What's the main key to building an effective emergency shelter?
Answer Make it only large enough for you to barely squeeze inside
Smaller shelters take less time and calories to build and are more effective due to less dead air space. With a well insulated shelter our body heat will stay inside warming up the dead air space around us, just like our clothes do, as well as keeping out the elements.
