Dreaming of Answers

We spend nearly a third of our lives asleep, yet most of us understand surprisingly little about how sleep actually works-or why it fails. In an era of wearable trackers, melatonin supplements, and conflicting advice, confusion about sleep has never been greater. In Dreaming of Answers, Walter James, MD, draws on decades of clinical experience and modern neuroscience to explain the architecture of sleep, the purpose of REM and deep stages, and the biological systems governing circadian rhythm, memory consolidation, and brain restoration. He examines common disorders-including insomnia, sleep apnea, parasomnias, and fragmented sleep-and distinguishes what is supported by evidence from what is not. Clear and rigorously grounded, this book moves beyond folklore and quick fixes, offering readers a deeper understanding of why sleep matters-and what practical steps can meaningfully improve the quality and stability of restorative sleep. "A useful and authoritative guide that both physicians and patients will benefit from." -James Braude, MD, Primary Care Internist
