Sleeping sleeping bags are tricky. People who do not "sleep" use cold (-35 °) sleeping bags and feel cold at normal low temperatures (-5 °).
So how can I sleep more warmly? There are many external factors that affect the performance of sleeping bags when using sleeping bags. It should be noted that the sleeping bag itself is not hot, it is only effective in reducing body temperature loss. The following conditions will help you sleep more warmly.
In the wild, a windproof tent provides a warm sleeping environment. When choosing a camp, don't choose the bottom of the valley, where there is a gathering place of cold air, and try to avoid the ridges or hills that are subject to strong winds.
A good moisture-proof pad can effectively separate the sleeping bag from the cold and damp ground. The inflatable effect is better. Two common moisture-proof pads are needed on the snow.
Keeping your sleeping bag dry is important to improve the quality of your sleep in your sleeping bag. The water absorbed by the sleeping bag is mainly from the outside world, but the human body. Even in extremely cold conditions, the human body will still discharge at least a small cup of water while sleeping. Insulation cotton will bond and lose its elasticity after damp, and the insulation capacity will decrease. If the sleeping bag is used continuously for many days, it can be dried in the sun. Frequent cleaning of the sleeping bag can be used to keep the insulation cotton elastic.
Of course, wearing more clothes during sleep can also achieve satisfactory results. These clothes need to be softer and they can be used as thicker pajamas. Filling the gap between the person and the sleeping bag can also enhance the warmth of the sleeping bag.
The human body is the source of heat for sleeping bags. For example, doing a short warm-up exercise or drinking a hot drink before going to sleep will slightly increase the body temperature and help shorten the warming time of the sleeping bag.
