居室环境的好坏,直接影响着人体的健康与寿命,不可忽视。 居室光照 阳光对人体健康十分重要,国外有句谚语“阳光不到的地方是医生常去的地方”。在一切光照中,对人体健康最为有益的首推太阳光,因它除可见光外,还有红外线、紫外线。红外线有着很强的穿透力,对人体的作用是热刺激,引起反射性扩张,使血液加快,促进机体的新陈代谢。接受适当的紫外线照射,在儿童可防佝偻病,老年人可减轻骨质疏松;紫外线还有杀菌、消毒作用。随着城市高楼大厦的兴建,建筑物密集,太阳光照不足的影响在增加,因此,要注意用其它方式加以补偿。比如经常打开门窗,让阳光折射或反射;经常把被、褥放到阳光下曝晒,以达到杀菌、消毒目的,科学地使用灯光等非自然光,也可促进人体健康与防治某些疾病;长时间伏案工作要多到室外散步,多接受阳光,尽量采用光谱色较全面的“日光色”荧光灯,少用“白冷色“荧光灯。 Room environment is good or bad, a direct impact on human health and life expectancy, can not be ignored. Living room sunlight is very important to human health, there is a saying abroad that “where the sun is not frequented by doctors.” In all light, the most beneficial to human health devaluation of the sun, because it in addition to visible light, there are infrared, ultraviolet light. Infrared has a strong penetration, the role of the human body is stimulated by heat, causing reflex expansion, so that the blood to accelerate and promote the body’s metabolism. Accept appropriate ultraviolet radiation, children can prevent rickets, the elderly can reduce osteoporosis; UV also sterilization, disinfection. With the construction of tall buildings in cities, the buildings are dense and the impact of inadequate sun light is on the rise. Therefore, we should pay attention to other ways to compensate them. For example, often open the windows and doors, so that the sun refracted or reflected; often put mattresses exposed to the sun, in order to achieve sterilization, disinfection purposes, scientific use of light and other unnatural light, but also can promote human health and prevent certain diseases; Work more desk to outdoor walking, more to accept the sun, as far as possible the spectral color more comprehensive “daylight” fluorescent, less use of “white cool” fluorescent.
