During stress the body’s two main stress systems, the sympathetic-nervous-system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis are activated to help organisms adaptively cope with the stressful situation. Previous studies on stress and health have found strong evidence of dysregulated SNS or HPA axis functioning in disease states. However, given the complex nature of the stress system these investigations have largely linked the activity of either the SNS, or the HPA axis to (psycho-) pathological outcomes. Stress also has important effects on emotional and affective responses. Thus while psychological processes are also hypothesized to cross-talk with the physiological responses, empirical investigations of how all these components interact during conditions of stress, and how they contribute to pathological outcomes are largely missing. Over three original studies we combined pharmacological challenges with acute stress induction, to systematically manipulate the stress systems and investigate the interactions among the various components. Findings from these studies contribute towards our understanding of how the physiological and psychological stress systems interact in men and women during stress.
