(January 20, 2009; a LisaBarger.com Q&A) “Do those Himalayan salt lamps really work for cleaning air? Do you think they’re scams?”
I am not convinced that Himalayan salt lamps do anything to make a significant difference in your health. Yes, they’re beautiful but any actual health effect would be, in my opinion, so small that you’d be much better off just using them as a room accessory and purchasing a de-humidifier and an actual HEPA filter.
What Himalayan Salt Lamps Are Supposed To Do
We looked at a few web sites and catalogs selling Himalayan salt lamps and found a variety of claims. Some sites, like IonicSalts.com are very upfront with their “no science” admissions. Others, like Natural-Salt-Lamps.com, go a little further and (in a slightly roundabout way) claim that their lamps produce negative ions that “bring oxygen to your brain”, “boost your immune system” and cure seasonal affective disorder.
How Salt Lamps Work Their “Miracles”
According to claims made on various websites, salt lamps “work” by releasing negative ions into the air. Unfortunately, as this blogger points out, there’s no way these lamps can work as promised.
Is There Any Science Behind This?
While the potential health benefits of bathing in salt waters have been touted for centuries, there is actually some science to back up those practices. In 2000, for example, psoriasis patients were encouraged to bathe in water in which was dissolved salts from the Dead Sea. The patients symptoms improved, no side effects were reported and the patients expressed a “high acceptance” of the therapy.
However, there’s a big difference between soaking in salted water and simply sitting next to a lamp made of salt. Despite seeing claims on several salt lamp web sites of “studies” proving their usefulness, we were not able to find even a single published study on Himalayan salt lamps.
So Are Himalayan Salt Lamps Scams?
It’s not often that I actually pronounce a product an out-and-out scam but I'm doing exactly that here. As beautiful as they are—and I DO have one, by the way—there is just no way Himalayan salt lamps can “clean” your air.
