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.

Tesla (1 hr 20 mins)

Adaptation difficulty: INSANELY HARD

Also known as: Uberman 4 or U4

Tesla is a rather ridiculous schedule designed by Sharif Olorin in 2009 which combines aspects of both Uberman and Dymaxion. It consists of four equidistant 20 minute naps (one nap every 6 hours) and NO cores, giving a total of 1 hour 20 minutes of sleep per day.

This schedule was NOT practised by Tesla - it just got named after him because Sharif thought he was cool. Tesla practicing the Tesla schedule is an urban myth.

I honestly haven't bothered to write anything else about this schedule, because I don't consider it to be even remotely viable. The creator of the schedule and his friend supposedly adapted to it for a short time, but I'm skeptical about that given how misleading the other nap-only schedules are when it comes to adaptation feelings. In the event that it turns out to be plausible for people to pull off, I would expect the basic mechanics and adaptation experience to be along the lines of Uberman, but far more intense. At any rate, I really don't recommend you try out this one at all (at least not before you've been successful with some other nap-only schedule first).
