Experimental Art through a Light–Colour–Sound Exhibition Simulating Nature for Stress Reduction among University Students

Stress remains a critical concern among undergraduates, and psychological research indicates that exposure to natural stimuli—light, colour, and sound—can significantly alleviate perceived stress. This study created an experimental light–colour–sound exhibition featuring motion-graphic visuals that emulate natural environments and complementary ambient soundscapes. Its objectives were (1) to evaluate the exhibition’s effect on students’ stress levels and (2) to examine visitor satisfaction, thereby offering a new perspective on artbased therapy within higher-education settings. Thirty undergraduate students majoring in Medical and Science Media (Years 1–3) participated. Perceived Stress Scale-10 (PSS-10) scores were recorded immediately before entry and visitor-satisfaction ratings were collected upon exit. Descriptive analysis showed that, prior to the exhibition, most participants exhibited moderate stress (n = 23), followed by high (n = 6) and low (n = 1) stress levels. Post-exhibition data revealed a statistically significant reduction in PSS-10 scores, accompanied by self-reported relaxation. Natural sound elements were particularly well received. Mean satisfaction with the overall experience was 4.16 out of 5 (“high”), while the aggregated exhibition-quality score averaged 4.4 out of 5. These findings suggest that a nature-inspired light–colour–sound installation can serve as an effective, art-based intervention for short-term stress reduction among university students and holds promise for broader application within academic institutions.
