Is polyphasic sleep dangerous?

Polyphasic sleeping is unhealthy.

Polyphasic sleeping is dangerous.

You’re harming yourself when you’re sleeping like this.

Wait a second, where’s your evidence for this claim?


The idea behind this course is to examine several aspects; these can give insight into what it would take to show that polyphasic sleeping is dangerous. But first, an elaboration. The health-aspect of polyphasic sleep contains two questions;

  • Is polyphasic sleeping dangerous, and
  • Is polyphasic sleeping healthy, where the latter is much harder to show.

In reality, polyphasic sleeping may give some benefits, while also resulting in some negative aspects. Thus, the purpose of this course is to address the first question of “is polyphasic sleeping dangerous”.

First, a bit of background. Several people have claimed that polyphasic sleeping is dangerous without backing the statement up. The goal is to present the full picture here. This page will contain several sections.


Each section will structure as follows:

  • First, you will be presented with what topics to show that polyphasic sleep is dangerous.
  • Second, preliminary tests from the community thus far on these topics.
  • Third, we will examine the future of testing.
  • Fourth, clear questions polyphasic sleep debunkers would need to answer for their claims to bear any weight.

The goal is to give you a basic level of understanding so that you can learn what to investigate further yourself. If you are a skeptic looking to debunk polyphasic sleeping, this post will detail clear points for which you need to find evidence.

In scientific theories, there are always several different ways to discard them by proving them wrong. For example, the theory of evolution can be disproven by showing observations of supernatural or spontaneous creations of organisms. Similarly to this, there are ways to show that sleeping polyphasically is unhealthy. This is going to be a focal point of each section of this course.

Several of these sections will build around the question “are polyphasic sleepers actually sleep deprived“. There will also be several different perspectives to help you determine the answer. In these sections, peer-reviewed research articles and community evidence with external devices such as EEGs will accommodate this. Notably, it is necessary to account for an evidence hierarchy, where peer-reviewed research is “worth more” than non-peer-reviewed research, etc.
