The ratio of negative to positive ions is criticall, because negative ions are able to neutralize the harmful effects of positive ions. At the beginning of the 20th century, the ratio in the atmosphere was 1.2 negative ions for every positive ion. However, in recent years, the ratio has reversed and now there are 1.2 positive ions for every negative ion. This is due to air and water pollution, electromagnetic fields, and other factors.
Positive and negative ions are also in our bodies, and the ratio of ions in the air we breathe influences the ratio in our bodies. Ions enter the body through the lungs (respiration) as well as through the skin - especially through meridian (acupressure) points, which have weak electronic resistance. Then they travel through the blood and lymphatic systems to cells in the body.
2% of the oxygen we breathe turns into free radicals in our bodies. When these free radicals combine with free radicals produced by other sources (such as heavy metals, chemicals, bacteria, viruses, and positive ions), they become more harmful. Negative ions work to prevent oxidation by neutralizing the free radicals in cells. As a result, cells are revitalized, and immunity and resistance are strengthened. Negative ions also work to balance the autonomic nervous system and improve gastrointestinal function. They can relax the mind and body, giving deep sleep, increased metabolism, stabilized appetite and blood pressure, enhanced recovery from physical exhaustion, and help one feel refreshed. Negative ions are essential to overall health.
