I take 3 20 minute naps per day. Once at lunch, one after work and one around 10:00 pm. I too believe this builds sleep credit. I only require 3-4 hours sleep at night and feel more rested than ever before sleeping a total of (4-5 hours per day). There is Science that proves gray matter and emotional intelligence increases with sleep credit. I’m not sure what you meant by polyphasic sleep but I guess my schedule would be considered that. You might try and train your brain to nap more frequently and you can have nights like you expressed in this post everyday without accumulating sleep debt.
Sleep Credit - Greg Woods - Occasionally Useful
Sleep appears to be an area of human ‘activity’ which we are still learning about. One observation of sleep is that we can rack up a sleep debt - where we can go a night or two with reduced sleep, and perhaps feel OK for those few days. Eventually the debt must be repaid, or we’ll start falling asleep at the wheel, getting irritable with others etc. Well, I’ve long maintained that I build up sleep credit. My optimum sleep is likely 7 hours, maybe as low as 6. Mrs Woods seems to need at least 8. So we go to bed somewhere in between - which I suspect is doing neither of us any good. I wake up alert early, fail to get up because the bed is a nice place to be. So I fall back to sleep and the alarm then wakes me in some part of the sleep cycle which you probably shouldn’t be woken from. I feel OK, but not as good as I did when I first woke. So after 2 weeks with no really late nights, I seem to build up sleep credit. Last night was one of those nights. In bed at midnight. By 1:15am, it was obvious I wasn’t getting to sleep, so I did the correct thing and got up. I started programming on a Windows Phone app I’ve been struggling to devote time to. I made the best progress in a long time. By 4am I wrapped it up and went to bed. I still wasn’t tired, but tossed and turned until 6am when I did get some sleep - though not much. So in one night my sleep credit has turned into sleep debt. But as long as I don’t give in to the temptation of a post-work nap, or go to bed really early, I should sleep normally for the next week or two. Maybe I should try polyphasic sleep - though I suspect we’d need separate beds for that! Footnote Sleep is a complex thing. My little ‘sleep credit’ theory could be complete rubbish. Subconscious anxiety, too much caffeine (I admit my body can’t handle caffeine as well these days), a slightly disturbed sleep environment could all have contributed to last nights sleep deprivation. Though the sleepless nights do seem to follow a vague pattern.
