Last week I was doing dry statics at my computer. The max for this series of 8 breath holds was 4:00 minutes, which I had done before in a pool. This time, however, I 'packed' my lungs with around 5 xtra sips of air just before breath hold #6....
I remember trying to get up off the floor but my head kept banging into the bottom of my bedframe, as my bed is next to my computer. When it stopped, I calmly thought to myself that I had just had a convulsion. I was not droopy, foggy or anything other than feeling normal. I checked the elapsed time and found I had went down around 10 seconds into the hold.
Now, a week later I did the same series of 8 and again convulsed. This time my wife saw it. She said my head was banging over and over again into the keyboard. I could hear her yelling my name but could not lift my head without it crashing back down. I came out of it fine again but a little spooked.
I believe it was the combonation of 1. Hyperventilation in the last 20 secs before starting these breatholds, and 2. Packing the xtra 5-6 more breaths on top of already full lungs caused them to press into my hearts left ventricl, resulting in reduced bloodflow/02 to my brain. The two things in tandem spelled 'whiteout, or convulsions.' I came to this conclusion based on the fact that I have been doing Apnea tables for over a year with zero problems, yet the two time I throw PACKING into the mix I go into convulsions 1/2 way through the table.Packing may be fine for most, but this practice, along with hyperventalation, are now out for me. I am going to train for lowering the heart rate and continued C02 tolerance training on a single, deep breath.
