Background:
Nature-based interventions (NBIs) benefit human well-being, but clinical trials comparing different NBIs in various natural environments are scarce.
Objective:
To evaluate the efficacy of a multicomponent nature-based intervention (MNBI) in comparison to control group (classical forest bathing).
Primary Outcome:
well-being; Secondary outcomes: vitality, happiness, connection, and engagement with nature across urban, peri-urban, and rural areas.
Methods:
Randomized clinical trial with 486 participants between October/2022 and June/2023, from five natural areas in Southeast and Southern/Brazil. Well-being was assessed immediately before the activity and 30 days after, and secondary outcomes immediately before, immediately after and 30 days after. The data analyses considered a 95 % confidence interval and p-values < 0.05.
Results:
The main hypothesis was confirmed, well-being levels of MNBI group were significantly improved, especially in peri-urban areas (p = 0.036). Both groups increased vitality (p < 0.001), but MNBI was more effective overall (p = 0.038), especially in urban areas (p = 0.020). Happiness increased in both groups (p = 0.001), but MNBI participants maintained higher levels 30 days post-intervention (p = 0.010). Nature connection increased significantly in both groups (p < 0.001) but remained higher in MNBI after 30 days (p = 0.021), especially in peri-urban areas (p = 0.034). While both groups reported calm and relaxation, MNBI uniquely fostered learning, knowledge, and contemplation.
Conclusions:
MNBI was more effective than classical forest bathing in improving well-being, nature connection and pro-environmental behaviors, particularly in peri-urban settings, expanding the potential of NBIs for well-being promotion.

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
