Although I have been diving for 4 years now, I just recently got Nitrox certified and plan to take my first dive with Nitrox next week in Bonaire. Does breathing nitrox really make you feel less fatigued than breathing air or is that just a myth ???

I personally think it's all in the head..Ive dove it many times and have never felt a difference..

I'm convinced that nitrox will make you feel better after a dive IF your ascent rates are too fast and your safety stops too short. i.e. the nitrox is stopping you from getting slight,sub clinical DCS.

If you are doing good profiles on air then you will not see any difference in fatigue between air or nitrox.

I dive EAN. I think it makes a big difference. I usually do 3 dives in 5 hrs. When I dove air I always had to stretch my surface intervals. I usually ended up with a pretty high Nitrogen exposure before the day was through. With Nitrox I can still dive 80-90 FSW for 40-45 minutes without getting into deco. JMO YMMV

From the tests that have been done on the subject, it appears to be a placebo effect.

Thing is, a placebo that works for you is just as good as a genuine direct physiological effect, don't you think?

I personally have not noticed a huge difference... but I feel sometimes like there may be a slight difference.

My wife swears she's less tired with Nitrox, I don't see any difference.
Different stokes for different folks I guess.

Use it for the intent of extending your bottom time and Shorting your SI and you will be more Tired cause you will Dive More

When I am diving a lot and using Nitrox has been on a live-a-board. I took lots of longer surface intervals. Otherwise if doing a series of dives over a day I might use either. We have not noticed one or the other.

Nitrox does make you lighter. I know after I've been diving it for a few days my wallet is definitely lighter then when I dive air.

I agree, this is the only way it could make a difference. That or just something to do with having less nitrogen loading on your body.

If you've ever breathed pure 02 on the surface you know you can't tell a difference from regular air.

If you have a head ache O2 will make you feel better. So I think nitrox COULD make you feel better. Personally I haven't done enough dives to really say from experience.

Well, I just did the math. I have done over 300 dives on nitrox. I know that my nitrogen loading is less than when I dive air. You can say that it is all hoohaa. But, to me, it makes a big difference. It's a big blue planet that we live on. There is something for everybody, out there. Dive what you are comfortable with :-)

I do dive nitrox, always. But I think the benefits only come from the reduced nitrogen loading, not the increased O2. After all, at depth, breathing even regular air is equivalent to breathing > 21% oxygen on the surface.

I usually dive nitrox and can't really tell a difference between air or nitrox.. but I don't use it for extending bottom time and what not.. just a safety margin. At resorts when nitrox air fills will vary from 30 to 38 I can't tell a difference between tanks either..

I can't tell a difference diving Nitrox, and some of my buddies can't either. I think it's placebo, but as was said before, if it works for you then it works for you.

Don't count on it though, it's in your head more than anywhere else.

thats the down side... expensive fills!!

In my limited time w/ EAN cert, I have found I seem to be able to tell the difference between 32% & 36% fills. Fills aren't cheap though

Fill price depends upon where you are. I have seen $8 fills and then $15. No difference on what PO2 you get.

Probably no true effect but who knows. Better yet, who cares, lets go dive.
