== Origin ==

SPAMAYL is an abbreviation of “'''Sleep Polyphasically As Much As You Like'''”, one of the 4 "-AMAYL" polyphasic schedules. Originally proposed by '''Rasmus''', who reportedly stayed on the schedule for 1.5 years, SPAMAYL is intended to be the first "-AMAYL" polyphasic schedule with hyper flexibility in sleep times, following the body's need for rest to place the naps accordingly. The original design of the schedule exclusively uses 20 m naps. Recently, it is also sometimes referred to as U7 or U8 ([[Uberman]] with 7 or 8 [[naps]]).

The schedule is based on the entrainment of 20 m naps, napping for 20 m when one is tired enough. Since there are no core sleeps, all necessary [[wikipedia:Slow-wave_sleep|SWS]] and [[wikipedia:Rapid_eye_movement_sleep|REM]] must come from the naps. Like with Uberman and [[Dymaxion]], a SWS nap can be experienced during the REM peak, and REM nap during SWS peak. Sleep pressure is usually huge since SWS and REM have to be repartitioned into all naps, and one cannot predict which sleep type each nap can have, due to the varied number of naps each day. However, SPAMAYL is '''less hostile''' than Uberman and Dymaxion, since it can allow more than 6 or 4 naps respectively, and the extra sleep from the extra naps will help accommodate sleep need more easily, allowing for extra REM and SWS gain. However, because the naps are being moved they will contain a lower amount of SWS or REM than the naps of strict nap-only schedules, thus requiring more naps to give the same total SWS and REM sleep. It is likely that only adults with genetically reduced sleep needs will be able to accomplish this type of sleeping pattern, due to the inefficiencies of inconsistent sleep times and the very low sleep total. Experienced nappers can also achieve a fast onset of REM or SWS in their nap, with precise timing of sleep.
