Himalayan Rock Salt Lamps are natural ion generators, producing negative ions into the surroundings. Is this a good thing? Negative ions are really good for your health! Negative ions restore and neutralize the harmful effects of positive ions. Negative ions can be used to boost your health. Our offices and homes are loaded with electronic gadgets (televisions, computers, heaters, air-conditioners, laptop, etc.).These gadgets emit loads of positive ions, so keeping a rock salt lamp, where positive ions are disturbing the surroundings, can help in neutralizing the air you breathe.
