Biphasic Sleep: Post Mortem

Posted by Ibrahim On July - 6 - 2009

sleeping Biphasic Sleep: Post Mortem

I finished the Biphasic Sleep Experiment 4 days ago.  I have since slept 2 nights monophasic and 2 more nights biphasic.  Here is what I think after having experienced both.

After 2 days of monophasic my midday lul (around 1:30 - 3 pm) decreased.  I wasn’t as tired, and after getting up and moving a bit it seemed almost non-existant, as compared to biphasic.  But without my afternoon/evening nap, I got tired much earlier than usual, around 1 am instead of 4 am.  And instead of waking up early like I always did during biphasic (without trouble) I slept in and ended up sleeping for about 9 hours each day.  I switched back to biphasic sleep and again woke up easily.

Biphasic is great for people who have a million things going on and need to get things done.  I’ve found that transitioning between biphasic and monophasic isn’t difficult after the initial transition.  I usually just add an hour and a half of extra sleep the first night of the transition.

Biphasic Sleep: Days 28, 29, and 30

Posted by Ibrahim On July - 2 - 2009

biphasic daily Biphasic Sleep: Days 28, 29, and 30This morning ended the last day of the biphasic experiment.  The last few days were not only easy, they didn’t feel like an experiment at all.  It has become a lifestyle habit, one that I will find hard to give up (should I choose to).  I have been more productive these last 30 days, and I have even watched a little tv or played video games throughout the 30 days (something I rarely ever do, since  I have no time).

My diet has been stable throughout the entire experiment, although the times which I became hungry were a little different.  I’m not hungry for breakfast till about 10:30 am, lunch around 3, and dinner around 9-10pm.  Usually I also eat a smaller meal around 1-2 am, and snack in between each meal of the day.

Biphasic Sleep: Days 22-27

Posted by Ibrahim On June - 29 - 2009

biphasic daily Biphasic Sleep: Days 22 27So the days are now routine, I have no problems going to sleep when I need to or waking up.  My midday ‘lul’ is something I’m still adjusting to, but I’ve found that if I’m eating during that time I tend to have a better time staying awake.  The hardest part of the experiment so far has been getting out of bed on the weekends at scheduled time.  It’s not that I’m too tired, but there is nothing forcing me out of bed, and my bed is just so warm and comfy.

Biphasic Sleep: Days 15 & 16

Posted by Ibrahim On June - 18 - 2009

biphasic daily Biphasic Sleep: Days 15 & 16This morning ended day 16 of the biphasic sleep experiment.  Things are becoming pretty routine now.  I haven’t had many problems the last few days, other than changing the time of my 1.5 hour nap.

It turns out that waking up at 7am for work, then having summer class from 12 pm - 3 pm is pretty exhausting business.  The last 2 days I came home around 4 pm and slept till 5:30 pm.  Upon waking I stayed up till 4 am before sleeping again.  This schedule seems to fit better, at least while in summer school.  We’ll see how I adapt after it’s over (assuming I’m still doing biphasic).

Biphasic Sleep: Days 10 & 11

Posted by Ibrahim On June - 12 - 2009

biphasic10 Biphasic Sleep: Days 10 & 11This morning closes day 11 of my biphasic sleep experiment.  These last few days have started to feel normal.  I’m really enjoying the experiment.  I’m getting things done, I have time to do fun things like work out, play sports, play video games, read extracurricularly, and write about it all.  Sleep? Who needs it.

I slept a total of 6 hours on day 10, I went to sleep a little early after exhausting myself playing basketball for a few hours.  Yesterday, though, was 4.5 hours.  I absolutely love it.  I don’t think I”m going to have any trouble finishing the 30 days of this experiment.  It already feels routine, and my friends and family are starting to realize that I’m sticking with it.

Biphasic Sleep: Days 8 & 9

Posted by Ibrahim On June - 10 - 2009

biphasic89 Biphasic Sleep: Days 8 & 9This morning ended day 9 of the experiment.  I can honestly say that while I’m not necessarily tired all the time, I do want to sleep all the time.  I really miss the warm, cozy feeling of curling up under a blanket and drifting of to dream land.  That being said, my productivity has probably doubled due to biphasic sleep.

Yesterday evening I worked out pretty hard.  To make up for the extra rest I would need I went to sleep 1.5 hours earlier, at 2:30 am. Read the rest of this entry »

Biphasic Sleep: Day 7

Posted by Ibrahim On June - 7 - 2009

biphasic7 Biphasic Sleep: Day 7This morning ended day 7 of my biphasic sleep experiment.  This means I’ve made it through the first of 4 weeks.  Here are a few observations I’ve made so far.

  • It’s easy to get out of bed Monday - Friday when I work at 8 am;  Saturday and Sunday were both more difficult, since there is nothing immediately forcing me out of bed.
  • I definitely enjoy the extra productivity, but it’s almost becoming difficult to fill all the extra time.  That’s why I’ve taken on so many new projects, including my newest, contributing for LifeHack.org. Read the rest of this entry »

Biphasic Sleep: Day 6

biphasic6 Biphasic Sleep: Day 6

This morning ended day 6. I slept in 2 hours more than I planned, but this was to be expected since I didn’t commit to the 90 minute nap yesterday evening. I went out with an old friend and just never got the chance. Still I’m feeling great about the experiment so far. I’m getting a lot of stuff done. Read the rest of this entry »
