You shiver to do what?

You shiver to do what?

• A. Maintain body heat
• B. Cool the body
• C. Increase sweat
• D. Lower temperature

Answer: (A)

Shivering is the body's way to generate heat when you’re cold. When temperature sensors detect a drop, the nervous system triggers rapid, involuntary contractions of skeletal muscles. These contractions burn energy and release heat, boosting metabolic heat production to help keep the core temperature from falling. This is a heat-producing response aimed at maintaining body heat in cold conditions. The other options describe cooling processes (increasing sweat) or actions that would lower body temperature, which are not the purpose of shivering.
