The email arrives. You read it twice. Then three times. You replay it in the shower. At 2am, you’re still writing replies in your head. This week on Wise Women’s Conversations, we finish my series on the brain after menopause with the hormone that’s been mentioned in almost every episode so far: cortisol. You’re as capable as you’ve ever been. So why can’t you shrug things off the way you used to? It’s not your imagination. Your stress response has changed. I’ve burnt out four times, so stress and adrenal burnout are topics I know from the inside. Late last year I noticed the early signs again, and because I recognised them, I knew how to turn things around. In this episode I explain cortisol as the hormone that keeps you alive, not the bad guy, and how our modern “tigers” (notifications, inboxes, the news, social media) keep it switched on all day. Using Hans Selye’s three stages of stress (alarm, resistance and rest), I show why so many successful women stay stuck in resistance, holding the weight until their body forces them to drop it. I also look at why your adrenal glands become your hormone backup system after menopause, and why stress always comes first. Then we look inside the brain. Long-term high cortisol affects your memory centre (the hippocampus) and your planning and word-finding centre (the prefrontal cortex), while it turns up your alarm centre (the amygdala). I share research from the Framingham Heart Study, Dr Lisa Mosconi’s 2024 study and a University of Southern California study, which together suggest stress shows up in women’s brains more than men’s, and that estrogen once softened that hit. For decades, estrogen and progesterone buffered you without you knowing. Now that job is yours. Perhaps you’re not falling apart. Perhaps your brain has simply handed you the job of protecting it, and that could be a gift. In this episode, you’ll discover: Why cortisol keeps you alive, and why it’s not the bad guyThe three stages of stress, and why so many women stay stuck in “resistance”How your adrenal glands become your hormone backup system after menopauseWhat long-term high cortisol does to your memory, focus and word-findingWhat the research shows about cortisol, women’s brains and memoryHow estrogen and progesterone buffered your stress response for decadesWhy poor sleep, sugar cravings, belly weight and brain fog can be stress signals, not “just menopause”Simple ways to calm cortisol: breathing, morning sunlight, mini breaks, the right exercise, regular meals, carbs, magnesium and reframing your story Questions to reflect on: Where in your life are you holding the weight longer than you need to?What are the “tigers” that keep your brain on alert each day?What early warning signs does your body give you when you’re pushing too hard?What story are you telling yourself about a situation that’s upsetting you right now? This week’s invitation is simple: The next time stress hits, stop and take three slow breaths with a longer out-breath than in-breath. Then ask: Is there anything I can change here? If not, can I let it go?
