This book is about the urgent need to have time for health. It’s about why people don’t exercise, rest or eat healthy food even when they know they need to do so. Problems of combining work and family, entrenched gender inequality, and the unrelenting drive to be more efficient and do more for less, is making lack of time as important as lack of money for public health. Time has become a new health prescription needed to halt chronic diseases, 30 minutes of physical activity every day is a minimum, but this book argues against telling people to do more. It explains why it’s not laziness, ignorance or lack of motivation that’s the problem for unhealthy lifestyles and why so many people no longer have enough time for their health. The first two chapters introduce ideas about time and health, spanning economics, sociology, political economy and public health. The third connects lack of time to gender, social and health inequalities. The final chapter canvasses interventions and actions from the personal, to the workplace, in health promotion and urban design.
