Simply put, all of my problems stem from trying to jam too much into each day. Partly that’s from my having too many ideas. But mostly that’s from insufficient self-awareness to let things go. Over a few decades I’ve steered away from the typical schedule (and it was never anything like a 9-to-5 job.) But I’m still on a strict sleep schedule, with strict light hygiene practices, and no alarm clock. I sleep in utter darkness, and I awake as the room lighting slowly comes up to full brightness—a mimicked sunrise. But I’m still clinging to set times.
Sometimes I break routine by staying out, or up, past my usual bedtime. Sometimes I’m traveling and staying with others. In either case, I don’t seem to have trouble bending my sleep schedule. I’m often the first person to “crash”, but other than that, with a bit of balance-the-total-sleep-time over-sleeping… I feel pretty normal the next day.
All humans, animals, insects and birds have clocks inside, biological devices controlled by genes, proteins and molecular cascades. These inner clocks are connected to the ceaseless yet varying cycle of light and dark caused by the rotation and tilt of our planet. They drive primal physiological, neural and behavioural systems according to a roughly 24-hour cycle, otherwise known as our circadian rhythm, affecting our moods, desires, appetites, sleep patterns, and sense of the passage of time.~ Karen Emslie from, https://aeon.co/essays/why-broken-sleep-is-a-golden-time-for-creativity
Except for how much I can get done. On those “next days” where I’ve been off my rigid sleep times. I get vastly less done, and not just because there are fewer hours in the day when I sleep longer in the morning. In fact, the more I glimpse that other world—went to bed whenever, slept until the right amount of time… and then face a less-productive day. The more I realize, that is the better amount of things to attempt to accomplish: Sleep on a healthy, light-driven cycle, and do half as much in the day.
