Why We Sleep has a singular goal: to reunite humanity with sleep. The book provides a complete description of, and prescription for, sleep. It answers critical questions about sleep: how do caffeine and alcohol affect sleep? What really happens during dreaming? Why do our sleep patterns change across a lifetime? Why are sleep pills linked to a higher risk of death and cancer? Charting cutting-edge scientific breakthroughs, and synthesizing decades of research and clinical practice, Why We Sleep explains how we can harness sleep to improve learning, mood, and energy levels; regulate hormones; prevent cancer, Alzheimer's, obesity, and diabetes; slow the effects of aging; increase longevity; enhance the education and lifespan of our children; and boost the efficiency, success, and productivity of our businesses. The book concludes with a provocative new vision for sleep in the modern world - one that aims to solve the greatest public-health challenge we now face: the global sleep-loss epidemic.
