Resilience or the capacity to “bend but not break” refers to the ability to maintain or regain psychobiological equilibrium during or after exposure to stressful life events. Specifically, resilience has been proposed as a potential resource for staving off pathological states that often emerge after exposure to repeated stress and that are related to alterations in circulating cortisol. The aim of this systematic review of the literature was to gather evidence related to the relationship between psychological resilience and cortisol levels in adult humans. An extensive systematic search was carried out following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) method in the PubMed and Web of Science databases. In total, 1256 articles were identified and, of these, 35 peer‐reviewed articles were included in the systematic review. We categorized findings according to (1) the short and long‐term secretion period covered by the cortisol matrices selected by studies and also according to (2) the differentiated diurnal, phasic (acute), and tonic (basal) components of the HPA output to which they refer and their relationships with resilience. Reported relationships between psychological resilience and distinct cortisol output parameters varied widely across studies, finding positive, negative, and null associations between the two variables. Notably, several of the studies that found no relationship between resilience and cortisol used a single morning saliva or plasma sample as their assessment of HPA axis activity. Despite limitations such as the great variability of the instruments and methods used by the studies to measure both resilience and cortisol, together with their high heterogeneity and small sample sizes, the evidence found in this systematic review points to the potential of resilience as a modifiable key factor to modulate the physiological response to stress. Therefore, further exploration of the interaction between the two variables is necessary for the eventual development of future interventions aimed at promoting resilience as an essential component of health prevention
