On care infrastructures and health practices: How people in health promotion programmes try to change their everyday life.

This paper contributes to challenging common behavioural or cognitive explanations for health and wellbeing outcomes, focussing on social practices through which people, with the help of other subjects, try to improve their health conditions. To renew the debate about health promotion, my work is placed at the intersection between the sociology of health and illness and science and technology studies, adopting the concepts of care infrastructures and health practices that are introduced in the next section. With this goal, my paper draws on a qualitative study concerning a Workplace Health Promotion programme aimed at reducing the risks of Type-2 diabetes and cardiovascular diseases among sedentary workers. The findings illustrate how a care infrastructure in the field of health promotion is designed, put to work, repaired and 'put aside' in relation to two health practices ('doing physical activity' and 'following the Mediterranean diet'). Drawing on the presented case, I show how the change in daily habits in the fields of nutrition and physical activity is a collective effort involving different spheres of life, connecting human and non-human elements and bringing out affective intensities among them.
