So how can I 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 body temperature loss. The following conditions will help you sleep warmer.
In the wild, a windshield tent can provide 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 the 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 required on the snow.
Keeping the sleeping bag dry is important to improve the quality of sleep in the sleeping bag. The water absorbed by the sleeping bag is not mainly from the outside world, but from the human body. Even in extremely cold conditions, the human body will discharge at least a small cup of water during sleep. After being damp, the thermal insulation cotton will stick and lose its elasticity, and the thermal insulation ability will decrease. If the sleeping bag is used continuously for many days, it can be dried in the sun. Frequent cleaning of sleeping bags can be used to keep the thermal insulation cotton elastic.
Of course, wearing more clothes during sleep can also achieve satisfactory results. These clothes need softer clothes, and they can also be used as thicker pajamas. Filling the gap between the person and the sleeping bag can also enhance the warmth retention of the sleeping bag.
