Not only do these Himalayan rock salt lamps look stunning but they're claimed to have health giving properties too. Himalayan salt crystals release negative ions from their surface when warmed that help to cleanse the air around them. Our modern lives see us surrounded by technology, screens, air conditioners & heaters all of which release positive ions which can result in mental & physical exhaustion. The negative ions released by the salt lamps are believed to produce biochemical reactions that increase serotonin in our bodies helping to alleviate depression, relieve stress & boost energy.
