The book addresses the topic of sleep from several angles, beginning with the mechanisms of sleep: its stages and the physiological and psychological factors that affect it; then moving on to various sleep disorders (insomnia, fragmented sleep, nightmares, night terrors, sleep paralysis), particularly the impact of psychological trauma and post-traumatic stress disorder on sleep quality; in addition to various effective techniques and practices for dealing with sleep disorders, with a detailed explanation of how to implement them and how to combine them for maximum benefit. While the book addresses sleep scientifically, using some medical terminology and citing numerous scientific studies, specialized research, and statistics, its style is simple and detailed, making it suitable for the average, non-specialist reader. Through its exploration of sleep, the author aims to draw our attention to its vital role in improving our overall quality of life. Hence the book's title: "We are not truly awake until we sleep."
