Secondly, in the cold winter, many people tend to wear a lot to keep warm, thinking that the more they wear, the warmer they will be. In fact, this idea is very one-sided. Because clothes themselves do not generate heat, they only play the role of isolation, buffering the convection between the cold air outside and the hot air on the body surface, so that the heat of the human body can be preserved, thus making the human body feel warm. Clothes are put on one after another, and the thickness of the air layer increases accordingly to keep warm. From a physiological point of view, wearing too thick clothes will inhibit the adaptability of body temperature regulation and weaken the ability to keep out the cold.
Finally, winter clothes should have a certain quantity and appropriate thickness, and winter clothes should choose light and warm down products and leather clothes that are not suitable for cold air infiltration.
