ORIGINAL: AAkasha So the same thing applies to escape artists who do performances under water, some swimmers, and of course kids who play "who can stay under water longer" at the community pool? I am not being inflamatory, I'm asking a serious question. Actually, Aakasha, the same thing -does- apply to escape artists. If they are unable to get out of the anoxic environment, lose their "calm" and start to fight their captivity, the anoxia can kill them. For voluntary breath-holding, it's a little different. The body will not allow, under normal circumstances, anoxia to continue past the point where there would be brain damage and death -- also, as the neurologists explained to us, when we hold our own breath, our body actually -relaxes-, in an attempt to conserve oxygen. Blood vessels expand, increasing the oxygen flow to the brain, and the body responds by reducing oxygen flow to muscles and other organs and increasing it to the brain. With -involuntary- anoxia, the body goes into -fear- mode. Instead of reducing the required oxygen, the body actually -fights-... the heart pumps much harder, blood vessels constrict to the brain in order to provide oxygen to the muscles so the person can fight and flee. According to the neurologists, that is why involuntary anoxia is much more dangerous than holding your own breath -- not to mention that, if you're holding your own breath and you pass out, you'll automatically start to breathe again. The risk with self-anoxia using plastic bags, rope, etc., is that you'll pass out in the anoxic state and not be able to free yourself before you die of oxygen deprivation. Calla Firestorm
