Therapeutic Lifestyle Changes (TLCs) identified in "8 Ways to Wellbeing for Recovering People," are an underutilized, but profoundly effective treatment for optimizing mental health and supporting recovery from most psychiatric issues, such as addiction, anxiety, depression, eating disorders and trauma. In addition, they are an effective intervention for relapse prevention. Based on the exhaustive research of Roger Walsh, M.D., Ph.D. at the University of CA at Irvine, these TLCs described and amplified in this workshop, can serve as core curriculum for inpatient or outpatient programs, as well as individual use. Why "lifestyle changes?" Because research shows that TLCs, such as changing ones diet, getting regular exercise, relaxation, healthy recreation, time outdoors in nature, fostering supportive relationships, spiritual practice and service to others can be enormously beneficial for optimizing mental and physical health and wellbeing.TLCs are not the whole answer. Nothing is. They are a proven modality in addiction treatment.
