Harmful Effects of Positive Ions
Why are Negative Ions so Important

What are Ions?

Ions are floating in the air around us all of the time and have either negative or positive charged on them.  Changes in their concentrations or in the ratio of positively to negatively charged molecules can have remarkable effects on human body.  It is known in science that ion depletion is the source of a wide range of human health problems, both mental and physical.

These air ions are important to you because if they have a high proportion of negative ions in the clusters you will feel lively, uplifted and enthusiastic.  Too many positive ions in the clusters will have you feeling depressed, lethargic and full of aches, pains and complaints. 
positive ionPositive Ion: an atom (or molecule) that has lost one or more electrons due to a high-energy impact. Natural forces that generate positive ions include the decay of radioactive minerals, radon gas, forest fires, lightning and ultraviolet rays.

positive ionNegative Ion: an atom (or molecule) that has gained one or more extra negatively charged electrons. Negative ions are naturally generated by evaporating water.

Electrons are highly sensitive to shock, impact, electric current and atmospheric change. Air pressure or heat, for instance, can cause electrons to escape from atoms and dissipate, increasing the number of positive ions in the air.
As mentioned above, the balance of negative and positive ions in the air is easily disturbed. A good example of this can be seen in the changes in ion levels associated with storm activity. Several hours before a thunderstorm, for instance, low atmospheric pressure causes the number of positive ions in the air to increase dramatically, to levels that sometimes exceed 5000 ions per cm³. In contrast, during a storm, negative ions increase to several thousand per cm³ while positive ions decrease, often to below 500 per cm³. (You can detect similarly high negative ion concentrations near waterfalls - see the chart below.)

In our daily lives, as well, we can directly experience the electricity of ions in the air in the form of static electricity - especially in winter, when the air is dry. Static is caused by a high ratio of positive to negative ions because of a lack of moisture in the air.

The Ratio of Negative to Positive Ions is Crucial to Health
The ratio of negative to positive ions is crucial, because negative ions are able to neutralize the harmful effects of positive ions. At the beginning of the 20th century, the ratio in the atmosphere was 1.2 negative ions for every positive ion. However, in recent years, the ratio has reversed and now there are 1.2 positive ions for every negative ion. This is due to environmental hazards such as air and water pollution, electromagnetic fields, and other factors.

Positive and negative ions also exist in our bodies, and the ratio of ions in the air we breathe influences the ratio in our bodies. Ions enter the body through the lungs (inhalation) as well as through the skin - especially through meridian (acupressure) points, which have weak electronic resistance. Then they travel through the blood and lymphatic systems to cells throughout the body. Using RELTEC IONISERincreases the number of negative ions absorbed into the body.

(These measurements were taken in Japan)

In some offices with computer stations, no negative ions were detected at all! Inside typical Tokyo residences, positive ions were found to be 500 times more numerous than negative ions. These findings may be due to inadequate ventilation both in office buildings and energy - efficient houses, as well as from the use of electronic devices that generate electromagnetic fields and from building materials that emit formaldehyde and other toxic fumes. On the other hand, high negative ion levels, such as at waterfalls, hot springs and other highly moist areas, will neutralize positive ions, leading to very low positive ion levels. 

In any case, these measurements suggest that it is difficult to maintain sufficient levels of negative ions in the present age.
