day 12 – Zeo Troubles

| 3 Comments

If you don’t know about polyphasic sleeping read this first.  Today I slept very well.  I had REM on all naps, and two nice periods of REM in the core sleep (It may be true that doing 3:20 instead of 3:00 core sleep on Everyman has benefits.  One of the readers seems to think so).sleeping diagram with zeo ... missing naps

Anyway, I keep having some problems with the headband (or Dry EEG to record the sleep phases).  The machine is quite astonishing, light and comfortable.  But the developers had a big blind spot when it comes to designing the database.  The charts above are not the output of their website.  All the charts you see here are practically done by hand.  I have to copy paste, adapt, scroll, select by color, open, crop about 4 times. All that to make a little chart like that one!!  The reason is pretty simple.  Zeo thinks that everybody is monophasic.  So they will only save the longest period of sleep.  If you don’t pay special attention to your naps and record them on separate files they will just disappear from the record.   Not good for polyphasic sleep, of course.  So if you stop the alarm and put the headband in the docking station.  POUF!  Gone.  I did remember the length of the naps, and the dreams (REM) at the end of it.  So I’ve drawn in beige a rough estimate of the nap.  Anyway … I’m going to develop my own scripts to record the data and do my charts automatically.  This is roughly how it will work:

My headband talks to the phone and docking station.  Then my phone uploads the data to their website.  I use their website API to pull the data back to my computer regularly (I have to check if I can grab the full naps or just the core sleep). Then I convert it to a useful format, merge it with my personal subjective observations, and create automatic charts from the data with SVG-fig.  Wherever you see the funny cat it means I will share this code on Github (a place for developers to share and collaborate).  Anyway, I’ll keep you posted.  When I’m done I’ll share the code so anybody can plot their own data this way.  Wish me luck!

(2012/03/19, (2:30, 6, “just woke up”), (3:50, 7, “reading”), (4:27, 6, “computer work”), (5:40,5,”getting tired for reading”), (6:27,4,”ready for nap”), (7:35,5),(7:50,7),(8:30,7.5), (11:30,7.5), (12:00,5),(13:00,7.5),(17:00,6,”tired eyes and light headache”) … all good until 22:30.)

  1. Hi, great site and much more awesome posts. I just wanna drop a line of great interest in your finding and reports. I am currently on day 3 (today overslept with gf, but got over it) and writing bachelors work on E3 with cognitive self-testing. I am writing in English, I am Czech though, so in a few months I’ll have some light scientific evidences or at least methodology, how to and how no to go polyphasic sleep.

    You give me great inspiration and good advices, thank you! I had some experience with E3 moreover for last 4 years, but it’s important to remind some things from time to time (e.g.: I’ve already forgot gf is sleep sucker :D, no more meeting in her bed!).

    Keep going! =)

    Best wishes

  2. Hi and Dekuji Schmutzka,

    It’s great that you’re doing your bachelors around E3. What degree is it in? Are you approaching it from a psychology / medical perspective? And what kind of cognitive tests are you using. It could be interesting for me to do some tests at various times of the day to check the evolution, so if you need some guinea pigs (but not too time consuming) I may be able to lend a hand.

    Best of luck with your E3 schedule. (Are you using 20mn naps?)

  3. Oi,

    well I started writing slightly in January, more deeply this month. I study psychology, so from this point, from point of cognitive abilities to be specific. I tried to get some polysomnography, eeg, hormonal measurement, but it would be way to hard to cover all of those effectively and in complex.

    I use 1) test on short-therm memory – 40 word 2 mins, 2) “click when you see red point” alertness test, 3) then two D2 test – cross all object made by 4 dots from line and 4) trail-making test. I am doing single-case experiment. But I can open test for you, if you want (a bit more programming for me). I tested myself on monophasic and now, to have a comparison (my topic in very simple words).

    I am using around 27min naps with falling asleep (3-4). I share flat with 6 people and also nap in school, so sometime it’s not easy to fall asleep. I’ll try to cut it down while adapting.

    I have one think on my mind. Every 1st phase (7-12) I have problems with getting up from bad soon. Usually I end up lying for one hour more. No matter how many alarms I have… maybe I could go to school in the morning, that could help me.

    Thanks you for doing it!
