When illuminated, salt crystals emit a soft glowing light. Some believe that heated salt crystals emit negative ions or positive energy waves into the air. There is, however, no scientific evidence that salt lamps actually give out a measurable amount of “negative ions”, nor is there any evidence of any health benefits from the lamps
How Do Rock Salt Lamps Work?
The heat from a lighted salt lamp attracts moisture. The evaporation of water through salt emits negative ions. How many negative ions a salt lamp or salt candle holder can release depends on its size and how warm a match-lit candle or electric light bulb makes it. A night-light sized salt lamp would be effective for an office cubicle. Naturally, the larger an area means a larger lamp is needed so that more more negative ions will be emitted.
