Art therapy, with painting as its central modality, has garnered substantial em-piri-cal support as an effective intervention for a spectrum of psychological dis-orders. This comprehensive paper delves into the multifaceted mechanisms through which the act of painting facilitates mental health recovery and pro-motes overall well-being. By synthesizing perspectives from clinical psychology, neuroscience, sensory integration theory, and aesthetics, we propose a novel integrated frame-work that elucidates how painting engages cognitive, emo-tional, sensory, and so-cial processes. A systematic and extensive review of em-pirical literature from 2000 to 2024 robustly supports the efficacy of structured and unstructured paint-ing interventions in significantly alleviating symptoms of depression, anxiety, post-traumatic stress disorder (PTSD), and enhancing emotional regulation, self-concept, and resilience. The paper argues that paint-ing serves as a powerful non-verbal medium for externalizing and processing complex emotions, facilitat-ing cognitive restructuring, accessing pre-verbal trauma memories, and fostering a profound sense of agency and accomplish-ment. Furthermore, it explores the neu-robiological underpinnings, including the role of the default mode network (DMN), stress hormone regulation, and neural plasticity. The conclusion empha-sizes the transformative potential of integrating painting into mainstream thera-peutic practices while acknowledg-ing limitations in current research methodolo-gies. The paper culminates with strong recommendations for future research direc-tions, including the stand-ardization of evidence-based protocols, longitudinal studies, the exploration of cross-cultural applications, and the investigation of digital painting's therapeu-tic efficacy.
