Folks,
Having been somewhat condescendingly yelled at by captain for doing something I do pretty regularly, I thought I'd see what the Internet had to say about freediving after scuba.
What I've found is a whole lotta people who say things like "Dude it's a horrible idea. Why would you risk it?!?!" and very little hard data suggesting either cases of DCS that can be directly attributed to the rapid recompressions / decompressions associated with freediving during a period of high nitrogen loading in one's body, or controlled studies that support well-founded conclusions.
The more scientific material I did find suggested at best that there's a potential risk - albeit a minor one - associated with mixing the two but that there's not a lot of actual data so it remains in the realm of the theoretical.
Have I missed something? Is there better data out there to help guide one's decision making? Realistically we all take calculated risks every time we jump in the water. The key is having good data to do the calculating. I'd like to get past the people who vociferously advocate extremely conservative practices in the absence of data, and get to where I can make more informed risk management decisions.
Best,
-Ben
PS - If you're wondering what I got yelled at for:
We did one 35 minute dive to 80' or so. About 40 minutes into our surface interval I got too hot to sit on the boat and swam around a bit. Dropped to maybe 30' a couple of times only to get screamed at. Seems a bit extreme to me...
