Sleep, one of the most sought after commodity for many of us. It’s not that we don’t want to sleep, sometimes it’s just our lifestyle that limits our snooze time. And most of us have experienced what happens when our sleep gets thrown out of a routine. It take FOREVER to get back into the original schedule. For us nine-to-fivers, a late night out on Saturday means sleeping in on Sunday, which means not falling asleep til the late hours Sunday night. This in turns leads to coffee or tea or both being our breakfast Monday morning.

The later than usual bedtimes continues throughout the week because of work, family life, or other obligations we may have. If we’re lucky (or disciplined enough), we get to go to bed early to catch up during the week. Most of us typically look forward to the weekend to pay off that sleep debt. But more likely than not, the vicious cycle of late to bed, early to rise comes back to haunt us. If this is a normal part of your life, do know that it does not have to be. So how can we break out of this cycle? What about my responsibilities, I can’t neglect my kids/job/parents, etc? Is there anything I can do that will give me more time AND is sustainable?

Enter Polyphasic Sleep.

What Is Polyphasic Sleeping?

Simply put, polyphasic sleeping is sleeping in different time blocks throughout the day. These sleep sessions are usually separated by at least 2 hours of wakefulness. The more common sleeping schedules involves a “core” sleep, which is the longest sleep session within a 24 hour period, and nap(s) that are shorter in duration.

For those of us that sleep throughout the night and wake in the morning, we are on a monophasic sleep schedule. This means we have one sleep session for every 24 hour period. Some of us may take a nap or two throughout our day. If those naps are spaced at least 2 hours apart from each other and the core sleep, you are technically on a polyphasic sleep schedule known as the siesta (if it’s one nap only, multiple naps will be explained below).

Segmented Sleep

Another polyphasic sleep schedule is the segmented sleep. This involves two core sleep sessions with one nap. So you may sleep from 8 pm to 11:30 pm, remain awake until 2 am, then sleep from 2 am to 5:30 am. One of the core sle

ep sessions could be shortened and the time can be made up with a nap.

This schedule is probably the easiest to adapt to for those wanting to try out a polyphasic sleep schedule besides the siesta. Matter of fact, my dad was sleeping like this naturally for a period of a few months when he was working very hard (although I’m not sure if he took naps). He’d come home around 7 pm and be asleep by 8:30 pm, then wake at 12 am or so and wouldn’t go back to bed until 2 or 3 am, just to wake a few hours later for the morning coffee.

Dual Core Sleep

By definition, the dual core schedule involves a total of only 5 hours and 20 minutes of sleep per 24 hour period. The core sleep sessions can be evenly split or one at 3.5 hours with the other at 1.5 hours. The core sleep sessions are separated by 4 to 6 hours of wake time.

A nap of 20 minutes is included somewhere throughout the day, preferably in the middle of your waking time. This leaves evenly split waking times between your first core sleep to your nap and your nap to your second core sleep.

There are more variations to this that reduces core sleep time and adding naps to make up for it. A lot more detailed information can be found using a simple google search, but a really good resource for this topic can be found here.

Everyman (E2, E3, and E4)

This is where polyphasic sleep starts getting interesting. The Everyman schedule has many variations, hence the E2, E3, and E4. The number represents the number of naps involved with each schedule. As you may have guessed, the more naps there are, the shorter in duration the core sleep is.time-is-money-1339781_640

The E2 has a 5 hour core sleep with two 20 minute naps. Although it has more total sleep time than the dual core schedule, some may feel that the dual core feels more natural that this schedule. The probable reasons will be explained in a later section.

The E3 has a 3.5 hour core sleep with three 20 minute naps. The naps do not necessarily have to be spaced to allow for even duration of wake times. But they do have to be placed strategically, due to how our circadian rhythm operates. This will also be explained in more detail in a later section.

The E4 has a a 2 to 2.5 hour core sleep session with four 20 minutes naps. Since it has one more nap than E3 and less time for core sleep, strategic placement of nap times is even more crucial for the success of this schedule.

