中新网上海12月8日电 (陈静 喻文龙)冬季皮肤瘙痒是一个常见的问题，但很多人并不清楚其中的原 因以及如何有效预防。上海的皮肤科专家郑华娟8日对记者介绍，"冬季皮肤瘙痒的原因主要有三个方 面，一是环境因素，二是生理因素，三是生活习惯。" 据介绍，冬季，寒风凛冽，空气干燥，空气湿度大幅下降。皮肤表面的水分会随着干燥空气快速蒸 发，角质层作为皮肤的"保护壳"，一旦缺水就会变得粗糙、脆弱，原本紧密排列的角质细胞间隙变大， 外界的刺激物(如冷空气、粉尘)更容易侵入，引发瘙痒和敏感。同时，室内外温差大，从温暖的室内走 到寒冷的户外时，皮肤血管会快速收缩又扩张，反复刺激下，皮肤的耐受度会降低，尤其是脸颊、鼻尖 等暴露部位，容易出现泛红、灼热感。 皮肤表面的皮脂腺会分泌油脂，与汗液混合形成"皮脂膜"，这层膜能牢牢锁住皮肤水分，阻止水分 蒸发。专家指出，冬季气温低，皮脂腺的活性会随之下降，分泌的油脂量减少，皮脂膜的保护力变弱， 水分流失速度加快，干燥和瘙痒就会随之而来。此外，老年人的皮脂腺功能本身就会随着年龄增长而衰 退，冬季皮肤问题会更明显；而干性肌人群天生皮脂分泌少，也是冬季皮肤敏感的高发群体。 郑华娟直言，很多人在冬季 ...
