Abstract
Pennebaker surveys expressive writing — putting emotional experience into words improves health and immune markers in multiple trials — disclosure reorganises stress.
Pennebaker, J. W. (1997). Psychological Science, 8(3), 162–166. DOI
Key findings
- Writing heals — Structured writing about upsetting events shifts health indices.
- Not vent only — Coherent narrative beats rumination dump — form matters.
- Immune markers — Lab studies show physiological follow-through, not only mood report.
- Storytelling body — Language interfaces with stress biology — words land in tissue.
Limits
Expressive writing trials — mostly student and community samples; effect sizes vary by protocol length and topic. Not a substitute for clinical care when trauma is acute.
Application
When story stays stuck in the body — writing can reorganise emotional experience, not only vent. See Storytelling.
