For any creature, this damage is again driven by color. According to the report, Led Public lighting(CLASSIC)

"has at least five times more influence on circadian rhythm physiology than high-pressure sodium lamps based on melatonin suppression." For animals, the color and brightness of outdoor lighting are equally meaningful, affecting how birds migrate, If the lightning bug is born, and determine the success rate of the young turtle trying to enter the sea.

Changes in circadian rhythms due to the blue tint of the LEDs may also affect people's hormone levels. A study in 2018 showed that people living in public areas of LEDs have an increased risk of prostate or breast cancer, both of which are hormone-related cancers. The study tracked more than 4,000 patients in Spain and established a link between high-level LED exposure and a doubling of the risk of prostate cancer and a 1.5-fold increase in breast cancer risk.

Despite the increasing risks, there are ways to mitigate most, if not all, of the negative effects of LED public lighting while maintaining an edge. The yellower LED public lighting softens the intensity of the blue light, and the lower intensity lights help the neighbors feel less like night-lit stadiums while still making the street feel safe. Shields on both sides of the light can also help, so light is directed to the ground instead of the surroundings, including through people's windows.
