Diving after flying

Please can you advise me. I am flying out to Zimbabwe to night it is a 11 hour flight and I have an oppertunity to dive tomorrow on my arrival approximately 3-4 hour after landing.
Is this safe or not

Diving after prolonged flying may be relatively risky, considering the tiredness, the change in time zones and expecially the very frequent dehydration and upper respiratory tract dryness that accompanies prolonged flights. The position of DAN is to advice a period of at least 12 ( better 24) hours after the flight, with appropriate rest, nutrition and rehydration, before diving.

I am on a trip in Kenya, where I hoped to do some diving. The day after I arrived from France (March 8), after an 18 hour trip - 12 in the air - I became quite dehydrated, with diarrhoea, fainting, and general weakness. I was given dehydration salts and lots of liquid, and have been resting and seem virtually recovered. I do not want to do anything unsafe, but I would still like to do a few days of diving, and will be here until March 15, when I fly back up to the Masai Mara region (2 short 1 hour flights). I should also add that I am on a treatment for hepatitis C (Interferon and Ribavarin), although my doctor in Paris knew of no reason why this should effect my diving. I would appreciate a speedy response at this email
address, as I will feel more at ease diving with your blessing.



The situation you describe would seem typical of prolonged flights. In such cases the opinion of DAN is that a sufficient recovery, not less than 24 hours, should be allowed before starting diving activities. In your case the situation appeared to be somewhat more serious than simple post-flight fatigue and dehydration; I would not exclude a coincidental minor viral infection or a possible enhancement of the prolonged flight stress due to your hepatic condition.


If you are now feeling well and completely simptomless, I see no significant contraindication to resume diving, with the only advice to be quite conservative in your dives, both for depth/time profiles and for repetitive dives.


This is, by the way, a general practice of safety that we normally recommend for Kenya, given the perfectible condition of health care in that country and the limited availability of recompression facilities in the area.


I agree with the non influence of your current treatment for hepatitis C on the safety of diving.
