Mechanism
After adapting to a rigid Everyman schedule, the brain slowly becomes accustomed to a lower sleep total and a napping habit. It then becomes possible to start flexing the naps, with a only a minor decrease in quality. Still, as much of the REM is accounted for by the core on schedules like E3-extended, the main purpose of the naps is to alleviate Sleep pressure and boost alertness. It is also possible to use pronaps to fulfill the REM need, reducing the need for naps later in the day.
