Beyond Rest: Nature Tourism and its Measurable Effect on Mental Well-Being Through the Reduction of Depression, Anxiety and Stress

Recent studies have underscored the importance of tourism in enhancing individuals' mental well-being through engagement with nature. This article examines the impact of nature-based tourism on alleviating symptoms of depression, anxiety, and stress among a group of 67 university students who exhibited extremely severe levels of these disorders. Participants were assessed both before and after a nature tourism experience in the Tinajillas - Río Gualaceño Protected Forest, Ecuador. Mental health changes were evaluated using the DASS-21 scale, with assessments conducted pre- and post-activity, revealing significant reductions in depression, anxiety, and stress levels, with large and clinically relevant effect sizes. However, a six-month follow-up indicated that these long-term benefits diminished and no longer held clinical significance, suggesting the need for more frequent interventions to sustain positive effects. The study concludes that nature-based tourism serves as an effective non-pharmacological intervention for improving mental well-being in the short term, although its sustainability requires continuous interaction with nature. These findings provide empirical support for nature-based tourism as a mental health strategy and highlight the importance of integrating it into public health policies and tourism management strategies.