Uberman and Dymaxion

I’ve decided to keep these two schedules within the same section because they are both equally extreme in my opinion. These two schedules allow for only 2 hours of total sleep time in a 24 hour period. If we are to follow either one of these schedules to the “T” indefinitely, we will be awake for 92% of the rest of our lives.

Uberman consists of a 20 minute nap every 4 hours, resulting in 6 naps. Dymaxion was coined by Buckminster Fuller, who slept for 30 minutes every 6 hours, resulting in 4 nap. You can read more about these two schedules with the link I previously posted.sleeping-1051509_640

Strategic Placement of Naps and Core Sleep

As you may have already noticed, the total sleep time for most of these schedules are the less than the commonly recommended 7-8 hours per every 24 hour period. It is for this reason that most people are on a polyphasic sleep schedule. While some may be following one of the schedules due to medical reasons, most do it for the extra wake time these schedules allow.

Obviously, wake time is useless if we’re constantly in zombie mode. Therefore, these schedules are meant to allow us to function as if we got the recommended hours of sleep. But for them to work as intended, strict adherence to and strategic planning of the core sleep and naps are critical.

Circadian Rhythm

Each of us have an internal natural biological clock. This clock tells our body to perform certain function in response to the different time of day. For example, melatonin is release as our body perceive that night is approaching, giving us the feeling of drowsiness. Or when our body core temperature reaches its lowest about 2 hours before our wake time to allow for the subsequent rise in core temperature, which some scientist believe is vital in waking us up.

Now that we know our body does its own thing on its own schedule, it’s important to know when to have our core sleep and naps so that our sleep quality is maximized. If we’re going to get away with less hours, we need to beef up our sleep quality to make up for that.stick-309861_640

The two most important aspects of circadian rhythm to remember is what times our body is under rapid eye movement (REM) pressure and when it’s under slow wave sleep (SWS) pressure. Sleeping around the times when our body is under either one of the pressures will result in sleep that corresponds to that state.

Some of us may already know that REM phase of sleep is when we dream and when our mental engine is restored. SWS is when our physical body undergoes restoration, with the release of different hormones that promotes the repair of our muscles, bones, organs, etc.

Humans as a species experience the most SWS pressure from the early morning until midday. The actual time when REM pressure starts is around 3 am, and it progressively gets more intense as time passes until noon. SWS pressure is felt mostly in the evenings until midnight, with an actual start time around 3 pm and progresses in intensity much like REM pressure.

So What Does This Mean?

This means that depending on our goals and what we’ve been doing throughout the day, we may place more emphasis on SWS than REM ssleep. If that’s the case, depending on the schedule we’re doing, we can place the core sleep in the early evening with the wake time around midnight.

Typically, with a schedule like Everyman, the core sleep is from the early evening until around midnight. This promotes the healing of our physical bodies. Then the subsequent naps are takpainting-1077863_640en between 3 am to 12 pm to promote REM sleep, which restores our brain and mental faculties.

The Specific Schedule I’m Attempting

I am personally going to be attempting the Everyman E3 schedule again some time soon. Yes, again as in I’ve tried it once and failed miserably, which I’ll explain later. And also yes, some time soon as in I’m planning on it and will need to block out a few weeks for the adaptation period.

I will be sure to keep you guys updated on my progress once it starts.

Wow, this article is much longer than I had anticipated. It seems there are still unanswered questions about this topic. Not to overwhelm you guys, I will address some of these points in Part 2 of this article coming out next week.

  • What Other Benefits are there to Polyphasic Sleeping?
  • Isn’t sleeping less than 7-8 hours harmful?
  • How do I start polyphasic sleeping? Is a transition period necessary?
  • How do I tell if it’s right for me?
  • And of course, how did I fail on my first attempt at the Everyman E3 schedule?

Stay healthy,

I've just started getting serious about health and fitness around 2014. Since then I've learned the insider info on how to optimize athletic performance and healthy living through both nutrition and proper training. The most important thing I've discovered however, is the connection between the mindset of those that excel in athletics, and those that succeed in their life pursuits. I've spent the last couple years observing and drawing these connections and similarities, finally created a platform to share with you all what I've found, and how to apply them in your own life to get similar results.

