The Thinking Practitioner

🎙In this episode, Til Luchau and Whitney Lowe speak with renowned neuroscientist Dr. Stephen Porges, originator of Polyvagal Theory. Together, they explore how our nervous systems respond to cues of safety, how touch can support regulation and connection, and what all this means for bodyworkers and manual therapists.

Dr. Porges shares the latest thinking on co-regulation, trauma, attunement, and the science of feeling safe—along with practical insights for practitioners working with the body.

🎙Grief is not just an emotion—it’s a full-body experience. In this episode, Til Luchau talks with neuroscientist and psychologist Mary-Frances O’Connor, author of The Grieving Body, about how grief changes the brain, affects inflammation, and alters our physiology. They explore how attachment loss rewires the brain, how inflammatory responses shape behavior and mood, and how the body experiences grief via physical sensations.

They also discuss the role of touch, bodywork, and therapeutic presence in supporting people through grief, and together they reflect on the profound connections between grief, the body, and the healing power of human connection.

• 04:30 – Grief and the brain: What happens in the mind-body connection
• 10:45 – Grief is not toxic: A new understanding of pain and loss
• 16:00 – How inflammation shapes behavior and mood in grief
