Question:

I read your information about light therapy and negative ion therapy. What about Himalayan Salt lamps for negative ion production? Is it effective? What are the recommended amounts? It's pretty and that's relaxing, but it doesn't counter my husband arguing against it. I'd like numbers please. Tell me anything I should know. Thanks

A myriad of elements and molecules can be ionized, and in the case of salt lamps we are not talking about negative air ionization, which produces superoxide (charged oxygen). There is no clinical evidence for the effectiveness of salt lamps in treatment of depression. It's commercial hype, pure and simple. This time, you husband's right!
