The concept of User Experience (UX) in design has evolved beyond usability and aesthetics to encompass broader dimensions of emotional, cognitive, and social wellbeing. This paper explores the intersection of UX and wellbeing, proposing a shift in design thinking toward experience-driven, human-centered approaches that support holistic wellbeing. Drawing on interdisciplinary research from psychology, environmental science, human–computer interaction, and architecture, the study highlights the diverse methods and tools used to assess wellbeing, including self-reports, physiological measures, and digital technologies. It also examines how design can influence wellbeing through user-centered, positive, and ethical frameworks, addressing key challenges in conceptual clarity, methodological rigor, and practical implementation. The paper concludes with a research agenda focused on integrating wellbeing into UX design through new assessment methods, cross-disciplinary collaboration, and development of culturally sensitive, sustainable design principles. By aligning UX with wellbeing, the study aims to guide future research and practice in creating more meaningful, engaging, and health-promoting user experiences.
