Hey! Thanks for posting this; myself and all the crazy fans of polyphasic sleep loved to hear it. ;) Though you may find the Uberman Sleep Schedule the most interesting (because it involves replacing all of your sleep with 20 minutes every 4 hours…I and others have done it for 6 months and more with huge positive effects), almost all polyphasic sleep schedules are based on increments of 4 hours, and naps of 20 minutes or “core naps” of 90 minutes. And to the best of my knoweldge, this developed without the knowledge of ultradian cycles! Really fascinating stuff. There’s tons more info out there on Uberman and other polyphasic lifestyles, but I humbly offer my website as a place to jump in…Besides being an Ubersleeper for 6 months a few years ago, I’m polyphasic again on a different schedule now and have been recording my experience & progress for almost 3 months.

Thanks again for the info, from myself and others on the Uberman Yahoo group!
