In a cold environment, which action helps reduce heat loss by preventing continued exposure to cold air?

• A. Rewarm without monitoring
• B. Carry out physical activity in the cold
• C. Move the patient to a warmer environment
• D. Remove all clothing

Answer: (C)

In a cold environment, heat loss is driven largely by convective heat transfer from the body to moving cold air. Moving the person to a warmer environment interrupts that exposure, so the rate of heat loss drops quickly and core temperature is protected. Once sheltered, you can add insulation like blankets to further limit heat loss. Other actions either fail to stop the cold air from reaching the skin (removing clothing increases heat loss) or add activity or unnecessary risks without addressing the ongoing exposure.
