[[Puredoxyk]] named Uberman as a less extreme version of [[Uberman]]. Everyman (what is now the Everyman 3 variant) was proposed as a way to adapt to less sleep more easily, while being more in sync with normal daily life without the need for extreme rigidity in naps in Uberman.

By 2008, it had become popular as the “fallback” for failed Uberman attempts. It was inspired by the first wave of Uberman attempts after Puredoxyk in the early 2000s, and then again starting around 2007 by personal growth blogger [[Steve Pavlina]]'s grueling [https://www.stevepavlina.com/blog/2005/10/polyphasic-sleep/ adaptation log] for Uberman. The repeated experience of Uberman attempters was to crash uncontrollably for several hours, every couple days or so. It made sense, then, to schedule those crashes into a 3-hour core.

There has been changes in E3's scheduling over years. Puredoxyk's original E3 has the core starting near midnight, which is now considered a [[late core]] for E3, and is suboptimal for gaining [[Wikipedia:Slow-wave_sleep|SWS]]. Currently, the default variant has the core occupy most, if not all of the SWS peak hours.

E3 has been one of the most popular schedules because of its large sleep reduction as well as its feasibility in people's daily lives. Despite the relatively low success rate, its popularity never subsided.

Following from E2, E3 further removes a full cycle from the core sleep and adds another 20m nap. The core sleep on E3, lasting for only ~3-3.5h (depending on scheduling), accounts for only 2 full sleep cycles.  Four hours total daily sleep is considered the minimum to contain a sustainable 90m SWS, 90m [[wikipedia:Rapid_eye_movement_sleep|REM]], and transitional light sleep. Similar to other schedules, 20m naps are preferred over 30m naps or longer naps because it prevents [[wikipedia:SWS|SWS]] wakes from the start of adaptation, and generally easier to handle.
