Light Pollution and Human Health. Recent studies also show a connection between reduced melatonin levels and cancer. Reduction of melatonin production in the body; hormone responsible for growth in the body. [CDATA[ The effects of pollution can be seen every day, all around you. Migraine. Nighttime exposure to artificial light suppresses melatonin production. While the effects on humans may be less noticeable, light pollution indeed has a measurable effect on us. having to do with biological cycles recurring at 24-hour intervals. Alteration of the biological clock. moths that are attracted to incandescent lanterns and are killed by the heat). One study looked at how marine animals responded to brightly lit panels submerged under water off the coast of Wales. For information on user permissions, please read our Terms of Service. Light pollution has been, traditionally, seen as concentrating near or within high population areas, due to the high use of nighttime lights along streets, public areas, residences, and businesses. Light pollution has been, traditionally, seen as concentrating near or within high population areas, due to the high use of nighttime lights along streets, public areas, residences, and businesses. Light pollution is worse on cloudy nights, because upward-facing light is reflected back down to the surface. Light pollution disrupts circadian rhythms for both humans and animals alike and may even contribute to the development of cancer. Gina Borgia, National Geographic Society More than 80 percent of the world’s population, and 99 percent of Americans and Europeans, live under sky glow. Several studies have linked increased breast cancer risk to women exposed to unnatural levels of light at night, possibly through suppressing a hormone called melatonin. Adult and hatchling sea turtles are drawn toward lights along the beach, thinking they are heading toward the moon. People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. introduction of harmful materials into the environment. Blue light, in particular, has been shown to reduce levels of melatonin in humans. The whole world needs to know about pollution and take steps to reduce it, because the negative effects of pollution are serious and potentially fatal. But they also tend to produce more blue light.”. Light pollution is any artificial light that is intrusive, unsafe or wasteful (see References 1). We present quantitative criteria to evaluate the lamps based on their spectral emissions and we suggest regulatory limits for future lighting. Air pollution can have a serious heath impact on humans. We performed analysis of the spectra of common types of lamps for external use, including the new LEDs. Research suggests that artificial light at night can negatively affect human health, increasing risks for obesity, depression, sleep disorders, diabetes, breast cancer and more. After all, it is just light, so how harmful can it be? Since light pollution is an artificial effect caused by humans which does not occur in nature at scale, chances are that ecosystems may be confused and affected in an adverse manner. Light pollution is excessive, misdirected, or obtrusive artificial (usually outdoor) light. There are three other kinds of light pollution: glare, clutter, and light trespass. Effects of Noise Pollution on Humans Health and Animals. For example, one structure of light pollution is light encroaching; in this form of light pollution, not needed light extends without cause—or trespasses—into somebody else’s space.
