Why negative Ions are so good for the body

In modern life, the air quality is deteriorating with decreasing negative ions and increasing positive ions. This is due to air pollution from various sources i.e. fumes from vehicles, electromagnetic waves/radiation from the broad usage of electronic equipment such as mobile phones, computers etc.

When there are too many positive in the air, we experience physical discomfort and chronic diseases, such as anxiety, insomnia, headaches, allergies, respiratory issues, fatigue, sleep issues, skin conditions, seasonal affective disorder and so on, which are called civilisation diseases.

Therefore, we need to leave the city jungle full of concrete and machines for places where there is nature where there is an abundance of negative ions, to rest and relax so that the negative and positive ions in our bodies can restore to a normal state. This allows the body to get into the right balance to heal itself. If we can reduce positive ions and increase negative ions in our bodies as far as possible, we can become healthier.

How do negative ions enhance your bodies natural defence mechanism?

Most diseases are related to the imbalance of the immune system. Therefore, enhancing immunity has a major concern to modern healthcare. The best way to protect ourselves from diseases should be to focus on how we can improve our own health and not how on how advanced the current medical technologies and research are. The immune system is made up of the innate immunity system and acquired immunity system.

The innate immune system consists of our skin, mucosa and their secretions, phagocytes, protective proteins and natural killer cells (NK cells) etc. Phagocytes eliminate pathogens by ingesting them while NK cells can kill infected or mutated (such as cancer cells) cells. The acquired immune system contains T lymphocytes and B lymphocytes. They are the cells that recognise attack and destroy invading bacteria and viruses.

Negative ions can improve our immune system by strengthening our immunity cells, making them more energetic, healthy and therefore enhance their ability to destroy the pathogens. Negative ions can also speed up the production of antibodies by the lymphocytes, increasing the number of antibodies in our bodies. With a strong immune system, we will be less prone to falling sick and even if we do, we will be better equipped to destroy pathogens and improve recovery time.

How do negative ions activate the cells?

Every cell consists of 3 parts i.e. the cell membrane, plasma and nucleus. The cell membrane has small openings for cellular nutrients to enter, a specific channel for protein and some antennae for sensory and cell defence. Cell plasma serves as the factory of nutrients for the cell and the nucleus serves as the control station of the cell, responsible for the cell’s replication, inheritance and regeneration. There are many kinds of cells in our bodies and all of them have their own specific function.

The cells in charge of our body’s defence are called immune cells and they consist of lymph cells and white blood cells. Since the immune cells are in charge of protecting the human body, why does diseases still happen? In some conditions, it may be because of a large number of pathogens (bacteria or virus).

Combined with a weak physique (especially in a person with an acidic constitution or hereditary deficit), cells may be easily attacked and injured. Therefore, it is of utmost importance that we keep our cells healthy. Negative ions activate and enhance cell activities by;

1. Increasing the permeability of the cell membrane. This facilitates waste removal and nutrient absorption, keeping cells healthy.

2. Facilitating substance exchange across cell membrane through re-activating the Na-K
pump to restore nutrient and waste exchange in an acidic constitution.

3. Promoting oxygen absorption by the cells through the increased oxygen carrying capacity of the red blood cells.

Negative ions of oxygen are really the vitamin of the air!

Negative ions health



You cannot change the air outside, but you can do something about the air you breathe around you.
Air cleaners are a good consideration for the home, and there are many types that have various filters to clean the air in the house. However, they are limited in their capabilities.

Around 1890 researchers Elster & Geitel from Germany, and Thomson in England, each independently discovered the existence of Air Ions. Immediately afterward biologists and physicians began investigations on whether the existence of ions might influence physiological processes. In the years since, hundreds of papers published globally have detailed various findings, of which the most interesting is that not all Ions are necessarily ‘Good’ Ions.

Air is made up of 78% nitrogen, 20% oxygen, 1% argon, 1-3% carbon dioxide, with the remaining 2-3% being rare gases. These elements combine with other suspended matter found in the air to form molecules. An ion is formed if any of the molecular clusters acquire an electrical charge by gaining or losing an electron. If a cluster loses an electron it is called a ‘Positive Ion.’ If a cluster gains an electron it is called a ‘Negative Ion.’

By the 1960s Albert Krueger from the United States (now a friend of Mr. Joshua Shaw) was the first to categorically prove the effects of both these ions on therapeutic responses through his studies on mice. He conducted extensive animal studies and found that high concentration of Positive Ions (in negative ion-depleted air) increased the cumulative death rate in mice infected with the influenza virus. Whereas higher concentrations of Negative Ions (positive ion-depleted air) reduced the death rate to nil. In high concentrations of Negative Ions, the mice were able to repel the virus and repair the damage it did to their bodies – in other words, make a full recovery.

Countries such as Russia, Israel, U.K., Finland and the U.S. also became very active in researching the adverse effects of positive ions and beneficial effects of negative ions. Today, it is commonly accepted that an air mixture too rich in positive ions, as in polluted air, may cause low mood, fatigue, headaches, irritability, exacerbation of respiratory ailments, and a reduced ability to recover from illness.  WIn contrast, an air mixture rich in small negative ions will cause a lessening or elimination of such symptoms.

Elanra has the unique ability to negatively charge the ambient air by generating ions small enough to be ingestible.  Within the range of an Elanra device, you can be assured that you are breathing the best quality small negative ions of Oxygen.

Negative ion facts and research

In an effort to reduce air pollution-related health problems within buildings, various air purifying methods have been developed including air filtration and purification by air ionization and other methods.

