From Polyphasic Sleep

Contents

Introduction

This wiki is about polyphasic sleep schedules in human beings. For purposes of discussion here[1], being on a polyphasic sleep schedule means

  • distributing sleep over a 24-hour cycle
  • in at least two (but usually more) regularly scheduled blocks,
  • with one or more of the blocks being naps, and
  • staying on this schedule for long enough that sleep deprivation (if any) seems negligible.

In the ultra-short polyphasic sleep schedules, all of the sleep periods are naps. Some research (and quite a few anecdotal reports) suggest that, after adaptation, the sum of all parts can be less than that of the night sleep (or, in polyphaser parlance, "core sleep") previously needed. Unsurprisingly, gaining more free time is the motivation most often mentioned by those who attempt polyphasic schedules as a lifestyle choice.

According to the above definition, a sleep schedule comprising of a night sleep and one nap would also be called polyphasic. However, the main focus here is on schedules with considerably shortened core sleep (if any) and three or more naps.

Better-known sleep schedules

These schedules are increasingly gainful but also increasingly hard to adapt to and increasingly strict, regarding the sleeping times. In particular, it's not clear that anyone (even Fuller) has ever succeeded with Dymaxion, at least not without first fully adjusting to a very stringent polyphasic schedule like Uberman.

Notes

  1. Claudio Stampi, writing in Why We Nap (p.3), uses a tighter definition of polyphasic sleep:
    Phasic behavior is divided into two major categories: polyphasic and monophasic. Each major category is divided into three subgroups, according to whether the behavior under study strictly respects definitions of one or the other category. Hence a pure polyphasic behavior occurs when episodes of sleep and activity are evenly distributed throughout the 24 hr (see Table 1.1). Quasi-polyphasic behavior applies when sleep-wake episodes are not evenly distributed throughout the 24 hr (e.g., when there is a preference for diurnal activity and nocturnal rest, or vice versa). Behaviors are considered polyphasic (pure or quasi-) provided that less than 50% of total sleep time is taken continuously. If more than 50% of total sleep time is taken as one continuous episode, this will be included in the monophasic category. Analogously, pure monophasic behavior occurs when all sleep is taken in the form of a single daily episode. Quasi-monophasic applies to when more than 50% of sleep is taken in one episode, and the remaining amounts in one or more episodes. Finally, there is an intermediate category, which can be termed indifferently either semipolyphasic or semimonophasic. This occurs when exactly 50% of sleep is taken as a single episode, and the remaining portion in one or more episodes
