Taking a critical perspective, as we do in this book, involves going beyond the surface appearance of an idea or phenomenon to determine why it is the way it is (Baum, 2015). For (critically oriented) health psychology, this means scrutinising health-related issues through a lens that questions underlying assumptions, power dynamics, and social structures. It also means questioning our very understanding of the notion of health, which we frequently take for granted, and which is the focus of this chapter. The questions that may spring to mind are: What is the point of recognising and unpacking different, changing understandings of health and illness? And, Why is taking this critical perspective necessary or valuable? This chapter tackles these questions.