Domestic ion generators have been developed to eliminate airborne pollutants, allergens and infectious agents from immediate breathing spaces by charging and precipitating airborne particulate matter and creating localized zones of improved air quality.

Negative Ion generating devices have been shown to be the most effective against air pollutants of sizes, 10 microns (PM10) down to the dangerous 2.5 microns (PM2.5) such as dust, cigarette smoke, pet dander, pollen, mold spores, viruses, and bacteria.

It is known that positive ions build up in the atmosphere prior to a storm front, whereas negative ions accumulate following a storm. Some strong moving water produces negative ions and it is common for people to feel invigorated after visiting the sea, waterfalls or rainforests.

Although many ion generators can be effective in clearing the air, few have the capacity for a higher ion ‘output, flow rate and hence speed’ effective over a reasonable distance to the user. These specifications are necessary to provide an additional range of therapeutic effects directly to the user.

“The Elanra produces small biologically active negatively charged ions of Oxygen, pulsed at various selective frequencies that are emitted into the ambient air to be inhaled and ingested via the lungs and into the bloodstream of the patient to produce a positive therapeutic or biological effect.” TGA Registration Certificate for the Elanra range.

Comparison between Elanra Ionisers and other Ionisers

Elanra ionisers have been specifically designed to produce consistently high volumes of small negatively charged ions of oxygen with no harmful ozone production. In addition to the superior output, the user can select from a range of pulsed frequencies targeting different health conditions in combination with the ability to vary the output to suit the health condition sought.

Elanra has global patents on this unique functionality. Up to 144 different health programs are available to suit the individual’s therapeutic requirements. Consequently, with its advanced technology, Elanra has become a leader in the use of air ionisation to provide direct therapeutic benefits beyond mere air cleaning and disinfection.

Literature Review

The scientific study of biological effects of small air ions and negative ion generators has been associated with such fields as meteorology, environment, air quality, pollution, bacterial control, human performance, and health. Consequently, over the last century, a huge body of literature, journal articles, books and conference proceedings have accumulated. It appears Russia, Israel, and Europe are the early and current adopters of this technology, with its application in many hospitals.

Enhanced Vitality and Performance

Air quality and the effect of ionised air on performance was studied extensively in Russia. Clinical and polyclinical institutions provide medical grade doses of negative ions for increased physical work capacity and improving general tone of healthy people. Minkh (1961) reported on the effect of ionised air on work capacity and vitamin metabolism of groups of athletes at an Institute of Physical Culture and Training. The studies showed that daily sessions of negative polarity gave rise to a “considerable increase in general tone, cheerfulness, energy, good sleep, and appetite.” Large improvements were found in endurance to both static and dynamic work as well as ability to keep equilibrium in positions of varying difficulty. Most notable was that negative ionised air had a favourable normalising effect on the metabolism of vitamins B and C regulating their increased consumption in sports exercise.

Much research has focused on ‘sick building syndrome’ where ambient air quality and other factors give rise to adverse effects on occupants. Hawkins in 1981 investigated Air ionisation and office health and incidence of a headache, nausea, and dizziness. He concluded that the use of negative ion generators appears to bring about a significant reduction in the number of complaints of a headache, nausea, and dizziness.1

Richardson in the UK carried out a two-stage intervention study to establish the degree of which indoor air quality could be improved by reducing the number of airborne fine particles. Results showed that an electrostatic air cleaning system could significantly improve an office environment.2

An article on New Scientist.com news service in 2003, reported that repeated airborne infections of the bacteria actinobacteria in an intensive care ward at St James Hospital in Leeds had been eliminated by the installation of a negative air ioniser.3

There is sufficient evidence to conclude that the Elanra Medical Ioniser being significantly more powerful than the ionizers used, will produce improved oxygen uptake, vitality and stronger performance in a work and sporting environment.

In 1962, a group in Philadelphia studied the effects of intermittent exposure to negatively ionised air on surgical patients on the first and second postoperative day.  The sedating and pain relieving quality of this method, observed previously in a large series of burned persons and in repeated electroencephalographic tests was confirmed. No adverse symptoms were recorded.4

Terman and Terman reported the conduct of a controlled trial of high density and low-density negative ions in seasonal affective disorder (SAD) on 25 subjects. They concluded that exposure to a high-density negative ion generator appears to be specifically antidepressant in SAD patients. The 15% response to the low-density ionisation they regarded as a placebo response. The method may be useful as an alternative or supplement to light therapy and medications.5

You may not be able to change the air quality outside, but you can improve the ambient air you are breathing inside your home. For best results consider the Elanra™ to help maintain your health.

Pollutants and pathogens impact your body, and the vital blood that carries oxygen to all your organs, muscles and cells., These create an imbalance in the body that can result in ailments being ignited or exacerbated. Elanra Oxygen corrects this imbalance, enabling your body to repair itself from the ravages of the day, and all while you sleep.

The type of environment that provides healthy air naturally and for free is found around waterfalls, in forests or where ocean waves break over rocks with great force. If only we could spend every moment of every day in these areas, we would not need Elanra! So why are these environments so fresh and clean, and why are we able to ‘breathe deeper’ when we are there, rather than at home? The reason is that the air in these environments is abundant with trillions of a special type of oxygen molecule known as a ‘Small Negative Ion of Oxygen’.

We call it a ‘Species of Oxygen’ and ‘Special Oxygen’, because through years of research at Elanra Medical, we have developed a unique and special understanding of how this subatomic ion lives, moves and works to influence our bodies. This species of Oxygen is part of our team, our cultural DNA, our family, holding a relationship with every worker in our company, as we all embrace incredible pride to represent a product that is so unique and special.

