Nobody talks about blood sugar in the context of creative work. It's not a romantic subject. It doesn't fit the image of the writer sustained by coffee and obsession, the artist too absorbed in the work to think about something as mundane as lunch. The creative mythology we've inherited is largely a mythology of transcendence, of rising above the body's demands in service of the work.

Sometime in the last few centuries, creative work became a sitting activity. The desk, the chair, the fixed position in front of the fixed surface, these became the default image of what serious intellectual and creative work looks like. You sit down to think. You sit down to write. You sit down to compose or design or figure things out. The sitting is so associated with the working that suggesting movement as part of the creative process can sound like a suggestion to not work, to take a break from the real thing.

You've been breathing your entire life without thinking about it, which is mostly a feature rather than a bug. The autonomic nervous system handles the breath so you don't have to, keeping you oxygenated through sleep and stress and everything in between without requiring your conscious participation.

At some point today, without noticing it happened, you probably raised your shoulders toward your ears. Or clenched your jaw. Or held your breath for a moment while reading something difficult. Or gripped your pen or your mouse harder than the task required. Or sat in a position that your spine would object to if it had a voice, which in a sense it does, just not one that speaks loudly until the damage is done.

There's a moment that most creative people recognize, even if they've never named it. You're working on something, a piece of writing, a project, a decision about which direction to take the work, and before you've consciously figured anything out, something in you already knows. A felt sense that something is off, or that this is the right path, or that the sentence you just wrote isn't quite true even though you can't yet explain why.

If you've spent any time in creative work, you've probably had a version of this experience. You sit down to make something and instead of the focused, generative state you were hoping for, you get a low-grade hum of anxiety. Or a restlessness that won't settle. Or a sudden overwhelming need to check your phone, clean something, do anything other than the thing you sat down to do.
