From the post: Experts have long warned about the dangers of blue light before bed. When exposed via smartphones, TVs, laptops and other devices, our brains suppress the production of the hormone melatonin, which normally makes you feel drowsy. As a result, you feel more alert, making it harder to fall — and stay — asleep. But the link between blue light and sleep is murkier than we thought, said Lauren E. Hartstein, an assistant professor of psychiatry at the University of Arizona. She and other researchers have been taking a closer look at the evidence, which suggests that blue light alone may not be causing poor sleep. And in some cases, screen use could even help you drift off.

Well, Making red light is easier to make than blue light (LED's).

Red light also doesn't fuck your night vision so having a fuck load of blue light at night would really fuck up your night vision and that would suck balls.

Fun random thing. One of the things that is brought up on "how you can tell the universe is moving AWAY from you" is because its all red-shifted, not blue shifted. If something is moving toward you, it will be blue-shifted, if its moving away, it will be red-shifted.

Also, Yep, I chuckled at the joke at the end.

I’m gonna have to lookup red shift and blue shift never heard that.
