In the context of "Internet plus", the progress of science and technology has brought more possibilities and new opportunities to the teaching environment and methods. Among them, the development and maturity of virtual reality (VR) technology have brought a new way of teaching to schools, and its role is becoming increasingly apparent, especially in experimental teaching. It can effectively solve the problems of small teaching space, high cost, and low efficiency in traditional teaching. This article establishes a virtual laboratory that can achieve resource sharing and real-time monitoring, enhance interaction, immersion, and experience, thereby enhancing students' learning interest, enhancing the fun of courses, and maximizing the effectiveness of teaching. Therefore, in recent years, many mental health educators have been trying to introduce VR technology into campus mental health education to promote the mental health of college students and their physical and mental health. Based on the above issues, this article explores the impact of digital virtual simulation technology on mental health education for college students. The research results showed that the average scores for evaluation, planning, implementation, evaluation, and total score in the observation group were 30.
