How much caffeine is too much? In this episode of Extra Catch with Shaun Stafford, we're taking a deep dive into caffeine. Is it actually bad for you? How can I optimise it for performance? And when does its overuse become too dependent?

How soon should we start taking our dementia risk seriously?

In today’s episode of ZOE Science & Nutrition, Jonathan is joined by Prof. Claire Steves to explore the multifaceted world of dementia. They delve into the significance of dental health, genetics, diet, and physical activity — plus, they unpack the latest research — to give you practical strategies for preventing dementia.

Claire is a consultant physician in geriatric medicine at Guy's and St Thomas' NHS Foundation Trust. She’s also a senior clinical lecturer at King's College London and deputy clinical director of the institution’s Department of Twin Research and Genetic Epidemiology where she leads research on the characterization of physical and mental aging traits and frailty.

In this series of special editions of BBC Radio 4 podcast Just One Thing, Michael Mosley quizzes the world’s leading health experts on the best ways to live well. In this Sleep Special, we hear from Professor Russell Foster - Director of the Sleep and Circadian Neuroscience Institute at the University of Oxford and one of the world’s leading researchers on what makes our body clocks tick. We hear the top tips that Professor Foster lives by to improve the way we sleep and live. How many hours do we really need to ensure a refreshing slumber? What is our chronotype and can we adapt it? And what are the dos and don’ts of sleep hygiene that we should all follow? And as this is a Just One Thing special, we'll end each interview by asking Professor Foster for the one single most effective health hack to get a good night’s rest.

I’m willing to bet oxygen isn’t front-of-mind for most of us each day. We can get what we need at any given moment: enough to conveniently power our lungs and bodies without any conscious work on our part. So you might be surprised to learn that oxygen is somewhat of an undercover superhero, and Hyperbaric Oxygen Therapy (HBOT) unleashes its powers for dramatic healing. 

HBOT uses air pressure 2 to 3 times higher than the atmospheric pressure around us, helping our lungs gather much more oxygen than would be possible by breathing pure oxygen at standard air pressure. Amplifying oxygen in this way creates an environment that helps fight bacteria and triggers growth factors and stem cells for deep healing. 

On today’s episode of The Doctor’s Farmacy, I’m excited to talk to Dr. Scott Sherr all about Hyperbaric Oxygen Therapy and how we can use it to maximize healing and reverse aging.

Dr. Scott Sherr is a Board Certified Internal Medicine Physician Certified in Hyperbaric Oxygen Therapy and Health Optimization Medicine (HOMe). He is the founder of Integrative HBOT, a worldwide telemedicine practice where he consults and educates patients and clinics using his novel approach to hyperbaric therapy that includes cutting-edge and dynamic HBOT protocols, comprehensive laboratory testing (using the HOMe framework), targeted supplementation, personal practices, synergistic technologies (new and ancient), and more.

The physiological and neurological difference between being awake and asleep.

What a neurotransmitter is and how it changes composition when asleep.

What the functions of our brain’s two hemispheres are.

How sleep cleans the brain.

The connection between sleep and neuroplasticity.

The link between sleep and brain health.

Take a nice deep breath in… through your nose. It’s a simple way to get healthier gums, a better memory, and improved lung function. How? Well, it may partly be due to a special molecule called nitric oxide. Michael Mosley speaks to Professor Jon Lundberg from the Karolinska Institute in Sweden who made the fascinating discovery that nitric oxide is produced in your nose and travels to your lungs where it has some surprising benefits, including boosting oxygen uptake and possibly helping you fight off infections. Our volunteer Joe tries out a few tips to make nasal breathing a habit.

In the UK, one in 14 people over 65 will develop dementia, with that figure rising to one in six once we’re over 80. But there are plenty of simple, enjoyable things that we can all start doing right now to improve our brain health and stave off age-related dementia.

Feel Better Live More Bitesize is my weekly podcast for your mind, body, and heart.  Each week I’ll be featuring inspirational stories and practical tips from some of my former guests.


Today’s clip is from episode 316 of the podcast with Dr Tommy Wood. In this clip, Tommy explains why cognitive decline in later life is not inevitable and the steps we can take now to keep our brain healthy at any age.

There’s been a surge in our consumption of ultra-processed foods, especially in the United Kingdom and the United States, where these foods contribute about two-thirds of people’s caloric intake.

Also a cause for concern is emerging evidence of ultra-processed foods’ detrimental effect on our brain health and overall well-being.

When most of our calories come from ultra-processed foods, the risk of chronic physical and mental health conditions escalates. Scientists are now uncovering the intricate mechanisms behind this relationship, particularly concerning the effects of these foods on our brains.

In today’s episode, we welcome back Prof. Felice Jacka, OAM. Felice is an Alfred Deakin professor of nutritional psychiatry and the director of the Food & Mood Centre at Deakin University, in Australia. She’s also the founder of the International Society for Nutritional Psychiatry Research and the world’s leading researcher on food’s impact on our brain and mental health.

Now, she’s back on the show to delve deeper into the effects of ultra-processed foods on mental health and the brain, specifically the hippocampus, an area responsible for learning and memory.

Is there a nutrition topic you’d like

It’s pretty well known that if you wait to make a big decision until after you get some sleep, you’re likelier to make a good one. But why should that be? Why, we’ll explain if only you’d listen.
