The Science

Take a Nap! Change Your Life by Sara C. Mednick – Very interesting and accessible book about the joy of naps.

See Sara in this Google Author Talk in which she addresses the whole scope of the book and also a lot of very pertinent questions from the audience – including one about Uberman.

Polyphasing Experiment: Conclusions

Things I achieved in the week:

  • Cleared out the loft.
  • Cleared out my bedroom – wardrobes, desk etc.
  • Threw out a load of clothes, books and general crap.
  • Sorted out my computer filing system.
  • Gave my website a complete overhaul.
  • Started a new money making venture.

Lessons learned:

  • I can sleep for 2 hours a day and still operate (more or less).
  • There are no serious side effects (I think!).
  • The limits of my endurance are much further than expected. I feel like I would be able to operate on 14 hours of sleep a week in extreme circumstances.
  • Sleep is something that can be trained and it can be modified to my own requirements: it’s not just a case of going to bed and waking up.
  • Naps are more important than I gave them credit for. The ability to nap every few hours to get through a night of work was a great feeling.
  • Without the habit of going to sleep for 8 hours straight I lost the sense of days passing. Time flowed constantly, not in fits and starts. It made me realise that every minute is sacred. 
  • With 22 hours in a day there’s far too much time to spend it on frivolity – that gets boring pretty quickly. I found that the more time I had, the more I wanted to spend it on something worthwhile.
  • It’s nice splitting the day up into more segments: it focusses the mind on achievement during the waking periods. Under this system of 20 minutes every four hours, however, I become something of a slave to the segments.
  • Beds are not necessary – and in fact I found it much nicer not to have a bed in my room. The bed, that huge piece of furniture, forced my room to be a BEDroom. This is counter productive both for working in that room and then for trying to sleep in that room after having worked there. It was really liberating to use a blow-up bed that I brought out only when required. It meant that I had a huge lump of space for other daytime activities. It meant I could put my rocking chair beside the window – I had never before realised how pleasant the sun was coming through there. The absence of a bed in my workspace lead to a healthy demarcation of day and night activities.
  • I like doing things that make me unique. I like to push myself into unusual situations that change my perception of the world – and then to encourage others to do the same. I like living with imagination and courage, not conformity and fear.

Positive aspects of polyphasia

  • Time for EVERYTHING – including complete and utter boredom!

I will have to let that time go on a monophasic schedule.

Negative aspects of a polyphasic pattern:

  • Socially it is difficult at best, antisocial at worst.
  • I found it difficult to perform creative work, in the adjustment phase at least. I got a lot of dross work done, but not much creative work – my novel suffered by about 2800 words over the 6 days of the experiment.

Negative side effects of polyphasia

These, I concede, could have disappeared if I had persisted through the adjustment period of about 30 days.

  • Hot flushes in the early phases.
  • Numbness in the extremities.
  • Cold sensitivity.
  • Digestive problems.
  • Brain freeze/fog.
  • Creativity blockages.

Action points to be taken away:

  • I don’t need a bed. Perhaps I should investigate buying a Japanese bed roll.
  • When I feel tired, I’ll sleep! I won’t feel guilty about sleeping or just ride through the rough period. I’ll take a nap. I know now that I don’t have to get undressed or brush my teeth or anything – I can just lie down and take 20 minutes out.
  • Evangelise the benefits of messing with your sleep to learn about yourself.

Finally, I exhort you: Experiment and Learn.

Thank you for reading.

Polyphasing Experiment: Day 6

01:51: Revenge of the Nap

I have had a change of tactics. Naptics you might say. Taking Pavlina’s idea and combining it with Buckminster Fuller’s technique: I’m just going to take a 20 minute nap every time (well, maybe not every time) I get too tired.

I just had one and it was unquestionably more successful than other naps. I am still scarcely able to keep my eyes open, but I did have vivid dreams and woke up before the end of the nap. These are good signs. I am still hunting the holy grail of refreshment, however. But at least I’m not tired!

Alertness rating: 4

03:20: Naptastic?

I’m not sure if I’m winning or losing. I think I feel better, although my eyes are having trouble adjusting to sight again.

Alertness rating: 4

06:40: Serial Napper

My schedule for this past night has been naps every 2 hours, rather than every 4. so that’s naps at 11pm, 1am, 3am, 5am and, coming up next, 7am. It has made it somewhat less painful to get through and I have achieved things, but I am still far from rested.

