Day 13 - Making the experiment scientific

We wouldn't be scientists, if we just slept without monitoring and evaluating our sleep. We already started with the Sleep Cycle iPhone app, but we questioned its accuracy. Thus, our new sleep gadget arrived in the mail yesterday:
This baby is actually able to read your brainwaves and determine whether you are awake, in light sleep, deep sleep or REM sleep. I used it for my core sleep last night and got the following results compared to the iPhone app:



According to this, the iPhone app seems to determine deep sleep pretty accurately, but is not able to distinguish between awake and REM sleep. As of today, I will not use the iPhone app anymore.

But more importantly, let's look at the sleep graph the ZEO gave me: I fell asleep after only 5 minutes, whereas the average person of my age needs about 18 minutes to fall asleep. I immediately dived into deep sleep after 15 minutes, which is comparatively fast. My total time of REM sleep for the night adds up to 1h 17m, whereas the average per night for a person of my age is 1h 36m. For deep sleep, my total time was 49m, the average is 1h 23m. To remind you of the total time I sleep: Only 3 hours per night. The average total time for a person of my age is 7h 16m.

As you can see, compared to an average male of my age, I only got 44% of the total sleep, but 59% of the REM sleep and 78% of the deep sleep! I think, this is amazing. Apparently, my body realizes, that it does not get as much sleep as usual and it automatically adjust the ratio between the sleep phases, so it gets what it needs to recover and feel rested. This totally explains, why I feel so amazingly good during the day. Also, I did not wake up a single time during the night. The average person of my age wakes up 2 times per night and stays awake for a total of 16 minutes. I was awake for 0 minutes!

So far, we only talked about my core sleep, but not the naps. I haven't tried the ZEO for my naps yet, but I will do it today. I think, I can add a lot more REM sleep and maybe I can even get to 100% for REM and deep sleep. I will let you know!

By the way: If you want to get a ZEO for yourself, I recommend the following link:
You get $15 off and free shipping, which is usually $14.95. Unfortunately, it only ships to the US, so if any of my friends from Germany wants to have one, just shoot me an email. I can ship it to Germany or even bring it the next time I come over.

Day 8, 9, 10, 11, 12 - Getting past the zombie mode

Recently, we found out that what we experienced last weekend was the 'zombie phase':

http://lavalamp.trypolyphasic.com/2009/12/16/polysleeping-lavalamps-official-adaptation-guide/

Apparently, this is the time when your body starts to realize that it's getting too little sleep and tries to adjust to a 3 hour sleep instead of an 8 hour block of hibernation. This caused an upheaval of our sleep schedule last weekend and if you can recall from the previous posts, it is characterized by extreme sleepiness, fatigue and inability to function as a human being.

Thankfully, come Monday, things took a turn. Yes, the mornings are still a little rough (sleepiness but not really fatigue) but compared to last weekend, this is nothing. I feel like we have overcome the 'activation barrier' to transition from a monophasic sleep to polyphasic sleep.

Thomas already felt rested in the mornings and did not have a hard time getting up for the last 3 days. We are getting there!

Day 6, 7 and 8 - Trials and tribulations

Day 6 was quite uneventful. I was running overnight experiments in lab and I had to sleep there anyways so I took my core sleep there. Woke up to have breakfast at Cajun kitchen (yummm) and the rest of the day just went well, pretty much.

Day 7 was absolutely painful in the morning. Upon waking up, I was struck by a strong urge to go back to bed and sleep more, which I did for about 30 mins. Then I had breakfast and took an earlier nap from what was scheduled. Bad idea. That night I had such a hard time staying awake until 3 am. Eventually I did after almost falling a sleep several times and woke up with, you guessed it, sleepiness! This time, I fell back to sleep for an extra hour.

Day 8: After the fiasco with the sleepiness in the morning, everything worked out fine again today. I took my naps according to schedule and did not feel sleepy or tired during the day. In fact, I was running around like a headless chicken trying to get work done (oh, grad school!). Once again, I'm reminded why I started this sleep schedule in the first place: too much to do, too little time to do anything. Uh oh, I something going wrong with our schedule. Thomas just went in for an extra nap after oversleeping by half an hour his 11 pm nap. I hope this doesn't throw him off schedule for the next couple of days. So far, the before and after of the core sleep seems to be the problem. I read online that your body gets used to the nap but needs time to adjust to the core sleep so that it doesn't need the 8 hours of sleep it normally gets. Hopefully, this marks the turning point to a good fulfilling core sleep if we get through this phase!

