Welcome back to The Human Mix.
In this episode, Nick and Lydia are joined by science journalist and author Caroline Williams to explore the surprising ways our bodies shape our minds.
Drawing on her books Move and In a Sense, Caroline shares how movement, strength, and our internal signals are fundamental to mental health, decision-making, and our sense of self.
The conversation ranges from the evolutionary roots of movement to modern neuroscience showing how our brains constantly predict and respond to what’s happening in the body.
Caroline explains how practices like yoga, breathing, and even flotation tanks can heighten awareness of internal signals, supporting people with anxiety, addiction, and body image struggles. She also offers practical ways to tune into your body’s cues, whether that’s noticing when you’re hangry, stretching after tension builds, or simply walking forward to shift your mindset.
Together, they explore the balance between listening to your gut and not being ruled by it, how interoception is becoming the “new microbiome” in science, and why strength training can transform self-esteem long before muscles visibly change.
With humour, honesty, and science made accessible, Caroline makes the case that movement and body awareness are far too important to be left to the fitness industry—they’re essential tools for resilience, wellbeing, and everyday life.
