Quick Answer
To avoid hypothermia while using a tarp shelter, maintain a dry environment, use proper insulation, and stay active. Monitor your body temperature and adjust your shelter accordingly. Use a space blanket or emergency bivvy sack as a last resort.
Choosing the Right Shelter Location
When setting up a tarp shelter, it’s essential to choose a location that protects you from wind and precipitation. Look for a spot that’s partially shaded and has minimal exposure to direct sunlight. Avoid areas with standing water or near bodies of water, as these can be breeding grounds for mosquitoes and other insects. Consider a location with a natural windbreak, such as a group of trees or a rocky outcropping.
Insulation and Ventilation
To maintain a comfortable body temperature, ensure your tarp shelter has proper insulation and ventilation. Use a tarp with a waterproof coating and a thickness of at least 1.5 mils. Create a lean-to structure by attaching the tarp to a tree branch or a makeshift pole, leaving enough space for airflow. Add insulation such as leaves, grass, or a space blanket to the floor and walls of your shelter. Aim for a temperature range of 50-60°F (10-15°C) by adjusting the angle of your tarp and the amount of insulation used.
Staying Active and Prepared
To prevent hypothermia, stay active and engaged in your surroundings. Engage in physical activity such as jumping jacks or stretching exercises to maintain blood circulation. Monitor your body temperature regularly by feeling the back of your neck or wrist. If you notice any signs of hypothermia, such as shivering, confusion, or drowsiness, take immediate action to warm up. This may involve adding more insulation, removing wet clothing, or using a space blanket to retain body heat.
