Which of the following is NOT a category of heat injury?

Heat injuries are categorized mainly into three types: heat cramps, heat exhaustion, and heat stroke. Each of these conditions has distinct signs and symptoms, usually tied to the body's response to prolonged heat exposure and physical activity.

Heat cramps involve painful muscle spasms due to the loss of electrolytes and hydration, which typically occurs after intense exercise in hot conditions. Heat exhaustion is more severe and presents with symptoms like heavy sweating, weakness, dizziness, and possible nausea when the body overheats and starts to lose its ability to cool itself. Heat stroke is the most serious heat-related condition, characterized by a body temperature above 103°F, confusion, altered mental state, and potential loss of consciousness, marking a critical point where body cooling mechanisms have failed.

The term "heat paralysis" does not correspond to an established category of heat injury within the recognized definitions and conditions. While there may be neurological effects from heat exposure, "heat paralysis" is not a medical designation or a commonly accepted term in relation to heat-related illnesses. Therefore, identifying this term as not fitting within the recognized categories of heat injury is accurate.
