Write it out: expressive writing beats venting for stress
September 29, 2026 · 18 min read
Huberman details James Pennebaker's four-session expressive writing protocol and its benefits for anxiety, sleep and immunity, Ethan Kross explains why venting often backfires while expressive writing helps, Huberman's grief episode uses emotional writing, and Lori Gottlieb warns that unexpressed emotion becomes illness. Structured writing gives emotion an outlet without the rumination that venting can feed.
The rules, numbers and steps worth keeping in front of you.
- James Pennebaker's protocol, as Andrew Huberman describes it: four sessions of 15 to 30 minutes on the same difficult experience.
- Schedule: four consecutive days or once a week for four weeks; then you are done.
- Write continuously, ignore grammar and spelling, and write only for yourself.
- Include the facts, your emotions then and now, and any links to your past, present or future.
- Allow recovery time, about 10 minutes after 20 of writing, and do not write just before bed.
- Keep it private; share only with a mental health professional.
- Reported benefits include less chronic anxiety and insomnia; it is not a cure for depression or PTSD.
- Ethan Kross: writing imposes sentence structure on looping thoughts.
- Kross: venting builds bonds but keeps you stuck if the listener only validates you.
- Kross's shorter variant: 15 to 20 minutes a day for one to three days.
- Lori Gottlieb: suppressed feelings resurface as anxiety, insomnia, numbness and depression.
- Gottlieb: seek wise compassion, truth with kindness, not blind agreement.
- Grief writing helped only some people in a small, preliminary study (Huberman).
- If it overwhelms you, stop; with trauma, depression, PTSD or complicated grief, work with a therapist or doctor.
