guides you to start warming and monitoring promptly.
