I have a close friend, an anesthesiologist, who is aware that I enjoy freediving. He thinks that breatholding on a repetitive basis is bad for the brain over the long term. I asked him if he had read some paper documenting this, but he could not relate a reference, saying instead, "it's just not natural."

I was wondering if any one out there is aware of any evidence supporting, or discrediting his position. I know there are many freedivers with many years of apnea under their respective belts, so I wouldn't imagine that it is a problem, but thought I'd still ask.

I don't post much, but I read the message boards frequently and have found this site to be an incredible resource. Many thanks to the staff.
