When you are in a survival situation, building a shelter should be a high priority.
A shelter can protect you against the elements (sun, wind, rain, snow, etc.) keeping you warm and dry, as well as protect
against natural enemies. The shelter should be large enough for you to lie down in, but it should be built only a bit bigger
than you are. This will help contain body heat while resting and sleeping. A shelter is a vital comfort to boost your moral,
and enhance your will to survive.
When looking for a shelter site, keep in mind the type of shelter (protection) you need. You would look for a spot that provides protection against wild animals and falling objects if at all possible, while still protecting you from the elements.
You also want a place free from insects, reptiles and poisonous plants. You may be able to find natural shelters as well
in such as caves or cliffs, or large trees with dry areas beneath them. Be sure of course there are no wild occupants already
using these shelters. Look for an area that will also allow for a small fire. It will keep you warm, and ward off any predators.
Heating Your Shelter
When body heat just isn't enough, there are other alternatives you can use to stay warm in your shelter.
