A detailed description of polyphasic (nap-based) sleep schedules, including the Uberman, Everyman and others. Written by Puredoxyk, the coiner of the term "Uberman's Sleep Schedule" and a polyphasic sleeper for many years, the book covers the history of polyphasic sleep, how to decide whether to be polyphasic, extensive advice for adapting to polyphasic schedules, and information about living polyphasically in the long-term.
The Second Edition includes tons of new content (many expansions, plus whole new sections on athletic lifestyle, sleeping in public, and more), brilliant new formatting and typesetting, and a brand-new cover!
It is somewhat mind-blowing to me that I lived for so long without ever questioning that "people just need ~8 hours of sleep". Polyphasic sleep sounds amazing and I definitely want to try it after reading about it!
This is a really good introductory book for anyone wants to know about polyphasic sleep (written by a very long experienced person who is Marie, the author, with different polyphasic sleep that exists there). it provides with the requirements for doing it and defining the reasons that need to be strong for switching from monophasic sleep into bi/polyphasic sleep, not only that it shares some useful techniques that can be used to fight the urge of wanting to sleep when you are feeling tired (which are tried personally and found to be useful), some ideas to fill up your time with when you have a huge amount of waking up time 18-20 hours till 22 hours ( when it comes to uberman schedule).. and many other tips and tricks that worked for the Author.
The reason for reading the book is because I needed an easy organized source about polyphasic sleep before deciding to try a schedule. The downside of this book is that it needs to be reviewed, a 3rd edition is needed concerning uberman since people in communities ( Discord server) they see is as an outdated one. Even before I finish reading the book I picked the Triphasic schedule which I have been going in for 2 weeks ( messed up few nights, so needs more time to be adapted), the author didn't talk about it at all, just mentioned it, but still, it's the only one that can fit my schedule, so I will keep this review updated when I'm fully adapted to it or dropped it ( hopefully not because I'm already enjoying it)
Very interesting idea and the ability to sleep for 2 hours out of 24 is incredible. I however won't be trying to do this since there's no studies of long term health effects and I would probably be better off managing the time I have than making the switch to uberman. I got this because I was intrigued by the uberman schedule(2 out of 24 hrs split into 20 minute intervals) but the book is also worth checking out to understand the more moderate polyphasic sleeping cycles.
Interesting, but must be taken with a grain of salt, mainly because of lack of proofs in form of scientific articles. New findings are suggesting long-term health effects resulting from several polyphasic schedules. Additionally it's commonly known uberman and similar, heavily reducing schedules are not sustainable in people without genetic abilities (DEC 2 mutation).
Fascinating self-experimential report and detailed guideline about polyphasic sleep schedules. Polyphasic sleep, as i recommend you to look up on Wikipedia, encompasses several sleep schedules with more than one sleeping phase per day. Typically, there is a core sleeping phase of a few hours combined with several powernaps of about 20 minutes length to replace a traditional monophasic sleep schedule where you sleep 6-8 hours once. This cuts down sleeping time ideally without significant fitness and alertness losses, enables a lifestyle of both early rising and night time activity, and provides a unique experience.
I've had some of the most motivated, fun, and project-y times trying out Ubersleep, and learnt quite a lot about myself and sleep. This is a rather short book that you should give a try if you don't think that 6-8 hours of core sleep are god given (as surprisingly many people do) and if you're not afraid to give your body a challenge and experiment.
The only negative point I see in this book is one of style: a severe excess of footnotes, sometimes of puzzling length. This makes for a difficult reading experience, which is why i recommend skipping most of the footnotes. This will be changed in the upcoming extended and improved second edition, which i'm very much looking forward to.
I read this book last year when I tried the Uberman sleep schedule; needless to say I crashed and burned after day 4 or 5. The biggest problem I have with polyphasic sleeping is the poor ROI for me personally. I only get about 6 hours of sleep each night as it is now, so I would only gain 4 hours each night. Add in deprivation and the huge scheduling inflexibility and you have the sure-fire makings of a waste of time. I would be better served by simply altering my current schedule to fit better into my 18 hour day. I can also try (and have) a more effective approach to organization, such as David Allen's Getting Things Done.
My biggest problem thus far has been the huge wall you have to cross between mono and poly. But once I'm there, I'm pretty much locked in and have no flexibility. So I guess it's just not the solution I'm looking for.
Anyway, I'm writing this review now because I got the book out again yesterday and skimmed through it, as I was considering SPAMAYL. But after a day of reading on the blogs and forums, I have reconsidered.
Clear, useful advice on shifting to a polyphasic sleep cycle.
The new edition of PureDoxyk's book isn't hugely different from the first edition (which I read a few months ago before adapting to the Everyman3 sleep schedule) but there are some additions and tweaks which make it an improvement on the first. Last time I read the e-version, so this time it was nice to have a paper copy that I could scribble in.
If you're interested in sleep modification (and being able to sleep only 2 or 4 hours per day without medium-long-term issues), give this book a read. If nothing else, it'll expand your sense of what is possible, and that's always a good thing.
It is really interesting book about fascinating sleep schedule. Based on experience of author and other poliphasic sleeper may be treated as great tutorial for interested ones. There is no a lot research mentioned as unfortunately there are no much of them at all. But still author tried to gather as much as possible of scientific info on poliphasic schedule. Probably every question you would have was answered than and also those you wouldn't figure out to ask. I regret that there is no more about biphasic sleep as I'm not able to use currently more strict schedule, but still it was really great book to read and I learn lot of fascinating things about sleep.
I am fascinated by Polyphasic sleep. Puredoxyk is the first layperson to really experiment with it as a lifestyle choice and her experiments have enabled many people to adopt this as a valid lifestyle. The book is clear, non-hyped, and documents her own discoveries. She is clear that this is not science, but more results of personal experiment.
Well written. Good humour. Very practical suggestions. A definite "must-read" before jumping into anything this extreme!
I really enjoyed this book. The material is really interesting and I thought it was presented fantastically. The writing is honest and speaks a lot from personal experience. It is also written so that it feels like light reading when you are actually eating a ton of information. It's also written in that amateur style where it gives links to the authors blog and asks you to contact them with questions or thoughts and is formatted in a personal way and I really like that in books.
Uno dei pochi libri che parla del sonno polifasico. Si contrappone a "why we nap" di Stampi (di carattere più teorico), fornendo le esperienze di una persona che ha dormito polifasico per circa due anni. Al lettore è in grado di trasmettere tutta una serie di consigli, tecniche e persino alcune personali varianti rispetto al classico "Da vinci sleep" (alias Uberman), assai meno impegnative.
Fascinating insight into polyphasic sleep, and extremely practical. I'm looking forward to edition 2 of the book being released in May, but for the moment it's given me a lot of advice and suggestions for my own experiments in polyphasia.
