Natural salt crystal has been credited with a range of curative powers, from air purification to migraine relief to protection against airborne germs. Mined in the foothills of the Himalayas, where they have absorbed mineral elements that enrich them and imbue them with different colors, salt crystal lamps release healing negative ions into the air when turned on. Like the energizing negative ions released in the natural settings of mountains, waterfalls, or beaches, the negative ions emitted by these lamps increase oxygen flow to the brain, helping to alleviate depression, relieve stress, and boost daytime energy. These ions also naturally counteract the effects of the electromagnetic waves we are bombarded with from appliances like televisions, computers, and air conditioners. Salt crystal lamps have also proved to protect against airborne germs and can reduce the symptoms of allergies, sinus problems, “brain fog,” and insomnia.
