The complex medical environment makes doctors face various pressures and challenges. Positive psychology examines the inner positive potential and behavioral motivation of human beings with an appreciative and open vision, and emphasizes that psychology should provide technical support for the physical and mental health and life quality of ordinary people. At present, positive psychology focuses on the study of human positive emotions and experience, positive personality characteristics and positive psychological process, thus making up the deficiency of negative psychology research. In the face of all kinds of negative emotions from the society and medical treatment itself, it is necessary to build a harmonious medical environment with positive psychological stimulation, positive clinical empathy and positive attitude adjustment, so as to promote the development of modern medicine.
