Sunlight also contains blue light, and it is vital during the day. It’s what helps to keep us awake and alert, and it’s an integral part of how sleep cycles work.
But exposure to blue light at night is a bad thing, as it effectively tricks your brain into thinking that it’s still daytime. It suppresses the secretion of melatonin, a hormone that is produced at night and prepares the body for sleep.

Its impact is so great, in fact, that another study even suggested that having a blue LED shining from a car dashboard would be an effective way of preventing drivers from falling asleep at the wheel.
