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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
