Which statement about treating heat exposure is incorrect?

• A. Immersing in cold water is recommended
• B. Move to a cooler environment and rest
• C. Hydration is important
• D. Apply fans to cool

Answer: (A)

Cooling the body is essential, but the method of cooling matters. Immersing someone in cold water isn’t advised for treating heat exposure in most situations because it can cause rapid and uncomfortable cooling, shivering that can actually raise metabolic heat, and potential cardiovascular or respiratory issues outside a controlled setting.

Safer first steps are to move the person to a cooler environment, have them rest, and ensure hydration with water or an electrolyte drink if they are conscious and not nauseated. Help cooling by using fans to promote evaporation and applying cool, damp cloths or tepid water to the skin. Remove excess clothing to aid heat loss.

Watch for warning signs that require urgent care, such as confusion, fainting, seizures, vomiting, or a very high body temperature, and seek medical help if these occur.
