Hypothermia is a dangerously quick loss of body heat, most common in cold and damp weather at high altitudes or high latitudes—be particularly careful in areas with major temperature changes between day and night, or sun and shade. Symptoms include shivering, disorientation, loss of motor functions, skin numbness, and physical exhaustion. The best remedy is warmth, shelter, and food; unlike cottons, woolen clothing retains warmth even when wet. Avoid falling asleep; in truly hazardous conditions, it’s possible you will not regain consciousness. Carry drinking water and high-energy snacks.