Recreating this ‘Special Oxygen’ that is readily available in the natural environment is an extremely difficult process, and it is the purpose of Elanra to do just that, all while, maintaining a consistent quality output, and ensuring the Special Oxygen can reach the depths of the lungs and be ingested into the body.

The extremely sensitive and involved process to produce these ions requires the world’s most advanced electronic components and precise manufacturing technology. Naturally, these processes are patent-protected as Elanra Medical’s intellectual property.

From the initial inspiration of the inventor, our own Mr. Joshua Shaw, followed by subsequent years of research and development, we have been able to enhance our advanced technology to deliver this unique bio-solution to humanity.

The Elanra rebalances the body’s systems and restores the physical body by assisting in its recovery from damage inflicted throughout the day, all whilst you are sleeping. It’s the easiest step you can take toward attaining good health and wellbeing.

Elanra safely and reliably produces small negative ions of Oxygen, without generating harmful ozone, and this is one important reason that it is able to be registered as a medical device. This standard is unique to Elanra and to Australia.

The Special Small Negative Ion is the vital ingredient of the Oxygen family that our body requires. Mr. Shaw has given humanity the ability to bring the life-giving force of the waterfall into the home, bedroom, car, and hospital – in fact anywhere we may be in our modern world.

We live in an ocean of air and each of us is inexorably required to breathe in at least ten thousand litres of air every twenty four hours just to maintain life in our bodies. Since we are utterly dependent upon the physical and chemical properties of this air, it isn’t surprising that we are now deeply immersed in exploring all atmospheric parameters. Characteristically, most of our efforts are devoted to the detection and control of those toxic particulates and gases contributed to the ambient air by industry and by the multitude of anthropocentric activities which require the combustion of fuel. Their threat to life is pressing and it is obvious that measures for their abatement must be developed in the immediate future. Other, more subtle atmospheric changes are in progress which, because they are less conspicuous, tend to be put aside for future consideration. Among these one would have to list those phenomena involving small air ions.

Air Ions and Health

In places where mountains are situated to the south, the south winds that blow are parching and unhealthy; where the mountains are situated in the north, their northern winds occasion disorders and sickness…The winds which must pass over mountains to reach cities do not only dry, but also disturb the air which we breathe and the bodies of men, so as to engender diseases. Hippocrates, Regimen II, Chapters 37-38 click here.

The reactions between water, land and air during the long slow physical evolution of our planet have greatly affected the course of biological evolution. To a very considerable extent, this interplay is responsible for the emergence of man – a singular product of evolution – and man, in an extremely brief span of time, through his genius for blindly manipulating natural resources, has attained the unique capacity to alter his total environment. While we have begun to express serious concern for the grim consequences of our role as spoilers in disturbing ecological balances in general, our interest is most avidly focused upon those facets of man-engendered pollution which pose the most immediate and direct danger to us.

We live in an ocean of air and each of us is inexorably required to breathe in at least ten thousand litres of air every twenty four hours just to maintain life in our bodies. Since we are utterly dependent upon the physical and chemical properties of this air, it isn’t surprising that we are now deeply immersed in exploring all atmospheric parameters. Characteristically, most of our efforts are devoted to the detection and control of those toxic particulates and gases contributed to the ambient air by industry and by the multitude of anthropocentric activities which require the combustion of fuel. Their threat to life is pressing and it is obvious that measures for their abatement must be developed in the immediate future. Other, more subtle atmospheric changes are in progress which, because they are less conspicuous, tend to be put aside for future consideration. Among these one would have to list those phenomena involving small air ions.

Very shortly after the existence of atmospheric electricity was demonstrated by Franklin [1] and by d’Ailbard [2] in the mid 1700’s, several natural philosophers ascribed to it a variety of biological effects. For example, Father Giambattista Beccaria [3] in 1775 reported that “it appears manifest that nature makes extensive use of the atmospheric electricity for promoting vegetation” In this he was supported by Abbe Nollet [4] and Abbe Bertholon [5]. Abbe Bertholon [6] in addition concluded that the course of various diseases of man was influenced by atmospheric electricity. I 1899, Elster and Geitel [7] and J J Thompson [8] independently proved that atmospheric electricity depends upon the existence of gaseous ions in the air. It then became possible to develop generators for producing air ions and equipment for determining their numbers in the air. Using these technical aids, a vast amount of experimentation was undertaken to define the physical and biological properties of air ions. There are ions in the air around us all the time, but changes in their concentration or in the ratio of positively to negatively charged molecules can have marked biological effects on plants and animals. Indeed, ion depletion and charge imbalance may play a significant role in a wide range of human ailments including respiratory infection in office workers and the malaise caused by weather conditions such as the khamsin winds of the near East. Further, artificially generated air ions may prove valuable as a therapeutic modality in the treatment of burns, reparatory disorders, stomach ulcers nd nervous disorders.

Air ion formation begins when enough energy acts on a gaseous molecule to eject an electron. Most of this energy comes from radioactive substances in Earth’s crust and some from the shearing forces of water droplets in waterfalls (Lenard effect) or the friction which develops when great volumes of air move rapidly over a land mass (for example, the foehn, sharav and Santa Anna winds) or from cosmic rays. The displaced electron attaches itself to an adjacent molecule which becomes a negative ion, the original molecule then becoming a positive ions. Molecular collisions transfer the charge, so that positive charges come to reside on molecules with the lowest ionisation potential,while electrons are attracted to the species of greatest stability. Next, small numbers of molecules of water vapour, hydrogen and oxygen cluster about the ions to form small air ions. In normal pollutant free air over land, there are 1500 to 4000 ions/cm3. But negative ions are more mobile and Earth’s surface has a negative charge, so negative ions are repelled from the Earth’s surface. Thus the normal ratio of positive to negative ions is 1.2 to 1.

