Research has found that exposure to blue light suppresses the production of the sleep hormone melatonin more than any other type of light. (Image credit: Ng Wei Keong | Shutterstock.com) Fluorescent bulbs and light-emitting diodes (LEDs) have taken over lighting because they are more energy ...
Install blue light-filtering appson smartphones, tablets, and computer screens. They filter a lot of blue light from reaching your eyes without making it harder to see the display. Swap light bulbs. LEDs give off more blue light than fluorescent bulbs. And both emit more blue light than ene...
Firstly, their overall brightness uniformity is better than that of pearl white screens, meaning that there won't be darker corners with a brighter center, which also means that using a matte white screen reduces the likelihood of color bias (one side leaning blue and the other red). The se...
When the ultraviolet light strikes atom of the phosphors (shown here as white dots), it excites their electrons in just the same way that the mercury atoms were excited. This makes the phosphor atoms unstable, so they give off their excess energy as photons—which, this time, happen to be...
OLED displays are made up of red, green, and blue LEDs, but the different colors have different lifespans. Speaking more technically, the issue is that blue LEDs have significantly lower luminous efficiency than red or green pixels. This means that a blue LED needs to be driven at a higher...
How Does Light Pollution Affect Your Health? You need darkness to live a healthy life. Before the invention of artificial light, humans were adjusted to a natural 12 hours of daylight and 12 hours of darkness. This cycle is part of your circadian rhythm, your body’s internal "clock" that...
However, sometimes it’s a little challenging to identify when buds are ready since buds can look different at harvest time depending on the strain and how they were grown. Here are pictures of some different cannabis buds that are ready to harvest! A bud is ready to harvest when most of...
“We had observed that all of the diseases that were associated with chronic circadian disruption were also linked to inflammation, which is a product of the immune system. However, a deep understanding of how the clock controls the immune system, in cells or in organisms, didn’t exist. Thi...
