Anyone heard of negative ion generators

I heard about some people using negative ion generators where they train to get some benefits. Anyone heard of this?

Supposedly it helps give you more energy or such. It is probably true, seeing I have heard people having problems going to sleep if a negative ion generator was in a room and on.

Anyone ever heard or used one before while training?


On a side note, though, I would think that training with one could be helpful if you are tired or such, but using one all the time might have a negative effect when you are at the game (not having one). Just ideas. Any thoughts on it?

Neg Ion gens clean the air by causing dirt and pollan to fall out of the air. The Ionic Breeze units on infomercials do something like that- pos charge dirt particles first and then Neg to get them to stick to collector plates and they can be bought with a UV light (?) to kill bacteria etc in the air as well. Some people with allergies have noted an improvement. They are a bit expensive but quiet compared to the usual fan-based filters and need no filter replacements. (BTW, UV light purification systems can be added to the water inlet into your house.)
