My mum and my brother have both had Asthma problems, but I have not - at least, not officially. Mega coughing fits when I am cleaning are not unusual, and I tend to react sensitively to cigarette smoke in the air - I used to have a permanent cough, which I stopped noticing, and I only realised it was due to my wife's smoking several months after she stopped, and it had gone away, until we visited her aunt and uncle (60 a day chain smokers).

Anyway, my point: swimming, specifically diving, is well known as pretty much the best thing to increase lung capacity. Sport, however, in general, is a good thing to do the same, and I don't mean pumping weights in the gym.

It just seems logical to me, that when you increase the lung capacity, a lung condition like Asthma is going to slowly/quickly disappear or be significantly reduced. This would at least tie in with what several of you have said in this thread, and would perhaps suggest that diving (certainly to low depths under watchful eyes) could even be considered a therapy for such conditions ... what do you think?
