We feel on top of the world. Dr. C.W. Hansell, research fellow at RCA Laboratories and an international authority on ionization, illustrates the effect with a story about his ten-year old daughter. We were outside, watching the approach of a thunderstorm. I knew that clouds of negative ions were filling the air. Suddenly my daughter began to dance across the grass, a radiant look on her face.
Many doctors doubt their therapeutic effects.
But there is a growing army of people who swear by them. Fifteen minutes in front of the negative-ion machine and they feel so much better they don't want to leave. It was RCA's Dr. Hansell who, in 1932, stumbled upon the behavioral effects of artificially generated ions. He noticed a startling swing in the moods of a fellow RCA scientist who worked beside an electrostatic generator. Some days the scientist finished work alert and in bubbling good spirits.
