Nighttime blue-light LEDs cause health problems, AMA warns

The American Medical Association (AMA) has issued a warning about the human health and environmental impacts of LEDs that emit excessive blue light. A new AMA-approved report backs six-year-old findings of the International Dark-Sky Association (IDA) about the negative consequences of the global movement to LEDs as the preferred outdoor lighting technology. Travis Longcore, an architect and biologist at the University of Southern California, said in an IDA statement about the AMA's warning, “Policy makers, government officials, and the American public now have the science and the imprimatur of the AMA to insist that LED installations be designed to reduce impacts on wildlife and human health.”
