Why We Sleep by Matthew Walker | Sleep Science Book

In Why We Sleep, neuroscientist and sleep researcher Matthew Walker takes readers inside the science of sleep to explore why we need it and what occurs within the brain and body while we rest.

Walker examines topics including REM and non-REM sleep, dreaming, circadian rhythms, memory formation, learning, emotions and the effects of sleep deprivation. He also considers how factors such as caffeine, alcohol, artificial light, work schedules and modern routines can influence sleep.

Rather than treating sleep as simply downtime between waking hours, the book presents it as an active biological process closely connected with how we think, feel, learn and perform.

Combining scientific research with practical explanations, Why We Sleep encourages readers to reconsider the role that quality sleep plays in building a healthier, more capable life.
