What Are Salt Lamps and How Do They Work?

There are great benefits to owning a Salt Lamp. We usually get asked how do they work. Salt lamps do not generate negative ions themselves. They are "hygroscopic," which means that they attract moisture... humidity... airborne water molecules; it is a natural property of sodium chloride also know as salt. Since they do not generate the negative ions, they need a heat source (in this case, heat from an incandescent bulb) to accelerate evaporation, which does produce negative ions. In more humid regions, an unlit salt lamp will eventually "cry," even creating puddles of water at its base. It is this evaporation that generates the negative ions, which are beneficial to our health.
