This section examines the concepts of leisure time, recreation, and outdoor recreation within a theoretical framework; subsequently, the effects of Shinrin-Yoku, an outdoor-based recreational activity, on stress are evaluated. Leisure time, as a period of time remaining after obligatory functions and which an individual interprets according to their own preferences, constitutes an important area for supporting rejuvenation and well-being. Recreation, on the other hand, is a general expression of voluntary activities carried out during this time that strengthen the physical, mental, and social integrity of the individual. Outdoor recreation encompasses recreational experiences where the individual directly interacts with the environment, based on interaction with the physical and sensory stimuli offered by the natural environment. Nature walks, climbs, exploratory trips, and similar activities highlight the rejuvenating nature of outdoor recreation. In this context, Shinrin-Yoku is considered a special outdoor recreation practice that prioritizes benefiting from the holistic atmosphere of the natural environment.

Slow-paced walks in a forest environment, sensory awareness practices, and controlled interaction with visual and auditory stimuli constitute the core components of Shinrin-Yoku. Various scientific studies have shown that this interaction with the natural environment reduces stress levels, lowers physiological arousal, and supports mental recovery. Therefore, in conclusion, it can be stated that Shinrin-Yoku has a significant stress-reducing effect on individuals' stress levels. Furthermore, it can be said that Shinrin-Yoku stands out as an effective practice that combines the flexibility provided by leisure time with the rejuvenating nature of recreation, highlighting the healing aspect of the outdoor experience.
