Uberman is the most widely known form of polyphasic sleep, with its appeal being the large amount of extra wake time it provides. For this reason, it is also one of the most widely attempted schedules by many first-time polyphasers.[1] However, the adaptation success for this schedule is few and far between, with virtually all attempts at the schedule ending in failure, since it does not meet the minimum sleep need for the majority of people.
Origins
A variant of this schedule, with 15-minute naps, was mentioned in Claudio Stampi's book Why We Nap, and was attributed to Leonardo da Vinci. As documented in the book, Italian artist Giancarlo Sbragia adapted to this schedule at the end of the 1950s, and stayed on it for 6 months.
The current iteration of the schedule is created and named Marie Staver (Puredoxyk) and her buddy Psuke Briah in 1999, drawing inspiration from a TIME article about Buckminster Fuller’s Dymaxion sleep. It was first revealed in a post on everything2.com in 2000.
Puredoxyk stayed on the schedule for 6 months in 2000 and she was not able to re-adapt to it later.
Steve Pavlina adapted to the schedule in 2005, and stayed on it for 5 months, and has not done it again ever since.
Mechanism
Since REM and SWS cannot realistically be cut, all (or at least as much as possible) of them must be accounted for by naps. The extremely low total sleep time means it requires intense sleep compression, possibly reducing the cycle lengths to under 60 minutes. After adapting, falling asleep becomes very quick and the transition to REM or SWS would also be almost immediate, giving nearly negligible amounts of light sleep. This would allow up to about 1h50m of REM and SWS combined. Even so, this is still far below the combined requirements for most people, which means REM and/or SWS have to be cut in order to maintain this schedule, which is considered unhealthy.
Living on this schedule requires constant maintainence of a delicate balance between REM and SWS pressures. Throughout each waking block, REM and SWS pressures build up gradually to very high levels and drops to more withstandable levels during the course of a nap, which would primarily contain the sleep type with higher pressure. Then, this reverses the ratio between REM and SWS pressures, so that the other sleep type dominates the following nap. It is also likely to experience mixed-stage naps, with both REM and SWS in the body’s effort to mitigate high sleep pressure.
Since maintaining the schedule involves such high levels of sleep pressure, circadian rhythm is much less important than on other schedules with peak-aligned sleeps, making it possible to have SWS-filled naps in REM peak hours and vice versa.
Adaptation
Adapting to Uberman is extremely difficult. While some people may claim that there is an easier method, that is simply not the case. Any methods of adapting to this schedule involves prolonged, intense sleep deprivation which is necessary to produce the level of sleep compression required.
Without previous napping experience, naps will mostly contain light sleep or traces of SWS. As the REM need is not being fulfilled, REM pressure quickly builds up to high levels, causing a REM rebound. This usually happens around day 3-5. This will appear to suddenly alleviate the sleep deprivation, making people prone to overconfidence about the adaptation. After this, naps mostly contain REM, and SWS pressure starts to build up. SWS rebound usually occurs on day 7-8 and it is the hardest part of the adaptation where most people oversleep and fail their schedules. After avoiding this first crash, subsequent crashes once every 2-3 days also needs to be avoided. REM and SWS pressure gradually reaches an equilibrium and the schedule is finally stabilized. This can take weeks and some may need up to 6 weeks on the schedule.
Human supervision
It is important to realize that willpower alone is not enough for adapting to this schedule. With SWS deprivation, willpower simply will not help you. People have reported unconsciously disabling or ignoring electronic devices and performing other actions necessary to go back to sleep, with no recall whatsoever afterwards. People have slept through noise-based alarms, flashing lights, loud fans, and repeated maximum-voltage shocks from a Pavlok. It is therefore very useful, if not necessary, to have constant human supervision to make sure you are awake when you are supposed to be. To date, most people, who adapted to this schedule, had the help of another human. Puredoxyk was woken up by Psuke and Youtuber Aeia was woken up by her twin sister during her adaptation. Without the help of other people, it is virtually impossible that you would ever adapt to this schedule.
