Name it to tame it: why putting feelings into words helps
12 October 2026

You’ve probably felt it: a vague, heavy mood that gets a little lighter the moment you say what it is. “I’m not angry, I’m just tired.” It turns out there’s science behind that relief.
What happens in the brain
In 2007, UCLA researcher Matthew Lieberman and colleagues scanned people’s brains while they looked at pictures of emotional faces. Sometimes participants simply looked. Other times they chose a word to describe the emotion they saw, such as “angry” or “scared”.
Labelling the feeling made a difference. Putting it into words reduced activity in the amygdala, a brain region involved in emotional reactions, and increased activity in a prefrontal region involved in regulating them. The researchers called this affect labelling: naming an emotion can take some of the heat out of it.
It was a small lab study, and looking at photos isn’t the same as living through a hard day. But it fits a pattern seen across many studies of writing and wellbeing: turning feelings into words seems to help us handle them.
Why writing it down helps
Saying a feeling out loud helps. Writing it down adds a few more things:
- It slows you down. Finding the right word means paying attention to what you’re actually feeling.
- It creates distance. Once it’s on the page, it’s something you have, not something you are.
- It builds a record. Over time, you can see that hard days pass, and what tends to help.
Try it in one line
You don’t need a long entry. Next time you write about your day, add one line with a specific feeling word:
- Instead of “bad day”, try “frustrated that the meeting ran late”.
- Instead of “fine”, try “calm, a bit restless in the afternoon”.
- Instead of “great”, try “proud I finally called Ana”.
Specific words are the point. “Stressed” is a start; “worried about Friday’s deadline” is better.
A gentle place to put it
