Following are excerpts from just some of the published research on negative ions.

Study conducted by Surrey University at the Norwich Union Insurance Group showed that negative ionization could improve task performance by as much as 28% and in general, the more difficult the task, the more improvement could be accomplished. The study also showed a 78% reduction in the incidence of sickness and headaches amongst staff.

At the University of Pennsylvania’s Graduate Hospital and at the Northeastern and Frankford hospitals in Philadelphia, Dr. Kornblueh and his associates administered negative ion treatment to hundreds of patients suffering from hay fever or bronchial asthma. Of the total, 63% experienced partial to total relief.

Dr. Kornblueh also studied brain-wave patterns and found evidence that negative ions tranquilized persons in severe pain. In 85% of burn cases treated with negative ions, no pain-deadening narcotics were needed. Dr. Robert McGowan says “Negative ions make burns dry out faster, heal faster and with less scarring.”

Dr. Albert P Krueger and Dr. Richard F Smith at the University of California discovered that cigarette smoke slows down the cilia (tiny hair filaments that line the bronchial tubes and trachea or wind pipe), impairing their ability to clear foreign, and possibly carcinogenic substances from the lungs. Negative ions were found to reverse the effect of the smoke and increased the ciliary’s beat.

A study conducted by the U.S. Dept. of Agriculture found that ionizing a room led to 52% less dust in the air and 95% less bacteria in the air.

In the Journal of Applied Microbiology, the use of negative ions was found by scientists to reduce the presence of airborne viruses by about 40%. A study featured in the 1987 issue also showed the negative ions are free from any adverse side effects.

In a study conducted by Columbia University, negative ion treatment was proved to be as effective against SAD (Seasonal Affective Depression) as antidepressants such as Prozac and Zolof, but without the side effects of these drugs.

After World War II, the Russians extensively studied the relationship between negative ions and physical performance. In each test, the group that trained in facilities, and stayed in quarters high in negative ion concentration showed tremendous improvements in performance in comparison to the control group. (M. Jokl, Prague).

Journal of Aviation, Space, and Environmental Medicine (Aug. 1982 p822 – 823) re study conducted at the Air Force Aerospace Medical Research Laboratory at Wright-Patterson Air Force Base in Ohio.
Summary of Results: “Subjective perceptions of Psychological state, using individual ‘normalcy’ as standard, reflected significant differences between control and negative ion exposure groups. Prominent perceptions reported were reductions in irritability, depression, and tenseness, and increases in calmness and stimulation associated with ion exposure. For Psychological state, negative ion exposure appeared associated with feeling better about self, less sensitive, and more responsive or innervated (energized).”

In a six-month study conducted in a Swiss textile mill, a total of 22 sick days were lost by employees working in the room in which the negative ionizer was operating. In the room where the negative ionizer was not operating, a total of 64 days were lost to sickness. During a month long flu epidemic, the first group lost a total of 3 days to sickness, while the second group lost a total of 40 days to sickness (Stark, 1971).

In a test involving a Swiss bank office, one group of 309 worked in a negative ion-treated environment. A second group of 362 worked in an untreated environment. Over the next several months, for every day lost to respiratory illness (cold, flu, laryngitis, etc) in group one, 16 days were lost to respiratory illness in group two (Soyka, 1991).
