人们冬天对包围身体的气象环境非常敏感,防寒保暖自然是冬季谈论最多的话题。气象保健学家研究证实,冬季人体保暖的三个重点部位是头、背、脚。先说说头部保暖。人的头部皮肤较其他部位的皮肤厚而致密,头部的血管及淋巴组织极为丰富,其中含有大量皮脂腺、汗腺、头发。头部常外露,毛孔也较大,最容易散失热量;尤其当人体活动时,头部易出汗,热量从此处大量蒸发散失。在散失的同时,因空气对流,风寒极易乘隙侵入人体。而在冬季,气温较低,即使处于静止状 People winter is very sensitive to the weather surrounding the body, cold warm nature is the most talked about topics in winter. Meteorologists study confirmed that winter, the body’s three hot spots are head, back and feet. Let me talk about the head warm. Human head and skin than other parts of the skin thick and dense, the head of the blood vessels and lymphoid tissues is extremely rich, which contains a large number of sebaceous glands, sweat glands, hair. Head often exposed, larger pores, the most likely to lose heat; especially when the human body activity, the head sweat easily, a lot of heat evaporated from here. In the loss at the same time, due to air convection, easy to take advantage of wind invasion into the body. In winter, the temperature is low, even at rest
