Hack Your Brain with Polyphasic Sleep

This video chronicles the speaker's personal experiment with polyphasic sleep, a largely untested hypothesis that reducing total sleep is possible by napping more often. After rejecting the brutal Uberman schedule—six 20-minute naps totaling just two hours a day—he chose the more manageable Everyman 2 schedule during the unique opportunity of the COVID-19 lockdown. Despite a challenging adaptation period of about two weeks, he reached roughly 90% adaptation while managing work and naps. Notably, the experiment cured his long-standing insomnia, but as a trade-off he became very tired by late evening. His key advice is to experiment quietly, ignore critics, start on a weekend, and use blackout curtains, ultimately encouraging viewers to test it safely for themselves.

• ▶ 0:42 Polyphasic sleep is a "largely untested hypothesis": sleeping more often during a 24-hour cycle reduces total sleep needed, supported by anecdotal examples like sailors, military watch, and parents of newborns [0:42–0:58].
• ▶ 1:21 The Uberman schedule is "as simple as it is brutal": six 20-minute naps every four hours, totaling just two hours of sleep per day, based on the theory that only REM sleep is essential if the brain can drop directly into it [1:21–2:18].
• ▶ 2:29 The 2007 attempt failed because of a brutal adaptation period — you can't nap at first and become sleep-deprived for about two weeks — plus society's rigid nighttime-sleep structure, which eventually pushed both Tris and Buckminster Fuller back to monophasic sleep [2:29–2:56].
• ▶ 3:02 Tris describes his poor sleep history: a lifelong need for lots of sleep, being a light sleeper, and developing mild insomnia in 2017 that made it take up to three hours to fall asleep.
• ▶ 4:00 The first COVID-19 lockdown created a rare opportunity: working from home, mostly digital socializing, and a four-day long weekend with no webcam obligations meant "the stars had aligned" to try polyphasic sleep.
• ▶ 4:31 He rejected Uberman again because polyphasic.net rated it "very hard" with a zero percent success rate, and instead chose the more approachable Everyman schedule, specifically resolving to try E2.
• ▶ 5:34 The first 24 hours of a polyphasic sleep experiment feel great because sleep debt hasn't caught up yet, making staying up all night feel meaningful rather than draining.
• ▶ 5:59 Everyman 2 was much easier than Uberman, but early days still involved tiredness and lying down was risky; by the fourth day back at work, the transition to five hours of sleep per 24 hours was basically complete.
• ▶ 7:07 The experiment began in April 2020 by waking at 03:00 cold turkey with minimal prep; playing low-effort video games like Fallout helped stay awake, and the two naps (07:00 and 13:00) fit flexibly into the workday.
• ▶ 8:05 By the two-week mark, the speaker felt about 90% adapted to the polyphasic schedule, even despite missing naps, sickness, and criticism from others.
• ▶ 8:25 The experiment cured the speaker’s long-standing insomnia, but as a trade-off they became very tired by late evening, falling asleep after 21:30 and ready to "drop" by 22:00.
• ▶ 9:15 Key advice: experiment quietly, tell only close people, and ignore critics—if it's safe enough, give it a go and find out for yourself. Also start on a weekend, use blackout curtains, and eat meals after naps to help adaptation.
