Welcome to Chris and Xand's Daily Doses! Lees meer

January is a month when we pay considerable attention to our health and wellbeing and we all want a little reminder of some tips and tricks for how best to care for and think about our minds and bodies.

So, alongside the four main episode of What's Up Docs?, each weekday this January (other than Tuesdays), we'll be dropping a Daily Dose of expert wisdom from a previous episode. Whether it’s your knees, willpower, oral health or bringing nature into your home, Chris and Xand have got you covered.

And then in the main episodes in January, Drs Chris and Xand will be tackling the idea of change itself before going on to look at some of the big themes we often make resolutions about: alcohol, exercise and diet.

You'll find the Daily Doses in the What’s Up Docs? feed on BBC Sounds, alongside all the main episodes of the podcast.

Is joy always good for us?

Beluister deze aflevering

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken try to get to the bottom of the ideas shaping our health and wellbeing. Lees meer

In this festive episode, they turn their attention to joy. What actually is joy, and how is it different from happiness or pleasure? Why do some people seem to feel it more intensely, and does that make them more vulnerable to the emotional lows that can follow? They also ask whether we should really be striving for joy all the time, and whether its very fleeting nature is part of what makes it valuable.

To help them untangle the science, psychology and meaning of joy, they’re joined by Professor Sophie Scott CBE, Professor of Cognitive Neuroscience at University College London.

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken untangle the confusion around every aspect of our health and wellbeing. Lees meer

In this episode, they’re diving into dopamine – one of the most talked-about chemicals in modern wellness culture. But what is dopamine, really? What role does it play in pleasure, motivation, learning, and movement? And how accurate are ideas like “dopamine hits”, “dopamine detoxes”, or being “addicted to dopamine”?

Chris and Xand speak to Masud Husain, Professor of Neurology & Cognitive Neuroscience at the University of Oxford, to cut through the myths and find out what dopamine does, what it doesn’t do, and why understanding it properly might change the way we think about our behaviour and our brains.

Does what we believe about our health affect it?

Beluister deze aflevering

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken confront the confusion around every aspect of our health and wellbeing. Lees meer

In this episode, they’re asking why beliefs about our bodies are so powerful? We often think of belief as something soft – just ideas in our heads. But beliefs can shape how we experience pain, how we heal, and even how societies behave. In health, they can influence whether treatments work and how symptoms are felt.

So what actually are beliefs? Why do we them, and how do they form? And can changing what we believe about our bodies actually change how we feel?

To help answer these questions, Chris and Xand are joined by Ryan McKay, Professor of Psychology at Royal Holloway, University of London, and an expert on the psychology of belief.

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken tackle the confusion around every aspect of our health and wellbeing. Lees meer

In this episode, they’re asking, what’s the deal with naps? Some people nod off in minutes, while others can’t manage it at all. So why is napping so different from person to person? Is it actually good for us? Is there a “right” way to nap - and should we all be making time for it? Also, they uncover what’s really happening inside the brain when we drift off.

To help answer these questions, they’re joined once again by Russell Foster, Professor of Circadian Neuroscience at the University of Oxford.

Can psychedelics improve your mental health?

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken untangle the confusion around every aspect of our health and wellbeing. Lees meer

This week, Chris and Xand meet Dr James Rucker, a consultant psychiatrist at King's College London who is leading the European arm of a global trial of a psychedelic called psilocybin in a study designed to treat people with severe depression for whom other pharmacological treatments have failed.

The use of psychedelics in both traditional medicinal and spiritual ceremonies dates back thousands of years and examples include peyote and ayahuasca from Central and South America, Iboga root from Central Africa and LSD, which is synthesised from a fungus found throughout Europe. As the number of clinical trials involving psychedelics increases, scientists are cautiously optimistic that they may be able to help with a range of conditions from eating disorders and anxiety to depression and addiction.
