I have now begun training, or at least practicing my apneas more often. Since I have a heavy studying schedule I am limiting myself to static apnea and getting back in shape. Yesterday I decided to evaluate my current times. I was happy to see that after a year of absence I had been able in a few weeks to work up to a 3 minute static time. Which is my so far all time best. I also remember that I had never used hyperventilation and decided to give it a try. I am firmly against the use of hyperventilation in diving since we have so many risks already there is no need to up the odds. But I had never tried it in static, and to my surprise I managed to reach 4:15 (about 20 convulsions, first one would hit around 3:00). This was like reaching a dream of breaking the 4 minutes barriers, something only thought of in my imagination. I used to smoke as well so reaching such a time was something I thought I would never be able to do, especially only after a couple of years of quitting.
I was in for a surprise though.
I hyperventilated three to five times for each breath, measuring the effects and so on. However, a unexpected side effect occurred. About 5 seconds in each attempt I got terribly dizzy, not exactly dizzy but a feeling like a was being electrocuted, huge buzz in other words. To be specific on the 5 breath hyper.. the buzz spell was strong that if someone was in front of me I doubt I would be able to respond to them. Among other things I would forget the time I would begin the apnea, thus the reason for the three consecutive apneas. All had plenty of time in between, yet all resulted to some degree of this effect. The effects would only last about 20-30 seconds as far as I can tell. After which I would feel totally normal. The only other feeling would be a peculiar feel of temperature variance in my chest, as if in some parts the inhaled air were colder. Towards the end of the apnea the temperature variance would be felt in airway passage.
I tried to understand why this happened, so I traced one possibility to a breathing preparation technique in which you inhale fully but exhale somewhat slowly. It is supposed to increase your times about 10-15%, and among other things help you relax. So I thought that could be the reason, yet I tried it with and without the above preparation with mixed effects, once it occurred while another time it didn’t.
So I am left somewhat wondering why this would happen. The only other reason I could thiÐÞ

, maybe I needed short ones. I am not sure and to be honest I wont be using the technique since as far as I know it doesn’t increase your tolerance, it just increases time. Which is really something I would rather do only if needed (competition, heavy training to see limits and so on). One thing I got afraid of is passing out and without a buddy, (bed apnea) I got scared it could be dangerous. If anyone has any helpful info, advice or answers I would love to hear them.
Thanks in Advance,
