The purpose of this study was to investigate the effects of nature-based leisure (NBL) on individuals living with mental health issues (MHI). Through the use of qualitative semi-structured one-on-one interviews participants defined NBL for themselves and explained the effects participating had on them. Approximately thirty minute interviews were recorded then transcribed verbatim for data analysis. The findings included the effects of NBL such as mental benefits, energy release, a way to get out of day to day routines and relationship building as well as the role their mental health issue played in relation to their NBL participation. These findings point to a need for healthcare professionals to assess an individual's level of NBL participation as a factor in diagnosis and treatment. The findings also point to a need for more education surrounding NBL for Therapeutic Recreation Practitioners, in order to integrate more NBL with clients living with MHI.
