Following up on the post 90 Minutes Sleep Cycle, I found out there are couple of sites and resources that talk about this sleeping hack. Technically, it is called Polyphasic Sleep. From Wikipedia, the definition is:

… Polyphasic sleep is a sleep pattern specification intended to compress sleep time to 2-5 hours daily. This is achieved by spreading out sleep into short (around 20-45 minute) naps throughout the day. This allows for more waking hours with relatively high alertness…

A while ago, Kuro5hin has a featured article titled Uberman’s sleep schedule. Ever since the article has been released, there are a lot of interest on polyphasic sleep – discussions are everywhere.

There are also attempts on testing and experiencing such method. Like recently in UberSleep.com, Nick Busey shows his efforts and experience on Polyphasic Sleep. Some people reported positively on such method, however some has bad experience on it:

… I spent 3 weeks attempting to adapt to the Uberman schedule, the major cause of my lack of function by the end was due to the slip up with the naps. My body never really had a chance when I gave it mixed signals as to when it could get sleep. I had a fair mix of good and bad days over the three weeks, the most depressing was the last week where I felt I was going backwards, not forward. Too many slip-ups that week left me disorientated and knackered. Before then, the first two weeks seemed much better, probably because my body was using up my energy reserves.

I may try the schedule again when I can dedicate a month to adapting. I am disappointed it did not work for me this time, what I shall concentrate on now is making sure I utilize my time effectively rather than trying to grab more.

Currently I am classified this as good to know, do not implement it yet. My concern of such method is the health issue associating to it. Does anyone have any information on this?
