Many people also like to go hiking with large travel backpacks in the cold winter. But for most people, outdoor travel is not that simple, because it is also necessary to pay attention to how to keep warm in winter, especially when sleeping in a tent. So how should you pay attention to cold and warm when traveling in winter?
1. Fix the camp and level the sleeping surface
Clear snow, dead branches, stones, etc., and set up tents on a dry and flat location. This is the basic construction condition. Another tip is to fix your sleeping position into a shallow slot, which helps to reduce the potential heat loss from surrounding space and cold exposure.
2. Bring an insulated closed-cell foam sleeping pad
Cold air conduction is the source of heat loss when sleeping on the cold ground. In order to avoid heat loss, an insulating closed-cell foam sleeping pad can be placed under the moisture-proof pad. You can also use an ultra-light camping bed, and then put a moisture-proof pad on it, which can effectively insulate it.
Moisture-proof mats also have warmth retention, which can be measured by R value; R value refers to the ability of insulating materials to resist heat conduction. The higher the R value, the better the thermal insulation effect of the sleeping pad.
3. Use a small tent
Compared with large tents, small tents can keep warm better. At the same time, isolate the tent by reducing the surrounding space, such as placing carry on backpacks and extra gears around the inside of the tent to further isolate air communication. You can also use tape to glue a picnic mat or blanket to the inner wall of the tent to form a heat conduction shield.
4. Keep your body warm
Keep your body warm when you fall asleep at night outdoors. You can put a hot water bottle in your sleeping bag. You can also wear fleece clothes, a hat, and warm socks (avoid tight-fitting clothes). This can effectively keep the hands and feet warm to save energy.
Down is the most warm material, and down sleeping bags are also the first choice for winter camping. However, after the down is wet or wet with water, the warmth retention capacity will be greatly reduced, so pay attention to the dryness of the down sleeping bag. Before use, tap the down jacket to achieve the maximum volume or bulkiness.
It should be noted that do not bury your head in the sleeping bag when you fall asleep, because the moisture in the person's breathing will be wrapped in the sleeping bag.
6. Remove morning frost from the tent
Water vapor often condenses on the inner wall of the tent, and once it melts, it will wet the equipment in the tent. Therefore, when the sun is good at noon, first remove the morning frost on the outside of the tent, then open the tent, and turn the outside tent over and put it on the inside tent to let the sun or dry wind blow away the moisture.
Other equipment also needs to be stored in a waterproof bag or plastic bag. During the day, use an ice brush to sweep the ice crystals into collectible piles and then melt. If the weather is fine, dry the gear every day such as your travel laptop backpack.
