There is such a thing as negative ion therapy...that's why I think I feel better at the ocean. But there are room sized negative ion generators. I'm not certain if they work though or if they are just a scam.With falling air pressure, my pain is way high, and my physical and mental energy are way low. I'm curious if anything tends to help with this. If the high level of positive ions is the problem, is there such a thing as negative ion therapy?
