Negative-Ion Technology is found in more than one Nikken product category. Air Wellness® air treatment devices feature a generator for producing negative ions. Portions of the Kenko™ Sleep System and selected Nikken jewelry both include fibers that emit these ions.
Ions are charged particles, either positive or negative, that attain a charge through the loss or gain of electrons. A positive ion has fewer electrons than protons, resulting in a net positive electrical charge. Negative ions contain additional electrons, which provide a negative electrical charge.
These ions are essentially odorless, tasteless and invisible molecules. However, they may be observable as other phenomena, for example as static electricity.
Positive or negative ions enter the body, as do other air molecules, through inhalation.
Presence of ions in the environment
Ions are created by atmospheric conditions that are either natural or man-made.
Electrical equipment is a well-known example. An electrical apparatus that uses or produces a significant amount of electrical current (for example, a large transformer), creates sizable numbers of positive ions. A noticeable effect is the presence of ozonated air (a detectible “electrical odor”) near electrical machinery in operation.
In contrast, there are natural conditions that increase the amount of negative ions. Elevated numbers of negative ions are present in the air in forests, the seashore, and near waterfalls and other natural water features.
Effects of ions
Frequent exposure to electrical equipment in operation has been reported to cause a feeling of fatigue or illness. This is believed due to the positive ions generated by the apparatus.
Negative ions appear to contribute to positive changes in mood and behavior.
Another way that negative ions may promote heath is that allergy-provoking particles such as dust and pollen possess a positive electrical charge. When negative ions are introduced to the environment, they appear to counteract the allergenic effects of these positively charged ions.
