Quick Answer
To stay warm while waiting for rescue, it's essential to conserve body heat, find or create a shelter, and use natural resources such as fire and insulation. Use layers of clothing, a hat, and a warm sleeping bag to minimize heat loss. Stay active to maintain blood circulation.
Conserving Body Heat
Conserve body heat by staying active. Every 30 minutes, do a lap or stretch to maintain blood circulation and prevent numbness. Wear layers of clothing, including a hat, to minimize heat loss. A hat can account for 10% of body heat loss.
Creating Shelter
Create a shelter using natural resources. Look for a spot with a windbreak, such as a group of trees or a rocky outcropping. If no natural shelter is available, create a lean-to using branches and leaves. Use a space blanket or a tarp to create a waterproof roof. Make sure the shelter is well-ventilated to prevent carbon monoxide buildup from a fire.
Starting a Fire
Start a fire using dry, fluffy material such as dryer lint or small twigs. Use a fire starter or a lighter to ignite the material. Keep the fire small, about 2-3 inches in diameter, to conserve fuel. Place the fire in a pit or a ring of rocks to contain it and reflect heat back to the body. Use a fire grate or a tripod to suspend the fire above the ground and improve airflow.
