The Positive Health Benefits of Negative Ions By Jim English

Health Benefits of Negative Ions

Just as positive ions build up in the atmosphere prior to a storm front, negative ions accumulate following a storm. This surfeit of negative ions has long been associated with improvements in mood and physical health. Research conducted in the last decade has begun to support the view that negative ions have a net positive effect on health.

One of the most tantalizing hints regarding negative ions and health surfaced when German researchers discovered a link between catecholamine regulation and lifespan after depriving experimental animals of negative ions. First, researchers at the Goldstein and Lewin Dept. of Medical Research in Stahnsdorf, Germany isolated mice and rats in air-tight, sealed acrylic cases. Next, they filtered the ambient air to remove all negative ions from the sealed cases. Their research led to the discovery that a prolonged deficiency of negative ions led to an accelerated rate of death for the experimental animals. Examination of the animals led researchers to conclude that the results strongly suggest that animal death is related to disturbances in neurohormonal regulation and pituitary insufficiency. (23)

Researchers at the Russian Academy of Sciences in Moscow discovered that negative ions are able to help protect the body from induced physical stress. When the researchers immobilized rats and exposed them to negatively charged air ions they discovered that the ions prevented the development of pathological changes characteristic of acute stress that are observed in untreated rats. The protective action of negative air ions was observed in all the experimental animals independently of their types of behavior. (24)

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.” (25)

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).” (26)


While progress has been made in some areas of air pollution, such as reductions in emissions of lead, sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O3), air pollution, particularly from particulates, remains a serious health problem. In addition to damaging the lungs and heart, air pollution is now recognized as being especially harmful to children, the elderly, and select sensitive populations, such as those afflicted with diabetes, cardiopulmonary diseases and other debilitating illnesses.

To address air pollution-related health problems a growing number of people are using personal and home air filtration products that generate negative ions to charge and precipitate airborne particulate matter for removal to create localized zones of improved air quality.

Consumer devices that utilize 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. Negative ions have long been attributed to improvements in mood and physical health. Research supports the view that negative ions have a net positive effect on health, including improved mood, stabilized catecholamine regulation and circadian rhythm, enhanced recovery from physical exertion and protection from positive ion-related stress and exhaustion disorders.

Dr. Svante August Arrhenius, a Swedish chemist who received the Nobel in Chemistry in 1903, discovered that there are full of negative ions near waterfalls and forests. That is why the air is so fresh. Thus, he formulated his theory of electrolytic dissociation, or “ionization.”

At the turn of the 20th century, Nobel Prize Winner in Physics, Dr. Phillip Eduard Anton Lennard, confirmed that negative ions are found in very high density in the basin of waterfalls where we feel especially refreshed and re-energized.
Dr. Jacob, Professor of Physiology with the Public Sanitation Institute of Harvard University acclaims negative ions as “Vitamins of the Air”. As the largest organ, our skin absorbs 85% of charged particles from the surroundings constantly. Long term exposure to an environment full of smog, chemicals, and positive ions adversely affects our health. The invention of healthy fabrics makes it possible to enhance our health in an optimal and portable environment, and to minimize the effects of environmental pollutants so that our bodies can do the work for us!

Irrefutable Scientific Documentation

An article in The New York Times on the seasonal affective disorder (SAD), a condition in which people become depressed and lethargic during the gloomy winter months, positively stated the effects of negative ions on improving mood.
“…sitting in front of a machine that emits negative ions at a high rate for 30 minutes every morning was as effective as sitting in front of a lightbox for the same time.”
In other words, according to the Times report, negative ion therapy improved mood and lessened the depressive effects of SAD.
The science behind negative ion therapy hypothesizes that once the negative ions reach the bloodstream through the lungs, they cause an increase in a body chemical called serotonin – proven to increase energy and stamina levels, to alleviate stress, to improve focus and to lessen the impact of depression.
Impartial studies conducted by the United States Department of Agriculture (USDA) showed that a high concentration of negative ions cuts dust levels by as much as 50%. The same USDA study showed a 95% decrease in airborne bacteria when negative ions were released into the air.
In another study, this one conducted in a hospital in the UK, ionizers (machines that produce negative ions) “dramatically reduced the incidence of infections from [a] resistant hospital bug…in the ITU unit…” (Jolley,The Power of Negative Ion Science)
Negative Ionization Changes Body Chemistry from the same study, “High levels of negative ions are found at the beach, in the mountains, the country, pine forests, near waterfalls and many other places people enjoy – places people…go to be refreshed and renewed. The air in these places creates an effect on human biochemistry.” (Jolley)
We’re all familiar with the rejuvenating effects of clean, fresh air. Even when you simply open a window, that fresh air makes you feel better all over. Why? A burst of negative ions and the subsequent release of the neuro-hormone, serotonin, produces a “good-all-over” feeling. The scientific proof is out there. And, your own experience demonstrates that technology does, indeed, deliver improved health.
