The principle of dressing and keeping warm

The principle of dressing and keeping warm is achieved by reducing heat conduction, that is, clothing retains heat through convection between the heat of the cold air body surface. Therefore, if you want to dress and keep warm, you must reduce heat conduction! From this point of view, usually when we wear multiple layers of clothing, we should pay attention to retaining the air between the interlayers, so as to reduce heat conduction. This can also explain the saying that wearing many pieces of clothing does not necessarily keep warm, the less air in the interlayer of clothing, the faster the heat conduction. If you want to dress warmly in winter, you must first remember these three points: thin and soft inside, warm in the middle, and windproof outside. As long as you wear these three layers of clothing, and protect your head, neck, hands and feet, knees and other parts that are particularly afraid of cold, remember to wear a hat and tie a scarf when you go out, you can protect yourself from cold weather.
