This article explains how the most recommended treatment for obstructive sleep apnea, the continuous positive airway pressure device, acts and interacts with users’ bodies, sleep partners’ bodies, and cultural discourses to produce emotions and practices that generate the subjectivity of a disabled or abled person. Drawing upon in-depth interviews with OSA patients, this article illustrates how introducing CPAP devices into patients’ lives may disturb their sleep and breathing, diminish their independence, disfigure their appearance, and problematize intimacy with bed partners, thereby (...) disrupting both the fleshy body and the culturally preferred image of a healthy, independent, and attractive individual.
