Health and Sci
Science helps. Especially when you’re doing odd things to your body. You’re putting your health into a canoe on the ocean. Be a model of caution.
Science and Tradition Say No
Recent scientific research leans toward not chopping sleep. I’m not disputing the bulk of their work, and it’s getting bulkier. Deal with their findings and be responsible for your decisions.
Shift work is being studied. Many of us often don’t function as well on a night shift without special accommodations.
Tradition has a point. Normal sleep is 8 hours nightly (give or take), for some reason. Maybe it’s right.
But some of us are outliers. Many creative people do their best work at night. Maybe you’re one.
Body Clock Off
Circadian rhythms are natural. Yours won’t exist. Too bad.
Our wake-and-sleep cycle averages a bit longer than 24 hours. That fudges our habits that rely on Earth’s rotation. But I don’t know if it’s different if you have a critical work burden, just without a daily schedule as long as you get it done in time.
Probably what’s important is not to expect that you’ll be tired at the same time every night. It may shift. Sleep when you need to without too much fear of the clock.
(Technically, circadian rhythms still exist. You’re ignoring them, although you are watching yourself for danger signs (yes?), so it’s okay.)
