Why is SMOKING bad for DIVERS? - Diving studies reviewed

#guedivers #doktorben #stopsmoking GUE is known for it's non-smoking policy - but makes it sense? Why is smoking bad for divers? And is it really that bad? In this video I go through scientific studies about smoking and diving and try to explain whether the GUE non smoking policy makes sense and if smokers really have more frequent or more severe scuba diving accidents. The beginning of the year is a opportunity to stop finally - just saying ;) Link to Allen Carr's book: https://doktorben.benjaminott.de/AllenCarr 00:00 Start 00:47 Welcome back! 02:16 Pulmonary Functions 05:00 Gas Exchange 07:05 Have smokers more accidents? 12:19 Vaping 13:06 GUE's no-smoking policy - Makes it sense? 15:14 Who is smoker? 16:32 I'm a smoker - what now?
