As part of the BBC’s mental well-being season, All in the Mind takes a deep dive into the evidence on the relationship between exercise and mental health. Not just whether getting moving can make a difference, but why.

Claudia Hammond laces up her running shoes and goes for a jog on the seafront in Eastbourne with a group of people who are running for their mental health. Claudia meets the founder of 'Run Talk Run', Jess Robson, and talks to other members of the group about why they find exercise to be helpful.

Back in the studio, Claudia speaks to Jonathan Roiser, Professor of Neuroscience and Mental Health at University College London. He’s about to embark on a major piece of research that should help us understand a lot more about what exercise does for people with depression. As well as explaining what they’re hoping to discover, he tells her about the latest research into exercise and mental health. Why does it work for some people and not others, and what’s the best exercise for your brain?

Then there’s the commonly held belief that exercise is good for your mood because it ‘gets the endorphins going’, but we know that endorphins are not able to cross the blood-brain barrier. Claudia talks to Dr Hilary Marusak from Wayne State University School of Medicine in Detroit about one of the possible alternatives – the endocannabinoid system.

Throughout the programme Claudia is joined by Dr Peter Olusoga, Senior Lecturer in Psychology at Sheffield Hallam University. Together they discuss the many barriers people face to improving their physical activity, including the fact that poor mental health itself can stop you wanting to exercise in the first place.

And if getting more exercise really does sound like the worst idea you can think of, it turns out that watching sport on TV might also be good for you.

First today, a story of alleged academic fraud. The allegations against Professor Francesca Gino might seem unremarkable at first sight. After all, we’ve covered allegations of fraud in psychology on All in the Mind before and the field has been doing all sorts to try to fix the problems. But what is unusual about this eminent Harvard researcher is that her research topic is dishonesty. Yes, a dishonesty researcher accused of the doing the very thing she studies. Cathleen O’Grady reports on a tale of data sleuths and multi-million dollar law suits.

Of course there’s no reason why a dishonesty researcher should be any more honest than anyone else. But somehow we feel as though you should have extra high standards if this is the topic you study, otherwise you could be accused of hypocrisy. Which got us wondering what it is about hypocrisy that interests, and sometimes infuriates, us so much? Professor Catherine Loveday, from the University of Westminster, is in the studio with Claudia to take a look at the evidence.

And we hear from Professor Rory O’Connor, at the University of Glasgow, about a generation of men whose suicide risk appears to have followed them through life. We talk about what that generation can tell us, as well as about the latest suicide statistics for England, and about what you can do to help someone in your life who you think might be having suicidal thoughts. And if you are suffering distress or despair, details of help and support are available at bbc.co.uk/actionline.

And finally, were you lucky ones enough to see the Northern Lights this weekend? Claudia and Catherine Loveday unpack the psychology of awe.

In this episode of All in the Mind, we’re at the 2024 Northern Ireland Science Festival where we’re discussing the psychology of hope.

With a live audience in Belfast’s Metropolitan Arts Centre, Claudia Hammond is joined by a panel of experts well-versed in the topic of hope: Dr Karen Kirby, senior lecturer in psychology at the University of Ulster; Dr Kevin Mitchell, associate professor of genetics and neuroscience at Trinity College Dublin; and author Sinéad Moriarty.

We take a look at the role of hope in medical scenarios, if we can learn to be hopeful, and how we can hold onto hope in the modern world. And we take questions from our audience – including whether or not we should all just lower our expectations.

Are you looking forward to the lighter evenings of summer? Perhaps you're already feeling different as the seasons change and the green shoots of spring arrive? This week on All in the Mind we're taking a look at how the seasons affect our moods, thoughts and behaviours. Claudia Hammond speaks to Michael Varnum from Arizona State University about what the research says. Cognitive neuroscientist Sophie Scott, joins Claudia in the studio to ask what it means for the science of psychology if the seasons have such a profound effect.

And we hear from a project in Northern Ireland that teaches people to have hope. Marie Dunne was inspired to set up the project, called Resilio, after witnessing the success of a programme designed to teach hope in schools. Based on that programme Resilio developed their own hope courses for adults. We hear from people who have benefitted from those courses, and from people who run them, about how to find hope.

Finally, Sophie Scott discusses a new study which found that male psychology scholars were less likely to think of female scholars when asked to name eminent researchers in that field. Could it explain the gender cap in citation rates?

If you've been cured of a phobia, say of spiders, and finally made your peace with the hairy-legged beasties in real life - why might you then start having vivid nightmares about them?

Following an email plea for an explanation of this mystery Claudia Hammond enlists Dr Lampros Perogamvros, a psychiatrist from the University of Geneva who’s done extensive research around dreams and nightmares, to help answer listener Lesley's query.

Meanwhile a new study by researchers at the USA's Columbia University is looking into the benefits of treating post-cardiac arrest PTSD with mindfulness. Claudia speaks to research scientist Dr Maja Bergman about how she was motivated to start the project by her own experience of a sudden cardiac arrest, in her thirties. We also hear from survivors via the support group Sudden Cardiac Arrest UK, about their experiences and recoveries.

Joining Claudia in the studio to discuss these stories and more is Dr Peter Olusoga, a Senior Lecturer in Psychology at Sheffield Hallam University - who also has thoughts to share on new research into athletes shouting at umpires, and what affects our levels of impatience.

These days we see a lot of negative stories related to screen time – how we’re addicted to our phones and social media is damaging our mental health. But is our panic about screens justified? Pete Etchells, professor of psychology and science communication at Bath Spa University, talks Claudia Hammond through the latest evidence in this field – and it turns out it’s all a lot more complicated than we think.