Alertness rating: 4

Disgusting: a 1 hour oversleep after initial wake up. Actually that’s not quite correct: I woke up an 20 minute intevals at 7:20, as planned, at 7:40 and then at 8:20.

18:34: Thoughts on Napping

There are some things that I have not been describing because I have not been sure. But I think now they are pertinent. A week ago I played cricket and did not stretch beforehand. Normally any strains would be gone in three days at most, but the pain in my back seems to have got worse.

Secondly, this sleeping pattern seems to have been playing havoc with my digestive system. This could be due to lack of an enzyme that is produced during deep sleep. Having said that, after two bike rides I am feeling pretty good – but that could just be thanks to watching Liverpool trounce Aston Villa 5-0!

Tonight is something of a test for the system: it is the first day that I have been able to socialise. Two of my friends are in town and we’ll probably go somewhere this evening. I obviously can’t go out until my 7pm nap, can’t drink and have to be back in bed by 11pm. I shall report back on the irritation this causes.

I have to confess that this experiment has been both easier and harder than I expected. I was expecting much more acute symptoms of sleep deprivation: hallucinations, narcolepsy and so on. I had none of these. But I have been really dragged down by the minor side effects: the dullness of thought, the hot flushes, the digestive problems, weakness when performing physical exercise. I have the time, but not the strength.

I do feel like today has been an improvement, however. Perhaps that is due to my oversleep earlier. Perhaps it is because my friends are here and I have someone to share it all with. Am I fed up with it though? Is it too much already?

Reading Dr Mednick’s book I am even more concerned with the long term effects – this was only meant to be an experiment, but is it worth the heartache just for an experiment? This 30 days could be spent productively – it’s not as though there aren’t a million things I need to be doing, but if I don’t have the strength then all the hours in the day won’t help me.

Alertness rating: 5.5

Still a thick head though, and that just kills me.

19:38: Sleep Inertia?

Seriously, waking up from a nap feels like waking up from a high speed encounter with the bull bars of a truck. I can barely focus my eyes, which is worrying – even after repeated shaking of the head etc. I wonder if this is because I am sinking quickly into short wave sleep and thus getting a load of sleep inertia on wake up. But once up and moving I feel fine again.

Alertness rating: 5.5

23:57: Nap to the Future

The evening with my friends was, predictably, terminated by me needing to nap. Post nap was the familiar feeling of being kicked in the face by a mule. As the clock ticks towards midnight I have trouble holding a conversation without feelings of great irritation and discomfort. This experiment is over.

Alertness rating: 4

Polyphasing Experiment: Day 5

3:00 Please let me recover!

Not the worst nap ever. But I’m still waiting to wake up refreshed. I’m lurching from nap to nap with my body just getting enough to keep going. It’s like I’m topping up to the level of sleep deprivation that I built up over the first night of not sleeping. Like the 20 minutes gives me just enough energy for the next 3 hours 40 minutes, no more, no less.

One other observation about this is that I really can’t read whilst in this phase. It makes me too sleepy. I can manage a few pages during the day, but even then I’m not really concentrating so I’m pretty sure it’s not very productive reading.

05:09: Testing

Cognitive tests:

  • Typing: 61 WPM
  • Simon: 9
  • Reactions: 82.38

Simon has taken a bit of a battering – concentration not great. But the others are fine.

Physical tests:

  • Weight: 65.2kg
  • Blood pressure: 112/72
  • Heart rate: 48 BPM

Absolutely normal physical tests.

08:56: Interdiurnal Nap?

I experimented with a nap between naps. I feel more rested, but have a feeling that it is only going to make things worse. I napped from 7:00 to 7:20 as normal, then got up and had a shower and napped again from 7:40 until 8:00. I then did a silly oversleep thing until 8:45. It really is odd that my sessions of oversleep are 40-45 minutes, not 90+. I wonder if this means that a 45 minutes Dymaxion would be possible for me?

Alertness rating: 4.5

17:34: Keep on napping

And hope it works out. I’m a little concerned that I don’t seem to be dreaming so much. Both the 11am and 3pm naps were more like falling into a faint and only rousing when the alarm goes off, what seems like hours later with a brain turned into oatmeal. My condition does seem to improve after waking, but I still struggle to read in my rocking chair. I feel dehydrated a lot of the time and exercise drains me. I’ve been for a long walk and a 15 minute bike ride and both left my head dense and craving sleep.

