Cold-Water Swimming and Sauna - Can hot and cold therapies boost mental health? May 28, 2026

Show notes

If you’ve ever wondered whether the cold‑water swimming craze is a genuine brain booster or just a very chilly fad, this episode is for you. New Scientist journalists Cat de Lange and Helen Thomson plunge into the science behind cold dips, ice baths and saunas, asking whether they really can lift mood, protect the brain and build resilience, or if a warm pool and a chat with friends would do just as much.

Along the way, Cat and Helen explore why so many people feel transformed by getting into very cold water, and what might really be driving those post‑swim highs. Is it something special happening inside the brain and body or the simple magic of nature, community and ritual?

They’re joined by Professor Mike Tipton, a world‑leading expert in how our bodies respond to extreme environments. Together, they ask: in an age of central heating and air conditioning, have we made ourselves too comfortable for our brains and bodies’ own good?

Supplements - The Surprising Pill that Actually Helps your Brain May 21, 2026

Show notes

If the wellness industry has you wondering whether your daily supplements are helping your brain, or just draining your bank account, this episode is for you. New Scientist journalists Cat de Lange and Helen Thomson reveal the science behind multivitamins, omega-3s, vitamin D, creatine and more, separating the snake oil from the evidence that actually stands up.

Along the way, they unpack why even the most scientifically minded people can fall for wellness trends, how social media has transformed the supplement boom, and what researchers are really discovering about brain health as we age.

They’re joined by Harvard professor and physician JoAnn Manson, who has led some of the largest and most rigorous studies ever conducted on supplements and cognition. From surprising findings on multivitamins to the truth about chocolate, fish oils and “brain boosting” pills, this episode explores what’s worth paying attention to, and what might be better left on the shelf.

Rethinking Anxiety - The Simple Shift that Changed my Life May 14, 2026

Show notes

In the very first episode of Change Your Mind, New Scientist journalists Cat de Lange and Helen Thomson tackle one of the most common, and misunderstood, mental health challenges: anxiety. Why do some people bounce back from stress while others feel trapped in a constant state of alarm? And why is anxiety rising so sharply, especially among younger generations?

Helen opens up about her own experiences with overwhelming anxiety, from panic on a flight home to the quieter daily dread that so many people hide beneath the surface. Together, Cat and Helen cut through the social media quick fixes to explore what neuroscience really tells us about anxious minds.

They’re joined by psychotherapist, former NHS clinical lead and bestselling author Owen O’Kane, whose radically compassionate approach reframes anxiety not as a flaw to eliminate, but as a protective system that’s working overtime. Drawing on neuroscience, therapy and personal experience, Owen explains why calming the body must come before calming the mind and shares practical strategies that can genuinely help.
