每到春天,人们脸上的皮肤大多变得干燥、粗糙,甚至会脱皮、长小疙瘩,或呈苔癣状等,影响美容。科学研究表明,这种春季皮炎与中波紫外线照射密切相关。 据科学家测定:在一年四季中,春季阳光紫外线含量最高,冬季紫外线含量最低。科学家还就人们对紫外线敏感性作了各方面的统计,按季节分:春季敏感性最高;冬季则最低;按人的工作环境来分:室内工作者对紫外线的敏感性高,室外工作者较低;按年龄组分:青春期人对紫外线敏感最高,幼儿与老年人敏感性低;按性别来分,女性对紫外
Every spring, most people’s skin becomes dry, rough, and even peeling, lumps, or lichen-like, affecting the beauty. Scientific research shows that this spring dermatitis is closely related to UVB irradiation. According to scientists to determine: throughout the year, the highest UV sunshine in spring, the lowest in winter UV. Scientists also make people’s sensitivity to ultraviolet light in all aspects of statistics, according to the season: the highest sensitivity in spring; winter is the lowest; according to the work environment of the people: indoor workers sensitivity to ultraviolet light, outdoor workers than Low; by age component: the highest sensitivity to ultraviolet light in adolescents, children and the elderly is low sensitivity; by gender, the female UV
