Which is a late sign of hypothermia?

• A. Shivering
• B. Confusion
• C. Loss of consciousness
• D. Cessation of shivering

Answer: (D)

Shivering is how the body tries to generate heat in the early stages of cold exposure. As the core temperature drops further, the body’s metabolism slows and shivering can eventually stop. When shivering ceases, it means the thermoregulation system has failed and the person is entering a very advanced, potentially life-threatening stage of hypothermia. This cessation signals a late stage because active heat production has effectively shut down, often alongside worsening mental status such as confusion or decreasing responsiveness, and can progress toward unconsciousness. So, stopping shivering is the hallmark late sign. If someone isn’t shivering but is obviously hypothermic, treat it as a medical emergency and begin careful warming and supportive care.
