Healing doesn't just happen through thinking — it unfolds as you learn to be with your body.

If you're constantly anxious, overwhelmed, or exhausted, your nervous system might be trying to tell you something.

The Somatic Workbook for Nervous System Regulation and Anxiety Management helps you move beyond just talking about your struggles—  and starts healing them in your body.

This is so much more than a workbook—it's a powerful toolkit that provides both immediate and long-term relief from anxiety. It’s an instant classic, a must-read for anyone who suffers with anxiety and trauma. Every page was vital—page after page of unique stories and personal examples, enlightening explanations based on medical science, actionable exercises that I truly wanted to do, and even visual aids that helped immediately clarify and simplify a very complex issue into a clear path forward. By the time I finished the workbook, I knew I was holding a resource that I would recommend again and again to every patient who suffers with anxiety. Thank you, Dr. Harkess, for the best book on anxiety I have ever read.

Dr Kaitlin N. Harkess, PhD, is the author of The Somatic Workbook for Nervous System Regulation and Anxiety Management (PESI Publishing, October 2025), host of the Wisdom for Wellbeing podcast, and founder of holistic therapy practice Wisdom for Wellbeing. A Clinical Psychologist and long-time yoga and meditation teacher, Kaitlin has helped hundreds of individuals experiencing anxiety, overwhelm and burnout reconnect with their bodies and build resilience through integrative, evidence-informed practices. 

Kaitlin’s pioneering research was the first to examine how yoga impacts stress and mental health at an epigenetic level  (the science of how lifestyle affects gene expression), and she continues to advance the field as a Titleholder at the University of Adelaide’s School of Psychology. Kaitlin also convenes the Australian Psychological Society’s Yoga and Psychology Interest Group and regularly trains clinicians in somatic psychology. 

Based on Kaurna Land in Adelaide, Kaitlin balances her professional work with coastal walks, family life, and a love of the outdoors. Originally from the Canadian Rockies, hiking remains as essential to her wellbeing as her yoga practice.
