Abstract
Cortisol is a key stress hormone that is implicated in a variety of physiological responses. Attenuated Cortisol Awakening Response (CAR) is associated with many negative health outcomes, but little research has investigated CAR and pain. The current study examines the association of CAR with experimental acute-pain ratings in healthy men and women. Attenuated CAR was related to greater pain intensity and unpleasantness ratings. Future research should examine this association across various pain populations.
