Which of the following is NOT one of the types of heat exposure illnesses?

Frostbite is considered a cold-related injury rather than a heat exposure illness. It occurs when skin and underlying tissues freeze due to prolonged exposure to cold temperatures. In contrast, heat cramps, heat exhaustion, and heat stroke are all conditions resulting from overexposure to heat and can occur during hot weather or physical exertion in warm environments.

Heat cramps typically involve painful muscle contractions due to loss of electrolytes and fluids, often occurring after intense exercise or labor in hot conditions. Heat exhaustion is characterized by symptoms such as heavy sweating, weakness, dizziness, and nausea, and can lead to heat stroke if not properly addressed. Heat stroke is a more severe condition that occurs when the body overheats, leading to a failure of the body's thermoregulation and potentially resulting in severe health consequences if not treated promptly. Understanding these distinctions is crucial for recognizing and responding to heat-related illnesses properly.
