In emergency resuscitation, clinicians watch for the "lethal triad": hypothermia, metabolic acidosis, and coagulopathy. These three conditions fuel one another in an accelerating spiral. Trauma-induced hypothermia differs sharply from mild accidental chilling because it strips away the body's natural defensive compensation mechanisms.

Under ordinary cold exposure, a conscious person shivers violently, generating internal heat through involuntary muscle contractions, while peripheral vasoconstriction shunts warm blood toward the heart and brain. In severe trauma, those defenses fail immediately:

First, acute neurogenic shock from spinal cord disruption severs autonomic communication. Blood vessels in the extremities fail to constrict; instead, they dilate completely, dumping core warmth directly into the surrounding frozen ground. Second, hemorrhagic shock drops circulating blood volume, starving skeletal muscle of the oxygen needed to sustain shivering. Third, cellular energy production stalls. Once core temperature slips below 30°C (86°F), the brain's hypothalamus ceases all attempts to regulate thermal balance, allowing the core to cool at the ambient rate of an inanimate object.
