Why We Sleep is a comprehensive and scientifically grounded exploration of one of the most essential human biological functions—sleep. Matthew Walker, a neuroscientist and sleep expert, explains how sleep affects nearly every aspect of human health, including memory, learning, emotional regulation, immune function, and long-term disease prevention.
The book breaks down the stages of sleep and explains how each contributes to physical restoration and cognitive performance. It also highlights the serious consequences of sleep deprivation, linking it to conditions such as heart disease, obesity, depression, and reduced mental performance.
Walker uses extensive research and real-world evidence to demonstrate why modern lifestyles, technology use, and social habits are undermining healthy sleep patterns. He also offers practical advice on improving sleep quality and building better sleep routines.
Why We Sleep is widely regarded in neuroscience and health literature. It is ideal for readers interested in health, psychology, and personal development, offering a powerful and eye-opening understanding of why sleep is vital for physical and mental wellbeing.
