This is a detailed analysis of how understanding of health management past, present and future has transformed in the digital age. Since the mid-20th century, we have witnessed 'healthy' lifestyles being pushed as part of health promotion strategies, both via the state, and through health tracking tools, and narratives of wellness online. This marks a seismic shift from a public welfare state responsibility for health towards individualised practices of digital self-care. Today health has become representative of 'lifestyle correction' which is performed on social media. Putting the spotlight on neoliberalism and digital technology as pervasive tools that dictate wellness as a moral obligation, Rachael Kent critically analyses how users navigate relationships between self-tracking technologies, social media, and everyday health management.
