When guests return from a stay at a wellness/spa retreat, they may personally know that their physical and mental health has been improved, but the impact of these stays at global wellness retreats has remained largely anecdotal and under-analyzed. A new GWI Initiative, “The WORLD (Wellness Outcomes from Residential Lifestyle Destination) Retreat Study,” chaired by Professor Marc Cohen, professor of Health Sciences, RMIT University, aims to change that. This research project will empirically aggregate and assess the outcomes from wellness retreat stays through a standardized online assessment tool that will measure guests’ depression, stress, mood, sleep, health symptoms, quality of life and cognitive function, etc. before and after the retreat experience. This research will help lead to increased investment and government support for these facilities.
