Crystal Salt Lamps emit negative Ions to their surroundings. The ionization helps combat many of the harsh elements that assail our bodies, causing us to feel unwell. Placement of our salt lamp in an area that one uses frequently can help balance the body, boost our immune system and give back lost energy. Negative ions purify the air, reducing the effects of: Dust, Bacteria, Pet Dander, Odor, Allergies, Asthma, Sinus, Fatigue and even Colds. May also relieve symptoms of Anxiety and Insomnia.
