arious human activities and electrical appliances produce positive ions which are the reason for the deterioration of our physical and emotional well being; eg discharge of voltage in high-voltage networks, heating and cooling systems, TVs, radios, transmitters, radar systems, computers, exhausts and cigarette fumes.

Scientific tests have revealed that the ratio of negative to positive ions should be between 1.02 to 0.98 and the air's composition of negative ions should range between 1000-1500/cm3. Measurements have shown that the number of negative ions decreases to 200/cm3 in a closed room containing several people.
