Influencing the immune system through psychotherapy. The nervous, hormonal, and immune systems influence each other reciprocally – there is now a wealth of evidence supporting this. However, the situation is much more complicated, as both the psyche and social environment also affect the immune system. The diversity of all these interactions forms a complex network that significantly impacts immune activity. Is it possible to specifically influence immune activity through psychological and psychotherapeutic interventions based on this understanding? This is an intriguing question that psychoneuroimmunology answers with a clear yes – and the nuanced responses provided in this book also offer explanatory models for how psychotherapy can help physically ill individuals recover. In the new edition, Schubert explicitly addresses the empirically proven connection that exists.
