Due to the hygroscopic (water-absorbing) and photoelectric nature of a heated Himalayan salt lamp, it emits vapor and negative ions, respectively. The negative ions were proven to attract pollutants, airborne particles, and positive ions generated by electromagnetic fields (EMF) emanating from electric devices to the salt lamp, purifying the air and creating a feel-good atmosphere. Exposure to such field were found to go as far as complicate already-existing diseases.
“The amount of time we spend in front of a screen or holding a phone can generate a lot of positive ions, enough to disrupt our emotional state,” says Michael Terman, professor of Clinical Psychology at Columbia University’s Medical Center. Terman explained that equalizing these ions with negative ones enhances the mood and eliminates the stressors that can trigger depressive disorders, irritability, and insomnia.
