Tips for using sleeping bags
Sleeping bags are tricky. People who do not "sleep" will feel cold at low temperatures (-5 °) even when using an alpine (-35 °) sleeping bag.
So how can I sleep more warmly? 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 is only effective in reducing body temperature loss. The following conditions will help you sleep warmer.
In the wild, a windproof tent provides a warm sleeping environment. When choosing a camp, don't choose the bottom of the valley, where the 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. The inflatable effect is better. Two ordinary moisture-proof pads are required on the snow.
Keeping your sleeping bag dry is important to improving the quality of sleep in your sleeping bag. The water absorbed by the sleeping bag is not mainly from the outside, but the human body. Even in extremely cold conditions, the human body will still discharge at least a small cup of water during sleep. The insulation cotton will stick and lose its elasticity after being dampened, and the insulation ability will decrease. If the sleeping bag is used continuously for many days, it can be dried in the sun. Wash the sleeping bag frequently to keep the insulation cotton elastic.
Of course, wearing more clothes during sleep can also achieve satisfactory results. These clothes need to be better than fluffy clothes, they can double as thick pajamas. Filling the space between a person and a sleeping bag can also enhance the warmth of the sleeping bag.
The human body is the source of heat in the sleeping bag. For example, if you do a short warm-up exercise or drink a hot drink before going to bed, it will slightly increase the body temperature and help shorten the warming time of the sleeping bag.
