Benefits of air ionisation in the sport sector


British researchers at the Centre for Sport and Exercise Sciences in Liverpool exposed male subjects to NAIs and measured physiological responses, including body temperature, heart rate and respiration, while at rest and during exercise. NAIs were found to significantly improve all physiological states, particularly during rest. Most important was the finding that NAIs are "biologically active and that they do affect the body's circadian rhythmicity."(Reilly, 1993)


Russian researchers published numerous reports indicating that even brief periods of negative ion exposure (15/day for 25 days) resulted in improved responses to training in runners, boxers, swimmers and other athletes.
