ORIGINAL: BitaTruble ~FR~ When your hands are over your head, you are hyper-extending your lungs and chest muscles which makes it more difficult for the blood to circulate. Not only does that prevent enough oxygen from getting to your brain, it makes it harder for the blood to leave and make room for new, oxygenated blood to get to the places where it needs to be (like your brain!) Get yourself a copy of Grey's Anatomy (one of the absolute BEST BDSM books on the market today) and study up on human anatomy. Alternatively, a copy of Human Anatomy & Physiology by Elaine N. Marieb and Katja Hoehn is also an excellent resource for SMers. Some things you can try - keep hydrated, make sure your electrolyte levels are normal, limit the time you are in suspension, don't drink the day before you play and has already been suggested, check with your doctor to make sure there isn't some underlying causal factor to your dizziness rather than the suspension. Google keyword 'cruxifixtion', 'blood pressure', or perhaps 'suspension' and arm yourself with knowledge. Consider with going the harness route if over the head suspension isn't viable for you or even short term inversion and other activities. There's a ton of stuff to do out there and you'll only be limited by your own creativity and your body protests. :) Good luck. If prolonged, crucifixion kills through pulmonary edema, the lungs fill with fluid and you suffocate, if you have pre-existing circulation problems then you might get into trouble more quickly. Wikipedeia is not backing me up on this however, I'll have to do more research - they cite dehydration and shock, but then contradict themselves with: quote:
Crucifixion on a single pole with no transom, with hands affixed over one's head, would precipitate rapid asphyxiation if no block was provided to stand on, or once the legs were broken.[link=http://en.wikipedia.org/wiki/Crucifixion#cite_note-John-29][/link] Which implies suffocation as the cause of Death when suspended with ones arms over ones head. Note "rapid".
