Effect of Social Media Use on Salivary Cortisol and α-Amylase Levels (©2020 Anosha Zanjani; used with permission). A brief period of social media use increased salivary markers of stress in depressed adolescents. Salivary cortisol is an index of hypothalamo-pituitary-adrenal (HPA) activation and noradrenergic activity. Salivary α-amylase is an indirect measure of sympathetic-adreno-medullary activity and central norepinephrine activity.
