Measurable Benefits
Decades of research have explored the connection between writing, reflection and our mental and physical wellbeing. Here, we break down what the research says and why it matters.
Writing can help us process difficult experiences and better understand what we are feeling.
Research has explored how expressive writing may support stress, sleep and physical health.
Practices like gratitude journaling have been linked to improved mood, optimism and wellbeing.
A randomised clinical trial of 1,337 adults asked participants to write daily gratitude lists for 14 days. The gratitude group showed improvements in positive affect, subjective happiness and life satisfaction, alongside reductions in negative affect and depressive symptoms.
In an experimental study, participants who completed a personal values affirmation exercise before a laboratory stressor showed significantly lower cortisol responses than the control group. The research suggests that reflecting on personally important values can influence both psychological and physiological responses to stress.
A controlled study comparing different forms of journaling found that participants who wrote about both the thoughts and emotions surrounding stressful experiences showed greater cognitive processing and awareness of positive outcomes than comparison groups.
