Hypothermia is the main cause of death from cold weather, claiming over 700 lives per year. When the body loses heat faster than it can produce it, hypothermia occurs. Frostbite is also a major risk in cold conditions as it affects the respiratory and integumentary systems, making breathing difficult and damaging skin. To prevent hypothermia, it is important to dress in layers, carry extra clothing, wear protective headgear and boots, stay dry, and consume high-energy snacks. The signs of hypothermia should also be recognized.
