Quick Answer
To prevent hypothermia at high elevation, wear layers of breathable clothing, stay dry, and maintain a body temperature above 95°F (35°C). This can be achieved by staying active, consuming caloric-rich foods, and using portable heaters or shelters. Adequate hydration and proper gear are also essential.
Staying Dry and Warm
At high elevation, the air is dry and the wind can be fierce. To prevent moisture buildup and subsequent hypothermia, wear clothing that allows for airflow and moisture-wicking properties. This includes base layers made of merino wool or synthetic fabrics, mid-layers of fleece or down, and outer layers of waterproof and breathable materials like Gore-Tex or similar technology. Keep your head, hands, and feet dry by using hats, gloves, and gaiters.
Managing Body Temperature
To maintain a body temperature above 95°F (35°C), stay active through regular exercise, such as walking, climbing, or skiing. This helps to generate body heat and maintain circulation. In addition, consume caloric-rich foods like nuts, dried fruits, or energy bars to keep your body fueled. If you’re planning to stay in one place for an extended period, use a portable heater or a shelter to minimize exposure to wind and cold.
Hydration and Gear
Proper hydration is crucial at high elevation, where the air is thin and the body loses moisture quickly. Drink at least 2-3 liters of water per person per day, and consider using a hydration bladder or a water filter to ensure access to clean drinking water. In addition, bring a first-aid kit, a map, a compass, and a GPS device to navigate the terrain and respond to emergencies. A portable shelter, a sleeping bag, and a warm hat can also help to prevent hypothermia in case of an unexpected night spent outdoors.
