This is indeed very interesting. I didn't know anything about positive or negative ions. I thought the "feel good" effects from Niagara Falls was due to the magnificent beautiful of the falls itself. I do know that I felt high just looking at it.Television and computer equipment emit something called positive ions. These are opposite of negative ions, which are those things in the air resulting from molecules hitting together in such surroundings as the ocean or Niagara Falls. There are more negative ions at Niagara Falls than anywhere else in the U.S. because of all the negative ions formed from the Falls. Negative ions produce the "feel good" effects such as those you experience before a thunderstorm. If you've been to the Falls, you know the natural high you get just by being there. Positive ions are exactly opposite and can lead to depression and unhealthy feelings.
Oh no maybe this is the reason why I haven't been sleeping well lately. Since its summer here and there's no more class, I've been spending more time in front of the screen. I guess I'll just have to adjust my computer usage schedule so that I won't be tempted to use it for the rest of the night.With the computer, it could be that it is wreaking havoc with her inner circadian rhythms. There have been studies done that show trying to go to bed right after signing off a computer will result in difficulty sleeping.
A friend of mine swears that she feels more healthy when she spends less time in front of a TV or a computer. She isn't necessarily more physically active (she's an avid reader) yet feels better. Why do you suppose that is?
^ I think that about sums it up, honestly.Television is like junk food for the mind.
