Hello everyone, Firstly, I'm new to this forum and therefore please forigve me if I don't suond as scientific as I should, In any case, I had a question to ask. Many people claim that negative ions are very good for your health as they are supposed to increase seratonin, make you happier and what not. In fact, it's even become a therapy in some parts of the world. In any case here is my question: would it be possible for RF/microwaves to produce negative ions under certain frequencies? Or do all electromagnetic waves only emit positive radiation? Steven
