Wilderness survival in the bitter cold is not for the faint of heart. Record low temperatures following this snowstorm could create the need for emergency shelters, especially if you find yourself outdoors and fear exposure. Your Top Priorities In a Cold Environment

Your primary concerns in such an unforgiving environment is shelter and water. You want to ensure that you can maintain your body heat. One small mistake like accidently losing  glove or eye protection can cause detrimental issues like hypothermia, frostbite and even snow blindness. In addition, the clothing layers you wear outdoors could make all the difference in the world. Proper layers insulate and prevent heat loss. In an emergency situation, you can use dry leaves as an emergency layer of insulation if you are concerned with hypothermia.

A trick that many outdoor enthusiasts use to making a shelter in cold temperatures, is having a thermal barrier to trap heat in the shelter. This one item can make all the difference in the world! An example of this type of barrier is Mylar blankets. This lightweight prepper item is one of the most multipurpose items you can take with you and a must-have for your outdoor gear! Ever wonder about all the ways you can use Mylar?

Water is another top priority. Dehydration is a major risk when outdoors. Cold weather studies at the University of New Hampshire show increased risk for dehydration, a condition many associate with hot weather emergencies. “People just don’t feel as thirsty when the weather is cold,” says Robert Kenefick, UNH associate professor of kinesiology. “When they don’t feel thirsty, they don’t drink as much, and this can cause dehydration.” Moreover, excessive perspiration, heavy clothing and increased respiratory fluid loss are other factors that contribute to dehydration in cold climates. For example, when you can see your own breath, that’s actually water vapor that your body is losing. The colder the temperature and the more intense the exercise, the more vapor you lose when you breathe.

As well, you want to put careful thought into the tools you carry with you. Not only should the tools be helpful, but some should serve a double purpose of preventing hypothermia. Some other tools to consider are:

Protect yourself from the elements by using branches, sticks, tarps or whatever you have available. Pine branches are great for wind-proofing your shelter and preventing heat loss from the ground. Body heat can quickly escape if you do not have a ground insulator. If you can make your bedding area off the ground, you will be able to conserve more body heat. Consider pine needles, leaves, spruce boughs and/or branches, or even building up the snow around your primitive shelter. Take into consideration your energy output on building…