Certain properties of small air ions are pertinent to this discussion. They readily unite with condensation nuclei and with most classes of air pollutants to form large or Langevin ions. In both cases the biological activity of the small air ions is lost. This is true also of the combination that occurs between small air ions of opposite charge. Further, ions like charge (unipolar ions) repel one another and tend to flow to enclosing surfaces where their ionic nature dissipates. Since they are small and carry a charge, they are deflected by electrical fields. All of these characteristics make it difficult to maintain high concentrations of small air ions and means that air ion densities are significantly altered by the indoor living and air pollution characteristic of urban life.

While the nature of air ions was under investigation by the physicists, vigorous attempts were being made by the life scientists to determine their biological effects. Although the amount of work accomplished by the biologists is a tribute to their industry, it must be admitted that many of the results reported in the literature is not convincing. Several factors in the area of experimental design served to cloak the whole field in an aura of ambiguity. Often experiments were performed with corona discharges as ion sources, neglecting the ozone and oxides of nitrogen sometimes produced along with the ions. Ion densities, temperature and relative humidity were not monitored. Experimental subjects were not grounded; their external surfaces developed high electrostatic charges and in consequence, repelled ions. As a rule, the air was not purified and combination of ions with air pollutants led to widely fluctuating ion densities. Clinicians assessing the value of air ions as a therapeutic modality frequently committed all or some of the errors listed above and in addition, neglected to utilise the double blind cross over technique for ion administration. In view of these omissions, it is not surprising that convincing proof of the role played by air ions as physiological mediators or as therapeutic agents has been slow to emerge.

In addition to these elements of uncertainty in experimental procedures, the evaluation of air ions as biologically active agents has been hampered by the widely cultivated belief that the idea is theoretically absurd. There seems to be something about the term “ion” that provokes incredulity – consider the state of Svante Arrhenius, who first applied it in 1884 to describe atoms and molecules in aqueous solution bearing a positive or negative charge which enabled them to migrate in an electrical field. His doctoral committee thought this idea so bizarre that they accepted his work with the greatest reluctance and granted his degree with the lowest possible grade. The major obstacle to acceptance of this magnificent concept was the requirement that fundamental differences in the properties of charged molecules (ions) and uncharged molecules be acknowledged. In the case of air ions there is no disagreement about the disparate physical nature of air ions and non ionised gaseous molecules, but there is considerable reluctance to grant that this diversity is of biological significance.

At any rate, the essence of the argument against biologically active air ions is this: The maximal ion density one can attain in a closed atmosphere is approximately 1 x 106 ions/cm3, of air. Air contains 2.7 x 1019 non ionised molecules/cm3, so that the ratio of small ions to non ionised molecules is 1:27 trillion. For the reasons already mentioned above, ions have a very brief life span and under the conditions ordinarily prevailing, attainable ion densities usually are considerable less than 1 x 106 ions/cm3, making the final dilution in non ionised air greater by one or two orders of magnitude. From this unquestioned fact, the dubious conclusion has been drawn that the very sparseness of air ions places them beyond the range of biological effectiveness. The merit of this inference is more specious than real, since many biological systems respond to extremely minute chemical and physical stimuli. Two examples suffice to bear out this contention: first, the human eye can detect a flash of light when a single active quantum reaches the retina [9]; and second, the male silkworm reacts to as few as 2600 molecules of the female’s sex attractant pheromone in air containing a concentration of <200 a="" activities="" administration="" advertising="" air="" alike="" and="" any="" application.="" brought="" campaigns="" cm3="" commercial="" conclude="" development="" directly="" diseases.="" div="" drug="" during="" efficacy="" episode="" even="" exploitation="" extolling="" factor="" federal="" field="" for="" fraud.="" further="" generators="" halt="" has="" high-powered="" in="" ion="" ionisation.="" is="" laymen="" led="" medical="" mid-1950="" mis-representation="" molecules="" of="" one="" or="" outright="" permeated="" prohibited="" public="" range="" retarded="" s="" sale="" scientists="" since="" sold="" subject="" that="" the="" their="" then="" these="" this="" through="" to="" treating="" unfortunate="" were="" whole="" wide="" with="">

It is evident then that progress in the field of research devoted to the detection of air ion effects on living forms has been retarded by the very real difficulties attending the performance of meaningful experiments, by an unhappy example of commercial exploitation and by categorical rejection of the whole idea as a matter of principle on the part of many component scientists. The technical obstacles are the major reason that we now are faced with enormous accumulation of data of very uneven quality. The matter of rejection is not so vital, although it is disconcerting at times to find that some of our peers classify the subject with the occult arts.

THE BIOLOGICAL EFFECTS OF AIR IONS

The experimental observations taken as a whole serve to establish the fact that air ions are physiologically active and can produce functional alterations varying from barely discernible to substantial. Further, air ions, are capable of evoking a wide range of response in bacteria, protoza, higher plants, insects, animals and man. Sometimes both positive and negative ions induce essentially the same biological reaction, in other cases they elicit the opposite effects. A few selected examples will be presented to illustrate the range of biological effects of small air ions and the reader is referred to more detailed reviews of the experimental evidence [11, 12, 13].

