Science and Research on Negative Ions Benefits

Influence of Negative Air Ions on Drivers

R & D Review of Toyota CRDL, Vol. 37  No. 1 (2002.3)

Negative air ions are observed at a high concentration level in places such as near a waterfall and in a forest. Some studies have demonstrated that negative  air ions have positive effects on human performance  and mood... (read more)

UV-C fluorescent lamp produces λ=253.7nm ultraviolet rays, are made of ordinary glass, through which UV rays can not radiate but be absorbed by fluorescent powder to change into visible light. While UV germicidal lamps... (read more)

Negative Ions for the Brain


The Owner's Manual for the Brain, Everyday Applications from Mind-Brain Research

The atmosphere we breathe normally is full of positive and negative ions. Air conditioning, lack of ventilation, and long dry spells remove negative ions, which usually serve to latch onto airborne dirt particles and wrestle them to the floor, rendering the air purer. Roughly one-third of the population seems to be particularly sensitive to negative-ion depletion... (read more)

Negative Ions and Positive Vibes

Technology Review, Jan 1983 v86 p74(1).

Negative ion generators are curious little devices--their manufacturers' claims are inevitably followed by exclamation marks. "Is your air healthy?" asks one ad. "Recreate fresh mountain quality air indoors!" Negative ions, say manufacturers, make you feel alive, revitalized, and alert while relieving depression, headaches, and allergies. Trillions of these incredible negative ions somehow are supposed to kill bacteria and make plants grow better... (read more)

Effects of negative ions on cognitive performance


Journal of Applied Psychology, Feb 1987 v72 n1 p131(7).

Abstract: Male and female subjects (undergraduate students) participated in two studies designed to investigate the impact of negative air ions on cognitive performance. In the first experiment, they worked on three different tasks (proofreading, memory span, word finding) in the presence of low, moderate, or high concentrations of such ions... (read more)
