My polyphasic sleep pattern – aka scientific guessing

First, a bit of history. I switched to polyphasic sleep at the beginning of the year and kept it up for about 4 months or so. I started out with the everyman 3 hour sleep pattern which basically means you sleep for 3 hours at night and have about 4 extra 20 minute naps spaced fairly evenly during the rest of the day.

All in all, this worked very well. I eventually gravitated towards a 4.5 hour core sleep, and ended up sleeping between 5 and 6 hours per night, and I felt great. I eventually drifted back to monophasic sleep because I had to travel (Polyphasic sleep is difficult when you’re traveling) and I got sick and felt I needed more sleep.

Since then, I’ve waited for my new headband sensors to arrive from Zeo (They only last about 3 months) before going back to polyphasic sleep so that I can monitor my adaptation period. To that end, I got a few days worth of data for normal monophasic sleep after I received my sensors last week.

 

Light green is REM sleep, grey is light sleep, dark green is deep sleep and red is awake.

 

This data shows some interesting patterns:

  • I tend to have the vast majority of my deep sleep between 11pm and 1am
  • I tend to have a fair amount of REM sleep between 4am and 6am

Knowing this, I decided to try doing the everyman sleep pattern, but instead of one chunk of sleep for 3 hours, I’m splitting it up into 2 separate 90 minute chunks at 11pm and 4am with 20 minute naps at 10am, 2pm and 7pm.

The plan is to make sure that I maximize both deep and rem sleep, and see how that works out. It feels kind of like a cross between the everyman and the uberman schedules, hopefully with the best of both. If this works, I’d end up sleeping only 4 out of every 24 hours, but hopefully still have some flexibility with when I can take my naps – Time will tell.