A brief review of the effects of air ions on micro-organisms reveals that both negative and positive ions (1) inhibit the growth of bacteria and fungi on solid media, (2) exert a lethal effect on vegetative forms of bacteria suspended in small droplets of water, and (3), reduce the viable amount of bacterial aerosols [12].

With mammalian cells in tissue culture, Worden found that Girardi’s human heart cells exposed for fourteen days to unipolar ionised atmospheres and then transplanted into non-ionised atmospheres for an additional fourteen days showed adversely affected growth characteristics and rate of proliferation with positively ionised air; growth was normal with negatively ionised air. Using fibro blasts he obtained statistically significant evidence that negative ions increase and positive ions decrease the rate of proliferation. Furthermore, when the fibro blasts were removed to a non-ionised atmosphere, the cells previously exposed to negative ions continued to divide at an increased rate, while the cells treated with positive ions recovered slowly and eventually attained the normal rate of growth [14].

Over the past nineteen years, the Air Ion Laboratory of the University of California has conducted experiments to detect ion-induced physiological changes in plants and small animals. The subjects were maintained in a controlled micro-environment supplied with pollutant-free air, the sole variable being concentration of air ions in the ambient atmosphere. Soft ß (beta) emission from tritium absorbed on zirconium served to ionise the air without evolving toxic by-products; selection of positive or negative ions was accomplished by applying a corresponding charge to the generator electrode.

Plants appear to benefit from increases in both positive and negative ionisation, and we have shown that such ionisation markedly increases the rate of growth of higher plants such as barley, oats and lettuce. With seedlings grown in chemically defined media, we found that unipolar (one charge only) ionised atmospheres containing approximately 10,000 positive or negative charged ions/cm3 increased the rate of growth by as much as 50%(as measured by integral elongation or weight) without altering the protein, sugar, or chlorophyll content of the plant. In marked contrast to growth stimulation elicited by air ions, their removal from the atmosphere resulted in a lower rate of growth, reduced turgor (pressure in plant cells) and the development of soft, fleshy leaves. Chlorophyll production was not affected[15]. Several clues to the biochemical mechanism were uncovered. Positive and negative ions expedite both the uptake of iron and its utilisation of the production of ion-containing enzymes. The ions stimulate the metabolism of the high-energy compound adenosine triphosphate (ATP) in the chloroplast’s and augment both nucleic acid metabolism and oxygen uptake. All of these phenomena are consistent with the observed ion-induced increase in growth rate.

Similar results were obtained when silkworm eggs and emergent larvae were exposed to ions of either charge. Hatching began earlier, larval growth accelerated and there was increased synthesis of three enzymes (catalase, peroxidase and cytochrome C Oxidase). Spinning began earlier and cocoons were heavier [16].

Much of the work we have done with animals has been on air ion effects in the respiratory tract and we found that air ions influence survival in respiratory diseases. High concentrations of positive ions substantially increased the death rate of mice infected with measured doses of a fungus (Coccidiodes immitis), a bacterium (Klebsiells pneumoniae) or a strain of influenza virus, all administered intranasally. Ion depleted air (comparable to ion concentrations found in urban environments) also increased the death rate in mouse influenza while a high concentration of negative ions decreased the death rate [17]. In other experiments where the influenza virus was introduced as a fine aerosol, this by-passing the protective mechanisms of the upper respiratory tract, changing ion concentrations had no influence on the death rate. This and other observations suggest that the site of action of air ions is the mucosa of the upper respiratory tract [18].

An Ecological View of Health

MECHANISM OF AIR ION ACTION

With regard to the mechanism underlying the response of animals to air ions, we have worked for several years on the changes in blood levels of serotonin (5-hydroxy tryptamine or 5-Ht), a powerful neurohormone capable of producing profound neurovascular, endocrine and metabolic effects throughout the body. In the hypothalamus 5-Ht participates in various processes such as sleep, the transmission of nerve impulses and in our evaluation, of mood. We found a readily reproducible and significant change in blood 5-Ht levels in mice exposed to air ion densities of 4-5×105 positive or negative ions/cm3. Positive ions raised blood levels of 5-Ht, while negative ions had the opposite effect. Additionally, we found that the brain content of free 5-Ht was responsive to the concentration of ions in the air. Because of the chief metabolic route for removing Serotonin (5-Ht) depends upon the enzyme monamine oxidase, we hypothesised that small negative ions stimulate, while small positive ions block the action of monamine oxidase, thus producing respectively a drop or rise in the concentration of free 5-Ht in certain tissues and eliciting a corresponding physiological response [19].

This general mechanism of air ion action has been confirmed by other investigators. Grant Gilbert at Pacific Lutheran University demonstrated that continuous treatment with negative ions produced statistically significant reductions in emotionality and brain Serotonin levels in rats [20]. Jean-Michel Olivereau of the Psychophysiology Laboratory at the University of Paris conducted extensive experiments on the endocrine systems and the nervous mechanisms of rats treated for various periods of time with air ions [21, 22]. Employing elegant biochemical and histochemical techniques, he surveyed air ion action on the hypothalamus, the hypophysis, the adrenals, the thyroid, brain metabolism, behaviour, eating, spontaneous activity, psychomotor performance and adaptation to stress. He concluded that air ion-induced alterations in blood levels of 5-Ht account for very significant physiological changes in the endocrine glands and central nervous systems, these, in turn, substantially alter basic physiological processes. A significant facet to Olivereau’s research is his observation that negative ions exert a measurable anxiety lessening effect on mice and rats exposed to stressful situations, a phenomenon noted by several other workers [23]. This response parallels that which follows administration to animals or man of the drug reserpine. Both reserpine and negative ions reduce the amount of Serotonin in the mid-brain and this apparently accounts for the tranquillising action.

