Is this real? I mean, "Chronic illness and behavioural problems are caused by chronic overbreathing". Says who? There's a footnote lower down but no evidence for this wild statement is given. Chronic illness and behavioural problems are caused by a million and one things but I wouldn't have even put over-breathing on the list! In fact, if anything, I would have thought that the reverse is true, ie chronic illness and behavioural problems can cause "over breathing" (do they mean hyperventilating?). Sorry to be such a cynic.
well, i'm willing to try anything for my horses, especially if it's free (!), but i think the wild claims of how beneficial it is to the health are a bit much! i can sort-of see that depriving the horse of half its oxygen might make it a bit more amenable though...!
