I'd like to see any evidence that there is truth to your statement, please. I'll look at it if it's there.Originally posted by OKLA-ALASKA
. Ofcourse blacking out for a while is going to disrupt many things besides just brain cell
You shouldn't even be out there. The best in the world have never blacked out or if they have it hasn't been for a long time.
This is something I find very hard to believe. I have heard of almost all major Freediving athletes blacking out at some point in their career.Originally posted by OKLA-ALASKA

Then I should be fine, as even I don't do more than a few minutes!efattah said:Brain cell death begins after 'anoxic depolarization', which begins several minutes AFTER BLACKOUT occurs. So, if you routinely black out for more than a few minutes, you will be damaging your brain cells. If not, you should be fine!
I would be surprised if people who freedive as a career suffer repeated blackouts. Neurological DCS would be more likely. Although they may do much more freediving than anyone else, they probably don't reach the limit very often, as their aim is not to go longer or deeper than anyone else. Therefore if anyone has a problem, it would be competitive freedivers who frequently push themselves to blackout/LMC. I haven't seen any evidence that competitive freediving is harmful.JasonWelbourne said:My brother, who is a fan of extreme SCUBA diving, has this idea in his head that freediving = brain damage because he has read or heard somewhere that Asian freedivers who do so as a matter of career (pearl divers or whatever) have been found to suffer from brain damage in relation to longterm freediving. I have repeatedly asked him for a reference as to where he heard this, and have tried explaining to him that if that were so it would be due to longterm blackout problems or neurological DCS, which he would be just as prone to get himself in the right circumstances.
