Abstract
Theoretical treatment has been carried out to elucidate the physicochemical characteristics of corona nano mist sauna generated by method of water fragmentation. The size distribution of corona nano mist is ranging from 20 to 50 nm and the number of minus ion is approximately 10,000/ml. The main results obtained for the study show that the oxygen minus ion attached water molecules, O_2^- (H_2O)_n, which is produced from corona nano mist sauna, has a significant effect for human body such as the recovery of fatigue and the purification of blood.
