At night, under the covers, your head calls a meeting without your permission. Today's slip of the tongue, tomorrow's schedule, the messages you haven't answered. For this late-night mental meeting, psychology has a classic method that has been in use for nearly 40 years: writing your emotions down on paper, known as "expressive writing." These days it often goes by the trendier name of journaling, but at its core it is an almost disappointingly simple practice — just a notebook and a pen.
The research on "writing" has been tested since the 1980s
The method traces back to a series of experiments the American psychologist James Pennebaker began in the 1980s. The basic format: write continuously for 15 to 20 minutes about an event or emotions that were highly stressful for you. Repeat this three to five times. It is written on the premise that no one will ever see it, so grammar and structure don't matter. According to a 2005 review paper by the Australian researchers Baikie and Wilhelm, many studies have reported that groups who wrote in this format showed improvements in mental and physical health measures compared with groups who wrote about neutral topics. How exactly it works is still debated, but the act of putting what you carry into words and getting it out of your head has held up under decades of replication.
One important caveat: studies report that mood can actually dip right after writing. If you expect the refreshing lift of a diary entry, you will be disappointed. This is the kind of method that works slowly, over a few days.
Your head is a workbench, not a storage room
Why does writing change anything? The explanation that clicks for me is this: the worries in your head are unprocessed files left open. Your head is not a storage room but a workbench, and the more open files there are, the less working space you have. Writing things down is like naming each file and saving it once. It doesn't disappear, but it can be closed. The reason the late-night mental meeting never ends is that nobody is taking minutes — and the notebook takes on that job.
If the sigh-breathing method is an approach from the body's side, this is an approach from the side of words. Any tool works — a notebook, a notes app — but if you do it before bed, paper has the edge. As we wrote in our piece on phones before bed, the screen houses a second culprit that keeps showing you more.
Tonight, hire a minute-taker for 10 minutes
- Before bed, spend 10 to 15 minutes writing down everything in your head. Don't write it neatly. Bullet points or scrawl are fine. The only rule: no one else sees it.
- For each worry, add one line naming the next move. A file that gets as far as "message so-and-so tomorrow" is easier to close.
- Don't force yourself to process anything too heavy. This method is not a cure-all. If writing makes the pain intense and persistent, stop, and turn to a professional — a doctor or a counseling service.
One notebook, one pen. As recovery equipment goes, this is probably about as cheap as it gets.
