Salt lamps are said to provide health benefits because they are “natural ionizers,” meaning they change the electrical charge of the circulating air.
Ions are compounds that carry a charge because they have an unbalanced number of protons or electrons.
They are produced naturally in the air when alterations occur in the atmosphere. For example, waterfalls, waves, storms, natural radioactivity and heat all produce air ions.
It’s suggested that Himalayan salt lamps may produce ions by attracting water particles that evaporate off as a salt solution when heated by the lamp, forming mostly negative ions. However, this theory has not yet been tested.
Currently, it’s unclear whether salt lamps produce ions in meaningful amounts, if at all.
