Why We Sleep: The New Science of Sleep and Dreams

Why We Sleep: The New Science of Sleep and Dreams synthesizes decades of sleep research into an accessible exploration of how sleep shapes cognition, emotional regulation, and physical health. Kimberley Wilson and Matthew Walker examine the mechanisms behind REM and non-REM sleep, explain why dreams matter, and reveal how sleep deprivation affects memory, immunity, and metabolism. The book moves beyond popular myths - such as the belief that we can train ourselves to need less sleep - and presents evidence-based guidance for improving sleep quality.

Wilson and Walker address practical concerns: how light exposure influences circadian rhythms, why alcohol disrupts sleep architecture, the role of temperature and exercise timing, and how age affects sleep needs. The science is grounded in laboratory studies and clinical observation, making it relevant whether you struggle with insomnia, shift work, or simply want to understand your dreams better. Readers gain actionable strategies without pseudoscience or oversimplification.

This 2020 edition brings recent neuroscience findings into conversation with everyday sleep problems, offering both explanation and intervention. Available nationwide with Cash on Delivery at OnlineBooksOutlet.
