The Cortisol Cure

For fans of Good Energy  and Age Like a Girl comes a groundbreaking book from the “Stress Reset Expert,” Dr. Erin Kinney, sharing that contrary to popular belief, cortisol isn’t the enemy—it’s an essential hormone your body depends on to function, heal, and thrive – and the key to reclaiming your health isn’t lowering cortisol, but restoring your natural supply. 

Our relationship to cortisol, the stress hormone, is often misconstrued. We believe cortisol is bad—something we want to lower and keep at bay. But here’s the truth: the migraines, bloating, mood swings, weight gain, and joint pain may not stem from too much cortisol at all. More often, they arise when your body’s cortisol levels are depleted. When you learn how your system really interacts with this vital hormone, you create the conditions for your body to repair, rebalance, and reset. 

In The Cortisol Cure, Dr. Erin Kinney introduces her powerful and accessible framework: the “Cortisol Bank Account.” Think of cortisol as the “currency” your body uses to generate energy, handle stress, heal, and perform at its best. When you rest, you earn cortisol. When stress demands your attention – physical, emotional or environmental – you spend it. . And just like with any budget, when you consistently spend more than you earn, you slip into hormonal debt. This debt sends your body into survival mode and can manifest as a wide range of symptoms that feel mysterious or disconnected. 

This book maps the journey Dr. Kinney has used to help over 7,000 patients and clients heal their body, health, and life. You will: 

• Understand what you want for your body—you’ll learn how to balance your relationship with cortisol in each area of your life. 

• Read real patient stories that illustrate the science in clear, relatable, and empowering ways. 

• Learn habits that you can put into practice—and that will stick for the long term. 

The Cortisol Cure is a wake-up call and action plan for anyone who doesn’t feel well and isn’t sure why, but needs to feel better. If you’re human and you want to be well—this book is for you. 

• The Cortisol Cure by Dr. Erin Kinney, is not simply an accomplished treatise on 'the' critical stress hormone made by the body; it is also a beautifully written and easy-to-understand tour through common symptoms and syndromes that physicians often find mysterious, and perhaps more importantly, what you can do about them.  Having the honor of participating in her medical training, this is unsurprising; Erin is one of our bright stars in functional and naturopathic medicine, and I eagerly look forward to her future writings and discoveries.

• “Dr. Kinney takes the notoriously complex topic of cortisol and chronic stress and breaks it down into clear, accessible, and actionable insights. She offers simple, practical frameworks to help address symptoms that so many of us are experiencing including constant fatigue, stubborn weight, poor sleep, pain, and digestive issues, so you can finally start supporting your body’s natural ability to heal.”

• “As a therapist I work with so many burned-out, exhausted women who are doing everything 'right' and still not getting better. This is a must read. Dr. Kinney articulates what so many of us have sensed but couldn't fully explain, that what looks like depression, anxiety, or emotional dysregulation is often a body running on empty. The Cortisol Cure gave me a framework I now reference constantly in my own clinical thinking and with other mental health professionals. It will deepen your understanding and make you a better advocate for whole-person healing.”

• “Dr. Erin Kinney offers an eye-opening look at the role cortisol plays in our mood, metabolism, sleep, digestion, and even our sense of connection. In The Cortisol Cure, she reveals how the relentless demands of modern life disrupt the nervous system and shows readers how to restore balance in their bodies. As a relationship coach for high performers, I often work with couples who deeply love each other yet struggle with fading desire. Chapter 7 in particular illuminates how restoring balance to the nervous system can reignite desire at the biological level. The Cortisol Cure distills complex science into practical, easy-to-understand tools readers can apply right away. I highly recommend this book.”

• "With equal parts science, story, and soul, Dr. Erin Kinney deconstructs stress at every level of our being. She reveals how stress lives in our bodies—hormonally, emotionally, energetically—and shows us how to alchemize it, no matter how long it's been building. Her guidance is practical, doable, and deeply empowering, reminding us that resilience isn't just about bouncing back; it's about remembering the power we already have to heal, even when life feels hard. The Cortisol Cure is medicine for these times—the kind that reminds you you're not alone in them.”

• As a somatically oriented trauma therapist, I've wished for a book like this for more than a decade! Over the years since my health crash, I've had to cobble together the solutions to address my symptoms. Now, thanks to Dr. Erin Kinney, there's a book which brings together all the latest information on addressing cortisol imbalance into a clear, understandable framework that will be invaluable to clinicians and clients. I highly recommend this book!

• In The Cortisol Cure, Dr. Kinney makes stress physiology human, honoring the full story behind symptoms rather than reducing healing to numbers alone. What stands out most to me is her emphasis on attunement—understanding the whole person and restoring safety and support as foundational to recovery. In my work, I’ve seen how transformative it is when someone feels truly seen, and this book offers that same experience for anyone who has felt alone in their symptoms and is ready for a more supportive path forward.
   
  Deanna Smith, Life Coach
• “The Cortisol Cure is the book everyone needs, and the book I wish I had ten years ago. Dr. Kinney makes the science of the stress response both digestible and understandable, while offering actionable steps you can implement immediately. She beautifully weaves together the vulnerable parts of her personal story, her years of clinical expertise, and the physiology of the autonomic nervous system, creating a narrative that reads more like a story you can’t put down. I highly recommend The Cortisol Cure for everyone. It’s a resource I’ll be using in my clinical practice and will be returning to as a litmus test for my own nervous system for years to come.”
