Often referred to as ‘the vitamins of the air’, an Ion is a particle which has electricity. Ions are molecules that have gained or lost an electrical charge. They are created in nature as air molecules break apart due to sunlight, radiation Ions when you last set foot on the beach or walked beneath a water fall. While part of the euphoria is simply being around these wondrous settings and away from the normal pressures of home and work, the air circulating in the mountains and the ocean is said to contain tens of thousands of Negative Ions. At Yosemite Falls, you’ll experience over 100,000 Negative Ions per cubic centimeter. On the other hand, if you’re on an LA freeway or in your office, you will experience under 100 negative Ions or maybe even none. After a rainstorm there are lots of Negative Ions in the air.
