Many people are aware of the benefits of negative ions for better health. Negative ions are essential for our health and wholesomeness. The freshness of the air after a thunderstorm on a mountain top, or by the seaside, is due to the high concentration of negative ions in the air. On the other hand, one feels not very well in highly polluted areas, artificially air conditioned premises, or in hot dry wind weather conditions, because of insufficiently low negative ion balanced and therefore high proportions of positive ions. A positive ion in the air is a molecule that has lost its electrons through process of air pollution. In Fresh Country side Air we find up to 3,000 negative ions per cubic centimeter (the size of a sugar cube). Near strong surf or close to a water fall up to 10,000 negative ions can be found. How ever the number of negative ions in major metropolitan cities at rush hour does not even reach to 100 negative ions per cubic centimeter.  Most of our life we spend in closed areas. The air is electrically charged, it consists of many particles, which in a certain relationship are positively (pollutions) or negatively (minus-ions) loaded. The latest scientific research says that the ion-balance is very important for our health and well-being.
