Neuro-Inclusive Virtual Reality: A UDL-Based Intervention for Acute Stress and Anxiety Reduction in University Students

Abstract

In the contemporary higher education landscape, university students face escalating levels of academic stress and anxiety, which significantly impair their mental well-being and cognitive performance. Conventional relaxation techniques often fail to provide immediate relief due to the high cognitive effort required for their mastery. This study proposes an innovative intervention through an immersive Virtual Reality (VR) simulator, specifically designed under the principles of Neuroscience and Universal Design for Learning (UDL). The primary objective is to assess the efficacy of this VR tool as an emotional catalyst for acute stress reduction in a university setting. The methodology employed a quasi-experimental pre-test/post-test design with a sample of 34 students exhibiting moderate to severe stress levels. Participants were immersed in a 15-minute session featuring five 3D simulated activities, including diaphragmatic breathing and guided meditation, within forest or indoor environments. Psychometric evaluation was conducted using standardized instruments (BAI, PSS, and DASS-21) before and after the intervention. Statistical analysis, including Shapiro-Wilk and Wilcoxon signed-rank tests, was performed to determine the significance of the findings. Key results demonstrated a statistically significant reduction (p < 0.001) in stress and anxiety scores. Physical symptoms of autonomic arousal, such as muscular tension and tachycardia, showed a marked decrease, suggesting a successful modulation of amygdala activity and the activation of the parasympathetic nervous system. This demonstrates that VR intervention serves as an effective applied tool for rapid emotional stabilization. While limitations regarding sample size and long-term effects persist, the study highlights a dual contribution: a technological advancement in UDL-based software and a practical educational intervention for university wellness departments.
