Negative ions are oxygen ions that have an extra electron attached and naturally occur in nature. They are produced through water molecules, which is why they are in such delightfully abundant supply near fresh, flowing water stores such as rivers, streams, oceans and waterfalls. Also, just as positive ions build up in the atmosphere prior to a storm front, negative ions accumulate following a storm.We all know that taste in the air and feeling you get at the beach, near a waterfall or after a storm. This is your body being saturated by the positive natural benefits of negative ions.
One of the most tantalizing hints regarding negative ions and health surfaced when researchers at the Goldstein and Lewin Dept. of Medical Research in Stahnsdorf, Germany discovered a link between catecholamine regulation and lifespan after depriving experimental animals of negative ions. This research led to the discovery that a prolonged deficiency of negative ions led to an accelerated rate of death for the experimental animals.

Another clue to the role of negative ions in health comes from Russian research conducted at the Institute of Theoretical and Experimental Biophysics of the Russian Academy of Sciences, in Pushchino, Russia. Researchers found that exposure to negative ions increased levels of the protective antioxidant enzyme superoxide dismutase (SOD) in mammalian erythrocytes. The researchers also discovered minute amounts of H2O2 (hydrogen peroxide), writing, “The primary physiochemical mechanism of beneficial biological action of negative air ions is suggested to be related to the stimulation of superoxide dismutase activity by micromolar concentrations of H2O2 (hydrogen peroxide).”

British researchers at the Centre for Sport and Exercise Sciences in Liverpool exposed male subjects to negative ions and measured physiological responses, including body temperature, heart rate and respiration, while at rest and during exercise. Negative ions were found to significantly improve all physiological states, particularly during rest. Most important was the finding that negative ions are “biologically active and that they do affect the body’s circadian rhythmicity.”

Negative Ionisers have been available since the 1930's and have been used throughout Europe, the Middle East, the Orient and the former Soviet Union in medical and general applications. Consumer devices that utilise negative ion-generating technology have been shown to eliminate airborne pollutants, dust, cigarette smoke, pet dander, pollen, mold spores, viruses, and bacteria from the air.
What is an air ionizer?
An air ioniser, also known as a negative ion generator is a useful item to have in the house as they simultaneously purify and remove allergens and dust particles from the air. In addition, these devices continually refresh the air, neutralise odours and improve air quality with air filter technology.
How do air ionizers work?
Particles, known as ions, attach to oxygen in the air to create a negative charge. Once it becomes a negative ion, the molecule attaches itself to pollen, dander, dust and odor to create a cluster. Air ionizers are capable of drawing these clusters into an air filter, which can be easily cleaned or replaced as required.
Negative Ion Generators
Not all negative ions generators are the same. Some have been specifically designed for therapeutic purposes and are sometimes referred to as Negative Ion Therapeutic Medical Devices.
Included on the Australian Register of Therapeutic Goods (TGA) are these Australian designed and manufactured Negative Ion Medical Devices.
