A Blue Light Problem

With a huge shift towards LED lighting, human and nature is being subjected to a serious mount of blue spectra.LEDs Magazine shares how it’s leading to harmful effects, including the production of melatonin and animal migration.

The team pointed out detrimental effects on the production of melatonin among many organisms. Melatonin is a hormone associated with sleep and the circadian cycle in many animals as well as in humans. They also noted that excess artificial light at night, especially in the blue spectrum, is undermining the ability of not just humans but animals to see stars, a detriment for creatures that use stars for navigation. And they wrote that blue wavelengths are undermining the light-determined (“phototaxic”) activities of moths and other insects.