Delaying the SWS rebound
It is possible to delay the SWS rebound by a few days by adding extra naps in the night for extra SWS gain during the first days of adaptation. Steve Pavlina used this method to delay his SWS rebound until around day 12. It is not generally a good idea though, since the rebound will eventually happen and doing this just drags out the adaptation process by a few days and overcoming the SWS rebound is essential to Uberman adaptation.
Gradual adaptation via rhythmic preservation
Exaptation
Naptation, in which naps are taken every 2 hours instead of 4 on Uberman, has been used to quickly learn napping. This may allow an easier start, as the ability to gain REM in naps would be present from the start.
Difficulty
Both Steve Pavlina’s blogs and Puredoxyk’s book Ubersleep greatly understated the schedule’s difficulty. Puredoxyk adapted to the schedule in times of extreme stress at university, and was unable to adapt to it again afterwards. Nevertheless, people tend to overestimate their chances of succeeding. There has been no detailed accounts of someone adapting to the schedule in more recent times. You may see many logs of people attempting this schedule, but most of them ends in just a few days, presumably because the author overslept and gave up. Those failures are often used to discredit polyphasic sleep altogether, without ever considering more reasonable schedules.
Lifestyle Considerations
Over the years, through anecdotes of adapted sleepers, the downsides of Uberman has been gradually discovered. These may include:
- little for exercising (especially with gaining muscle)
- tendency to gain weight
- near total inflexibility of sleep, even after adaptation
- 3h40m wake gap between each nap is usually too short for real-world commitments
Steve Pavlina worked from home when adapting to Uberman, and Puredoxyk also had a flexible job during her university years when she adapted to the schedule.
The harsh adaptation is extremely sensitive to skipping naps. As claimed by Puredoxyk in Ubersleep, just skipping one nap causes intense sleep deprivation, similar to when one skips a few nights of monophasic sleep in a row. Even after adaptation, the risk of oversleeping remains, and alarms may have to be maintained indefinitely.
As with other nap-only schedules, Uberman impedes the clearance of brain waste via the glymphatic system, because the longest continuous sleep block is only 20 minutes. It is therefore currently unknown as to how this schedule can be maintained, especially by those with average SWS needs. As such, only those with significantly lower vital sleep requirements should attempt Uberman.
Variants
Extra naps
Shorter naps
Why We Nap documented an anecdotal adaptation to this variant of the schedule. This sleeper, in his journal, recounted his adaptation to this Uberman variant that totaled only 1h30m of sleep each day, mirroring the alleged Uberman variant of Da Vinci. It took him 25 days to adapt, and he remained on it for a couple months. He eventually ran out of things to do, as he claimed, and returned to monophasic sleep.
Denser naps at night
Research
Up to date, there has only been one official study on Uberman sleep, which is motivated by its existence and creation from Puredoxyk and its widespread practice over the decades. In 2013, the research focused on the endocrine and cognitive effects of Uberman sleep. This study[2] lasted for 5 weeks. Unfortunately, according to the authors of the paper, no more information is available from the experiment beyond the abstract.
This study sheds some light on the vision of a long-term Uberman lifestyle as well as its implications on overall well-being of polyphasic sleepers. It is remarkable that most of the subjects quit the experiment because of social life rather than the grueling adaptation by week 3, and one subject did last until the end of the 5-week experiment. These participants were monitored 24h a day, and were woken up when needed to be.
None of these subjects were habitual nappers or sleep mutants, the remaining subject might have adapted to Uberman after 5 weeks, as his cognitive performance and cortisol secretion pattern became stable. At the same time, 5 weeks may not be enough for a successful Uberman adaptation. Even if it was a success, it took laboratory-controlled environment to get this far on Uberman - a regular adaptation with multiple alarms, no human assistance as mentioned before, will most definitely lead to failure.
Despite the seemingly positive news on this hostile schedule, it was discovered that growth hormone (GH) was greatly suppressed. Instead of being secreted in one large peak during monophasic sleep, it was now secreted after 6 naps in much smaller peaks. This might be because SWS was interrupted. This also explains why physical training would be ineffective on Uberman.
