This is a long one, but he does shed some light on that here:

OK....Interesting,,,
I watched enough of it to come to a assumption that would need to be fleshed out, but it appears that it’s not the Ozone per say, as a gas like CO2, that is having a positive effect, it is the bodies’ reactions to it. It’s apparently a secondary effect.
For example, I am a smoker.
If I go to a doctors office and he/she does blood tests, one of the things they will find is a high red cell count, much higher than normal. They actually say that I will feel a lot better if they remove some blood.
This is due to Carbon Monoxide and CO2 in the blood, and that stimulates red cell production to increase the O2 availability for the cells. Even though they had enough to operate properly.
It appears that Ozone may well be doing a similar thing and perhaps stimulating additional processes that for some reason in some people may not be adequately performing.
