Polyphasing Experiment: Day 13 minute read

Today is the day it all begins. Or ends. No more bed for a week. I have just got up from a very relaxing 8 hour sleep. I feel fully rested, but a little fuzzy in the head. I haven’t had a full 8 hours for a few days.

Alertness rating: 7

I shall be taking my naps at 11am, 3pm, 7pm and 11pm as scheduled.

10:00am: Testing

Cognitive tests:
I shall be taking three different types of cognitive tests every day. These are:

  • Typing test: The score is words per minute adjusted for errors over a two minute test. Test here.
  • Simon game: Test memory of colours and sounds. The score is the number of consecutive colours I can recall. Test here.
  • Reactions: The score is a weighted speed. Test here.

  • Typing: 56 WPM
  • Simon: 10
  • Reactions: 71.47

Physical tests:
I shall be taking three physical measurements every day as well. These are:

  • Weight (kilograms)
  • Blood pressure
  • Heart rate (beats per minute)

  • Weight: 63.8 kg
  • Blood pressure: 112/56
  • Heart rate: 60 BPM

11am: Nap time!

Well, not surprisingly I didn’t sleep, but I did get two interruptions. Someone rang the door bell about 8 minutes in (no one ever rings the door bell here), and the National Blood Service sent me a text message asking me to give blood (which I can’t do for medical reasons). So never mind, I wasn’t expecting to sleep anyway. I feel slightly groggy from lying down in the dark for 20 minutes, but otherwise fine.

Alertness rating: 6.5

12:15pm: I Lost A Bed!

Before

After!

15:00: Afternoon Kip

Half an hour before hand: feeling pretty tired. There is no reason for that. I slept a full night last night, but my head feels like cotton wool. Quite looking forward to a little lie down.

Alertness rating: 5

Had a little pseudo-sleep. Not sure if I was entirely under or not, but there were what I can only describe as para-dreams. Now rather foggy in my head.

Alertness rating: 5

19:00: Evening doze

I’m definitely resting more and more as the day goes on. No para-dreaming, but a heavier 20 winks.

Alertness rating: 4.5

Bleurgh. I’m tired and cold. And this is day 1? I shouldn’t even be sleep deprived yet! I feel as you feel when you have overslept perhaps. The next sleep will be the test: I normally go to bed around 11pm, so my body will be expecting something good, something like 8 hours. It’s gonna be in for a surprise.

23:00: Night nap

Well I survived. I didn’t sleep, just some imaginative drifting. Now I am tired, properly tired like you are after a long day’s travelling just before you sink into bed. I’m not going to bed for another 30 days. At least I’ve tidied up my desk.

Alertness rating: 4

23:59pm: Testing

Cognitive tests:

  • Typing: 60 WPM
  • Simon: 13
  • Reactions: 76.69

So I improved in all areas of mental acuity. I can only conclude that my performance hasn’t been affected by being awake for 17 hours straight. I can believe that. I guess the improvement is simply down to being used to the exercises and standard variation in performance.

Physical tests:

  • Weight: 65.1kg
  • Blood pressure: 123/68
  • Heart rate: 48 BPM

Everything pretty normal here still. The blood pressure is raised, but still within my normal daily range. The weight is higher, as you would expect after a meal and full hydration.

Alertness rating: 6

Actually I’m feeling alright! I wonder if doing the cognitive tests woke me up a bit.
