Biphasic Sleep, Day 6
Well, I overslept this morning for a couple hours, but everything else went well. I consider this a good day, since it's another day that my body's getting used to sleeping in two chunks, and even with the oversleeping my circadian rhythm is shifting to the new schedule.
I've been having trouble getting to sleep quickly in my core sleep, and I've been thinking that I need to add some time to the beginning of each sleep period so that I actually sleep for the right durations in each sleep period. I'm thinking I'll actually keep the sleep periods the same but add a 30-minute block of reading-in-bed time before each of them. This will ensure that I can fall asleep quickly every time. And if I fall asleep early for a sleep period, it won't be as harmful as falling asleep late (falling asleep up to 30 minutes early means I wake up within the first 30 minutes of a new sleep cycle—Stage 1 and 2 sleep—which is much easier than falling asleep up to 30 minutes late and waking up in the last 30 minutes of a sleep cycle—Stage 4 sleep and REM sleep.
I need to post my logs earlier in the day; I've once again passed my scheduled bedtime (doh!). I'll schedule my sleep from 2am to 5am for tonight to stick with the "90-minute multiples" rule (plus, of course, the new 30-minute reading-in-bed period from 1:30am to 2am).
