Blue Screen vs. Lethe

If this is true—and I think it is up in the air whether this is pure quackery or sound science—it would explain a lot here. There are many people who complain of the same problem, being tired and not being able to fall asleep. Virtually everybody uses a computer a night to read, watch movies or TV, etc. It’s sort of a chronic thing. I had always attributed to general stress and vague apprehension.

This is a big, long article in CNN that doesn’t seem have much science to it.  Theoretically, the light emanating from electronic screens is different from the light from a lamp that bounces off a paper book or a nonglowing screen like the Kindle. Much is made of blueness.