Alertness rating: 4.5

23:16:Torture?

Is this self-imposed torture? Sleep deprivation is a well-known technique and I have no gone five days without a decent deep sleep, always waking myself before the truly restorative phases of sleep.

Alertness rating: 3

Polyphasing Experiment: Day 4

02:21: Night Walking

I hope I develop a taste for dark, cold streets because I feel like I’m going to see them a lot over the next month. I find myself looking forward to the 7am nap because it seems like a true rest. When I wake up it is morning, just like for all the monophasers. It is a rare time of day when we are in sync, there is one other at 11pm when we all go to bed, ‘Good night!’ I say, knowing that I’ll be back up again in 20 minutes, but the others will slumber through the night, through to the morning.

Alertness rating: 4.5

04:16: Quiet Zone

That last nap wasn’t too restorative. Apparently night naps are harder than day naps. My body is still used to sleeping at night. But I have to say that I’ve been working on my cycling project quite productively in this quiet zone without too overwhelming feelings of tiredness. Still got two and a half hours to go though before the next nap!

Alertness rating: 4

07:22: Grogg

Dreaming again, but woke up to my alarm. When that happens I feel very groggy, especially if it was during a vivid dream, which it was this time. The dream took place on a film shoot. I was an extra and they needed me to eat a sandwich on camera. But they gave me the sandwich before the shot was ready and I ate it. So I felt bad and they had to make me another one. And I ate it again. Oops.

My eyes feel like they can’t focus, with heavy lids and a mist shading them from the world. Similar to yesterday morning actually. Not good.

Alertness rating: 2

09:20: Testing

Physical tests:

  • Weight: 64.1kg
  • Blood pressure: 121/61
  • Heart rate: 52 BPM

Absolutely normal physical tests.

12:12: Snoozeville

My 11am nap was the same story. Good long sleep with REM, but the alarm wakes me and I have no idea where I am, what the time is, whether I am just going to bed or should be getting up. I’m still feeling head fuzz.

Alertness rating: 3.5

16:12: Experimentation?

I’m not sure if this counts as valid experimentation, probably not, but I did oversleep again, like I did yesterday on my 3pm nap. Perhaps my excitement over adjusting was waaay too premature. Again, it wasn’t a problem of alarms. I clearly recall switching them all off this time, but I chose to stay in bed. It is interesting that, even after choosing to stay in bed, I am only oversleeping by 40 minutes. That makes my sleep time 20 minutes + 40 minutes. I also never remember dreams from this second 40 minutes so I am definitely indulging in the NREM bit. But what does it all mean?

I’ve just re-read Steve Pavlina’s blog about the adjustment period and he didn’t feel 100% until Day 6 and even then still used an extra 20 minute nap in the early hours before dawn. I’m pretty sure that my two 40 minute oversleeps are more damaging than his extra 20 minute sleeps for the reason that I am not going straight into REM sleep, which is the purpose of this initial training, adaptation period. Does that mean that my body is ‘reset’ and I have another 6 days of perfect scheduling to get through? Or are two relatively minor oversleeps permissible and my body will be on track for 100% on my day 6 equivalent (which would be next Monday)?

One thing that I did not do for this nap was to place the alarms out of reach – a policy I implemented after yesterday’s oversleep – the problem is I went to bed about 15 minutes before nap time to adjust and read and I needed a clock to see the correct time to close my eyes. I shall move another clock to viewing distance and keep my alarms out of arm’s reach!

Alertness rating: 3.5

20:03: Napping for Napping’s sake

Well that nap didn’t feel very restorative at all. I woke up about 10 minutes in worrying that I had over slept. It feels like I am getting all the right symptoms of polyphasic sleep, but none of the benefits (yet). I’m going to work tonight on clearing out Liz’s loft so that should keep me wide awake and make the hours of darkness pass.

Alertness rating: 3
But after a big meal, Alertness rating: 4

01:45: Another Day’s Nap

My 11pm nap was no more than functional. It’s amazing how easily I fall asleep and dream, but they are not restorative. I just get up and resume my zombie routines. I can’t remember the last time my brain felt engaged. Scary.

