Day 257 | Non-Continuous Dual Core 1

Core 1 | 11:00 PM – 2:30 AM

Core 2 | 6:00 AM – 7:30 AM

Nap 1 | 3:00 PM – 3:20 PM

I’m currently sleeping on the Dual Core 1 sleep schedule and loving it. I do think it’s my bodies most natural sleep schedule I’ve found so far.

The only times I feel tired are A) when it’s time for a nap/core and B) sometimes when waking up to my alarm if I haven’t been sleeping well or consistently. The rest of the time I have higher energy than I do on monophasic! I just used an exclamation mark at 4:03 AM so you know I’m full of energy!

Lately, I’ve been experimenting with being on Dual Core 1 and going off of it to monophasic when required for my social life. For example, the last time I went to monophasic was for a celebratory BBQ at my in-laws with friends and family. I knew I would be there socializing and lightly drinking from 11am until after dinner time. Instead of sneaking away to a bedroom or my car to take a 20 minute nap, I decided the night before to get a “good nights sleep” so I wouldn’t need to nap. When I go to monophasic for a day or two, I just sleep 7 to 8 hours at night and then I don’t need a nap. Boom! Magic.

I’m going rock climbing on Sunday and I need to be up and in the car by 6am. This doesn’t fit well with my normal second core between 6-7:30, so I’ll probably go to bed at 10 PM and wake up at 5:30 AM for the trip and be good to go all day.

Then, the next night, I just set my alarm for 2 AM and I’m right back on track with DC1.

I haven’t been able to find any research or even much anecdotal discussion of doing this. I believe the reason I’m able to transfer on/off fairly seemlessly is that I’m so adapted to polyphasic sleep. I don’t need to sleep deprive myself anymore to take full REM advantage of a nap time, my body is ready to soak up the useful sleep no matter what I slept like the night before. This lets me adjust on-the-fly to what sleep schedule is most effective for me at that point.


  1. I am slightly more sleepy both the first monophasic day and first DC1 day after a short term switch – but it isn’t drastic
  2. I wouldn’t ever recommend this as it is less ideal than maintaining a strict schedule, but I 100% recommend against it if you haven’t “mastered” a polyphasic sleep schedule and experimented with how you feel transitioning on/off it

Keep up the poly sleeping and I hope to see you more on this blog in the near future!

Day 164 | End of DC1 (for now)

Core 1 | 10:30 PM – 2:00 AM

Core 2 | 6:00 AM – 7:30 AM

Nap 1 | 2:15 PM – 2:35 PM

Even though I haven’t checked in on this blog in a little while, I’ve been really enjoying Dual Core 1 polyphasic sleep! This was the first time on polyphasic sleep that I really found a rhythm that wasn’t difficult to keep up. On Everyman, it was really hard to get out of bed about half the time (the other half I jumped right up). But on DC1 I’d say it was only really hard to get up about 10-15% of the time. Typically, these difficulties were tied to my inconsistency, like a really late nap or having a few drinks before bed.

If you’re enjoying it so much, why are you stopping DC1 you ask?

A few reasons:

  • I have a week long trip to Yellowstone coming up in 1 month that I’m really excited for! I’ve learned it’s hard to keep polyphasic on vacations spent with a lot of other people…
  • I’m picking up my Brazilian Jiu Jitsu training and I want to gain about 5 pounds of muscle & boost my strength before I go on the trip. It’s hard to lift heavy and gain muscle on polyphasic
  • Honestly, after almost 6 months of sleeping polyphasic, I’m tired of napping and always being conscious of time and when my next nap needs to be. I just want a break.

I’ll circle back in a couple weeks of sleeping monophasic again and report back! I think in a couple months I’ll jump back on the polyphasic train and I’d still love to create the polyphasic adaptation guide! I wish I had one when I was first starting…


Thanks for always following along and being supportive!

Day 128 | Afternoon Nap Shifting

Core 1 | 10:45 PM – 2:15 AM

Core 2 | 5:30 AM – 7:00 AM

Nap 1 | 3:40 PM – 4:00 PM

I’ve been struggling with two things on the new schedule (it’s only been 5 days, so I know a few struggles are to be expected). The first is going to bed early and consistent. I had a filled and long weekend and I always struggle saying no to social invites in preference of sleep. That’s a flaw of mine when it comes to polyphasic sleep.

The second struggle I didn’t expect as much. That is finding a good time in my schedule for my afternoon nap. I really liked on my last everyman round having a noon nap and a 5 pm nap. These signified time to each lunch and time “end my work day” or at least take a break before doing some moonlighting.

Now, with one less nap, it should come around 6-7 hours after I wake up from my second core, which would put the nap around 1:30 – 2:30 PM. That’s an awkward time for me. Having naps in transitional periods is really nice for me, and that time just isn’t working out.

I think the best approach I can take to gain some stability in this nap time is to adjust my overall schedule to make this time a transition. For example, I can each basically two lunches, one small one at around 11 AM when I typically first get hungry after breakfast and then have another lunch after I wake up from my nap around 2 pm… I’m not sure this is the best schedule shift, but I’m going to make some schedule changes for sure.

Day 126 | Napping Well and Feeling Pretty Good

Day 124

Core 1 | 11:30 PM – 3:00 AM

Core 2 | 6:30 AM – 8:00 AM

Nap 2 | 2:30 PM – 2:50 PM

Overall, my third day on DC1 went well. I accidentally got somewhat drunk last night, which doesn’t ever help adaptation and is not a good way to go… (Do as I say, not as I do…)

I still was able to wake up to my first alarm and the only abnormal thing is how much water and snacks I had when I got up at 3 AM feeling pretty hungover, but still a little buzzed.

My second core and my afternoon nap both went great! I slept the entire time and woke up without too much trouble to my first alarm.

Also, I did a Brazilian Jui Jitsu class in the afternoon which kicked my ass. I’m excited to start testing polyphasic while exercising fairly hard again as I’m getting more healthy from a nagging ankle injury.

Day 124 & 125 | Beginning of Dual Core 1

Day 124

Core 1 | 11:00 PM – 2:30 AM

Core 2 | 6:00 AM – 7:30 AM

Nap 2 | 1:30 PM – 1:50 PM

Day 125

Core 1 | 11:30 PM – 3:00 AM

Core 2 | 6:10 AM – 7:40 AM

Nap 2 | 3:00 PM – 3:20 PM

My first two days of DC1 have gone much better than I expected honestly. The first night I woke up 5 minutes before my first alarm from my 1st core and the second night I woke up easily in my first pebble alarm. Both days I had plenty of energy in my night work session and got a lot accomplished (especially important while we’re launching our new app :)

My first day I had trouble sleeping in both my second core (maybe got 30 minutes total) and in my afternoon nap (maybe got 5 minutes if I’m lucky). Day 2 was definitely better. My second core went great and my afternoon nap I still only slept about 5 minutes. The few big contributors to not getting good second core and nap sleeps I think are: 1) being overly excited about starting DC1 and being polyphasic again (I’m weird, I know), 2) being busy at work with a racing mind, and 3) being fully rested going into the adaptation attempt.

I’m guessing I’ll be sleeping good in my second core from here on out and after a few days my afternoon nap will become more solid as I get more tired and need it.

More details coming soon on my schedule and napping strategy during adaptation.
