About The Book

The #1 New York Times bestselling author of The FastDiet and “one of the world’s leading journalists covering nutrition and health” (Dr. Valter Longo, director of the University of Southern California Longevity Institute) presents a “well written, well researched, and very practical” (Dr. Tim Spector, professor at Kings College, London) science-based sleep program designed to improve brain function, support weight loss, boost your mood, and reduce stress.

Getting a good night’s sleep is everyone’s daily goal. After all, it reduces your risk of depression, helps you fight chronic disease, improves your memory, and it just plain feels good. But why is it that so many of us struggle to get the necessary seven to eight hours a night?

In Fast Asleep, Dr. Michael Mosley brings together the latest, groundbreaking science to explain exactly why it is so important that we regularly get enough sleep. Prone to insomnia, he has taken part in numerous sleep experiments and tested every sleep remedy. Combining personal insight and in-depth research, he explains why so many of us struggle with sleep, what works and what doesn’t, and shares his own myth-busting program to help you achieve a good night’s rest.

Filled with fascinating case studies, fifty delicious, sleep-promoting recipes, and more, Fast Asleep is a complete resource that offers a range of tools for combating fatigue and tiredness. Simple, effective, and life-changing, this book explores the science of dreaming, explains why gut health and meal times matter, and reveals tips and tricks to help you not just to sleep better, but to reduce stress levels and feel happier and healthier in general.
