Electrical devices (phones, TVs, computer, florescent lightning, synthetic materials and fabrics) give off positive ions in the air [5]; so in a sense, our environment may be over saturated by positive ions, whereas humans need a balance between positive and negative ions to flourish. This imbalance can make us have lower energy, feel crazy, and depressed.⠀

Heated salt lamps emit negative ions that restore and neutralize air quality. One study showed that brain tryptophan and 5-HT (serotonin) metabolism were increased after salt lamp exposure for 14 days in rats [1]. Negative air ions have been significantly associated with lower depression ratings [4], declared an effective treatment of chronic depression [2] and seasonal depression (aka season affective disorder) [3]. ⠀
