I read yesterday online about something called polyphasic sleep or something similar. I’d actually heard about it a few years ago, but the article I read yesterday reminded me of it.
The basic idea is that instead of getting all your sleep at night, you take 4 or 5 naps throughout the day. The deprivation of a full chunk of sleep tricks your brain into entering REM sleep more quickly and you get all the rest you need in a combined total of only two hours each day.
I thought about possibly pursuing a less drastic cycle with a core sleeping chunk at night, but only for 4 hours or so with two naps scattered through the day. It’s a heavy undertaking though, with warnings about feeling a bit out of it for a week or so. Can I afford that?
I’m not sure, but if it means I actually get four more hours each day, it might be worth trying.