  1. Wow. Very informative article on polyphasic sleep. I never thought about trying it. I definitely don’t usually sleep through an entire night, so I wonder if it would be for me. Good luck with your attempt at the Everyman E3 schedule. I’ll be interested to find out how it works out for you. I was wondering if you knew what would happen to your melatonin release once your schedule is changed? Since it works based on your circadian rhythm, I wonder if the hormone release changes as your rhythm changes. Is that what you’re actually doing? Changing your circadian rhythm?

    1. Pete,

      Assuming that you don’t have any sleep related medical conditions, not sleeping thru the entire night is normal for some of us. I will be keeping you guys updated with my E3 attempts. Just check back on my training updates periodically.

      As far as melatonin release, it is in response to the perception of night time. So with the E3 schedule, I’ll still be going to sleep around 8-9 pm, which coincides with my current sleep schedule. So my melatonin release will still be the same as long as I stay away from the bright light spectrum before going to bed.

      I am changing the hormone release somewhat because for monophasic sleepers, growth hormone releases during SWS phases around midnight to 3 am. Since I will be awake at that time, hormone release occurs during other phases of SWS for me.


  2. Very interesting subject. I have never thought of Polyphasic Sleep actually I have never even heard of it.
    Your website gave information that I maybe able to use in my own life.
    I don’t sleep well at night and wake up tired all the time I may try this just to see if it helps.
    Your sites layout is easy to follow and interesting. I hope to see more from you. I loved the graphics and pictures they went well with the overall theme of you website.

  3. Thanks for your article on Polyphasic sleeping. You have rightly mentioned in your article the need of sleep and I fully believe that a lot of the population today are sleep deprived. I’ve never heard of this sleep method before. I must say I’m an 8-9 hour sleeper at night. I’ll be interested to see how you go with your trial. All the best!

    1. Kym,

      It is a definite problem with the general population today. A lot of work related and vehicle injuries and fatalities are associated with fatigue and lack of sleep. I’m glad you see the importance of sleep. That’s great you’re able to get your full 8-9 hours, I know how refreshing it is to wake up after a great sleep. I will be keeping everyone updated once I start.


  4. Sleep can be a highly sout after thing, especially for people like me who routinely go through bouts of insomnia. And if our sleep cycle gets interrupted, we get completely thrown off balance. We may take melatonin or over the counter sleeping pills to get us back in sync, but if that doesn’t work then we head to the doc. And of course those who work regular day jobs, then go party on the weekends spend our Saturday and Sunday mornings sleeping in. If we get lucky we may go to bed early, but it’s usually the weekend where we rely on getting caught up on our sleep.

    So what can you do instead? There is this thing called polyphasic sleeping. It’s where you sleep in different time blocks throughout the day. So instead of having a core sleeping time, you would sleep say from 8pm to 12 am then be up for two to three hours , then sleep from say 3am to 6:30am. Then there are naps involved at 20 mins. Depending on how much time you’ve slept during the night you would have either 2, 3, or 4 20 minute naps throughout the day. But that would also depend on your job and what they allow. I would probably lean more toward more sleep at night and 1 nap during the day taking half my lunch period. However, in order for this to work there must be a strict adherence to the schedule, and it will take some getting used to.

    1. Nice summary of the article! Hahaha.

      I think if you plan to sleep once at night and have just 1 nap, it shouldn’t be too hard to adapt to if you’re transitioning from pure monophasic sleeping.


  5. Very interesting article! I had done some research on sleep and studied it in school, but never heard of this, so I found it quite fascinating! I was told in school that humans are actually designed to take a nap in the afternoon. Another interesting trivia – I remember reading years ago an interview with George Burns and they asked him what his secret was to living to such an old age and he said he took naps every day! Thanks for sharing! Great article!

    1. Debbie,

      Thank you for your comment! I also believe that napping is an essential part of sleep. It has worked for me at least and I hear positive experiences from others as well. Be sure to check out Part 2, where I explain the finer points of this concept. Thank you for the info!


  6. What a surprisingly interesting article! I have never heard of this style of sleeping and scheduling rest. I am at a point where my business and workout schedule takes up a LARGE amount of the day so maybe I need a different sleep schedule….anyways thanks for the great info!
