<p>I just read the article. I don’t get something. Blaine says he’d like to break the world record for staying awake (current record is 11 1/2 days) but that Guinness said it no longer acknowledges such attempts because of health concerns. So, if they stopped recording THAT for health concerns, what do you call holding your breath for 17 minutes under water? Healthy?</p>
<p>I saw this on Oprah today and although I can’t imagine it being one’s goal, it did seem that he went about the feat in a very responsible manner. had been training for 4 months, researched alot, acclimated himself to simulated very high altitude air, had doctors and trainers right there, etc.</p>
<p>soozievt: I suspect that the most present danger due to holding one’s breath is passing out from hypoxia, which would obviously result in one breathing again relatively quickly (passing out would obviously be the end of a controlled experiment).</p>
<p>However, in studies of extreme sleep deprivation in rats, unpredictable deaths occurred after about 2 weeks, with little to no warning, and other serious symptoms also occurred in rats (and in certain humans who have tried such things) with little warning or explanation. Sufficed to say that Guiness probably considers the unclear physiological processes that lead to the dangers associated with extreme sleep deprivation serious and unquantifiably dangerous enough to discourage attempts at that kind of record as strongly as possible.</p>
