Book excerpt: This book explores the unique contribution that critical communication studies can bring to our understanding of health. It covers several broad themes: representing and mediating health; marketing and promoting health, co-producing health; and managing health crises and risks. Chapters speak to moral and social regulation through health communication, technologies of health, healthism and governmentality. They engage with historical and contemporary issues, offering readers theoretically grounded perspectives. At base, the book explores what a critical communication approach to health might look like, revealing in important—and sometimes surprising—ways how communication sits at the centre of understanding how health is constructed, contested, and made meaningful.
