Ion therapy

From Wikipedia, the free encyclopedia

Ion therapy uses a special electronic device that generates negatively charged particles. Negative ion therapy has been shown to alleviate symptoms associated with Seasonal Affective Disorder.

Negative ions contain an extra electron, and are created naturally by the sun, wind, and moving water. Such molecules, in high enough concentrations, neutralize odors and make air cleaner.
