Editorial: Psychophysiology of stress

Stress is a multifactorial complex phenomenon where organic resources are mobilized to deal with a real or perceived threat (Cohen et al., 1983). The stress response is one of the most important phylogenetic coping mechanisms that have allowed humans to successfully adapt to highly demanding and potentially dangerous contexts (Hadany et al., 2006; Korzan and Summers, 2021). The intrinsic neurobiological mechanisms involved in the stress response have not changed much in the last stages of the evolution of the human being, prominently including the hypothalamic-pituitary-adrenocortical axis and the autonomic nervous system (Ulrich-Lai and Herman, 2009;McEwen et al., 2015; Cohen et al., 2016). In contrast, our social context has changed dramatically recently in evolutionary terms.
