I wasn't quite sure whether to put this here or is skepticism and debunking. Anyway here goes. I was reading the other day about this different way of sleeping that allows one to sleep just two hours a day. It is called the Uberman sleep schedule. Basically, one sleeps every 3-4 hours for 20-30 minutes and that is all the sleep that one requires. Read more on http://en.wikipedia.org/wiki/Polyphasic_sleep" [Broken] for instance. Google to find more.) I was just wondering how true this is? I don't see any studies done on this. I found http://www.supermemo.com/articles/polyphasic.htm" [Broken] write-up that claimed otherwise and all this was a myth. I don't know what to make of it.
