In this project, we investigate the kinds of values, norms, and beliefs that healthcare professionals, decision-makers, and citizens hold regarding health, illness, medicine, and healthcare, as well as how these influence medicine’s ability to understand, adapt to, and participate in the broader societal sustainability transformation. A central concept for understanding this is medicalization, which we examine using theoretical tools from the Study of Religions. We are particularly interested in the boundaries through which matters, phenomena, and practices related to health, medicine, and healthcare are set apart and made special – or sacred – and how these processes are connected to the sustainability of healthcare.
