This study explores the role of wellness design in educational interiors, examining how design elements reduce stress and enhance mental well-being among students. The purpose of this research is to identify specific design strategies - such as biophilic design, user-centered layouts, and the integration of natural light - that contribute to supportive learning environments. Using a mixed-methods approach, the study includes case analysis of schools employing wellness-focused designs, supplemented by surveys that gauge students’ and educators’ experiences within these spaces. Quantitative data focuses on factors like daylighting levels and spatial arrangement, while qualitative responses capture perceptions of comfort and engagement. Results indicate that elements such as natural light, green features, and adaptable spaces contribute significantly to reducing anxiety and fostering a positive mental state. Schools designed with these principles report higher levels of student satisfaction and focus, and feedback suggests that biophilic and user-cantered designs make classrooms feel more inviting and calming. Conclusively, wellness design in schools is shown to play a vital role in supporting mental well-being and stress reduction, offering a practical framework for designers to enhance learning environments effectively.