Direct and indirect evidence supporting the theory that 5-Ht is an important mediator of air ion action on animals and humans is found in the reports of several investigators [24-25] and is reviewed elsewhere [26,27]. However, there is no reason to suppose that 5-Ht is the sole agent responsible for air-ion induced alteration of physiological function.

Such tentative biochemical probings are really no more than the first step in elucidating the arcane mechanisms when air ions make contact with the tissues of the test organism. Our ignorance extends from the interface between the atmosphere and the cell wall to include the cellular organelles, their component enzyme systems and almost all the tissues and organs of living forms.

When we turn to the matter of air ion dosage necessary to elicit biological responses, the situation is somewhat better. Dosage constitutes a very practical element, for if extremely high ion densities are demanded, there is little likelihood of air ions playing a significant role in nature and the whole topic becomes academic, or at best, is limited to therapeutic applications. If on the other hand, biological effects are associated with such displacements of ion densities or charge ratios as are known to occur in Earth’s atmosphere, or even with relatively small shifts in ion concentration that can be affected by ion depletion or artificial ionisation in ordinary living and working quarters, the subject acquires great interest and importance.

An outstanding example of dependence of physiological response upon dosage has been reported by Bachman and his co-workers [24]. In studying the influence of air ions on the spontaneous activity of rats they noticed a curious zonal response with activity levels falling, rising and peaking then falling again as negative ion concentrations were increased.

Several studies, however, have demonstrated marked biological effects with lower dosage approximating natural conditions (1.5×103 to 4×103 small ions/cm3). In the experiments of Knoll and his collaborators on the effects of ions on simple visual reaction time in humans, ion concentrations of only 2×103 ion cm3 produced a remarkable decrease in reaction time [28]. Delaneau and his colleagues found that relatively small ion dosages, for example, 5×103 to 15×103 ions/cm3 of air effectively influenced the development of gastric ulcers in starving rats [29]. Silverman and Kornblueh were able to detect changes in alpha frequencies of the EEG in humans exposed to only 1.8×103 positive or negative ions/cm3 for thirty minutes [30]. Also, a sudden increase in negative ions or a precipitate drop in positive ions within the atmospheric range of 1×103 to 2×103 ions cm/3 was reported to increase moulting in aphids [31].

In our studies mentioned above on the effect of air ions on the course of mouse influenza produced by intranasal challenge, we found that ion dosage influenced the cumulative mortality rate. Unipolar low densities of positive or negative ions (comparable to indoor and urban environments) increased the rate of death, mid-range concentrations of ions of either charge had no effect, while a reduction in mortality rates occurred when the animals were exposed to high concentrations of negative or to low concentrations of mixed ions with mixed ions with negative ions predominating [17].

Natural Ion Environment

We have already presented evidence that air ion concentrations comparable to those found in nature can modify physiological processes in a variety of living forms under laboratory conditions. Now it seems appropriate to ask, Do air ion-linked phenomena occur in humans outside the laboratory? This question can be answered affirmatively with some assurance in light of recent investigations of large scale weather-related changes in air ion concentrations and charge ratios coupled with concurrent clinical studies.

To begin with, a great deal of work has been done in France, Italy, Germany and the USSR on the ionic environment of spas, particularly those situated near waterfalls. The consensus seems to be that the air in many such locales for whatever reason, contains a high concentration of small air ions with a ratio of negative to positive ions being considerably greater than normal – The Lenard effect. Bio climatologists are inclined to attribute to this fact some of the vis mediatrix of these resorts. This is an attractive hypothesis, but one that is difficult to prove, since many curative modalities are brought to bear on patients simultaneously.

Turning to the adverse effects associated with certain ion environments, there have been long traditions in the folklore of nearly every country that link certain changes in weather with changes in health and behaviour. One such tradition has to do with the winds of ill repute, for example, the Foehn (Southern Europe), Sirocco (Italy), Santa Ana (United States), Khasmin (Near East), and Mistral (France). Wherever they prevail, their victims attribute to them the ability to induce respiratory distress of various sorts, nervousness, headache and a multitude of other ills. So malign is their influence that when they blow, judges deal leniently with crimes of passion, surgeons postpone elective surgery and teachers expect more than the usual fractiousness from their students.

Since the turn of the century, several scientists and physicians have hypothesised that the immediate cause of such malaise is the upset in electrical balance of the atmosphere that precedes or accompanies the winds. This relationship between air ions and disease, tenuous at first, is finding support in the meteorological observations of investigators such as Robinson and Dirnfield who studied the Sharav, a weather complex afflicting the Near East and characterised by persistent wind, a rapid rise in temperature and a fall in relative humidity. Robinson and Dirnfield measured solar radiation, temperature and relative humidity, wind velocity and direction and the electrical state of the atmosphere before, during and after the Sharav. They found that 12 – 36 hours before the characteristic changes in wind, temperature and humidity, the total number of ions increased (from 1500 ions/cm3 to 2600 ions/cm3) and the ratio of positive to negative ions jumped from the normal 1.2 to 1.33. This early shift in ion density and ratio coincided with the onset of nervous and physical symptoms in weather sensitive people and was considered the only meteorological change that could be responsible for the discomfort associated with the Sharav [32].