Many of us will often get catchy tunes stuck in our head, or have an inner monologue narrating our experiences. But this isn’t the case for everyone – some people have what they describe as a silent inner world. This inability to hear sounds in your head has been named anauralia, which PhD student Sang Hyun Kim experiences, and he describes his inner life to Claudia. We also hear from Professor of Psychology Tony Lambert, who has been running studies into anauralia at the University of Auckland.

And Claudia is joined in the studio by Catherine Loveday, Professor of Cognitive Neuroscience at the University of Westminster, who has also recently published a study on anauralia – and puts Claudia’s auditory imagery skills to the test. And Catherine also talks us through a new study on how live music can amplify emotional responses in the brain.

When it comes to mental health, what's going on with young people - particularly, teenage girls?

There's been a lot of coverage in the media recently regarding mental health difficulties facing boys, not least around the struggle to get to grips with 'modern masculinity'; undoubtedly, it's a tough time to be a young man.

But looking at figures for mental health problems in children and teens, there's clearly something going on with girls too. For some years now, research has shown that more girls are experiencing problems than boys, with a troubling spike in difficulties showing up in the late teens. In some years, twice as many girls as boys have what the research calls “probable mental health disorders” - with rates of eating disorders charting four times higher and rates of self-harm up to seven times higher in girls than in boys.

All sorts of factors can affect those figures, from whether people are prepared to discuss how they feel, to how those feelings are labelled.

On today's programme, Claudia explores the issue with help from a variety of guests, visiting King's College London's (KCL) Institute of Psychiatry, Psychology and Neuroscience to speak to Gemma Knowles, a lecturer in epidemiology and youth mental health; Craig Morgan, professor of social epidemiology and co-director of ESRC Centre for Society and Mental Health; and Valeria Mondelli, a clinical professor of psychoneuroimmunology - about their work with young people in the UK and beyond, trying to uncover the deeper causes and to find new solutions.

She also hears from some of the young people involved in a major study into mental health, conducted by the team at KCL and spanning nearly a decade.

Claudia is joined by Dr Linda Blair, a clinical psychologist, who brings her own professional experience to bear discussing the trends and challenges of youth mental health.

Does what we eat have an impact on our mood and memory? And should we be thinking about brain health when we make diet choices? Claudia Hammond speaks to Dr Ellen Smith from Northumbria University about the latest food supplement taking TikTok by storm; Lion's Mane mushrooms. We are used to foods being promoted for their physical health benefits, but this one is being claimed to reduce brain fog, improve memory and fend off Alzheimer's disease. Claudia asks what the science says and discusses with studio guest Dr Sarah King from the University of Sussex whether and what we should be eating to boost our cognition.

And Claudia's off to see a new play; This Might Not Be It is currently on at the Bush Theatre, London. It tells the story of two administrators in an NHS mental health clinic and addresses the challenge of staying optimistic in a system that is struggling. Claudia is accompanied by mental health campaigner James Downs, and speaks to the writer of the play, Sophia Chetin-Leuner. Studio guest Sarah King discusses why drama is so powerful in helping us connect with people's stories.

How stressed out do you get by TV quiz shows? And would that change if you were a contestant yourself? Cognitive researchers at the University of Arizona have studied back-episodes of Mastermind to find out how people react in high-stress situations - particularly how much they blink. Their findings offer insight into how blinking changes in stressful and mentally challenging situations – but also what it can tell us about cognitive processes. Claudia Hammond hears from BBC presenter and Celebrity Mastermind "Champion of Champions" 2019, Samira Ahmed, and speaks to Bob Wilson, associate professor in cognitive science and psychology at the University of Arizona, about the research.

Have you ever walked into a room and completely forgotten what you came in for? Studies show that changing your physical location can "bookend" thoughts and shape how our memories compartmentalise information. Now a new study has been looking at whether shifts in our moods can do the same. Researchers at the University of California, Los Angeles, used music to elicit specific emotions in subjects, so they could assess how changes in emotional states might affect how memories are formed. Claudia hears from assistant professor of psychology, David Clewett, one of the paper’s authors.

And this week's studio guest Catherine Loveday, professor of cognitive neuroscience at the University of Westminster, explains why anger can on occasion be a rather useful emotion.

Increasing numbers of people are avoiding the news, and a recent update to Ipsos’s Global Trends 2023 report has found that the current state of the world is causing people to focus on their own lives, rather than broader, global problems. Mike Clemence, associate director of trends & futures at Ipsos, talks Claudia Hammond through the findings and the "polycrisis" we find ourselves in. Coverage of these crises can have a psychological impact, Roxane Cohen Silver, distinguished professor of psychological science, medicine, and public health at the University of California Irvine, tells Claudia how media exposure to traumatic events can cause acute symptoms of stress, and what we can do to protect ourselves.

Whistleblowers do the important job of calling out wrongdoing in an organisation. So why are so many treated badly, even though they’ve done the right thing? And how can people be encouraged to raise concerns at work? Claudia speaks to Amy Edmondson, professor of leadership and management at the Harvard Business School, about "psychological safety" – the belief that you won’t be punished for speaking up.

And Claudia is joined in the studio by Daryl O’Connor, professor of psychology at the University of Leeds, to take us through some of the latest findings in neuroscience and psychology. We discuss whether compassion is a limited resource and if the emotional words we use can affect our heart health.
