Digital Weathering: How Social Media Platforms Organize Chronic Stress Exposure During Adolescence

Research on social media and adolescent mental health has focused largely on individual use patterns, asking how much young people use platforms rather than examining how platform design organizes what they are exposed to. We introduce digital weathering, a theoretical framework that extends the weathering hypothesis to algorithmically curated social media environments. The weathering hypothesis shows that chronic exposure to structural disadvantage becomes biologically embedded through cumulative physiological wear. We propose that social media platforms function as structural environments that organize exposure to chronic stress during adolescence through three mechanisms. Algorithmic sorting classifies users and distributes content unequally across populations. Persistent connectivity compresses recovery between stress exposures. Engagement amplification prioritizes emotionally arousing content, increasing exposure intensity. These mechanisms interact with the heightened biological sensitivity of adolescence to produce differential accumulation of physiological wear across populations. We predict that adolescents with equivalent platform usage will show systematically different patterns of biological stress accumulation, reflecting algorithmically organized exposure rather than individual behavior. We discuss implications for measurement, intervention, and platform design.
