IMPORTANT DISCLAIMER: When dealing with polyphasic sleep, it is good practice to be skeptical about what you read, including everything you find on this website. Polyphasic sleep is not an exact science, because the number of scientific studies done on this subject is very limited. Consequently, while this content has been compiled with the intention that it might be helpful and useful to people, a lot of the information contained within has been collated without regard to perfect scientific accuracy (although, in many cases, published research papers have been studied to give additional background). Portions of the content on this website are a result of direct or personal observation and some information has been extrapolated based on data already available. It should also be said that I'm not perfect, and it's possible I made mistakes or I've misjudged the information. Nevertheless, hopefully you find at least some of the content within to be useful. If you feel the information given here is inaccurate, or that I am giving out bad advice, you are encouraged to discuss this with me over in the Discord chat room.
