Everyman 1, or E1, is part Everyman and part Biphasic, it trades one cycle from [[monophasic]] for a single nap in the day. Because of the sleep cut from the core, sleep deprivation will gradually build up, and enable sleepers to eventually fall asleep in the nap. This process is likely a lot easier than learning to nap on a non-reduced Biphasic schedule (i.e., [[BiphasicX|Biphasic-X]]), because there is more sleep pressure generated from a shortened nocturnal core sleep.

It was originally thought that the nap on E1 should primarily contain REM to ensure a successful adaptation. However, according to the Polyphasic Survey 2018<ref>https://polyphasic.net/wp-content/uploads/2019/03/Polysurvey-2018-results-and-analysis.pdf</ref>, only '''50% of adapted E1 sleepers managed to get REM in their nap'''. This shows that the afternoon nap is not guaranteed to deliver REM sleep. Based on the data above, it still seems possible to complete the adaptation to E1 with no REM in the nap. This is likely a result of those adaptees covering their REM need by their core, leaving their nap as just wakefulness sustainment.

The extended version is the usual recommendation for sleepers who are younger than 16 years old, or  older people who have a highly physically active lifestyle, a high sleep requirement and/or scheduling constraints (e.g, long wake gap from 9 AM to 5 PM). For a 9-hour monophasic sleeper, this variant offers a decent amount of sleep cut, requiring only one nap to make the schedule work. With a lot of sleep in stock, the extended version allows for more versatility in the placement of nap times. Because most, if not all of the vital sleep stages have been covered in the core, the nap mostly serves to give an alertness boost to improve learning and memory. The nap can then be placed in later hours of the day (e.g, 4-5:30 PM).

However, because of a high total sleep, it may take a long time to finally be able to fall asleep in the nap compared to standard E1. The adaptation to E1-extended may last just as long as the regular version, but with a much milder adaptation and possibly [[4-Stages_Adaptation_Model#Easier_adaptation|silent stage 3]], with no signs of severe sleep deprivation symptoms or crippled productivity as seen on other more reducing schedules that has been observed in successful adaptations. Picking this variant as a result may give the benefit of potentially maximizing daily performances (physical and cognitive) at work and/or school even when adapting.
