Episode Details

Why are you exhausted… but the moment your head hits the pillow, your brain won't shut off?

In this episode of The GoodLife in Health and Wellness, Dr. Kate Duncan breaks down the real reason behind the "wired but tired" cycle—and why sleep struggles are often not a sleep problem at all, but a stress physiology problem.

You'll learn how chronic stress disrupts the HPA axis, elevates nighttime cortisol, and prevents your body from entering deep, restorative sleep. We dive into the science behind circadian rhythm, blood sugar instability, perimenopause-related sleep changes, and how nervous system dysregulation keeps your brain on high alert long after your day is done.

This episode also walks you through practical, evidence-based strategies to help your body shift out of fight-or-flight and into rest-and-repair—so you can finally experience deeper, more restorative sleep.

If you've ever felt exhausted but unable to fall asleep… or you wake up in the middle of the night with your mind racing… this episode will help you understand why—and what to do about it.
