Write for 10 minutes about what matters most to you
People who wrote about a value that matters to them had a smaller stress hormone rise during a stressful speech.
Before giving a speech to unsmiling evaluators in a lab at UCLA, some students first spent a few minutes writing about a value that mattered to them. When the speech came, their cortisol, a hormone the body releases under stress, rose less than in students who wrote about something less personal. This habit borrows that exercise: one short page about what you care about, once a week and before the days you dread.
What it helps with
Stress before big events
People who wrote about a value that matters to them had a smaller stress hormone rise during a stressful speech.
Performing under pressure
A short values-writing exercise was linked to better grades for students facing negative stereotypes, though later studies found smaller effects.
Ignoring health advice
Writing about your values makes people somewhat more open to health advice and more likely to plan changes.
Key facts
- 1In a UCLA lab study, students who wrote about a personal value had a smaller cortisol rise during a stressful speech task.
- 2A short values-writing exercise in a US middle school was linked to better grades for Black students who were facing negative stereotypes.
- 3A 2015 meta-analysis found self-affirmation made people somewhat more open to health messages, with small effects on actual behavior.
- 4Several later, larger studies of values affirmation in schools found smaller effects than the early trials, or none.
Why a page about your values helps
Stress often grows when one test, meeting or mistake starts to feel like a verdict on your whole self. Psychologists call this exercise values affirmation, or self-affirmation: you pick something you care about, like family, humor or honesty, and write about why it matters. It reminds you that your worth rests on more than the thing in front of you. The whole habit fits in four words: one value, one page.
How the writing works
You choose one value, then describe a time it shaped what you did or who you were. Writing tends to work better than just thinking about it, because a page asks for real details. The value doesn't need to connect to the stressful event, and in many studies it was unrelated on purpose. Researchers think the exercise widens your view, so a threat takes up a smaller share of how you see yourself. That part is still a theory, since the studies measured results and could not observe the shift itself.
What the research found
In the 2005 UCLA study, the students who affirmed a value showed a smaller cortisol response to the speech task than the comparison group. In a 2006 trial at a US middle school, students wrote about their values a few times early in the school year. Black students who did the exercise earned better grades that term, and the gap with their white classmates narrowed. A 2015 meta-analysis, which pools the results of many studies, found that affirmation made people a little more open to health advice and more likely to plan changes, with small effects on behavior.
The limits matter here. Much of this research involved students or short lab tasks, and some large later attempts to repeat the school results found smaller effects or none at all. Treat this habit as a modest, low-cost help for pressured moments, and expect no transformation.
Making it stick
Pick a regular slot when the week ahead comes into view, like Sunday after dinner. Add an extra page the night before a hard day: an interview, an exam, a difficult conversation. Ten minutes a week adds up to under nine hours a year. You don't need to do it every day: studies used it a few times, timed before pressure, and there is no sign that writing more often works better. On a rough week, three minutes and three honest sentences still count.
Keep the notebook somewhere visible, since a notebook tucked under the takeaway menus has a way of staying there until spring. When Sunday comes round, one value, one page is all you need to keep. Over time you become someone who knows what they stand for before the week begins. If stress, worry or low mood lasts more than a couple of weeks or gets in the way of daily life, talk to a doctor or a therapist. Which value would you write about before the hardest day on your calendar this month?
Action steps
- 1Choose one value. Pick it from a short list such as family, friendship, creativity, faith, health, humor or independence, and write it at the top of a blank page.
- 2Write for 10 minutes about why it matters. After dinner on Sunday, describe a moment when this value guided you, and add a page the night before any day you dread.
- 3Keep the notebook in sight. Leave it on your bedside table or desk, and choose a different value now and then so the writing stays fresh.
Suggested routines
- Everyday stress
Breathe slowly for 5 minutes
Breathing exercises are linked to small to moderate drops in stress.
- Anxiety
Meditate for 10 minutes every morning
Trials show mindfulness meditation programs reduce anxiety.
- Constant worrying
Rewrite one worrying thought a day in balanced words
Rethinking a situation in fairer terms is linked to less anxiety, while dwelling on it is linked to more.
