What role can psychologist play in supporting the mental health of displaced Ukrainians? Millions of people have had to flee either abroad or to other parts of the country and the implications for mental health are huge – not only in terms of trauma but for those who’ve escaped, the constant anxiety of watching what’s happening back home and worrying about loved ones. Claudia talks to Emily Holmes, Professor of Clinical Neuroscience at Uppsala University, and Clinical Psychologist Professor Marit Sijbrandij of Vue University Amsterdam who have been working to ensure the interventions with the best evidence behind them get used. And we pay a visit to the Dreamachine, an immersive sound and light installation that uses the power of flickering white light to create psychedelic experiences. Will it open a new window into how our brains make sense of the world? We hear from two scientists behind the project - Anil Seth Professor of Cognitive and Computational Neuroscience, University of Sussex and Fiona MacPherson Professor of Philosophy, University of Glasgow Claudia Hammond’s studio guest is Professor of Health Psychology Daryl O’Connor of Leeds University, armed with new research into how deliberately seeking out discomfort can help drive our personal growth Producer Adrian Washbourne
