Locked Up Living is a podcast hosted by Dr Naomi Murphy and co-hosted by David Jones, exploring the challenges and solutions within institutional settings, especially prisons and healthcare environments. The show features conversations with a range of experts and thought leaders, aiming to uncover both the harsh realities of institutional life and innovative ways to support growth, wellbeing, and development.
In this episode, neuroscientist Sarah Turner joins the podcast to discuss the interconnectedness of the brain, body, gut, and environmental factors—particularly light—and how these can be leveraged to enhance wellbeing, especially within challenging environments like prisons.
The discussion covers cutting-edge topics such as photobiomodulation (red and near-infrared light therapy), the importance of the microbiome, and accessible ways to improve mental and physical health.
Key Insights
• The Power of Light: Sarah Turner explains how natural light and targeted light therapy can increase brain energy, reduce inflammation, and even improve symptoms of severe conditions like motorneurone disease, based on real case studies.
• The Microbiome and Diet: The podcast stresses the under-appreciated impact of gut health and prison diets on mental health, behaviour, and emotional regulation—highlighting simple, low-cost changes that can yield significant benefits.
• Empowering Agency: Regular wellbeing routines, including exposure to natural light and small dietary adjustments, provide individuals—even those in highly restrictive environments—with a sense of agency and potential improvements in quality of life.
• Accessibility and Solutions: Sarah Turner offers practical strategies for making light and nutrition-based interventions more accessible in institutions, emphasising education, simple environmental changes, and the use of inexpensive tools (like red clothes or flax seeds).
• Research and Integrity: The episode touches on the importance of scientific transparency and collaboration, and the challenges of bringing new wellness technologies to those most in need.
Who Should Listen
• Professionals working in prison, secure care, or institutional environments
• Healthcare practitioners interested in holistic and innovative interventions
• Policy makers focused on wellbeing in constrained settings
