Question

Heat stroke is primarily caused by

• A. Excessive heat production
• B. The inability to sweat
• C. Conductive heat gain
• D. Inability to lose heat by radiation

Answer 1

Answer: (D)

Inability to lose heat by radiation

Heat stroke is caused by the overheating of the body due to prolonged exposure to high temperature. Heat is exchanged with the environment in four ways such as conduction, convection, radiation, and evaporation. Conduction refers to heat loss through direct contact with a cooler object. Convection is the dissipation of heat when relatively cool air passes over exposed skin. Radiation is the release of heat from the body directly into the environment. Evaporation through perspiration is the body’s most effective method of cooling under most circumstances.

Therefore, the correct answer is option D.
