Which sign indicates progression to severe hypothermia?

• A. Shivering increases
• B. Warm skin
• C. Rapid movement
• D. Shivering stops

Answer: (D)

Stopping shivering signals progression to severe hypothermia. Shivering is the body's main heat-generating response; when someone is cold, it helps raise core temperature. As hypothermia worsens and core temperature falls, the body's systems slow down, and shivering can fade or stop. The absence of shivering in a person who is cold means their heat-generating mechanism is failing, indicating a dangerous stage often with reduced consciousness and a higher risk of cardiac arrest. In contrast, shivering increasing would indicate earlier stages, warm skin is not consistent with hypothermia, and rapid movement is not typical of severe hypothermia, which tends to slow or stop movement.
