How to use outdoor sleeping bags in wild survival skills

2022-01-08

Sleeping in a sleeping bag is tricky. People who can't "sleep" will feel cold even if they use an alpine sleeping bag (minus 35 degrees) at a low temperature (minus 5 degrees), so how can they sleep warmer? When using a sleeping bag, there are many external factors that affect the performance of the sleeping bag. It should be noted that the sleeping bag itself does not generate heat, it only effectively reduces the loss of body temperature. The following conditions will help you sleep warmer.


  


Shelter from wind and moisture

In the wild, a sheltered tent can provide a warm sleeping environment. When choosing a camp, don't choose valley bottoms, where cold air gathers, and try to avoid ridges or valleys that are subject to strong winds. A good moisture-proof pad can effectively separate the sleeping bag from the cold and wet ground, and the inflatable effect is better. Two ordinary moisture-proof pads are needed on the snow.

Keep your sleeping bag dry

The water absorbed by the sleeping bag is not mainly from the outside world, but the human body. Even in extremely cold conditions, the human body will still expel at least a small cup of water during sleep. The thermal insulation cotton will bond and lose its elasticity after being wet, and the thermal insulation ability will decrease. If the sleeping bag is used continuously for several days, it is best to dry it in the sun. Frequent cleaning of the sleeping bag will keep the insulation elastic.


Put on more clothes

Some looser items can double as thicker pajamas. Filling the space between the person and the sleeping bag can also enhance the warmth retention of the sleeping bag.


Warm up before bed

The human body is the source of heat for the sleeping bag. If you do a short warm-up exercise or drink a hot drink before going to bed, your body temperature will increase slightly and help shorten the warming time of the sleeping bag.
