Mark Christie

Dr. Mark Christie is a Senior Lecturer in Sport Development at the University of Cumbria, UK, specializing in green exercise, open water swimming, and therapeutic horticulture. His research spans mental health recovery, public health initiatives, and nature-based interventions for diverse populations, including corporate employees, older adults, and individuals with mental ill-health.

Christie’s 15 most recent publications highlight trends in blue space benefits (open water swimming), green exercise (gardening, woodland activities), and conservation-based health programs. Key themes include psychological restoration, social prescribing, and barriers to nature engagement (e.g., water pollution, accessibility).

His work has been featured in podcasts, webinars, and collaborations with the National Institute for Health and Care Research (NIHR). Christie’s studies inform health practitioners, facility operators, and policymakers on optimizing therapeutic outdoor activities. Notable projects include the 'Cold Water Warriors' swimming group and the 'Digging Deep' doctoral thesis, which proposes a green transformative ripple effect model.
