CORTISOL: The science behind the stress

In this What's My Age Again bonus episode, Dr. Nichola Conlon turns the lab lens on cortisol.

Beyond the usual wellness hype, she breaks down what's actually happening behind the scenes when stress takes hold, how it impacts your long-term health, and why not every solution you read about on the internet is worth your time.

Dr Nic separates fact from fiction on this hot topic plus she delves into her case files to hear how much sleep Gavin and Stacey’s Joanna Page really gets.

Katherine Ryan takes a forensic look into her celebrity guests' lifestyle, relationships, medical history, mental health and anti-ageing rituals (or lack of) before revealing how all this has affected their biological age, and how it compares to the number on their birth certificate.

Diving into the science behind the (sometimes) scandal, Dr Nichola Conlon, who has a PhD in biochemistry, is on hand to decode the results, separating the science from the snake oil and explaining what they can actually do about it.
