Translations:Unstable adaptation/3/en

It is usually very difficult to adapt to schedules with a low total sleep time, since much more sleep compression should occur, leaving significantly much less light sleep. This makes the sleep schedule much less flexible and generally unstable, because any event or substance which temporarily increases the sleep needed to recover can easily compromise adapted state. This is likely the main reason why long term polyphasic sleepers more often are those who stay on a schedule which reduces little-to-no sleep, while most nap-only adaptations are shorter.
