We spend most of our lives in enclosed places whether it is in the home, or office. Our frame of mind and physical condition depend on the quality of the air that we breathe. Air is electrically charged, which means it contains indefinite proportions of positively charged molecules (positive ions) and negatively charge molecules (negative ions). Studies have shown that their balance is required to create a good mood. 

The environment we live in is full of positive ions, which makes the air is more polluted. These positive ions are being discharged by electrical appliances, high voltage networks, heating and cooling plants, radio and television transmitters, computers, TV sets and even vacuum cleaners. 

The Himalayan Salt Lamps are efficient emitters of negative ions that can improve the air quality.
