Medical experts issue warning about street lights
The American Medical Association (AMA) has just adopted an official policy statement about street lighting: cool it and dim it. The statement, adopted unanimously at the AMA's annual meeting in Chicago on June 14, comes in response to the rise of new LED street lighting sweeping the country. An AMA committee issued guidelines on how communities can choose LED streetlights to "minimize potential harmful human health and environmental effects."
There are two basic issue at hand. First, new, "white" LED lighting, which have a color temperature of between 4000K and 5000K, can cause discomfort and glare. This is because the light is concentrate and has high blue content, which can cause severe glare and force pupillary constriction. Second, these lights can impact human circadian rhythmicity, affecting our sleeping pattern. And, actually, it's not just human sleeping patterns at risk—wildlife migratory patterns are being disrupted as well.
