Translations:Sevamayl/13/en

Sevamayl is regarded as an ultimate form of polyphasic sleep, allowing many waking extra hours, while also maximizing alertness, without having to stick to any strict sleep times. However, its difficulty lies in the length of time it takes for a successful adaptation, which can take several months to complete. Daily scheduling needs to be stable for the first two or so months, before Sevamayl can be attempted. Then, the adaptation to flexing naps and and changing nap count also takes another month or two, most of which would feel similar to Stage 4, where one feels mostly refreshed, but not quite. Risk of oversleep remains, even as natural wakes become frequent.
