WebStudies have been showing that by reducing the effects of positive ions on your brain the result is a normalization of your body’s level of serotonin. Negative ion therapy is a proven method of an overall reduction in the presence of positive ions in your body. A normalized level of serotonin will not only lead to happier moods, but better sleep. WebIn muscle cells, nerve endings release calcium ions, which bind to activator proteins. The activator proteins initiate the complex process of muscle contraction and allows your muscles to move. Without calcium, your muscles would not be able to contract and relax.
