This practical book introduces “nature­-based therapy” (NBT) as a newer thera­peutic approach to the treatment of stress­related illnesses. The authors, with many years of experience in the felds of psychosomatics and garden therapy, use NBT as an extension of garden therapy and landscape medi­cine. They present the theoretical foun­dations and justify the use of nature as a therapeutic space. They show how the therapeutic approach can be applied in the felds of stress research, psycho­ neuro­immunology, epigenetics, per­sonality psychology, and lifestyle re­search. In 20 case descriptions they present the use of concrete therapy modules and describe each module with preparatory nature anamnesis, core topics, goals, materials and exercises.
