Improve the environment in your home with a Himalayan Salt Lamp. As well as being beautiful, salt lamps release negatively charged ions. These negative ions neutralize positively charged ions given out by computers, televisions and other electronics normally found in homes. Negatively charged ions create an environment that is similar to being near the sea or a waterfall and are what give the air in these areas that fresh feeling. The salt lamps should be lit at all times as they give off more negative ions that way.
