Which of the following is a sign of hypothermia?

1. Rapid heartbeat

2. Heavy sweating

3. Uncontrollable shivering

4. Hot, dry skin

The correct answer is: Uncontrollable shivering

Uncontrollable shivering is a sign of hypothermia because when the body's temperature drops, it responds by trying to generate more heat through shivering. This involuntary muscle movement is an attempt to increase the body's temperature and prevent further heat loss. In contrast, options A, B, and D are not characteristic signs of hypothermia. Rapid heartbeat and heavy sweating are more associated with heat-related conditions, while hot, dry skin is not typically seen in individuals experiencing hypothermia.
