just an alternative source of pollution. Today, light pollution is mainly sub-three categories: BAI Liang pollution, pollution of artificial daylight and natural lighting. Recently, more American scientists pointed out that the world has 2 / 3 of people living in the light pollution inside. Ranging from light pollution affects people's circadian rhythms leading to endocrine disorders, weight affected the mood, trigger depression.

Office is the light pollution in the worst-hit

general, affecting the natural environment, to human beings live a normal life, work, play, rest an adverse effect on damage to the human ability to observe objects, causing discomfort and damage to human health, a variety of light, can be classified as light pollution. Today, light pollution is mainly sub-three categories: BAI Liang pollution, pollution of artificial daylight and natural lighting. Into a block of glass curtain wall, glazed brick interior, polished shiny marble floors … … the decoration elegant offices, light pollution is often the hardest hit. Building materials and paint decoration, reflection of light are mostly Ming Huang Bai Liang, eye-catching eye-hyun. Liang Bai environment in the people who work long hours, retina and iris are subject to varying degrees of damage. In other words, eye Suanse fatigue, which is likely to have an office environment, “credit.” Over time, dizziness upset, loss of appetite, depression probably will be at her door. Artificial daylight, we are no strangers. Night under the city, neon lights, shop license bright, large body mass of the buildings were set off beam-beam light. In short, the night has been forgotten in the pile of paper and therefore, only the artificial daylight. Such a “Sleepless Town” affect people's circadian rhythms, it was hard to sleep, but also will affect the efficiency of the next day. Philadelphia Lepidoptera entomologist Jeff Kennett  Folang Ge long known that, due to a misleading light, moth often miss the opportunity to cross-Huan.

lighting is also a “drug”

night work for women with non-night work than women, higher breast cancer risk Liu Cheng; night longer to reach the light The higher the intensity, the greater the likelihood illness. In short, reversal day and night, night owl type of work, not only was not conventional, but also unhealthy. The workplace during the day should be orderly, sound and color at night nor Yong: access to commercial reception, luxury clubhouse. Apart from drinking late at night aside, brilliant success, it faint humor of all kinds of lights, on the people-unfriendly. This is the Intense Pulsed Light pollution. Clubs where black light, rotating lights, fluorescent lights, strobe color constitute a phototherapy light pollution. Black light intensity of ultraviolet light produced by the UV rays than too much stronger on the harmful effects continue longer. Prolonged exposure, may induce nosebleeds, tooth extraction, cataract. Strobe light dazzling color, is not conducive to eye, and interfere with central nervous system, people dizziness, skin cells, accelerated aging, and even nausea and vomiting, insomnia and other symptoms, leading to sub-health. The recent studies have shown that phototherapy pollution also may endanger mental health. From this perspective, the light is indeed the destruction of human health, “STALKER.”

“Light is a kind of drug. abuse of lights, is hazardous to health.” This time the macro theory of prophecy is the United States Texas Health Science Center endocrinologist Russell  Reiter (Rus-sell Reiter) said, . As melatonin researchers, he found that night, shining light on the retina would reduce melatonin generation. This hormone, it is an important regulator of circadian rhythm of the material.

night, too much light exposure may also lead to depression. Locked up in a 24-hour room brightly lit mice, harder than the normal cycle of light and shade of light similar, showing more symptoms of depression. Although the study with rats to study the object, but the researchers believe that the result is also applicable to humans.

selected pairs of lamps using less computer

annoying is that human beings rely on in this bright world. Therefore, the complete elimination of light pollution, equivalent to about one hit 250 yards outside the golf hole, there is little chance. We can only minimize light pollution hazards. Light pollution prevention and control, and many more on prevention. Selection of appropriate lighting, we will be unfairly treated “windows of the soul.” Selection of the most common incandescent or energy-saving fluorescent lamp, still a controversial issue. Incandescent lamp is the incandescent light bulbs as early as in 1906 by the Edison Manufacturing. The light closest to natural light, ie sunlight, which is relatively more long-wave. Of human evolution so far, the adaptation is precisely this light. Fluorescent lamps (ie fluorescent), through the gas discharge principle, issued by a non-continuous spectrum, short-wave is relatively large. In other words, when compared with the incandescent lamp, in the three color vision pathway effect on the fluorescent lamp is no doubt unusual.

fluorescent luminous efficiency, brightness, large, energy-saving long life. So far, it is still within the working environment within the framework of the world's leading light. Last year, the European identification of emerging and new health risks of the Scientific Committee (SCENIHR) in the report that the fluorescent lights may cause health risks are only issued by the UV and blue light. UV hazard goes without saying that Blu-ray is caused by a short wavelength. It is reported that, if at close range (less than 20cm) work long hours under fluorescent lights, skin and retina may be subject to UV damage. However, a long long time to count, there is no precise answer. Perhaps the basis of visual comparison Kaopu fatigue. Computer, television use should be moderate. Japan, a study found that: If you face a long day, 9 hours or more computers, more likely to suffer from glaucoma others twice, while owners of myopia has long been facing the computer, but also a high risk of glaucoma.
