However, what is for sure is that it provides an opportunity for improved productivity provided the enhanced number one puts to work.

This study established that unlike a monophasic sleep schedule, the polyphasic one makes folks experience sleepiness during the day as well as poor sleep quality in the long term.

Another study seems to claim that a monophasic sleep schedule can lead to accumulated sleep debt especially in folks involved in jobs that require continuous performance such as those in defense missions, space missions, rescue operations, and health care.

It’ll turn out to be magical for sure.

Here are some reasons to practice polyphasic sleep;

More free time

With the additional hours, you’ll manage to strike a healthy work-life balance.

The focus of polyphasic sleep is quality rather than quantity. When you skip the initial sleep stages, you might spend ample time in the slow-wave and REM sleep phases. This results in enhanced memory and creativity.

Incredible for non-conventional schedules

This type of sleep schedule is efficient for those that can’t clock 7 – 9 hours every night. For instance, folks working overnight shifts or those in the military find polyphasic sleep more manageable than the other types.

Improved creativity

As aforementioned, this schedule results in higher levels of creativity. Polyphasic sleepers usually enter the REM sleep stage faster which is a stage associated with creativity. Because they do not enter the lighter stages of sleep, these types of sleepers tend to spend vast time in the REM sleep stage.

Downsides

Many people are conventional sleepers. They sleep at night during the normal 7 – 9 hours. Polyphasic sleepers, most of the time grapple with social obligations as most of the time their family or friends are unavailable. Sleep schedules that need naps through the day are somewhat challenging to stick to especially for those that work 9 – 5 jobs.

Famous Polyphasic Sleepers

Part of the reason for the growing popularity of the polyphasic sleep schedule has to do with its association with prolific politicians, inventors, and artists. Leonardo da Vinci is perhaps the most popular polyphasic sleeper. A renowned inventor and painter, he allegedly slept for around twenty minutes, several times in a day.

Another famous polyphasic sleeper is R. Buckminster Fuller, an inventor, and architect. Being a vocal supporter of polyphasic sleep schedule, rumor has it that he’s responsible for developing the Dymaxion sleep cycle. Mr. Fuller was a strict adherent of this schedule for around two years. He quit following pressure from both his wife and business partners that insisted on the conventional sleep cycle.

Winston Churchill was not only a committed napper but also a devoted night owl. He slept in the wee morning hours (3 – 8 am) coupled with 2-hour naps in the afternoon daily. According to Churchill, this schedule was magical in enabling him to accomplish up to a day and a half’s worth of work daily.
