User:Carolfrog/Salt crystal lamps



Salt crystal rocks are natural formations that are used in lamps and candles. They are sold as natural air ionizers, and are believed to improve the air quality in a room by enriching the air with negative ions.

Mined in Europe and Asia, salt crystals emit a soft glowing light and are hand-carved. Many believe that heated salt crystals' emission of negative ions into the air gives the feeling of being on the beach, on a mountain top, or near a waterfall.

Neil Nedley has written that "...the introduction of negative ion generation increased the subjective rating of alertness, atmospheric freshness, and environmental and personal warmth. Fresh country air has negative ions that have been demonstrated to both treat and prevent depression."
