The principle of dressing and keeping warm
The principle of dressing to keep warm is realized by reducing heat conduction, that is, clothes save heat through convection between cold air and surface heat. So if you want to wear clothes to keep warm, you must reduce heat conduction! From this point of view, when we wear multi-layer clothes, we should pay attention to keeping the air between the layers to reduce heat conduction. This can also explain the saying that wearing too many clothes is not necessarily warm. There is less air in the interlayer of clothes, but the heat conduction will be accelerated. If you want to keep warm in winter, you should first remember these three points: it is thin and soft inside, warm in the middle and windproof outside. As long as you wear these three layers of clothes, protect your head, neck, hands, feet, knees and other parts that are particularly afraid of cold, and remember to wear a hat and scarf when you go out, you can resist the cold weather.
