Everyman 2, or E2, is the basic and most simple Everyman schedule in the Everyman polyphasic series. It consists of '''2 naps''' and a core sleep of 4.5h (3 full cycles) by default.<ref>[https://www.polyphasic.net/schedules/everyman/ polyphasic.net]. Retrieved 25-11-2020.</ref> It was also part of the Formula that details the Everyman schedules with the number of naps depending on the duration of the core sleep. However, it was '''not the very first and original Everyman schedule'''. Along with E4 and E5, it was more of an afterthought schedule, after Puredoxyk successfully adapted to E3 and coined it the epitome of Everyman sleep.

Everyman 2, or E2, is a highly popular schedule in the Everyman line. It consists of 2 naps and a core sleep of 4.5h (3 full cycles) by default.<ref>[https://www.polyphasic.net/schedules/everyman/ polyphasic.net]. Retrieved 25-11-2020.</ref>

The naming of the Everyman schedules, starting from E2, has been changed over the years for more consistency with all other polyphasic schedules. It used to be called E4.5, to represent the core duration, however over the years it has been changed to E2, to represent the number of naps. In the most recent years, it has garnered a massive amount of attempts, and is '''one of the most popular polyphasic schedules''' offered in this sleep regime.  

E2 was given by the [[Ubersleep]] Formula that details the Everyman schedules with the number of naps depending on the duration of the core sleep. Along with E4 and E5, it was presented a version of Everyman that is closer to mono than [[E3]] is, after Puredoxyk successfully adapted to E3 and coined it the epitome of Everyman sleep.

As the next upgrade from E1, E2 removes a full cycle from the core, and adds another nap. The premise behind this mechanics, as explained by Puredoxyk, is that '''a 20m nap can replace a 90m cycle of sleep because of the REM amount that each nap can provide'''. The core sleep of E2 now has 3 uninterrupted full cycles of 90m each. Because of the shortened duration compared to the default E1 core, the first nap is also moved to around the sunrise hours (however this is not the only way to schedule E2), and another nap is often scheduled around afternoon hours. This is because the shorter core sleep does not allow for only 1 nap to sustain alertness for the whole day, so another nap becomes necessary to balance the much longer wake gap in the day, and creates an ideal homeostatic distance between each sleep so that sleepers are not forced to stay awake for too long.  

As the next step after E1, E2 removes one more cycle from the core, and adds another nap. The premise behind this mechanics, as explained by Puredoxyk, is that '''one 20m nap can replace one 90m cycle of sleep because of the REM amount that each nap can provide'''. The core sleep of E2 has 3 full cycles of 90m each. By default, the first nap is scheduled at around the sunrise hours, and another nap is often scheduled around afternoon hours. As the core is shorter, another nap becomes necessary to divide the much longer wake gap in the day, and creates an ideal homeostatic distance between each sleep so that sleepers are not forced to stay awake for too long.  

There are a couple ways to schedule E2, but the general idea is to make use of the sleep distribution that often follows the body's natural rhythm and to sensibly maintain other work/school schedules and commitments. It is commonly acknowledged that '''daytime hours sustain alertness better than nighttime hours''' as per the transition from old-school monophasic sleep (assuming a normal nocturnal monophasic pattern). This means that the wake gap between the first nap and the end of the core is often the shortest, while it is easier and more manageable to stay awake for a lot longer from the second nap to the beginning of the core, taking advantage of the afternoon hours. For this reason, ideally the first nap can be anywhere from '''4-6h''' after the core's end, and the last nap can have an '''8-9h wake gap''' until the core.  

There are a couple ways to schedule E2, but the general idea is to follow the body's natural rhythm while sensibly maintaining other work/school schedules and commitments. Usually, it is easier to stay alert in the day than in the night during the transition from a typical monophasic schedule. This means that the wake gap between the first nap and the end of the core should be the shortest, while the gap before core can be longer because of higher alertness during late afternoon hours. For this reason, ideally the first nap can be anywhere from '''3.5-5.5h''' after the core's end, and the last nap can have an '''8-9h wake gap''' until the core.  

Furthermore, the 4.5hr core allows '''plenty of time for all SWS needs to be met even during adaptation''', since even monophasic sleepers typically complete all SWS by the middle of the night, through their 3rd sleep cycle. This assurance allows for much greater flexibility in core placement with the best placement around around midnight. Some core time in the graveyard hours (midnight through 8AM) is recommended for a good balance of '''REM pressure''' (closer to 6AM when REM peak starts) vs '''SWS pressure''' (peak at 9PM – midnight). Since E2 only has 2 naps (providing 10-15m REM each), at least 60m of REM should be completed in the 2nd and 3rd cycle once adapted. It is recommended for the first nap to be placed squarely in the REM peak of 6-9AM, virtually guaranteeing quality REM sleep for the bulk of the nap. However, as of late it has been discovered that the second nap on E2 may '''only give light sleep''' rather than REM sleep, if this nap is late into the afternoon (e.g, 4 PM onward). Most of the adapted cases to a late second nap likely show that their REM baseline on monophasic sleep is lower than or very reduced compared to the usual 90m benchmark. 

Furthermore, the 4.5hr core allows '''all SWS needs to be met even during adaptation''', since even monophasic sleepers typically gain all the required SWS by the middle of the night, through their 3rd sleep cycle. This assurance allows greater flexibility in core placement with the best placement being around around midnight. A core during the graveyard hours (midnight through 8AM) is recommended for a good balance of REM and SWS pressures. It is recommended for the first nap to be placed squarely in the REM peak of 6-9AM, virtually guaranteeing quality REM sleep for the bulk of the nap. However, more recently it has been discovered that the second nap on E2 may only contain light sleep rather than REM sleep, if this nap is late into the afternoon (e.g, 4 PM onward).
