Do They "Run Out?"
I bought two negative ion bands in early November, 2011, paying what I thought to be an astronomical price ($30.00 Cdn ea.) for them and wore them faithfully, taking them off at night, and putting them back on daylight hours. And they seemed to work! I spend a lot of my evening at a computer, and I sometimes get headaches from that, but with the bands, those disappeared.
Then, about end of December, the headaches came back. And that got me wondering, does the efficacy of these bands wear off over time? Do they need replacing. Just HOW do they work? I'm still looking into that one.
Reply: Still working on it too Tren - this page is my "thinking out loud" about it.
Common sense would say that anything that emits particles of any sort would eventually run out of particles to emit, and that would seem to be the case here, given the stories I have personally heard about the decay of ion emissions over time.
It would therefore seem that the highest benefit ought to be gained from starting with the highest level of emissions - assuming that thos emissions are also maintained over time, of course.
