Alright, it is now Monday, and that means that I have completed two weeks of my experiment with biphasic sleeping. Although the first week's journal was very optimistic, I definitely felt a change of heart this time around. At the start of this week, I was feeling quite tired and pessimistic with the likelihood of continuing. Towards the end of the week, things were starting to turn around a little bit, but I am still unsure as to which of these approaches is really the best for me.
With a single block of sleep, I generally find that I feel better rested throughout the day. When I say better rested, I equate that to mean that I feel less of the signs that I associate with being tired: sandy feeling around my eyes, a little less focused, less energy than I would normally have.
On the positive note, I really enjoy having the extra time during my day to work on projects and chores, and being up early when there are minimal distractions is really quite nice. An alternative to giving up biphasic sleep is to switch to a habit where I sleep biphasically during the week, and then have two 8 hour blocks for both of the weekend days. This may be enough to provide me with just enough extra sleep to keep things running smoothly.
Without any more pre-amble, here is the journal for the past week:
Week 2
------
Day 8 (Monday)
I'm now into the second week of biphasic sleeping, and woke up at 4:00AM this morning. One thing that I've noticed is that the amount of time it takes for me to mentally get started has reduced over the course of the last week. While a week ago, I was sitting on the couch and needed to do something like working out or video games to get my head started, I woke up this morning, walked into the bathroom, brushed my teeth, and my head was already filled with ideas and thoughts about how I wanted to spend my day and what I would accomplish first.
I walked out to the living room and started working out and completing some tasks on my TODO list in between sets. One thing I've noticed is that there are really two different types of sleep inertia that we typically have to work our way through in the morning. The first comes from waking up in the middle of REM sleep, and I've touched on that briefly already. Put simply, waking up in the middle of your REM cycle is what gives you that extremely groggy feeling upon waking up, and typically leaves you feeling pretty out of it. The second type of inertia comes from not being very consistent with your sleeping schedule. If you get up at 6:00AM one morning, 8:00AM the next morning, and 11:00AM the third morning, your body is going to have a fairly difficult time adjusting to this. The upshot of this type of inertia is that it just takes longer for your metabolism to get into gear. This is due to the fact that after the first morning, your body is going to start training itself to kick things into gear around 6:00AM. The second morning, this causes you to have poor sleep (as your metabolism does not coincide with the time you're getting up). By the third morning, your body is going to be quite confused, and has probably started your metabolism and then put it back to rest by the time you get up at 10:00AM. These are the mornings that we typically get up and reach for the coffee, causing a caffeine and energy level spike, followed by a subsequent crash.
The previous week, I did not have to deal with the first type of inertia, as I was making sure that I was getting up at the end of a sleep cycle. I did, however, have to deal with the second form of inertia, as my body was not yet trained to get things going at 4 in the morning. Along those lines, if you plan to try something like this out (and I do recommend it - I am really liking it), I would strongly suggest planning some kind of physical activity, along with a light snack, first thing upon getting up. The snack and the activity will jolt your metabolism into gear, and help your body recognize that it needs to train itself to start the engine that much sooner.
On the topic of caffeine: I love coffee, and very much enjoy the rush that a couple of cups of java can give me. However, I also recognize that making it a habit is self-defeating; you lose the rush as your body becomes acclimated to the stuff, and you become dependent on it in order to stay awake and avoid headaches. I start my mornings by making a pot of Earl Grey tea (creamy Earl Grey from Specialty Teas on Fort Street actually - I love this stuff), and drinking that as I go through my morning routine. Tea provides a much more balanced and consistent caffeine intake to your system, and will help you ease your body awake as well as avoiding the crash an hour-and-a-half later. After the first week, you will enjoy the process of making tea (which I find a little more interactive than coffee), and appreciate that you are not reliant on coffee first thing in the morning to function.
-Nap-
I've been up from my nap for about three hours. I have cleared off most of my tasks for the day, so I spent the rest of my time re-sorting my Magic cards (this is a task that either has to be done frequently, or takes a long time), reading about GTD and polyphasic sleeping, and brainstorming ideas for a site redesign.
Although I've passed the one week mark, I definitely felt like I was carrying some sleep inertia with me this afternoon. The familiar sense of 'sandiness' that we get around our eyes when we're tired was present for a couple of hours. I had no intention of returning to bed, and didn't want to take in any caffeine to try and remedy that, so I just sat through it. Mind you, this was nothing severe - just something I noticed.
The other thing to correlate with this is the fact that this was the first time that I got up and out of bed as soon as I felt myself naturally wake up. In the past, I have woken up with about 20-30 minutes before my alarm is set to go off. In these cases I have put my head back down and after a few minutes fallen back to sleep. Today, I made the decision to simply get up at this time and start pulling myself together. It's possible that this decision affected the amount of rest that I received and is the reason for this sensation.
