I worked as a freelance project editor on this title by author and sleep expert Heather Darwall-Smith. It was published by DK Life (part of Penguin Random House group) in June 2021. "The Science of Sleep provides in-depth answers to questions about sleep challenges and exposes myths and fads using science that is accessible to all. Armed with facts, this book equips readers to take control of their choices, understand and transform their sleep habits one night at a time."
