Staring at the computer screen will hurt your sleep

I've noticed that if I work on the computer right up until I go to bed, I have trouble sleeping. I'm not the only one. This blogger's doctor told him to not stare at a computer screen at night for that very reason.

Why my doctors told me that if you are going to spend inordinate amount of time in front of a computer screen at night, you might have tough time going to sleep. The screen-flicker makes your eyes and your mind think it is day time, hence you have trouble sleeping.

I also find that the things I do on the computer are not relaxing. It's not like reading a story in a book.
