In research going back to James Pennebaker's work in the 1980s, writing honestly about a difficult experience for a short stretch, several days running, is linked to modest but measurable improvements in mood and some physical health markers. It isn't about tidy writing — it's about writing that's actually honest.
What is happening
Pennebaker's original studies had people write about something difficult for fifteen to twenty minutes, several days in a row, with no one reading it back to them. The people who did tended to show, afterward, fewer doctor visits and better mood than a comparison group who wrote about something neutral. The effect is modest, and it doesn't show up after one entry.

Write for yourself, not for a reader.
Because the effect in the research came from honest writing, not polished writing.
A messy paragraph, crossed out and rewritten, no one else ever meant to see it.

Fifteen to twenty minutes tends to be enough.
Because that's roughly the length used across Pennebaker's original studies.
A hand cramping slightly by the last few lines, and the page still full.

It works better across several days than once.
Because the measured benefit came from a short run of days, not a single session.
The same notebook, opened again the next evening without having to be convinced.
4 of 5
Write the hard feeling, not just the facts.
Because the studies found honesty about the feeling mattered more than describing events.
A hand writing "I was furious," plainly, instead of just what happened.

It's a modest lift, not a fix.
Because the measured gains were real but small, not a cure for what's written about.
The same problem on the page the next morning, just a little more workable.
The practice
Set a timer for fifteen minutes and write, by hand or typed, about something that's actually bothering you — not what happened, but what it felt like. Don't worry about grammar or whether it makes sense. Try it again tomorrow before deciding whether it's doing anything.
The page doesn't answer anything. It just gives the feeling somewhere to go.
