Why We Sleep

Sleep turns out to be doing more work than almost any other part of a daily routine, and Matthew Walker sets out the evidence. A neuroscientist and sleep researcher, Walker explains what happens across the night's cycles, why dreaming appears to matter for memory and emotional processing, and how shift work, screens, alcohol and early school hours interfere with it. The material is drawn from published research and presented for general readers, with practical implications rather than a rigid programme. Why readers return to it: • An account of sleep cycles and what each stage appears to do • Research on memory, learning and emotional regulation • Discussion of caffeine, alcohol, light and shift patterns • Scientific material presented without specialist vocabulary Written for general readers, students and health-conscious professionals; persistent sleep problems should be discussed with a qualified medical practitioner.
