The normal physiologic thermoregulatory responses start to fail once the core body temperature reaches this level, leading to the body's inability to generate enough heat to maintain bodily functions. Hypothermia can be subdivided into primary and secondary hypothermia.1 Primary accidental hypothermia occurs when a previously normal individual is subjected to an environmental stress. Secondary accidental hypothermia occurs when a predisposing factor leads to disruption of temperature homeostasis and increases the individual's susceptibility to lesser environmental stresses (e.g., drug intoxication, trauma, and endocrine disorders). Drug intoxication and trauma are acquired conditions that are highly associated with the development of hypothermia.1