This conclusion is supported by the extensive studies of Professor Felix Sulman and his colleagues in Jerusalem. They designate as the “Serotonin Hyper function Syndrome” the cluster of signs and symptoms that afflict a considerable segment of the population a day or two before the onset of a hot dry wind characteristic of the Sharav. Individuals in this category suffer from insomnia, irritability, tension, migraine, amblyopia, oedema, palpitations, precordial pain, respiratory distress, hot flashes, tremor, chills, diarrhoea, polyuria, vertigo etc. These patients display an increased output of Serotonin in the urine and they experienced relief when treated with negative ions or with Serotonin blocking drugs [33,34]. There exists then, a scientific basis for accepting the tradition that the winds of ill repute can produce malaise in humans, that air ion imbalance is the direct meteorological incitant and that the proximate cause of the irritation syndrome is the positive air-ion-induced hyper secretion of Serotonin. Supporting laboratory evidence for the adverse effect in humans of air ion imbalances comes from a well controlled double blind experiment by Winsor and Beckett in which volunteer subjects developed a dry throat, husky voice, headache, itch or obstructed nose and a reduction in maximum breathing capacity when exposed to nasal inhalation of positive ions in concentration of 3.2×104 ions/cm3 [35].

AIR IONS AND THE HUMAN URBAN ENVIRONMENT

In modern urban life, man often faces ion conditions far different from natural ion balances, with a significant depletion of small air ions and a markedly increased ratio of positive to negative ions commonly encountered. A fourteen day study in 1971 by B. Maczynski and others showed that in an office containing four people the small air ion concentration dropped as the day went on, falling on the average to only 34 positive ions and 20 negative ions/cm3 [36]. Central heating and air conditioning, smoking, the usual household activities of dusting and cooking all combine to lower levels of small ions in indoor environments. Further, the static electricity generated by the widespread use of synthetic fibres in clothing and room furnishing as well as stray electric fields add a different dimension to the indoor climate which is not conducive to the preservation of small air ions [37].

The effects of air pollution on air ions in the ambient atmosphere are also marked. As stated earlier, the small physiologically active air ions readily combine with gaseous and particulate pollutants to form large (Langevin) ions that are considered physiologically inert. A test in a light industrial area of San Francisco by J C Beckett in 1959 showed a small ion count of less than 80 ions/cm3 as compared to levels of 1500-4000 small ions/cm3 found in fresh unpolluted air [38]. The fundamental reaction is disarmingly simple: man- atmospheric pollutants; atmospheric pollutants + small air ions – air ion depletion.

That this progression has attained significant magnitude is evidenced by the fact that small air ion levels far at sea – normally very constant – are becoming appreciably lower with time, as air pollutants drift out from land. Thus wile very few of our activities add small air ions to the air, much of what we do cumulates in ion loss. The question then amounts to this: Will the smogs, hazes and invisible pollutants we generate with a lavish hand so reduce the small ion content of the atmosphere that plants, animals and man must suffer the harmful consequences?

Although the early results of ion depletion very likely will be unimpressive compared to the immediate and dramatic action of known toxic components of polluted air, this alone should furnish little solace. We have every reason to be aware from past experience that adverse effects may follow continued exposure to a small amount of a minor irritant (for example, organic solvents) or the long term deprivation of an essential metabolic requirement (for example, trace elements or vitamins). People travelling to work in polluted air, spending eight hours a day in offices or factories and living their leisure hours in urban dwellings inescapably breathe ion depleted air for substantial proportions of their lives. There is increasing evidence that this ion depletion leads to discomfort, enervation and lassitude and loss of physical and mental efficiency. This syndrome appears to develop quite apart from the direct toxic effects of the usual atmospheric pollutants.

Physicians and environmental engineers have long suspected that the inimical effects of “dead air” in crowded rooms are due to ion depletion. In 1939, three Japanese Scientists, S Kimura, M Ashiba and L Matushima showed that if temperature, humidity and carbon dioxide levels were all kept within ranges considered suitable for human comfort, but the ion level was reduced, individuals suffered from such as perspiration and depression. Further, these symptoms were promptly relieved when normal ion densities were restored by the use of ion generators [39]. Recently, a team of Soviet scientists tested the effects of varying ion conditions on humans employing an impressive battery of tests to measure cardiovascular functioning, reaction time and blood chemistry. They concluded that any enclosed compartments with “conditioned” air such as a space capsule, are likely to be depleted of ions and have a considerable excess of positive ions and that prolonged stays in such an ion environment is detrimental. The Soviet scientists recommended that ionisation in such environments be increased to a more normal 2000 ions/cm3 and that the addition of negative ions be alternated with positive or bipolar ionisation [40]. The effect of various ion concentrations and charge ratios on human performance, reaction time, vigilance and psychomotor tasks is suggestive but inconclusive and has been reviewed elsewhere [41].

ARTIFICIAL ION GENERATION: CLINICAL APPLICATIONS

So much for the potential role of an air ion-depleted environment in man’s future. There remains the more promising consideration of the environmental and medical applications of artificially generated air ions. At present, there exists several means of artificially producing air ions, including corona discharge and tritium generators. These ion generators make it possible to re-establish natural and optimal microclimatic conditions in living and working quarters. Eventually air ion standards for comfort and health may be established, just as we now have set limits for temperature, relative humidity, carbon dioxide levels, etc. It may also be possible to make available, highly beneficial ion-rich micro environments that could serve various hygienic and therapeutic functions. However, the development and use of this technology must go hand in hand with efforts to reduce air pollution from industry, automobiles and tobacco smoke, which effectively interfere with attempts to create a balanced ionised atmosphere.

