Ifs (Internal Family Systems) Health Therapy

Many chronic health conditions—from inflammation and digestive disorders to metabolic syndrome and autoimmune diseases—are increasingly linked to the lasting effects of chronic stress and trauma. But how do these experiences become embedded in the body, and how can we help?

In IFS (Internal Family Systems) Health Therapy , Nancy Sowell, in collaboration with Martha Sweezy and IFS founder Richard Schwartz, draws upon thirty years of clinical practice and behavioral medicine experience to present a groundbreaking mind-body approach that views protective and vulnerable inner “parts” as key drivers of physical health concerns. From this perspective, relief emerges as clients support these internal parts and release trauma-related burdens.

Through vivid case examples, experiential exercises, and practical tools, clinicians will learn how to use a clear three-phase framework to:

• Understand how trauma and chronic stress contribute to illness
• Conduct an IFS-informed health therapy assessment
• Identify and befriend protective parts that affect physical symptoms
• Help vulnerable parts release trauma-related burdens
• Collaborate with other health professionals to support whole-person care

Adversity can alter a person’s mind and body, but it does not extinguish the Self’s capacity to heal. This book equips you with the tools to support that capacity.
