Virtual reality (VR) is increasingly being integrated into clinical healthcare as a multifunctional technology, serving both as an advanced training platform for clinicians and nurses and as a non-pharmacological intervention for pain, phobias, and psychosocial conditions. Defined as an immersive, ultra-realistic, computer-generated environment, VR offers a unique combination of realism and customization, all within a controlled space. Its application in clinical training is rapidly expanding, often outperforming traditional instructional methods. In addition to clinical training, VR has demonstrated potential as a non-pharmacological intervention across diverse patient populations, including individuals with severe burns, those with diagnosed psychological disorders, those undergoing hemodialysis and cancer treatment, and patients. Widespread clinical adoption has been hindered by small sample sizes, lack of rigorous, theory-driven frameworks, insufficient user-centered designs, and the challenges posed by rapidly evolving technology. The lack of high-quality evidence and large-scale clinical trials continue to limit the integration of VR into routine clinical care. This paper evaluates the current state of evidence supporting VR as a clinical tool, incorporating lessons from pilot trials conducted by our team and others, and aims to address ethical and equity-related considerations in patient care. We also examine the applications of VR in patient health education, emphasizing its potential to improve disease understanding, support self-management, and encourage healthy behaviors. The paper concludes with future directions, including the integration of artificial intelligence to enable personalized, patient-centered VR experiences and to support broader adoption in clinical practice.
