EP7: Dr Brian Pennie – From Addiction to Academia – Can We Rewire The Brain?
What happens when you lose 15 years to heroin addiction — and then go on to earn a PhD in neuroscience to understand the brain that kept you trapped?
In this episode of Health 360: Lessons Lived and Learned, Oonagh O’Hagan sits down with Dr. Brian Pennie — neuroscientist, best-selling author of Bonus Time, and founder of Change is Possible — to talk trauma, anxiety, addiction, and the turning point that saved his life.
Brian shares the “moment of surrender” in hospital, the brutal reality of detox, and how he rebuilt his identity through learning, connection, and neuroplasticity — plus why he doesn’t do shame, regret, or resentment.

EP6: Dr Gaby Prinsloo – The Inflammation Connection What Your Gut , Skin And Body Are Trying To Tell You
What if healthier, more radiant skin has less to do with what you put on your face — and more to do with what’s happening inside your body?
In this episode of Health 360: Lessons Lived and Learned, Oonagh O’Hagan is joined by Dr Gaby Prinsloo, medical doctor, nutrition expert and Clinical Director of the Advanced Nutrition Programme, to unpack the powerful links between nutrition, gut health, inflammation, hormones and ageing.
They explore the skin barrier and why hydration matters far beyond appearance, the gut–skin–brain axis, what really disrupts your microbiome, and the biggest mistakes people make with supplements — including a no-nonsense take on collagen and “detox” culture.

EP5: Dr Louise Newson and Professor Mary Ryan – It’s Not “Just Hormones” The Truth About Women’s Health
What if some of the biggest challenges women face – from crippling period pain and PMS to anxiety, brain fog and burnout in midlife – are actually hormonal, and we’re still not joining the dots?
In this episode of Health 360: Lessons Lived and Learned, Oonagh O’Hagan is joined by Dr Mary Ryan and Dr Louise Newson to talk honestly about the full hormonal journey: first periods, PMDD, PCOS, endometriosis, fertility, perimenopause and menopause.
They unpack the confusion around “HRT and breast cancer”, explain bio-identical vs synthetic hormones, and share the red flags women (and parents) should never be told to “just put up with”.
They discuss the role hormones play in self-harm and even serious crime and how a new approach needs to happen immediately.

We know these topics can be heavy or difficult to navigate, so please take whatever space or care you need while listening.

EP4: Mark Fennell - What’s Holding You Back? Anxiety, Confidence and Self Belief
On the outside, Mark Fennell looked driven, ambitious, and capable - speaking on big stages to thousands. But behind the scenes, he was battling anxiety that wouldn’t switch off, until burnout forced him to face what was really running his life.
In this episode of Health 360: Lessons Lived and Learned, Oonagh O’Hagan talks to Mark about childhood bullying, the inner critic we all carry, and the warning signs he missed before a collapse in the gym landed him in hospital.
Mark shares the tools that helped him rebuild: identity, routine, and his mantra, “I can, I will, I must” - plus the powerful perspective shift that changed everything.

EP3: Dr Daniel Jones – Inflammation. The Hidden Driver Of Chronic Disease
What if the real driver behind low energy, brain fog, poor sleep, gut issues and even chronic disease is something you can’t see at all: silent, systemic inflammation?
In this episode of Health 360: Lessons Lived and Learned, Oonagh O’Hagan sits down with inflammation and metabolism expert Dr. Daniel Jones to break down the difference between acute and chronic inflammation, why “all roads lead to inflammation,” and how those invisible “dominoes” can spread through every system in the body.
Daniel also shares his remarkable personal story: open-heart surgery at five, a detour through music (including some unbelievable house-party moments), and the science-led journey that brought him to Ireland and to co-founding At One with Oonagh.

What if some of the most powerful tools to protect your eyesight, and maybe even your brain as you age, are already sitting on your dinner plate?
In the second episode of Health30: Lessons Lived And Learned, Una sits down with Professor John Nolan, Fulbright Scholar and Director of the Nutrition Research Centre Ireland at SETU, to explore his 20+ years of research into macular degeneration, cognition, and the surprising eye–brain connection.
John shares his own journey from struggling with undiagnosed dyslexia in school to becoming an internationally recognised scientist, and explains why specific carotenoids and omega-3s may matter for vision, mood, and quality of life, long before problems begin.
We also get to hear about his new found career in Hollywood with his fascinating new film.
