Norman Cousins' personal experience with illness and healing led him to emphasize the importance of addressing the psychological and social aspects of health in addition to the biomedical. He believed in the biopsychosocial model of healthcare, which takes a holistic approach to care and treats the patient as a whole person rather than just treating their physical symptoms. While he did advocate for integrative medicine and the use of alternative therapies alongside traditional medicine, he did not claim that alternative medicine cured all autoimmune diseases or that positive emotions were always superior to traditional medicine.
