Exercise is often framed as a way to get fit, but what if its biggest benefits are happening in your brain? In this episode of Change Your Mind, Health Journalists Cat de Lange and Helen Thomson explore why movement matters for our mood and long-term brain health, and why making exercise part of everyday life can feel like such a challenge. Joining them is Brendon Stubbs, a leading researcher in physical activity and mental health. Together, they look at what science is beginning to reveal about exercise and the brain, whether some kinds of movement might be better than others, and how much you need to do to make a difference.  Produced by Emily Bird  Got a topic you'd like us to cover?

Is now really the worst time in history to be a teenager? This week, health Journalists Cat de Lange and Helen Thomson take on a topic that worries many parents: teenage mental health. Helping them wade through the misinformation is Lucy Foulkes, a psychologist at the University of Oxford who specialises in teenage mental health and social development.  She explains why adolescence is such a vulnerable time for the brain, and why it lasts much longer than you might expect. She also shares a surprising idea about whether all our talk about mental health might have unexpected downsides. Are smartphones really villain they're made out to be, or is something bigger going on? Cat and Helen come away with practical ideas for supporting the teenagers in their lives, and a few habits they need to change themselves. Got a topic you'd like us to cover?

Why do so many of us feel calmer, clearer and more creative by the sea, a river or a lake? In this episode, Cat de Lange and Helen Thomson dive into the science of blue spaces. Picking apart the theories behind why water captures our attention and how time spent near water can change how we feel pain, our stress levels and even long-term physical health.  They’re joined by psychologist Dr Mathew White, whose large-scale studies are revealing why time near water might give our brains an extra boost over green spaces alone, and how much you really need each week to feel the effects.  Produced by Emily Bird We want to hear your thoughts, leave a comment or send in your ideas for future episodes to ⁠⁠⁠⁠⁠⁠⁠⁠[email protected]⁠ Find out more about Blue Spaces at New Scientist: https://www.newscientist.com/article/2328003-why-spending-time-near-water-gives-us-a-powerful-mental-health-boost/ https://www.newscientist.com/article/2272260-green-spaces-arent-just-for-nature-they-boost-our-mental-health-too/ Sources: https://bluehealth2020.eu/people/mathew-white/ https://www.theguardian.com/lifeandstyle/2024/oct/06/best-walk-hike-for-mental-health-uk Attention Restoration theory  https://www.tandfonline.com/doi/full/10.1080/10937404.2016.1196155 Wales study: https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196%2823%2900212-7/fulltext Large England study: https://www.sciencedirect.com/science/article/pii/S0160412024002538?via%3Dihub Moving urban to rural http://pubs.acs.org/esthag/article/48/2/1247/1481535/Longitudinal-Effects-on-Mental-Health-of-Moving-to Lake and electric shocks  https://www.nature.com/articles/s41467-025-56870-2 Lake and dentist https://journals.sagepub.com/doi/full/10.1177/0013916517710077  19 country study of blue spaces: https://natureandhealth.uw.edu/publications/the-restorative-power-of-blue-spaces-a-19-country-study/

If after a record-breaking summer of heatwaves our warming planet is weighing heavily on your mind, you are not alone. Climate anxiety is on the rise, especially among young people, but what makes it different from “ordinary” anxiety, and how should we respond?  In this episode of Change Your Mind with New Scientist Cat de Lange and Helen Thomson talk to psychotherapist and climate-aware therapy expert Caroline Hickman about why eco anxiety is a rational response to a warming world, how it is reshaping young people’s lives and decisions, and what her global research reveals about sadness, fear and a sense of betrayal. They explore practical ways to live with climate distress without being overwhelmed from reframing anxiety as care, to building resilience, to using imagination to create hopeful visions of the future.  Produced by Emily Bird We want to hear your thoughts, leave a comment or send in your ideas for future episodes to ⁠⁠⁠⁠⁠⁠⁠⁠[email protected]⁠ Find out more about Climate Anxiety at New Scientist: https://www.newscientist.com/article/2424806-what-is-eco-anxiety-and-how-can-we-overcome-it/ Sources: https://www.theguardian.com/environment/2021/sep/14/four-in-10-young-people-fear-having-children-due-to-climate-crisis https://climatecommunication.yale.edu/visualizations-data/ycom-us/ https://www.newscientist.com/article/2290232-younger-generations-are-the-most-fatalistic-about-climate-change/ https://www.cell.com/one-earth/fulltext/S2590-3322(24)00100-3 https://imagine5.com/interview/rob-hopkins-the-future-is-beautiful-but-to-get-there-we-have-to-believe-in-it/?gad_source=1&gad_campaignid=23774240607&gbraid=0AAAAA9TOeEgsQNAaHACtVCr7BZGz_jAoM&gclid=Cj0KCQjwm8bTBhDWARIsAC9Hi8lmbg6K7Ou7MYIHqmk2QBhqm52Ggr8V_ffnWSc-RLjqf_flePH7_o8aAhLBEALw_wcB

In this episode of Change Your Mind, Health Journalists Helen Thomson and Cat de Lange explore the science of cognitive reserve, the brain’s hidden resilience that can help delay the symptoms of dementia.  They talk to Professor Yaakov Stern, a leading researcher in the field, to uncover what cognitive reserve actually is, how it’s measured, and why some people stay mentally sharp despite significant brain changes. Along the way, they delve into surprising evidence on music, bilingualism, social life, exercise, and even hobbies like quilting and photography to ask how much effort we really need to put in to future‑proof our brains.

In this episode of Change Your Mind with New Scientist, Health Journalists Helen Thomson and Cat de Lange dive into the headline grabbing class of drugs behind the Ozempic boom to ask what these medications are really doing to our brains? Beyond weight loss and diabetes, early evidence hints at wide‑ranging effects on appetite, addiction, mood, and even long‑term brain health. With so many people now taking GLP‑1 agonists, are we unintentionally running the largest brain experiment in history, and what is it starting to reveal? To find out, they’re joined by Professor Paul Kenny, a leading expert on the brain’s reward and motivation systems. Together, they unpack how these drugs might quiet “food noise”, reshape our cravings, and potentially influence conditions like depression, alcohol use, and Alzheimer’s disease, while also confronting their cultural side effects, from shifting body ideals to questions about who really benefits.  Produced by Emily Bird Find out more about Ozempic and other GLP-1 Agonists at New Scientist: https://www.newscientist.com/article/2503480-the-potential-of-glp-1-drugs-to-transform-medicine-exploded-in-2025/ Sources: https://www.newscientist.com/article/2456669-why-do-ozempic-and-wegovy-seem-to-treat-everything/ https://www.newscientist.com/article/2464829-glp-1-drugs-like-ozempic-and-wegovy-lower-the-risk-of-42-conditions/ https://www.newscientist.com/article/2435246-the-surprising-mental-health-and-brain-benefits-of-weight-loss-drugs/ https://www.newscientist.com/article/2460806-well-learn-about-ozempics-potential-for-alzheimers-disease-in-2025/#:~:text=Two%20clinical%20trials%20investigating%20semaglutide,in%20treating%20this%20intractable%20condition.&text=Semaglutide%20belongs%20to%20a%20class,a%20hormone%20called%20GLP%2D1 https://www.theguardian.com/fashion/2025/oct/17/fashion-shows-fewer-plus-size-models-vogue-business
