As well as being beautiful, salt lamps release negatively charged ions. These negative ions neutralize positively charged ions given out by computers, televisions, power grids etc. Negatively charged ions create an environment that is similar to being near the sea or a waterfall and help to purify the air. The salt lamps should be lit at all times as they give off more negative ions that way. By using Salt Crystal lamps, we can easily improve our environment, not only thorough the ionizing effects of the lamp but through the beautiful light they cast in a room! Place them near your television or computer area.
