Which of the following is NOT a heat-related injury?

Frostbite is classified as a cold-related injury rather than a heat-related one. It occurs when skin and other tissues freeze due to prolonged exposure to cold temperatures. The condition primarily affects exposed areas such as fingers, toes, nose, and ears.

In contrast, heat cramps, heat exhaustion, and heat stroke are all conditions related to excessive heat exposure. Heat cramps involve painful muscle spasms due to loss of electrolytes through sweating. Heat exhaustion is characterized by heavy sweating, weakness, and potential fainting as the body struggles to regulate temperature. Heat stroke is a severe medical emergency that results from prolonged exposure to high temperatures, leading to a failure of the body's temperature-regulating mechanisms. Understanding these distinctions is essential for recognizing and treating various environmental injuries appropriately.
