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!
