One of the biggest myths about brain health is that decline is inevitable as we get older. That at some point our memory fades, our thinking slows down, and there’s not much we can do about it.

My guest today argues the opposite.

Dr Tommy Wood is a neuroscientist, Professor at the University of Washington, and performance consultant to world-class athletes.

He’s published more than 100 scientific papers and has lectured all over the world on brain health, metabolism, physical activity and human performance.

He’s also the author of the brilliant new book The Stimulated Mind: Future-Proof Your Brain from Dementia and Stay Sharp at Any Age (Harmony, March 2026).

It’s a really practical conversation about small, everyday habits that can keep your mind 🧠 sharper for longer, without needing extreme diets or stacks of nootropics.

He walks us through 3 powerful levers to sharpen your mind:

1. How to stimulate it with specific exercises and mental challenges
2. How to supply it with key nutrients
3. And how to support it by changing your perspective on stress and sleep

I’ve already changed a few simple things in my daily routine, and I’ve been sharing it with friends and family because this is something that really matters to most of us: keeping our minds sharp through life. I hope you find this conversation as useful and motivating as I did.

If you want specific recipes and meal ideas, we have a whole brain‑healthy collection on the Doctor’s Kitchen app and website to help you put these principles into practice straight away.

We breathe over 20,000 times a day. Those breaths do far more than just keep us alive. They shape your sleep, your focus, your energy, even your blood pressure and long-term risk of disease.

That’s over 20,000 opportunities to support your health, every single day.

The challenge is that modern life makes it harder to breathe well. We sit hunched over laptops, we’re constantly switched on, we chew softer foods, and many of us mouth-breathe, especially at night.

My guest today is on a mission to improve our health through our breath.

James Nestor is an award-winning science journalist and author of the bestseller “Breath”. He’s travelled the world to understand how our breathing has changed, and most importantly, what simple, practical steps we can take to improve it.

This episode genuinely shifted things for my team and me. I hope it inspires you to make a few small changes too. And if you know a committed mouth breather, send it their way.

We cover:

• The risks of mouth breathing and James’ 10-day experiment
• Why nasal breathing makes such a difference
• Tips for a blocked nose or deviated septum
• How to train your diaphragm for easier breathing
• Why softer modern diets can affect your airways
• Whether “mewing” is worth trying
• Easy breathing habits you can start today

I talk a lot about what we eat for our health. But what about the air we breathe at home?

If you or your kids have asthma, constant sniffles, a lingering cough, sinus issues, or you’ve noticed damp patches and that musty smell, this episode could change how you think about your home.

As a new dad, I'm personally really interested in how our home environment shapes early immune development. This conversation made me think differently about ventilation, condensation and what really matters.

My guest is Dr Peter Cook, a Wellcome Trust Sir Henry Dale Fellow at the MRC Centre for Medical Mycology at the University of Exeter. His research looks at how airborne fungal spores interact with the immune system and drive allergic and asthmatic disease, an area that has been surprisingly neglected.

In this episode, we go into:

• What mould actually is and when it becomes a problem
• What is a safe level of mould?
• How mould exposure can trigger asthma and allergic disease
• Who’s most at risk
• Whether mould testing kits are worth your money
• If dehumidifiers and air purifiers actually work
• Practical steps you can take this week to reduce your exposure and protect your health
