What are ions?

What are ions and where can they be found?

Ions are molecules, which have at least lost or gained one electron and are therewith either positively or negatively charged and thus polarized.

Relatively many negative ions can be found in mountain and sea air but also in the skies after a thunder storm caused by UV radiation, lightening and tiny water droplets that react with air molecules.

Ions always strive for a neutral position. Some will be neutralized immediately after they originate and others have a longer life-span depending on the circumstances.

Ions are capable of bonding to aerosols – those are solid or fluent substances in gases – as well as to dust particles. These will become heavier than the surrounding air and then descend. Ions will also bond to bacteria and germs of diseases and eliminate them by electrical charge.

What is the effect of ions on humans?

Biology scientists have been able to prove that negative oxygen ions in our respiratory air are of vital importance to the metabolism. With the help of oxygen the body burns food elements such as fat, carbohydrates and proteins and turns them into carbon dioxide and water. Inhaling ionized air will improve the oxygen levels in the blood, which will make the separate organs function better and the overall cellular metabolism will improve.

Mind you, oxygen is only biologically active when it is negatively charged.

The worst “ion-robbers” are electrically charged synthetic material surfaces, house dust and electrical appliances. When there is a shortage of negative oxygen ions many people suffer nervousness, feel depressed or tired, have a disrupted night’s rest or have a lower physical or mental resistance.

The best way of keeping the air healthy is banishing the “ion-robbers”, to regularly ventilate the space and use natural materials.

Scientific research shows that revitalising the air with negative ions has a positive effect on humans. There is a distinct increase in resistance, an improvement of concentration and an increase of joy in life.

When the ion levels are disrupted – the air contains too many positive oxygen ions, e.g. when the weather is changing – health problems such as ‘not feeling too good’ regularly occur. These complaints can range from a dry throat, a stuffed up nose, an overall touch of flu, fatigue, sleeping problems, to headaches etc.

Concentration – Correlation

  • Up to 50 ions/cm3 cause physiological disorders
  • 1,000-2,000 ions/cm3 is the minimum quantity for a healthy living environment
  • 5,000-50,000 ions/cm3 improve the self resistance and the general resistance
  • 50,000-100,000 ions/cm3 terminate bacteria and decrease sources of infection
  • 100,000-500,000 ions/cm3 improve the healing process of the body

The below mentioned benefits are present when the air contains negative ions:

  • the indoor air gets cleaner and thus is better for your health,
  • the body’s resistance increases,
  • inhalation allergies can decrease or disappear,
  • anxieties and depressions may decrease or disappear,
  • diseases may be prevented.

NNegative ions are constantly in motion. They fly all over the place, distribute their charges and with high speed collide with anything present in a space. If the skin is touched the effect compares to that of a massage. The saturation of the skin increases which means that the skin will look better, hair growth will increase, resistance will increase and allergic reactions will decrease.

Bronchial tubes, activating the epithelial cilia

Tiny hairs in the nose, the farthest part of the oral cavity and in the trachea must protect us from infections. Each hair grows from a single active cell. Air pollution and a shortage of negative ions will cause the epithelial cilia to stop moving and render them useless.

But if air with negative ions enters the bronchial tubes, the epithelial cilia will stand up at once and start moving as if they were tentacles. They seize the dust particles from the air that is inhaled and retain them. By means of saliva and exhaled damp air the contaminations are discharged. afgevoerd.

Lungs, mucus dissolution and purification

The positive effect negative ions have on the lung function has indisputably been verified. For negative ions it is easy to reach the alveoli. The negative charge of the oxygen atoms stimulates the purifying power of the lungs. Slime will dissolve and contaminations will be eliminated or coughed up via the top airways in the throat after they have been absorbed by the free macrophages and the alveoli have positioned them on the epithelial cilia.

Blood circulation, embolism, thromboses

The human body has about 600 million alveoli with a surface of about 100 m2. From the alveoli oxygen is absorbed with the help of red blood cells (haemoglobin) and will reach the cells through the blood circulation. There are blood platelets that produce thrombogenesis for clotting the blood. When the blood platelets are not charged properly they will curdle and clot tiny veins. Thanks to the negative charge clotting is prevented because they now reject one another. If the charging potential is missing there is danger of thromboses and embolism.

Electrical potential difference for cells

Each healthy body cell has a cell voltage of -50 to -70 Mill volts. When exhausted this value drops to 0 Mill volts and can even turn positive. Thanks to negative oxygen ions the cells can be ‘recharged’ time and time again. The cells needs oxygen for their metabolism because oxygen breaks down fat and carbohydrates. As a result carbon dioxide leaves the cell via the body’s lungs. Newly adsorbed negative oxygen revitalises the blood and enters the cell. We can describe the metabolism simplified: Carbohydrates from food and oxygen reach the cell. Both will burn releasing carbon dioxide via the blood and through the lungs. For cancer cells this is different. These cells do not burn oxygen which means that carbon dioxide is accumulated. Moreover, negative oxygen stimulates the production of zytrochrom C, an important substance for several processes within the cell.


Hormones are created in the hypophysis, an organ of a mere 0,6 to 0,8 grams in the lower part of the brain. Despite its slight weight and size it is the supplier of vital hormones that make the adrenal glands, the thyroid gland and the reproduction system in both men and women work. Other hormones in the hypophysis take care of muscles, creating blood vessels, peristalsis, operating the gall bladder and kidneys, but also the light sensitivity and therewith the tanning of the skin. For producing these hormones the electrical biological processes are responsible and a direct relation can be acknowledged between these processes and the air that is inhaled.

Stress and serotonin

The ‘stress hormone’ serotonin is created in abundance with actual stress and also with avoided stress and can then be found in the thrombocytes and neurons. It will very much stimulate man but it also has negative consequences. Arguing, great agitation, joint pains, depressions and headaches can be caused by high levels of serotonin in the body. Another substance, mono-amine-oxidases, breaks down serotonin. Negative oxygen will stimulate the creation of mono-amine-oxidases, a substance that is created by the body itself.

Allergies and ions

Chemicals, synthetic materials, fertilizer, pesticides, various exhaust fumes etc. have dramatically deteriorated both the indoor and outdoor air. By inhaling polluted air the body will be more heavily burdened and will experience more stress.

However, the influence we have on the quality of the air we breathe is minimal. Every day a person breathes about 10,000 litters of air. It will come as no surprise that many people suffer from respiratory allergies. But negative ions are capable of removing several substances that trigger allergic reactions from the air.

Ionized indoor air

By using an ionizer it is possible to create a similar dynamic balance between negative and positive ions as can be found in unspoiled nature. That is why it is significant to constantly leave an ionizer on in a closed space. A surplus of negative ions is never harmful.

Clean air, free of dust and bacteria

The air in homes and offices is full of tiny airborne particles. These particles are, amongst others, dust and tobacco smoke that carry bacteria, germs of diseases and viruses. Negative ions are capable of fusing these particles to larger parts which are too heavy to float and thus descend. By regularly cleaning the space using a vacuum cleaner or mop/ceiling-mop these fused particles are eliminated.

What is the effect of ions in nature?

In nature you will find 0 to 50,000 positive or negative oxygen ions per cm3. Because the relation between positive and negative ions is 1 : 1.4 there is a surplus of negative oxygen ions.

Below you will find an overview of the number of negative ions per cm3 in different places:
  • Waterfall, forest: 50,000
  • Mountains, sea: 5,000
  • City border, pasture, field: 700-1,500
  • City park: 400-600
  • Pavement: 100-200
  • City centre house: 40-50
  • Closed office with airco: 0-25
