The Performers Fitness Book of: Sleep - Tapa blanda

Sinopsis

Sleep - An absolute necessity. Probably more important than many of us realise. In terms of health and fitness, as important as diet or exercise. For those who know very little about the subject, maybe doze off at the mere mention of it, this book may open their eyes. For those who know more, they may learn something new. In addition to informing you about the merits of sleep, this book also provides techniques and strategies to help you improve that half (or, at least, third) of your life. Let 40 winks be your minimum!