If the results of our experiments with respiratory disease in mice can be extrapolated to man, we might expect that the ion depleted air of our offices and factories would lower resistance to influenza and perhaps other infections. Conversely, inhaling a mixture of air with, say, 4000 ions/cm3 and with negative ions predominating, should increase resistance. A recent study in a Swiss bank indicated that this is so. In the test, 309 volunteers worked for thirty weeks in an area where the air was treated to develop a high ratio of negative to positive ions, while 362 controls, worked in untreated air. During the test, the ratio of days lost because of respiratory illness in the two groups was an incredible 1 to 16 [42].

Finally, one can look at some medical applications of high ion concentrations. Kornbleuh and his colleagues have used negative ion therapy successfully for burn patients. Hospitalised patients were treated for 1 to 1.5 hours a day and out patients for twenty five to thirty minutes, to negative ion concentrations as high as 10,000 ions/cm3. Pain, restlessness and incidence of infection were reduced and healing promoted [43]. This application may be related to Serotonin hypothesis of air ion action. Burn patients present increased levels of Serotonin (5-hydroxtryptamine) in damaged tissues and in the blood and Serotonin is known to be associated with pain under some circumstances. We have shown in laboratory animals that inhalation of negative ions increases the conversion of Serotonin to 5-hydroxyindolacetic acid (a physiologically inactive metabolite) and this reaction may be involved in the relief of pain reported by burn patients treated with a high concentration of negative ions.

Another instance of laboratory observations coinciding with clinical usage is to be found in our work at the university of California and that of Palti, De Nour, and Abrahamov at Hadassah Medical School in Jerusalem. Smith and Krueger noted that the inhalation of positively ionised air by small animals contracted the smooth muscle of the tracheo-bronchial tree and decreased the operational efficiency of the mucus escalator, effects that could be duplicated by the intravenous injection of 5-HT; negative ions had the opposite effect[44]. Palti and his colleagues found that exposure to positive ions increased the respiratory rate and degree of bronchospasm in infants with asthmatic (spastic) bronchitis while treatment with negative ions produced an opposite and therapeutic effect. The negative ion therapy terminated the spastic attack after a much shorter period than that required by the conventional mode of treatment and, in addition, no adverse side effects common to the drug therapy, were observed with the negative ionisation. Further, since the subjects in this experiment were infants under the age of one year, the possibility that the observed effects were due to physiological factors was minimised [45].

P C Boulatov, a Soviet investigator, has summarised his experiment work over the past thirty five years involving the treatment of over 3,000 bronchial asthma patients with high concentrations of negative ions. He has reported that after a short period of temporary exacerbation there followed substantial improvements in the general state of the patients, a normalisation of the blood picture, improved respiratory function and a reduction in the frequency and intensity of attacks of bronchial asthma [46]. Kornbleuh, the pioneer American investigator of air ion phenomena and his co-workers obtained temporary relief of acute hay fever symptoms in patients treated with high concentrations of negative air ions. They speculated that the mode of action might be due to some physical and/or chemical effect on microscopic airborne contaminants such as dust, spores, bacteria and pollen or to a direct physiological action on the respiratory tract [47].

More recently, Dr A P Weaner reported on a closely related therapeutic modality: electro aerosols in which minute water droplets act as a vehicle for electric charges. This therapy used extensively in Germany and the USSR has reportedly been applied with success in the treatment of respiratory disorders and various manifestations of autonomic dysfunction such as migraine, nervous tension and depression [48]. Wehner also reviewed the work of K H Schulz who found that negatively charged aerosols seem to stimulate the parasympathetic nervous system and therefore can help to restore autonomic balance in cases of an overstimulated activation. From these observations, Schulz postulated that the effect of the ions would depend on the state of activation of the autonomic nervous system and further, that if the proper charge of ions is administered to a given ion “type” individual a normalisation of autonomic functioning would occur [49].

In line with this theory were the findings of Monaco and Acker, who performed a large number of tests on a group of Psychiatric patients and a group of non-patients. In the psychiatric patients, negative ionisation decreased systolic blood pressure, increased skin resistance and increased pulse finger volume, indicating increased parasympathetic nervous system activity. For the non patients, only a significant decrease in pulse finger volume occurred, indicating slight increase in sympathetic nervous system activity. Thus, it appears that the negative ions had a normalising influence, lowering activation of the psychiatric patients and increasing the activation of the non-patients [50].

Noting the relationship between air ions and neurohormones and following the reports that negative ions produce a sedative effect, R Ucha Udabe, R Kertesz and L Franceschetti at the Catholic University in Buenos Aires tried treating a large number of patients suffering from psychoneurosis and anxiety syndromes. Sessions varied from fifteen minutes to two hours and the number of treatments from ten to twenty. These authors were very impressed with the conspicuous disappearance of simatic complaints and claimed favourable results in 80% of their patients [51]. M Deleanu also claims success in the treatment of gastro duodenal ulcers in animals and man using relatively low dosages of air ions (5000 to 10,000 negative ions/cm3 and 1000 to 2000 positive ions/cm3) [52].

This is only a brief review of some of the developing areas of clinical research, but based on the evidence surveyed in this paper, it appears that air ion investigations constitute a legitimate and promising branch of biological research. As more information is acquired about the mechanisms underlying the reactions between air ions and living systems, we should be able to evaluate more clearly than at present the importance of air ions in nature and assess their potential for clinical and non clinical applications.
