A journey through the science of sleep as it evolves throughout our lives: from babies to teenagers, from middle age to the later years of our life, there are constantly new challenges to our sleep. Based on knowledge accumulated over almost two decades as a sleep researcher, Professor Alice Gregory shares real-life stories and interviews with other sleep experts to find the answers to questions such as: why do so many teenagers enjoy sleeping on the weekends?; why do children experiencing anxiety, behavioral problems, or attention deficit/hyperactivity disorder so often have co-occurring sleep problems?; why are scientists turning to sleep disorders such as sleep paralysis to try to understand paranormal experiences? Includes lots of tips on improving your sleep.(This book may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
