Heat-related illness is the spectrum of pathophysiologic response when the body becomes unable to regulate its core temperature.
Heat exposure and related illness have impacted military, athletic, and occupational populations throughout history with measurable morbidity and mortality. Only recently has the pathophysiology and optimum treatment been been more thoroughly researched.
Human beings, like other mammals, are endothermic animals that use both autonomic and behavioral mechanisms to maintain body temperatures within a narrow range (approximately 35°–41 °C or 95°–105.8 °F). Normal physiologic function is dependent on a relatively constant internal temperature as enzyme activity, immune responses, electrical conductivity, and membrane integrity have evolved to perform most efficiently within a narrow thermal spectrum. Dry heat gain occurs when surrounding ambient...
