"Sleep consumes a third of our lives, yet we tend to only think about it when it's proving a struggle--when a baby is born, if we develop insomnia, or when ageing brings new challenges. The latest research tells us that sleep is essential for learning and memory, for mental health and well-being, and for optimal physical health. It plays a crucial role throughout our waking lives, and our relationship with sleep evolves through our different life stages, from baby to child to teenager and beyond. [This book] leads you on a fascinating journey through the science of sleep. Based on knowledge accumulated over almost two decades as a sleep researcher, Professor Alice Gregory shares real-life stories as well as insightful discussions with other sleep experts. She answers questions such as: Why are certain babies much harder to settle to sleep than others? Why do children experiencing attention deficit hyperactivity disorders often have co-occurring sleep problems? Why do so many adolescents enjoy lying in at the weekends? Are sleep problems an inevitable part of ageing? Why are scientists turning to sleep disorders such as sleep paralysis to try to understand paranormal experience? Throughout there are important tips to help you improve your sleep, allowing you to feel better during the time you're awake. This book is an essential read for anyone considering embracing the zeitgeist of prioritising sleep, and is perhaps even more important for those resisting a rest."-- from dust jacket.
