Scientists have found links between certain types of light and the effects on humans and our tiredness. Specifically blue light similar to the light we experience when seeing a blue sky can help suppress certain chemicals that make us feel drowsy such as melatonin. By backlighting computers with blue LED researchers found that users who spent five hours at these screens produced less melatonin and were overall less drowsy. It can be concluded that light exposure, and the type of light that humans experience can be very influential to mood.
- Researchers are seeking to manipulate the body’s circadian rhythms to help us become more productive
- Office designers are being advised to take types of light and their effect on employees into consideration when creating office spaces
- To promote our natural cycles, exposure to light should be minimized at night and during sleep
“Multiple tests now show that humans are particularly sensitive to blue light — basically, the main color we see when we’re outdoors.”
