sleeping diagram for March 8th 2012

Day 1


It is 4am.  I’ve had a core sleep of 4:40.

  • 1:15 of REM, 
  • 2:34 of LIGHT
  • 0:50 of DEEP sleep.

I found it quite easy to get out of bed.  There was some excitment about starting this experiment, and doing stuff at 4am.  Curiosity and making this experiment work are a good motivator so far.  The feeling after waking up was a little drowsy but I was soon reading about web programming (ZEO APIs ) and doing some chores (online purchases, tidying and such).  Overall it just feels like one of those early work days when you have to wake up quite early.   But will my body need the naps at the right time?

These diagrams generated by ZEO, show the sleeping phase in 5 minute bars.

Since I woke up at 4am, around 9:30 I started feeling quite sleepy.  A little distracted too.  So I dove straight into my 11am nap.

Interestingly it only took me approximately 6 minutes to enter the REM phase which lead direcly to light sleep and finally deep sleep.

My 17:00 nap was a bit lighter (after some light exercise and walking)  but I did reach REM and light sleep.

Overall I would say I’m tired.

My core sleep has been decreasing in the last 4 days as follows:

8:00  –>   7:05   –>   5:18   –>  4:40 

My 2-nap everyman today was productive but tiring.  I’ll have another shot at it tomorrow.

  1. We are following your progress with excitement… Ánimo!! From… Seattle (CROI)


  2. Esentially, because with a 9h time lag, we must we feeling like you are!!

  3. Hi Sergio. Good to hear from you. Good luck at CROI! Make sure you keep those retro-viruses at bay 🙂 I would say jet-lag traveling West feels a little different. You try to stay awake until you can’t anymore and sleep all the way through until you wake up in the middle of the night.

    In my case (so far) I’m just feeling a little sleepy at various times of the day. More like a roller coaster. By the way … maybe you can recommend a magic probiotic potion to take me from “everyman” to “überman!” 🙂

  4. hey all the best! it is exciting to see ur progress. I saw that you are taking a weekend break. Is this not going to affect your sleep cycles? Is that allowed? Just curious 🙂

  5. Hi Pavi, Thank you for the encouragements. I think I didn’t express myself properly in the previous post. When I said “it’s the weekend!!” … it was just a happy exclamation but I’ll continue the schedule every day. Today (Saturday) is 3h core sleep, tomorrow too, and then I’ll switch to full 6-nap schedule on Monday. Hope all is well with your new job. 😉
