Indoor environments, city living, cars, exposure to electronic devices, EMF’s (electromagnetic fields) and environmental pollution all result in increased positive ions in the body, tilting the ratio of ions towards the positive. This lack of enough negative ions results in a physiological imbalance, which may have detrimental health consequences. Too few negative ions in the body can cause a number of diseases. Some of the health problems associated with an imbalance of ions in the body include: anemia, allergies, shoulder pain, lumbago, rheumatism, neuralgia, headaches, kidney problems, imbalanced autonomic nervous system function, insomnia and fatigue.
