Lights Out? The Dangers of Exposure to Light at Night

A panel of world experts discussed "Light Pollution and its Ecophysiological Consequences" and shed light on the extent of the dangers and harm that night-time artificial lighting causes, emphasizing that it is the short wavelength illumination that we have come to know as "eco-friendly illumination" that is causing the most harm (primarily LED lighting).

"The most important thing for us is to raise awareness of the dangers of artificial light at night and we have already come a long way now that the American Medical Association (AMA) recently announced its new policy recognizing adverse health effects of exposure to light at night and encouraging further research into the matter," said Prof. Abraham Haim, a leading authority on light pollution, who coordinated the 21st International Congress of Zoology (ICZ) that was held last week at the University of Haifa, Israel.

The participants were in full agreement that exposure to light at night affects circadian rhythms in nature -- humans, animals and plants -- which when thrown off can result in various illnesses and adverse symptoms.
