As a regular surfer, I constantly seek to breathe the purest sea air possible. Due to its richness in mineral salts and negative ions, sea air brings many health benefits. The concentration of these elements is increased by swell, waves and winds. To reproduce these effects in the indoor air of my medical office, I decided to test an ionizer device which, in addition to the expected effects on well-being, reduces the presence of microbes, micropollutants and allergens in the ambient air my patients breathe.
An ion is an atom, or a molecule, which has gained or lost one or more electrons. If the atom is neutral, the ion is electrically charged. A negative ion comes from an atom that has gained one or more electrons.
The oxygen molecule O2, which constitutes 20% of the air, is an electrophilic molecule which easily acquires an additional electron (in red on the drawing), to form the ion O2-.
Air is naturally ionized, with a balance between positive and negative ions in natural spaces. There are commonly several hundred to several thousand ions per cm3 in air in their natural state.
In certain natural spaces, one can find large quantities of negative ions: at the foot of the waterfalls, the bursting of the water droplets releases electrons (physical phenomenon called Lenard effect) which ionize oxygen (ion O2- described here -above). Other natural phenomena favor the creation of negative ions, including cosmic radiation and triboelectricity at the tip of needles in thorny trees.
We can thus find large quantities of negative ions in the mountains, by the sea, in the forest, in the sun ...
Negative ions are beneficial for our health (unlike positive ions): they improve our mood, our tone, the quality of our sleep, the concentration, the oxygenation of our tissues ... Negative ions would also make us less vulnerable to stress.
But why do we feel oppressed when a thunderstorm approaches? Why do we feel soothed by the sea? This is where the ions come in, and their influence on our physiology.

While negative ions tend to disappear in polluted environments and more particularly in closed spaces where air is conditioned, positive ions remain present in urban areas and in indoor spaces. Some equipment may even favor the increase of positive ions, such as photocopiers, electronic cards or screens. The first indications of the biological effect of positive air ions on human health came in the form of reports of increased irritability, migraine attacks or thromboses in response to changes in the electrical charge of the atmosphere that accompany incoming weather fronts.
Researchers have found that the electrical charges (positive ionization) generated by each incoming weather front produce a release of serotonin. They then identified three classes of weather sensitivity reactions:
They act mainly by respiratory tracts, and could also intervene by cutaneous ways. They promote exchanges between cells and the penetration of oxygen in the lungs.
Negative ions also have the particularity of ridding the atmosphere of bacteria. The sea air is so pure compared to that of cities, that there are about a hundred times less germs.
In the great Eastern, Chinese and Indian cultures, a vital principle, which one can also call vital breath or vital energy, occupies a central place in the foundations of medicine and the practices of care and personal development. This principle is called Qi in Chinese medicine. Acupuncture and Qigong (traditional gymnastics and the science of breathing) aim to control or improve the circulation of Qi in the body. According to the foundations of Yoga, Prana is the vital energy that circulates in the universe and in all living beings. It is present in the air and the breathing practices of Yoga consist in absorbing this vital energy from the air. However, according to André Van Lysebeth, who is at the origin of
Our body absorbs electricity from the atmosphere, uses it and rejects it through the skin: the more active this metabolism is by the absorption of negative ions and by the evacuation of excess electricity, the more being is "alive" and therefore in good health. Under the effect of negative ions, there is a change in respiratory constants (increase in the alveolar partial pressure of oxygen and decrease in the alveolar partial pressure of carbon dioxide), while under the action of positive ions occurs the opposite phenomenon. In addition, it is the nose which, for yogis, represents the main absorption organ of prana. Air is our main food: we breathe about 13,000 liters of it every day, as much as it is healthy!
In 2013, an Italian team carried out an interesting synthesis of the influence of negative ions on human psychophysiology, concluding that it has a beneficial effect for the treatment of mood disorders (reduction of symptoms) as well as for the improvement of performance. cognitive. «There is individual variability. Some people are more receptive than others to the lack of negative ions. They can have various disorders, for example: fatigue, irritability, lack of concentration, black thoughts, headache, shortness of breath, insomnia », affirms Dr Robert.
British researchers at the Sports and Exercise Center in Liverpool exposed men to negative ions and measured physiological responses, including body temperature, heart rate and respiration, at rest and during exercise. Negative ions significantly improve all physiological states, especially during the rest period. The most important finding is that negative ions are "biologically active and that they really affect the body's circadian rhythm ”.Negative ions allow coronary expansion and increased coronary blood flow, improve heart function by adjusting the heart rate and speed blood flow, quality of sleep, relieve angina and allow normalization of blood pressure.
Some consumer devices using negative ion generation technology have been shown to remove airborne particles, dust, cigarette smoke, pet dandruff, pollen, spores from molds, viruses and bacteria.A powerful ionizer achieves the following results: a 30-minute operation resulted in the removal of 97% of 0.1 micron particles (ultrafine particles) and 95% of 1 micron particles (fine particles). In addition, negative ions reduce the concentration of aerosols in viable bacteria: 95% in 2 hours following laboratory tests. In an experiment conducted in a controlled atmosphere in a stable, ionization reduced the concentration of fine particles (PM10) by 70 to 75%.
The link between air ionization and respiratory diseases can logically be deduced from the influence of ions on the presence of particulate pollutants: the frequency or severity of respiratory disorders must logically be reduced by the reduction of triggers or aggravating factors of diseases respiratory respiratory particles and allergens carried by the air.
Initial epidemiological studies have also shown an influence of ions on asthma, although there is no recent clinical study on this subject. Cossec in France reports the results of the treatment of a group of 30 treated patients long term (a year and a half) and high concentration (of the order of 100,000 ions / cm³ and more at 60 cm distance from the ionizer) having led to a significant reduction in prescriptions for asthma drugs: theophylline derivatives(-43%), corticosteroids (-44%) and antiallergic drugs (-71%).
In addition, negative ions promote the formation of epithelial cells of the nasal mucosa, accelerate the movement of cilia of the bronchial mucosa, improve alveolar ventilation, increase the rate of oxygen saturation in the blood. The clinical results show, after inhalation of negative ions in high doses for 30 minutes, an increase of 20% in the absorption of oxygen, and an increase in carbon dioxide emission of 14.5%. This standardization of functions may help asthma patients.
Ionizers are increasingly being developed in the air purifier category. Air ionization is an effective air purification technology, but one that can generate ozone if it is poorly controlled. Before purchasing an air ionizer, make sure it does not emit ozone! This gas is harmful to health and will therefore cancel out all the benefits of negative ions.
TEQOYA ionizers are 100% harmless. The safety of negative ions, even in very large quantities, has been established by numerous studies. TEQOYA ionizers do not emit ozone: laboratories that have measured ozone a few centimeters from a TEQOYA device report a density of less than 2 ppb, in the order of the accuracy of measuring devices. Our devices have extremely low power consumption and the electromagnetic radiation emitted is also extremely low.The electric current thatair purifiers TEQOYA can generate is 1000 times inferiorat the threshold of danger of the electric current for health (1mA).
