Do claims that Himalayan Salt Lamps produce negative ions when lit with an incandescent bulb have any science to back it up?

  • Dr. Mercola sells them so the claim seems notable enough to me (and a good target for skepticism). My very quick research on this indicates that they do produce negative ions by means of the salt attracting water and then the lamp evaporating it however the quantity of negative ions is near negligible.

  • do "negative ions" have a positive (or any) effect?

  • How would you produce a negative ion without producing a positive ion? Hence, how does one test whether any effect would be due to the negative ions alone?

  • Without knowing the precise mixture of salts and their interaction with the radiant energy of lamp, it's difficult to predict if any negative ions are produced, and positive ions swallowed up by some concomitant reaction. The field is rife with pseudo-science and lack of peer-reviewed studies that support their benefit anyhow. Feb 26, 2014 at 2:20
