Tesla is an extreme schedule designed by Sharif Olorin in 2009 that combines parts of [[Uberman]] and [[Dymaxion]]. It consists of '''four equidistant 20 minute [[naps]]''' (one nap every 6 hours) and no cores, allowing for a total of merely 1 hour and 20 minutes of sleep a day. It is therefore referred to as '''U4''' (Uberman with 4 naps) sometimes.  

Tesla is an extreme schedule designed by forum user Sharif Olorin in 2009 that combines parts of [[Uberman]] and [[Dymaxion]]. It consists of four equidistant 20-minute naps (one nap every 6 hours) and no cores, allowing for a total of 1 hour and 20 minutes of sleep per day, the smallest amount for any recognised schedule. It can also be considered as a variant of Uberman, though with only 4 naps, hence it is also known as U4.

While [[wikipedia:Nikola_Tesla|Nikola Tesla]] was documented to sleep less than most people at night, he did not actually follow this polyphasic pattern. It got named after him by the creator. Here is what Sharif Olorin had to say about the naming:<blockquote>''“A friend of mine has recently switched from Dymaxion to the pattern I’m following. Now that I know of more than one success story with this pattern, I thought I’d better name it.''

Though [[wikipedia:Nikola_Tesla|Nikola Tesla]] was documented to sleep very little, he did not actually follow this schedule.

''So I give you the Tesla pattern. Because a) Tesla’s awesome and b) Tesla’s one of the few people known to sleep almost as little as we polyphasers.”''

As with all other nap only schedules, all or most [[wikipedia:Rapid_eye_movement_sleep|REM]] and [[wikipedia:Slow-wave_sleep|SWS]] requirements must be gained from the naps. At only 1 hour and 20 minutes of total sleep, the compression needed to achieve an adaptation to this schedule is expected to be far more intense than even that of Uberman and Dymaxion.

== Adaptation ==

== Adaptation ==

Olorin and his friend only stayed adapted on Tesla for only for short period of time. Feeling of restfulness on nap-only schedules can be misleading due to sudden changes between restfulness and extreme tiredness. The ability for REM sleep to enter the naps (and can give intensely vivid dreams) can create a strong illusion of the refreshing feel after that nap. It is possible that the both of them mistook the prolonged feeling of restfulness for adaptation while, in fact, they were still in the adaptation phase. A typical 20 m nap at first will grant the avoidance of SWS wakes for some time, but on Tesla, the soul-crushing sleep pressure will quickly place SWS at the end of each nap, resulting in abhorrent wakes from them. It is unclear if they have truly been adapted to the schedule according to current standards.

Other than the [[cold turkey]] approach, it ''may'' be possible to gradually adapt to Tesla, after one has completed an adaptation to Uberman, by cutting out 2 naps and slightly rotate the remaining 4 naps. However, no one has succeeded with this gradual adaptation method either.
