lons are natural particles in the air that have either a positive or negative charge. Negative ions in air collide with airborne
particles such as dust, pollen, bacteria, and smoke. The aggressive negative ion gives up its charge to the polluting particle
creating a new negatively charged particle, which continues to attract positive particles until the particles become heavy enough
to fall out of the air we breathe.
Literally hundreds of papers dating back to the 1800's have been published by peer reviewed professional publications on the
positive effects of negative ions. All the research seems to report on the following benefits to negative ions:
Mood Elevation
Relief from Headaches
Increased Alertness
Vitality
Increase in Fruit Shelf Life
Better Sleep
Reduced Depression
Reduced Allergies
Reduced Bacteria
A Well Being Similar to Being at a Mountain Waterfall
One simple explanation to these euphoric claims might be based on the following scientific facts:
The normal negative ion count in fresh country air is 2,000 – 4,000 per cubic centimeter.
The negative ion count at Yosemite Falls is over 100,000 per cubic centimeter.
The negative ion count in a normal home or office is less than 100 per cubic centimeter!
One interesting study indicates that increased negative ion counts have a strong positive effect on 25% of the test subjects,
a noticeable positive effect on 50% of the test subjects, and no effect on 25% of the test subjects.