Day 5 - Finding new gadgets

Anthony:

Here's how a typical polyphasic Thomas vs. Anthony sleep goes. On the top is Thomas "brainwave" sleep champion with a sleep pattern that goes through all the sleep cycles, which is supposed to be good. On the bottom is Anthony "brainwave-less" sleep loser who went straight to deep sleep and woke up an hour later, way before the scheduled 6 am waking time. This is an indication that the brainwaves that Thomas uses during his sleep is actually helping him adapt to the Everyman sleep schedule. I, on the other hand, fell asleep for an additional 30 mins after I woke up at 6 am. Despite feeling very sleepy when I wake up, at this stage, I don't feel as crappy when I wake up, just sleepy. My body is slowly adjusting to this sleep schedule, albeit at a slower rate than Mr. Thomas. It is also noteworthy that I set my alarm clock wrongly when I took my 10:30 pm nap last night and overslept (I did 1 hour instead of 20 mins). Consequently, that might've affected my sleep patterns during my core sleep. This marks our progress on Day 5.

I don't know if I have mentioned this in the previous posts but the first nap that I take around 11 am / 12 pm is always the best one. I feel immediately energized after that nap and that is the most productive time of the day (not that the other hours are unproductive).

Thomas:

Again, my alarm did not go off today. What is wrong here?? In the afternoon I found out, that it would be a good idea to set the alarm time to 6.00 am instead of 6.00 pm. I will try again tomorrow. ;-) Nevertheless, I got up at 6.13 am after already being awake for one hour. I realized, that I was awake before 6 am since I could hear the brainwaves, but I did not know it was that long. I tried to fall asleep again, but did not succeed. My body seemed to have gotten enough sleep.


My sleep graph shows, that during the short night of 2 hours, I passed through all different sleep stages and apparently, my body gets all the sleep types it needs. When I woke up, I did not feel tired again and had a great start into the day.

I had a lecture from 10 am to 11 am and felt slightly tired during this time, but it was only a short period. My first nap was scheduled for 1 pm due to a meeting at noon and I had no problems to stay awake.

In the afternoon I found another gadget for my sleep:

It pretty much does the same like the Sleep Cycle app, but uses scientifically proven methods to determine the sleep phases and - most importantly - a wrist band to determine your movements, which is way more accurate than just the movements of your iPhone on the mattress. It has some more interesting features to determine what influences your sleep in a positive or a negative way and judges your sleep quality. Unfortunately, they are out of stock at the moment, so I pre-ordered one. Maybe we can compare the Sleep Cycle app and the WakeMate very soon.

I feel like really getting used to my new sleep schedule...

Day 4 - Distraction from fatigue

Last night I got home from work at 1 am. I felt kind of sleepy for the last 30 minutes and wanted to be awake again. Fortunately, our next 'crazy project' arrived yesterday:


The largest jigsaw puzzle in the world with 32,256 pieces (http://www.passionforpuzzles.com/weblog/2010/08/largest-jigsaw-puzzle-ravensburgers-double-retrospect-32256-pieces.php). So, I started sorting the pieces by color. I could focus on the puzzle without any problems and felt awake again after 10 minutes. At 2.45 am, 15 minutes before my scheduled core sleep, I decided to play the piano to see if I am still able to. There was no problem at all and no difference to playing at daytime with a monophasic sleep schedule. I could concentrate and focus on everything during the whole day starting at 6.30 am and ending at 3.00 am.

Again, I used the brainwave tool to induce sleep and set it on 3 hours. Additionally, I used the Sleep Cycle app to monitor my sleep phases. Unfortunately, this morning my alarm did not go off since the Brainwave app was using the audio output. I woke up by myself at 6.44 am after a total sleep time of 3h 30m. Apparently, I was already awake at 6 am, but I did not know.


For tonight, I will use the Brainwave app on my iPad and the Sleep Cycle app on my iPhone, so I can use two audio sources. During the next days, I will alternate between sleeping with and without the brainwaves to figure out a difference.

The huge difference this morning was, that I did not feel tired at all. I woke up and did not have to force myself to get up. I took a shower and was just feeling great. The rest of the day was pretty unspectacular. I took my naps at the scheduled times, could fall asleep immediately and finally went to bed at 3 am. My tiredness at night is also becoming less. Let's see, what the next day brings...

Day 3 - Sleep Cycle alarm clock

The morning started with the same story: it's still hard to get out of bed right after the core sleep. More interestingly, I used an iPhone app called Sleep Cycle to monitor my sleep.
It tracks which phase of sleep you're in by the amount of movement you make when you're sleeping. In the image below you can see a graph of sleep phase vs. the time of the day (a.m., of course)



It's kind of hard to see but at time 0, I fell into deep sleep immediately and remained in deep sleep until I was awake around 6 am (which I don't remember being awake) but then I fell back to sleep until it was time to wake up at 7 am. I think the immediate plunge into deep sleep was due to the immense sleepiness I felt right around 3.30 am. I managed to pull through and went right to sleep at 4 am. So if you want to monitor your sleep, you should definitely get this app. It also wakes you up during a certain timeframe when you're in the awake phase so that you don't have a hard time waking up. So if you set your alarm to 7 am but allow a 30 min timeframe, it will wake you up at 6.45 am if you happen to be in the awake phase around that time.

