There are few things lovelier to look at and better for your home environment and health than Himalayan salt lamps. The rich, warm, amber glow of these lamps will illuminate any room—and bring along a large host of other benefits.When heat from the bulbs or candles (there are both electric and wick-lit options) inside of these lamps infuses the Himalayan salt crystals with heat, a chemical reaction takes place. As the rules of chemistry state, when salt is heated, even slightly, it begins to emit negative ions. This process of negative ionic charge in itself is nothing unexpected; what has surprised researchers is the amazing bonding process that occurs when these negatively-charged ions bond with pollutants and other impurities in the air, neutralizing them, and making the air anywhere in range of the lamp as clear as a breeze from the Himalayans.
