Ozone sauna and chronic fatigue
An example of contemporary diseases is chronic fatigue syndrome.
With this disease, people feel tired even though they are not doing work that requires fatigue. In fact, although they didn't move at all that day, they felt exhausted as if they had carried a ton of weight and they certainly didn't even have the strength to move.
Ozone can provide significant improvements in chronic fatigue syndrome and can significantly erase the bad effects of the disease in the body, starting at the cellular level.
