I recall many years ago when I asked an instructor about a freediving course he asked me weather am i a smoker or not , even before ask my name …. I assume that he imply that i cann’t be a freediver if I smoke , fortunately I am non smoker , after a year or so , I do a freediving course with a freediving instructor trainer and I shocked to know that he is a smoker , even he smoke before the diving … and i told my self Ok , he may can couch freediving , but as a smoker he cann’t be a professional freediver … but after that I know that he made warm up dive to the natural buoyancy point and stay for more than 6 minute , I get confused , is this a green light to smoke if i want and still have the opportunity to be a professional ?
thank you FreediveInternational
Smoking is bad, always, not only for freediving. If your instructor would not smoke he could do even longer dives. Your breath hold ability is defined mainly by 2 factors, the mental one and the physiological one (meaning how good your body is to carry oxygen to your body and deal with low levels of oxygen).
you can have a very strong mental attitude, which can overcome your physical shortcomings, but if both your mental and physical conditions are top then you will be a better freediver.
Smoking impairs your cardiovascular system, there is no doubt about that, so it cannot in any way be an advantage for a freediver.
