In hypothermia, the body temperature is dangerously low (below 95 F or 35 C), and the body has lost capacity to regulate its temperature. The symptoms typically begin gradually, and eventually, thought process and brain function are affected. Symptoms include shivering, slow breathing, weak and slow pulse, and drowsiness. Mood changes, irritability, poor coordination, confusion, poor judgment, slurred speech, and gait disturbances are common. Sometimes affected people remove their clothing in spite of a cold environment (paradoxical undressing). There is a progressive decrease in consciousness, and coma may ensue.
