Tired after diving

[philliplehman]

Why do you sometimes feel so tired after diving? I am not talking about strenuous conditions diving, warm water, no current, no deco etc.. does it have something to do with the body eliminating excess nitrogen?

What do your dive/ascent profiles look like?

 

[philliplehman]

simple Nodeco dive profiles for example 20mtrs for 40mins ascent rate would be 10mtrs/min or less (using a Nitek duo) 3min safety stop. Then maybe a surface interval of 2 hrs and then another dive to 12 mtrs for 40mins. Also I get tired sometimes after a 1.5 hour dive at 5-6 mtrs (shallow but long cave) I could never really figure out why. My dive buddy also feels the same. I am fit and surf almost everyday so it is not a fitness issue, but diving is sometimes as tiring or more than surfing,

IMO it's a hydration problem,just drink more water/juice before and after the dive.
And don't forget that nitrogen is a sleeeepy gasszzzzzzz.

Thanks for the advice, I do drink before diving but maybe not enough. I will drink more (water/juice that is) and see.

I get dog tired after running checkouts. I've found ascent rates, yoyo profiles and lack of stops to be the main issues. When diving for myself, I have found deep stops and an excruciatingly slow final ascent to put me on the surface ready for the next dive or drive home.

I to get very sleepy after diving. Part of my problem is I don't sleep well the night before because I am so stoked to get wet. I went 2 dives yesterday with just a little over in hour of underwater time. When I got home I went to sleep for over 12 hrs. (forgot to set the alarm)

I have also found that adding a couple minutes of stops around 12m/40' and 9m/30' in addition to the normal safety stop did a lot to eliminate post-dive fatigue.

On 90 or 120 minute dives I'll drink a Capri Sun juice pack around the 60 minute point. I don't know if it is the liquid or the sugar content, but that helps me on long shallow dives.

Slooooow down the ascent, will do wonders for you after the dive.

I agree with the slooooooow ascent. I dove the Galapagos about 2 years ago and thought it was the nitrox. Last October I was diving the channel islands with a boat full of Instructors and DM's and they each told me to think about he ascents, and I agreed, they were sloooooooooow.

I used to get so tired that I go to a motel right next to where the boat docked. Now that I do sloooooow ascents, I can join the group for dinner and still drive to the cheap motel up the road.
