No. No. No.[edit]

This is NOT how sleep works. Sure, a standard sleep cycle is around 90 minutes in length. Other than that, I don't think anything in this article is at all accurate.

The source it cites is absolutely ridiculous. The author states that REM sleep is the most important part of sleep. Since when? Information that I've encountered that has examined the effects of selective sleep stage deprivation has demonstrated that being deprived of slow wave sleep tends to lead to far worse effects than REM sleep deprivation. Furthermore, sleeping in a bi-phasic cycle seems unlikely to maximize REM sleep at all, given that early in the sleep cycle, slow wave sleep is predominant. In fact, it is common for there to be no REM sleep occurring during the first sleep cycle of a night. The theory behind this is that the homeostatic need for sleep is paid off more quickly with slow wave sleep.

When I have time, I'll have to rewrite this article to reflect what the real research has indicated, rather than citing some layperson who tried something.

Maybe these are not facts as you say. But there have been no official studies done on biphasic sleeping. Whether you consider these facts or not, these are the principals that biphasic sleeping in centered around. The actual results are that your body adjusts to the new sleeping pattern and thus you do fall into REM sleep in the first sleep cycle.—The preceding unsigned comment was added by 216.12.38.216 (talk • contribs).

You will not find a more credible source than the 'layperson' who tried something. That is all that exists on this matter. Better a layperson who tried something as the source than an untrained doctor who didn't.

Redirect?[edit]

The article is a stub, and the sources are blogs. I would suggest redirecting this entry to the Polyphasic Sleep
