Y1 - 2019 N1 - T2 - Goldfrank's Toxicologic Emergencies, 11e AB - Despite exposure to wide fluctuations of environmental temperatures, human body temperature is maintained within a narrow range.16,120 Elevation or depression of body temperature occurs when (1) thermoregulatory mechanisms are overwhelmed by exposure to extremes of environmental heat or cold; (2) endogenous heat production is either inadequate, resulting in hypothermia, or exceeds the physiologic capacity for dissipation, resulting in hyperthermia; or (3) disease processes or xenobiotic effects interfere with normal thermoregulatory responses to heat or cold exposure.
