Causes and effects of negative ion exposure and depletion

EFFECTS OF NEGATIVE ION EXPOSURE

Studies have shown that some people become very depressed when negative ion counts are very low, or in the wintertime (seasonal depression).

A high negative ion exposure appeared associated with feeling better about self, less sensitive, and more responsive or innervated (energized). -From August, 1982 issue of Aviation, Space, and Environmental Medicine.

"Results indicated that subjects had faster reaction times and reported feeling significantly more energetic under negative Air Ion conditions than under normal air conditions."
  - From Influence of Negative Air Ions on Human performance and Mood.

"... The introduction of negative ion generation increased the subjective rating of alertness, atmospheric freshness, and environmental and personal warmth.

"Fresh country air has negative ions that have been demonstrated to both treat and prevent depression."
From Depression: The Way Out, by Neil Nedley, M.D. ^REF

CAUSES OF NEGATIVE ION DEPLETION

The picture tubes (CRTs) in computer monitors and TVs deplete the air of negative ions.

So does the airflow through furnace ducts and air conditioning systems.

Research has also shown that polluted areas both indoors and outdoors have very low levels of negative ions, and very high levels of positive ions. It would seem that all or most of the available negative ions had been used up in their fight with contaminants. Dry hot winds (like the famed Santa Ana, or Witches' Winds) also deplete negative ions from the air.