Day 9 (Tuesday)
It's getting easier and easier to get up in the morning (although this hasn't been difficult up to this point either). I've started setting aside my clothes to work out in beside the bed so that I don't have to risk waking Bay up when my alarm goes off. One thing that I've noticed is that it can be difficult to read early in the morning. Sitting in a dimly lit room, before the sun has risen, listening to relaxing music and reading a fairly dense paper about the loss of anonymity in our modern society really starts to have an effect. I don't know if I would mark this up as an issue specific to biphasic or not. I have certainly had moments at work in the past where I simply could not get myself to focus on something without an overwhelming urge to close my eyes and sleep.
One thing that is certain is that there is some degree of discipline required to maintain a schedule like the one I am practicing. It would be quite easy fro myself to close my eyes right now and drift back off to sleep. Again, this sort of thing is present with monophasic forms of sleep as well. However, in my case, doing so would probably throw off my body's ability to successfully adapt to a new sleeping habit. In an attempt to put an end to the yawning today, I've shifted from the comfy couch to our dining room table to do my reading, and am now sitting instead of lying down. The little things can make a big difference.
-Nap-
I had a great nap today, and woken up feeling like I'd slept for a while. However, I am still feeling like I have sleep debt hanging over my shoulders, and I am beginning to wonder if my body is in fact getting enough sleep under this new regime, or if I am simply gradually adding increments to the amount of sleep debt that I have accumulated, and will crash at some point in the future.
Today was the first day that I did not immediately get out of bed upon having my alarm go off, and I caught myself closing my eyes and nearly nodding back off. Clearly this is not a successful move to pull off if I want to continue this experiment to its completion.
Although I very much like rising early and having an extra two hours everyday, I am not willing to sacrifice feeling well rested for those things. This is obviously quite a contrast to how I felt on Sunday, but that's okay - that's precisely why I'm conducting this experiment.
Day 10 (Wednesday)
This marks the second day where I've gotten up and felt like I'm carrying around sleep debt with me. It's nothing that I can't work through or deal with, but I don't like it. Feeling sleepy sucks, feeling well rested rules. While I felt in pretty good shape after my initial bout of weight-lifting and dancing, it is now 11:00AM and I'm once again getting the now familiar sandy feeling around my eyes. I fear this may represent the beginning of the end of this experiment, if things don't begin to improve.
Day 11 (Thursday)
I feel pretty good today (at least at 6:00, after getting up at 4:00), so things are nothing if not inconsistent at this point. Tuesday and Wednesday mark the low point so far for this experiment, but we will have to see how I feel in 5 hours, as 11:00AM has been when I have hit the low point for each of the those days, as well as around 3:00PM.
One thing I do very much enjoy with this schedule is that I get the opportunity to get up and practice dancing for at least an hour every day. This is a non-trivial amount of time to be able to devote to something that I care about. Once school starts, it's entirely possible that studying will have to take that place. One thing that I am definitely wary of is how difficult it can be to study when you feel tired. If I cannot get my energy levels to the right place, I will not be able to use this time in the morning effectively, at least in this regard.
Day 12 (Friday)
Fairly uneventful today. Waking up from a nap is still annoying - damn greasy face. Otherwise the schedule seems to have taken. I felt myself fighting getting up at 3:30 today. I'm not sure if that's due to sleep debt, or simply feeling lazy. I'm going away to Hornby Island with Bay, Ben, and Ashley for the weekend, so this will be another good test to see how the schedule works in this context. The other option is that I simply sleep regularly, and then try to resume on Monday. I'll see how I feel.
Day 13 and 14 (Saturday and Sunday)
As mentioned before, we went to Hornby island for the weekend. However, contrary to what I had originally planned, I decided that I would switch back to a monophasic block of sleep for 8 hours each night once we got there. The reasoning behind this was that the cabin was small and it would be kind of weird getting up and working for five hours before anyone else was up, and I would be running the risk of waking our hosts, which I felt would be pretty obnoxious. I also knew that we would be partying while we were there, and potentially staying up late. Although I have managed both of these last two things on biphasic sleep schedule, it just felt like it would be a bit too much of an effort for a trip that was meant to be a break, both physically and mentally.
I had no problems falling asleep and waking up both nights and mornings. When I got home Sunday night, I felt that I was starting to come down with a cold, and so I opted to stick with a single block of sleep Sunday night as well. It is now Monday, and I feel fine. I also feel less tired than I have with biphasic sleeping as of late. I intend to revert to a biphasic schedule for the rest of this week and then determine how I feel about continuing the schedule or switching back to monophasic full-time.
