Hi
Recently I found a site on the internet, written by a Dr Win Wenger, claiming that held breath underwater swimming increases your IQ via vasodilation of the carotid artery (the artery going to your brain) and that:
"For accumulating 20 hours of held-breath underwater swimming within 3 weeks from start to finish-- you will experience:
* the previously-promised 10 or more points I.Q. gain;
* better span of attention; better span of awareness;
* better awareness of the interrelatedness of things and of ideas and/or perceptions;
* finding yourself way better at winning arguments or disputes!"
You can read it at :

He quotes a scientific article. I only read the abstract. It agrees with the dilation effect, but makes no further conclusion as regards to any effects on IQ. Here is the URL:

I don't freedive (yet). I am practicing the underwater swimming slowly in my school pool. (I'm a teacher in Japan). Recently I became interested in this and other ways to increase IQ. I'm a skeptical person but I'll try anything once. I notice that my breathing is getting easier and I can read things faster, although whether this is due to the swimming or something else I don't know.
I don't push my times. I only stay under for 45 seconds max now. Yet I experience slight headaches every evening after the underwater swimming. I follow techniques for freediving, slow movement, relaxed body, etc.
So, does anyone know anything about this? Have you noticed any changes in your IQ or perceptual abilities? Any scientific studies?
Any help greatly appreciated.
