In the age of datafication, our lives are increasingly created and managed online. This path seems irreversible and greater attention to the use and structures of the mass media, especially new media, seems equally essential. In this scenario, in which the main social media and their functions have assumed a predominant status, a higher consideration is placed by the research that observes the possible implications. This work investigates some negative consequences related to the logics of new media, including social media addiction and objectification attitudes, and the role of social media literacy as an educational approach to prevent and reduce these conditions, with a view to training people aware from an intrapersonal, intersubjective and socio-emotional point of view in favor of civic and participatory strengthening.
