Nevertheless, due to the lack of prospective studies linking stress responses with physical health outcomes in people with T2D, it is not yet known whether heightened IL‐6 responsivity to stress is health damaging in T2D, as observed in healthy samples, since endothelial dysfunction and biological dysregulation are already established in this population (Ghiadoni et al., 2000; Steptoe et al., 2014). Here, IL6 is linked to endothelial dysfunction.