So, Thomas forgot to mention in the previous post that due to our extended hours, we have to eat an additional meal during dinner. We also started eating breakfast, which we usually skipped during the 'normal' days (ah, normal days....I do not miss you quite yet). For those who don't know me, I could use a couple of pounds so having this extra meal might actually benefit me. :)

Okay, so later during the day, I encountered a problem with my nap time in that I had to extend them to a later time due to scheduling conflicts. Instead of sleeping at 11 am and 5.30 pm, I went to sleep at 1 pm and 7 pm. As described before by fellow Everyman sleepers, the hour adjustment to your nap time barely affects your sleep. I did not feel extra sleepy that day but continued to function as a normal human being.

Day 2 - Discovering brainwaves

I also had a hard time staying awake last night and I made it till 3 am. I decided to take my core sleep between 3 am and 6 am since the recreation center opens at 6.30 am. I wanted to work out, then have breakfast and then go to work.

When I woke up after 3 hours of sleep, I really had to force myself to get up. I felt tired and just wanted to go back to bed. Of course, I didn't, but got ready for exercising. I biked to the recreation center and as soon as I arrived there, I was feeling great. It felt like I slept the whole night and I was not tired anymore and did not yawn at all. I was able to work out and did not feel weak. Since this was my first workout after half a year, it was clear that my muscles would be sore for at least a day or two.

After more then 1 hour of workout, I went back home and had a healthy breakfast. In general, we decided to eat more healthy food, since the first days or maybe even weeks would be hard for our bodies. We stocked up on vegetables and fruit and also monitored the amount of water we drink per day to make sure we get at least 3 liters.

Starting with my arrival in the office at 9 am the rest of the day just felt amazing. I was awake and alert all day and took my naps at 11 am because I had a meeting at noon, then at 4 pm and at 10 pm. When waking up from a nap, it was really hard to tell if I actually slept. I knew, that I was dreaming and after my first nap I remembered 5 different scenes from my dreams. When I was sleeping monophasically I could only rarely remember what I dreamed. After the nap I felt rested and alert again, even though I wasn't sure if I actually fell asleep. I could concentrate on my work and did not feel sleepy at all.

I noticed one very interesting thing, when I was reading a scientific book in the afternoon. Usually, when I was a little tired it occasionally happened to me that after reading 3 paragraphs for example, I realized that I didn't know what I just read. I had to read the passage again to finally absorb it. Now, I read 3 chapters of the book and did not lose track a single time. I absorbed every sentence, had no problems understanding the subject matter and did not have to read a single line twice. I was really surprised and I am going to further observe this during the next days.

When surfing the internet and reading about sleeping again, I stumbled upon a very interesting thing called "binaural beats". The electrical activity of our brain can be very different depending on what we are doing or feeling. Each frequency of the so called brainwaves has a state of mind corresponding to it.The following frequency ranges give a short overview (Source: http://en.wikipedia.org/wiki/Binaural_beats):


Frequency range Name Usually associated with:
> 40 Hz Gamma waves Higher mental activity, including perception, problem solving, fear, and consciousness
13–39 Hz Beta waves Active, busy or anxious thinking and active concentration, arousal, cognition, and or paranoia
7–13 Hz Alpha waves Relaxation (while awake), pre-sleep and pre-wake drowsiness
4–7 Hz Theta waves Dreams, deep meditation/relaxation, REM sleep
< 4 Hz Delta waves Deep dreamless sleep, loss of body awareness

It is possible to stimulate the brainwaves from the outside by sending two different sine waves to the left and right ear, respectively. If these waves have the right frequency difference, the brainwaves will synchronize to this frequency and therefore the brain will be found in the associated state. we found this iPhone app, which is specifically made for power naps:
The app features two different programs, one for the daytime and one for the evening. The daytime program starts with a descending delta wave pattern to induce sleep, followed by a constant delta wave sleep stage. The final stage is a waking sequence that gently introduces higher frequency, ascending beta waves. The evening program lacks the waking sequence and therefore won't be used by us, since we still have to be awake and want to be productive for 5 or 6 more hours after hour evening nap.

From now on, we started napping with headphones on. The difference was huge. I fell asleep after only a few minutes and eventually realized, that I was awake again. I kept my eyes closed and did not get up, since my nap time was not over, yet. After approximately one minute, the brainwave cycle was over and the alarm went off. I got up and I felt just great. The nap felt like a usual 8-hour sleep at night, but with the huge difference, that I did not feel sleepy when waking up. I was already in a state, where I could immediately go back to work and be productive. I was intrigued!

Besides the iPhone app mentioned above, this one might also be of interest:
This app features 25 different brainwave cycles including "Espresso Shot",  "Motivation Boost", "Euphoria" and "Deep Sleep". We tried some of them and they really seem to work. For example late at night, I was really struggling again and tried to stay awake until 3.30 am. At 2 am, I used the "Focused and Alert" cycle and was able to focus on my work again.

For the night, I decided to sleep with headphones again to use the Daytime Power Nap cycle and set the duration to 3 hours. I wanted to figure out, if I could tell a difference between sleeping with and without brainwave entrainment.
