The Journaling Method That Changes the Brain: Science, Trauma & Healing
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
In this episode of Talk Time, clinical hypnotherapist Meredith McCarthy is joined by colleague Teresa Saunders to explore a powerful, research-based approach to journaling that goes far beyond everyday reflection.
The conversation focuses on expressive writing, a structured form of journaling developed by psychologist Dr James Pennebaker and more recently discussed by neuroscientist Andrew Huberman. Research shows this method can support emotional processing, language shifts, and improved psychological and physical wellbeing when used appropriately.
Rather than journaling about daily events, expressive writing involves short, focused writing sessions where people write continuously and privately about emotionally significant experiences — without concern for grammar, structure, or being read by anyone else.
In this episode, we explore:
- What expressive writing is and how it differs from traditional journaling
- Why 15–20 minutes of writing can support meaningful change
- How language patterns shift as emotional processing occurs
- The role of honesty and privacy in the healing process
- Important safety considerations when journaling around trauma
- How this approach can complement therapeutic work
This episode may be helpful if you’re interested in self-reflection, evidence-based wellbeing tools, or understanding how language and the brain interact in healing.