Polyphasing Experiment: Day 3

00:40: Midnight Creep

The ‘day’ begins with me dragging three huge bags of clothes down to the Salvation Army collection point in the centre of the village. As I stuff the dense black bin bags into the skip I feel guilty, as if they were chopped up bodies and I were a 1920s gangster.

Alertness rating: 5

Surprisingly alert.

02:28: Epiphany

This really is remarkable. Here I am at half past two in the morning and yeah I don’t feel 100%, but I can function quite well and I do have enough energy and concentration to do the sort of tasks that suck hours out of our days (or just don’t get done at all). And to think that this is the worst of the adjustment period; I can’t imagine what it must feel like to have energy at this time of night on just 20 minutes napping time. I do look forward to the naps now and I think my brain would really love me to forget to set the alarm but I’m on track and loving it.

03:22: Changes

I feel as if the nap length is increasing. Of course it isn’t, but that’s the way it feels. It seems like the naps are a few hours, not just 20 minutes. I’m still not awaking refreshed though. Exhausted.

Alertness rating: 2

07:59: OUCH

I feel sick, I can hardly keep my eyes open, I’m very sensitive to cold. This is the pain.

Alertness rating: 1

I hope that’s rock bottom, but there is still room for worse I fear.

08:15: Testing

Cognitive tests:

  • Typing: 64 WPM
  • Simon: 9
  • Reactions: 69.47

I’m getting better at the typing! The other worse scores better reflect the way I feel: rubbish!

Physical tests:

  • Weight: 63.5kg
  • Blood pressure: 108/62
  • Heart rate: 56 BPM

Absolutely normal physical tests.

11:27: Rushing Naps

They seem to be coming quicker. I don’t feel sick any longer: I just needed to eat breakfast. I am still whacked; this seems to be a hangover from each nap. I am groggy apparently. Also worth mentioning: I appear to have a cold, something happened yesterday about 6pm and my nose has been liquid ever since. Probably not making things any easier, but I don’t think it is affecting me too much.

Alertness rating: 3

16:00: Disaster?

I have no idea how, but I somehow managed to oversleep there. The alarms were all switched on and I woke up naturally 40 minutes late. I have a distant memory of possibly turning them off and just lying there for a moment… I’m a little groggy, but otherwise fine. I hope that has not put be back too far!

Alertness rating: 3.5

19:18: Back on Track

And I dreamed and woke up naturally for the first time! Woo-hoo! My dream was based in a middle eastern city (probably because I wrote 1000 words of my novel just before napping) – it could have been Cairo, it could have been Tunis – it was a melange. Anyway, I was there to learn Arabic and I was in a school room and there were two lesbians (I later assumed – but don’t worry, it’s not one of those dreams!) who came in and asked us if we wanted to watch some comedy sketches performed by two lesbians in French. I was surprised and pleased that they were so open about the homosexual content. I wondered if they were rebelling against the society or just determined to live their lives as they felt them, with no shame.

So: dreams, real dreams. I still don’t feel totally fresh, but this seems to be something of a break-through. And the fact that I woke ‘naturally’ – I use the quote marks because after the 16:00 nap I was worried about oversleeping and I woke in something of a shock thinking that I had overslept again. This also seems to be a constant in ubersleepers’ reports: the impression that sleep lasted much longer than 20 minutes.

Alertness rating: 4

And to celebrate my first successful polyphasic sleep:

White Hot Chocolate!

22:07: Testing

But first:
Alertness rating: 6 – I’m impressed.

Cognitive tests:

  • Typing: 62 WPM
  • Simon: 17
  • Reactions: 84.67

Typing speed was up, but accuracy was down. The other scores blown out of the water! If that is in any way indicative of the results of a good polyphasic nap then I’m in for a treat! Reaction speed up 22% from this morning – wow.

Physical tests:

  • Weight: 64.0kg
  • Blood pressure: 114/68
  • Heart rate: 61 BPM

Absolutely normal physical tests.

23:21: Good Night!

Or not. Dreamt again, but woke with the alarm. Feel very drowsy and just wish I could go back to sleep!

Alertness rating: 3.5

Polyphasing Experiment: Day 2

00:14: New Territory

This is the start of my first full day of polyphasic sleeping. Yesterday was great, but on the back of a full nights sleep it was no challenge. Today is a different kettle of fish altogether. Over the next 24 hours I will discover what it means to be sleep deprived. And it’s just the beginning.

