Himalayan crystal salt lamps and plates are said to create anions (negatively charged ions) in the air. Since pollution and the use of electrical equipment create potentially harmful positively charged ions (cations) in the air and cause air quality to deteriorate, using a salt lamp helps counter the cations. This natural ionisation helps avoid the physical and mental harm created by the 'electric smog' around us.
Salt lamps can be used either with electric bulbs orcandles depending on the model, both emitting a soft,golden light that lends visual appeal to a room. Not onlydo they look good, they also function as natural aircleansers. Heat from the bulb or candle make the crystal salt emit negatively charged ions, which enter the air andneutralise the positively charged ions created by pollutionand electrical appliances. The neutralised ions become heavy and fall to the ground
These lamps are made of natural crystal salt fromunderground mines in the Himalayas. The crystal salt ismillions of years old and has a high mineral content aswell as special properties. The cleansing properties of these lamps are said to help combat illnesses like allergies and asthma. Other sources of anions are waterfalls and the sea; these produce up to 10,000 anions per cubic metre compared to just 100 anions per cubic metre being produced in a city at rush hour time
