The community has decided to start conducting experiments themselves because of the lack of peer-reviewed research about polyphasic sleep. Small-scale tests with electroencephalograms were started during 2017, and large-scale tests were developed throughout 2018. The gathering of information is still continuing, and the purpose of this page is to share the findings, as well as inform people of what tests are currently being conducted and which ones are planned for the future.

Polyphasic survey

The current polyphasic survey and the past polyphasic survey analyses are listed here. If you want to complete the most recent polyphasic survey yourself you can do so by following its link.

The sleep deprivation of polyphasic sleepers after adaptation

The point of this group of experiments is to determine whether polyphasic sleepers who claim to be adapted actually get the quality sleep they need, and if they show any symptoms of sleep deprivation.

Amounts of REM sleep and SWS (being tested)

Hormonal levels after adaptation (being developed)

Sleep onset outside of the schedule (being developed)


Experiments concerning sleep in general are listed here.

Flexing sleep (being tested)

Cycle compression (being tested)

Statistically likely REM period (being tested)


There is a lot of research regarding how different substances affect sleep, however there is no peer-reviewed research on the effects of these substances on polyphasic sleep schedules. What is tested in these experiments is especially the effects the substances can have on SOREM naps, sleep architecture, total REM sleep and SWS durations, and so on.

Caffeine (being tested)

Nicotine (being tested)

Alcohol (being tested)

Cannabis (being developed)

Fat (being tested)

Vitamin C (being tested)

Vitamin D (being tested)


Tests made regarding lifestyle and activities go here.

Meditation (being tested)

White noise (being tested)

Binaural beats (being tested)

Dark period (being tested)
