Why We Sleep

More about the book

This groundbreaking exploration of sleep by Professor Matthew Walker, Director of UC Berkeley's Sleep and Neuroimaging Lab, reveals how to harness sleep's transformative power for better living. Sleep is crucial yet poorly understood, with science recently uncovering its vital role in our wellness and longevity. For years, the purpose of sleep remained a mystery, but recent discoveries have illuminated its significance. Walker provides a fresh perspective on how sleep and dreaming enrich our learning, memory, and decision-making abilities. Sleep also recalibrates emotions, boosts the immune system, fine-tunes metabolism, and regulates appetite. Dreaming helps process painful memories and fosters creativity by blending past and present knowledge. Walker addresses key questions about sleep, including the effects of caffeine and alcohol, the nature of REM sleep, and how sleep patterns evolve over a lifetime. He also discusses the impact of sleep aids and their potential long-term consequences. By synthesizing decades of research, Walker shows how to leverage sleep to enhance learning, mood, and energy; regulate hormones; prevent serious health issues; slow aging; improve children's education; and boost business productivity. This clear and accessible work is essential for understanding the profound importance of sleep.
