'Amy's book is everything I should have learned at school. It is a reminder to empower ourselves, in a world that still sadly lacks so much knowledge around women's health, by getting to know our own bodies more intimately - with the help of technology built by women' Emma Gannon'Moody is a fascinating and friendly guide for you to understand you better.' Melissa Hemsley'Knowledge is power and this book equips you with the power to unlock potential and happiness.' Poppy Jamie, author of Happy Not PerfectThere is a secret inside you which, once you understand it fully, has the capacity to unlock untold potential. Once you learn the science of your hormones, you will be able to harness it forever.Hormones were something Amy Thomson, founder and CEO of leading women's health app and tech service Moody, never paid attention to, until one day her periods stopped and what had been an inconvenience each month became a barometer for her body's health and mental happiness. When she discovered that her hormonal burnout was driven by stress, she quit her job and focused on trying to understand how her body worked, to establish why and how she had pushed herself too far. In this guide, Amy shares the research and science behind how our hormones work for twenty-first-century survival, how understanding them can help you build better and healthier routines, and why the systems and cycles inside us are an invisible but powerful force.With insights from nutritionists, gynaecologists, endocrinologists, personal trainers and others, Moody provides a holistic and practical blueprint for understanding your hormones and optimising your life around them.
