Which condition is defined as an internal body temperature less than 95°F?

Hypothermia is defined as a condition in which the internal body temperature drops below 95°F. This dangerous situation arises when the body loses heat faster than it can produce it, often as a result of prolonged exposure to cold environments. The physiological response includes shivering, confusion, slowed heart rate, and potentially serious complications if not addressed quickly. It is crucial to recognize hypothermia as a medical emergency that warrants immediate intervention to prevent further heat loss and restore the normal body temperature.

Other conditions mentioned, such as exposure, frostbite, and cold stroke, involve different symptoms and physiological responses related to cold environments but do not specifically refer to a body temperature below 95°F. Exposure may be a general term for being subjected to cold without any specific medical implications. Frostbite refers to the freezing of body tissues, particularly extremities, but again is not characterized by an overall body temperature drop. Cold stroke, while a term that may suggest a severe cold-related condition, is less commonly referenced compared to hypothermia and does not denote a specific low body temperature threshold.
