Reclaim your cycle and support your health with this detailed guide featuring 100+ recipes and practices from RN, and author of How to Grow a Baby, Amy Hammer.

There is no one-size-fits-all guide to your cycle. But registered nurse Amy Hammer arms you with a strong foundation in physiology and hormonal health, explores historical and sociocultural aspects of women’s health, and reimagines the phases of the menstrual cycle as aligning with the four seasons to provide a detailed guide for living well in your body.

    Also included are nutritive recipes (kabocha squash curry soup, seed balls, wild salmon congee), supportive movement practices to incorporate into your whole day (abdomen relief stretch, buddy walking, foam rolling), and self-care rituals and recipes (dandelion-infused breast massage oil, alternate nostril breathing) to guide you through each phase of the menstrual cycle and of life—from the young adult and menstruating years to perimenopause and menopause.

    Become in tune with your internal rhythm, reclaim the meaning of self-care, and cultivate optimal health for every season of life. This comprehensive, body-literate guide includes:

  • 40 nutrient-dense, menstrual-phase specific recipes that support hormonal, emotional, cognitive, gut, and overall health.
  • The science behind menstrual cycles and how hormonal fluctuation impacts your brain, breasts, skin, and weight.
  • How to track your cycle using fertility awareness methods, allowing you to naturally and effectively avoid or pursue pregnancy.
  • Supportive full-body movement, self-care, and nutrition tips that optimize physiological and hormonal health throughout the phases and your lifespan.

Advance Praise

“Amy Hammer separates menstrual facts from fiction in a way that is both friendly and approachable. Packed with crucial information you may have missed in health class, Cycles gives you everything you need to reclaim and embrace all the seasons of your cycle.”—Amanda Laird, registered holistic nutritionist, author of Heavy Flow: Breaking the Curse of Menstruation, and host of the Heavy Flow Podcast

“For menstruators, learning about our biology and the intricacies of our menstrual cycle is a crucial part of unlearning the stigma we’ve lived through and the misinformation we’ve maybe been exposed to. Periods are powerful, and with a deeper understanding of our bodily changes, we can make informed decisions to maximize our energies and capabilities according to our menstrual cycles. I love that this book is one step to help do that!”—Nadya Okamoto, author of Period Power: A Manifesto for the Menstrual Movement

“In Cycles, Amy J. Hammer has written a remarkably thorough, comprehensive, and accessible guide to the reproductive and sexual health of humans who menstruate. She situates menstrual cycles in context of cycles of life and seasons of nature in a way that enhances our understanding of menstruation. The text presents a finely tuned balance of the complexity and variety of individual cycles with commonalities across cycles and menstruators, with many helpful illustrations. Hammer explains medical terms for anatomy and for physiological processes clearly and concisely, without getting weighed down by jargon. Cycles can be read straight through or in sections of interest, then kept on the shelf as a reference for life.”—Elizabeth A. Kissling, PhD, professor emerita of Gender, Women’s, and Sexuality Studies, Eastern Washington University

“Amy Hammer’s Cycles is a modern update to understanding our menstrual cycles. The blend of history with modern-day science and thoughtful illustrations makes Cycles as interesting as a good novel.”—Halley Strongwater, clinical herbalist and founder of Loam Earth

“Cycles is the book you always wish you had about your cycle that breaks down the science and history behind menstruation and beyond in an accessible, easy-to-digest way, while offering no-nonsense tips to improve not only your menstrual health but overall health as well. After reading the book, it struck me just how little I knew about something I experience every month.”—Auri Jackson, producer at Buzzfeed and writer, director, and producer of The Spot

“Amy J. Hammer has written a truly comprehensive and compassionate guide to reclaiming your menstrual cycle. Cycles provides women with a ton of insight into how their bodies work and most importantly how to align their daily lives with their menstrual cycles. This is revolutionary information that will help women cultivate optimal health throughout their lives. Definitely one to have on your shelf!”—Nicole Jardim, certified women's health coach and author of Fix Your Period

Featured Reviews

Amy J. Hammer wrote the book on nurturing new life, How to Grow a Baby, so naturally she is the perfect person to write a book on the science of the menstrual cycle and how to nourish and nurture our bodies through each phase. I really enjoyed reading this book and even as a grown woman I was able to make connections between the wisdom shared in these pages and the inherent wisdom of my own body. This book is an incredible psycho-educational resource for young girls coming of age and women of every generation as Amy speaks to every life cycle stage, our hormonal changes, and the impact each stage has on us mentally, physically, biologically, and emotionally. There are also recipes and wellness practices shared throughout the text to encourage readers to think deeply and intentionally about what our bodies need, to reconnect us to our bodies, and to help us honor the changes our bodies experience. I cannot wait to get my hands-on a hard copy of this book. A wonderful addition to any home library and any professional who works directly with women.

Thank you to the author and the publisher for the e-arc copy!

This was informative, yet personal enough that it felt like you were talking to your friend about your periods. Even though I’ve been getting my period for 21 years, there is still so much I didn’t know and so much that I learned from this book! I hope that younger women pick this up to better understand their bodies!
Thank you to Netgalley and the publisher for this arc ebook in exchange for an honest review.

So often we hear stories of how woman (and others) are not taught about the female body. I found this book to be a great resource and reliable since it is written by a medical professional. This is a book I think will serve many by being on the shelf.
