Michael Breus, PhD: First of all, you should probably be looking at what your children are looking at on the Internet anyway, whether it's video games or things of that nature.I usually recommend parents to have times for the TV, times for the computer, and not to go past those times, and to really limit that access.Just sitting in front of a screen and the light that is produced from that screen actually has been shown in one Japanese study to affect the child's circadian rhythm.
Narrator: Really? In what way?
Michael Breus, PhD:
Well, what it can do is it can actually throw off the circadian rhythm.They found with laptop computers with both adults and I want to say it was high school age kids that they found that it actually made them stay awakebecause light in front of them doesn't produce the melatonin during that portion of the night.
