Health psychology focuses on the intersection of psychological and physical well-being, exploring how psychological factors such as stress, behavior, social support, and healthcare experience contribute to health outcomes. This field emphasizes two critical areas: the impact of psychological stress on the development of diseases and the promotion of health behaviors to enhance well-being. Health psychologists engage in research and practice aimed at understanding how thoughts and behaviors affect health, developing interventions for chronic disease management, stress reduction, and improving patient-doctor communication.
