现代科学证实,太阳辐射的多种光线中包括可见光、红外线、紫外线和射线。太阳照在人身体上时,可见光有改善感觉、提高情绪、驱散忧郁等功效,对预防“冬季抑郁症”大有益处。红外线有强烈的热效应,可使深层组织温度升高,血管扩张,血流加快,从而促进新陈代谢。紫外线有较强的杀菌能力,能使皮肤里的去氢胆固醇合成为维生素D_3,促使骨基质钙化和骨骼发育,帮助钙、磷吸收,可有效预防小儿佝偻病(软骨病)、老年性骨质疏松。再者,紫外线照射能促进新陈代谢和造血功能,促进细胞增生,消炎镇痛,并增加肌肉关节的活动性。另外,紫外线还能激活体
Modern science has confirmed that many rays of solar radiation include visible light, infrared light, ultraviolet light and rays. Sun shines on the human body, the visible light to improve the feeling, improve mood, disperse melancholy and other effects, to prevent “winter depression” a great benefit. Infrared has a strong thermal effect, deep tissue temperature can be increased, blood vessels dilate, blood flow, thereby promoting metabolism. Ultraviolet light has a strong bactericidal ability, can make the skin to dehydrogenation of cholesterol synthesis of vitamin D_3, to promote bone matrix calcification and bone development, to help calcium and phosphorus absorption, can effectively prevent pediatric rickets (Rickets), senile osteoporosis . Furthermore, ultraviolet radiation can promote metabolism and hematopoietic function, promote cell proliferation, anti-inflammatory analgesic, and increase muscle activity. In addition, ultraviolet light can activate the body
