What acts
Work on expressive writing — putting a difficult experience into words — shows effects on sleep, mood and even some physiological markers, across protocols of only a few sessions.
The best-supported hypothesis is that putting something into words imposes a narrative structure: a beginning, a middle, an end. What stays as images and sensations loops; what becomes a story stops demanding attention.
Three formats
The dump. Write what occupies you, without rereading, without style, for five minutes. Close the notebook and do not return.
Three lines. Three things from the day — not necessarily positive, but precise. Precision is what works: "the sun on the wall at seven" acts where "a good day" does not.
Tomorrow's list. Writing what must be done shortens time to sleep — the mind stops rehearsing in order not to forget.
Writing at length about a pain without ever ordering it can sustain rather than ease it. If writing brings you back to the same point every night with nothing moving, a notebook is not what you need.
The format that holds
Three lines, paper rather than screen, notebook on the bedside table — friction decides more than intention. And never catch up: a missed night is not a debt.
our piece on rituals sets out the three elements that make a ritual hold.
