Squaring the Circle is a cutting-edge and comprehensive collection of the latest research and debate on normal childbirth. Based on a salutogenic approach – focusing on factors that support human health and well-being, rather than on factors that cause disease – it helps our understanding of what works and why it works, as well as helping health practitioners turn this knowledge into best practice. Written by world-renowned experts in their field, and edited by Soo Downe and Sheena Byrom, the editors of the acclaimed The Roar Behind the Silence, Squaring the Circle includes an examination of a range of associated evidence in areas as diverse as architecture for optimal birth environments, the impact of birth events on neonatal DNA methylation and the microbiome, the current knowledge base around oxytocin production in labour, and the role of emotion in the workplace. Case studies of successful change from around the world – from service users, activists and maternity care staff – provide inspiration for innovation while hints and tips help to make such change happen.
