Risks of dry apnea

[jac_r]

Due to time constraints, I am thinking of getting myself on a proper program of dry training, CO2 tables and max breath old.
I have been said that dry training is "risk-less", but how is it really? a blackout can happen right? even for a CO2 table isn't it?

Most freedivers have done dry training at some point. It is generally considered perfectly safe if you take steps to avoid "falling down" injuries. I myself have never heard of an actual example of some one getting hurt doing dry apnea training. I have heard of people standing up and doing breath holds and then waking up on the floor - and I suppose they could get injured that way.
If you are apnea walking, riding an exercise bike or some other movement, it is possible you could black out, fall over, bang your head, twist your neck, crack a rib, etc. But if you are laying down on your bed/sofa or sitting back in an easy chair - if you then black your body will automatically start breathing again and you will be fine. Also when doing tables at rest, holding your breath to the point of blackout is really hard to do - usually only experienced folks have the will power and stamina to do that.

Some people, mostly beginners, have been seriously injured with aggressive dry stretching. There was lung packing of some sort in all cases.

Dry apnea is pretty safe provided that you do it while laying down on the floor. This way there is no chance to injure yourself in case of a blackout. I advise against doing breath hold on a chair. First of all, it increases the chance of blackout considerably. Secondly, it increases the risk of problems in case of a blackout.

The only accident related to dry apnea I've heard of happened during breath hold on a chair. This person blacked out and fell off the chair in such an unfortunate way that his chest got stuck between the wall and a furniture. He was not able to breath normally and was found unconscious few minutes later. At the beginning his condition looked serious. Fortunately, all neurological symptoms resolved within few hours and there was no permanent damage to his brain.
