About The Book

THE #1 SUNDAY TIMES BESTSELLER

Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.

In this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves into everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.

    CHANGES TO SERVICE: Signing for and receiving items

    In order to protect both the Royal Mail team and customers as much as possible, Royal Mail are minimising contact between their staff and customers. They will not be handing over their hand-held devices to customers to capture signatures but instead log the name of the person accepting the item.

    Additionally, for all customers where they need to deliver any item that won’t fit through your letterbox, they will place your item at your door. Having knocked on your door, we will then step aside to a safe distance while you retrieve your item. This will ensure your item is delivered securely rather than being left outside.
