Recent research has identified Shinrin-Yoku (SY), a Japanese term meaning relaxing in nature to improve health, as an efficacious integrative practice to improve humans' physiological and psychological health and well-being. Nature Therapy (NT), also coined as Ecotherapy, includes a breadth of treatments to improve individuals' health in outdoor settings and it, too, has been noted to have beneficial health outcomes. However, research regarding the inter-relationship between SY/NT and human spirituality is limited. The present study undertakes a scoping review on the inter-relationship between SY/NT and human spirituality to determine the extent spirituality research has been conducted. Conceptual frameworks, provision of key definitions and the integrative health outcomes associated with SY/NT and spirituality were highlighted.
