7 Habits a neuroscientist swears by to keep your mind sharp at any age | Dr Tommy Wood

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.