Alertness rating: 6

03:00: Early Morning Nap

Got some light sleep in with a little para-dreaming: a marching band drummer with a big old drum strapped to his chest beating a marching rhythm. I woke up in surprise at this visit, only to realise that my brain was interpreting the music I had playing in the background.

I am napping on the floor with a duvet and a pillow, with a small lamp on and some soft music playing. I don’t want to make this harder than it already is by oversleeping! I am setting five different alarms, one on my phone which is fairly obnoxious and then four on this Salter Kitchen Timer I got off Amazon, each one set one minute later than the last. They all have different sounds and I haven’t needed more than one – so far…

I’m going to head out for a walk now to keep myself conscious – I’ll probably have a bite to eat as well. Only one more waking phase until I’ve done 24 hours. Steve Pavlina had to do three 24 hour polyphasic ‘days’ before he started feeling good again. There is no doubt that the hardest is ahead of me. So far I’m feeling alright.

Alertness rating: 4

Piano is an excellent tool for staying awake, as I thought. I only hope I didn’t wake the rest of the house up! Played for about an hour – Dos Gardenias and a bit of Gonzales. I’m quite hungry now actually – I haven’t eaten a full meal since about 5pm yesterday.

06:16: The Night Shift

The hardest part of the day is almost over. I got through the last hour by writing my 1000 words of novel for Tuesday. I did notice that it was harder to think straight, but once I got going it was fine. Dad is up already, dawn has broken. I have officially made it through the night.

Alertness rating: 4

7:20: Morning has broken

I’m yet to have a decent nap. This one was a kind of unconscious rest. Not particularly refreshing and I didn’t really dream, but I did sleep. This 7am nap will be akin to a monophasic sleep: I will now have a shower and breakfast.

Happy days! What a difference a good hot shower makes! Ready to face the day. Except every time I think that, I can’t help thinking that it’s not merely the day I have to face: it’s the next 30 days. I will never rest, not like I used to, and that simple fact is a mind bender.

Alertness rating: 5.5

08:52: Testing

Cognitive tests:

  • Typing: 60 WPM
  • Simon: 10
  • Reactions: 68.34

No change in typing accuracy or speed. Lower scores on both the concentration and reaction tests, however. I’m not surprised – I feel pretty slow.

Physical tests:

  • Weight: 63.8kg
  • Blood pressure: 113/56
  • Heart rate: 59 BPM

Absolutely normal physical tests.

11:00: Mid Morning Already?

Still no proper REM sleep. I am definitely sleeping though. It took about 8 minutes to fall asleep, about 2 minutes once I’d switched off the rather lively Cuban music…Feeling very fragile and sleepy.

Alertness rating: 4

14:32: A Walk in the Sun

It’s boiling out there! An hour long walk through the fog of brain fuzz and boy am I looking forward to the 3pm nap!

Alertness rating: 3.5

15:21: Afternoon Kip

Better, better. Slept the whole 20 minutes thanks to extending the alarm to about 25 minutes and doing a bit of reading before sinking into slumber.

Alertness rating: 4

Just fending off the zeds.

19:20: Evening Session

One really needs to prepare for one’s sleep about 10 minutes before the nap actually begins. I was clearing out the loft and didn’t lie down until 19:00 precisely so didn’t fall asleep for perhaps 8 minutes. This meant a shorter nap than I’m supposed to be getting and as a consequence I feel like death!

22:26: Testing

Cognitive tests:

  • Typing: 57 WPM
  • Simon: 10
  • Reactions: 78.41

Slightly worse accuracy in the typing test. Interestingly I was a lot quicker on the reaction test. Not sure what that means!

Physical tests:

  • Weight: 64.5kg
  • Blood pressure: 112/64
  • Heart rate: 64 BPM

Absolutely normal physical tests.

23:27: ZZZ

Wow. I just slept the whole 20 minutes, possibly a fraction more. Woke up in another dimension, not sure where I was. I’m really feeling the pull of sleep now.

Alertness rating: 2.5

My eye lids are being dragged down by an invisible force. I should get up out of this chair and do something before I fall under the spell.

Polyphasing Experiment: Day 1

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.

Polyphasing Experiment: Testing, testing

Today I was analysed by my psychologist. One hour of intensive testing at the Starbucks in Covent Garden (Peppermint tea please). I’m not sure if I am normal, but at least we’ve put down a marker for the end of the experiment.

