Maintaining body temperature in trauma care is essential because exposure and shock put patients at high risk for hypothermia, which directly worsens bleeding and survival. When the body cools, the coagulation system doesn’t work as well—enzymes run more slowly and platelets don’t function optimally—so bleeding can continue and clotting becomes unreliable. This coagulopathy associated with hypothermia is linked to higher mortality in trauma patients. That’s why keeping the patient warm matters most: by preserving heat through blankets and a warm environment (and using warmed fluids when available), you help maintain proper coagulation and improve outcomes. While warmth can also aid comfort and may influence other risks, the key impact in the field is reducing hypothermia-related coagulopathy and death.