These tests assess attention, concentration, memory and my executive functions, i.e. problem solving and decision making. The theory is that sleep deprivation will make these processes sloooower.

The tests were:

  1. Visual memory: copy a complicated geometric drawing, then draw it from memory immediately, then draw it from memory again 30 minutes later.
  2. Trail making: point to numbers on a piece of paper in numerical order, then with the letters of the alphabet and numbers in alternation (1, A, 2, B etc)
  3. Zoo map: trace a route through the zoo following various rules and injunctions.
  4. Wechster memory scale: listen to a story and then repeat it back, marked for story details and themes. Then retell 20 minutes later.
  5. Verbal fluency: name as many animals as possible, then as many words beginning with ‘F’ in one minute.
  6. Verbal paired associates: given pairs of nouns, e.g. Elephant, Glasses, then have to produce the pair when given its other half immediately and then again after 45 minutes.
  7. Letter number sequencing: given numbers and letter jumbled up, then have to sort them and repeat back in numerical and alphabetical order.
  8. Digit span: given sequences of numbers, then have to repeat them back in the same order as given. Then more sequences of numbers, but repeated backwards.

My results were:

  1. Immediate reproduction with no mistakes; 30 minute delay with 4 mistakes.
  2. Numerical order: 16.24s; Numerical and alphabetical order: 33.65s
  3. Successfully completed in: 1:46.29s
  4. Logical memory test 1a: 13/25 story units; 6/7 thematic units. After a delay: 10/25 story units; 6/7 thematic units. Logical memory test 1b: 14/25 story units; 7/8 thematic units. With a second reading of the story: 19/25 story units; 7/8 thematic units. After a delay: 19/25 story units; 8/8 thematic units
  5. Animals: 40; F words: 23
  6. 100% recall immediately and after 45 minutes
  7. 13/21 sequences correct.
  8. 8/16 sequences correct; 7/14 backward sequences correct.

We will test these again at the end of the experiment to see how many of my brain cells have died.

Polyphasing Experiment: The Challenge

It was midnight and we were totally exhausted. We were sitting up late again, relaxing in the office at Makan, a cultural centre in Cairo. We’d spent the last two weeks working long days on my friend’s PhD fieldwork and now you couldn’t have kept our eyes open with matchsticks. Our heads were drooping into our beers and our metabolism was crashing after the sugar high that had fuelled the last few hours of frantic archaeology.

We wanted to celebrate finishing her research which had been a succession of progressively more intractable problems one after another. Our necks were stiff from bending over the microscope and our arms were aching from sieving endless archaeological samples. We just felt like we deserved to relax and enjoy ourselves, but with only hours to spare before our flight home our bodies weren’t willing.

Opposite us was Ahmed al-Maghrabi, the tireless manager of Makan. He was boasting that he hadn’t slept the previous night. Just what we needed to hear, this man in his fifties casually telling us that he’d spent all night at a film première and hadn’t slept a wink. We sat there, supposedly in the peak condition of our lives, flagging horribly and feeling rather pathetic opposite this insomniac. It didn’t seem fair and I told him so. What he said was to change my life. ‘Well you know Leonardo Da Vinci only slept 2 hours a day. Not that I’m comparing myself with him, but you know…’

That woke me up. I’m interested in what you might call lifestyle design. Last year I spent forty consecutive days getting up at dawn in an attempt to become less of a lazy bones. Turned out the reason I was so ‘lazy’ and sleeping an awful lot was because I had an underactive thyroid, but the experience was a real eye opener and great fun. I have been looking for something else to do ever since and here, with the warm night air of Cairo blowing through the curtains, I sensed an opportunity.

‘Really? Two hours a day? That’s impossible, surely?’
‘No, no. It’s all documented. Two hours a day, that’s all. He just slept for 20 minutes every four hours.’
‘That’s incredible. Just imagine – you’d have six more hours a day awake. That’s a quarter of a day! You could squeeze an extra 3 months into every year! No wonder Leonardo Da Vinci got so much work done.’

At this point my companion interjected, somewhat brusquely, that I was still an inveterate lazy bones and wouldn’t be able to find anything productive to do for that extra six hours anyway, so what was the point? Ah ha. A dual challenge: sort out my life so that I need six extra hours of work/play time a day and therefore need a sleep schedule to match the greatest genius that has ever lived. ‘I’m gonna do it!’
