Study links loneliness to health risks and cautions against medicalizing the social issue

A University of Michigan study published in *Social Problems* documents that chronic loneliness and social isolation are linked to higher disease risk, premature death and rising healthcare costs. Prior research cited in the paper equates a lack of social connection to smoking 15 cigarettes a day, and shows that loneliness, isolation and living alone each raise the risk of premature death by roughly 30%. The study also estimates that Medicare spends about $6.7 billion annually on elder care related to social isolation.

The authors argue that framing loneliness as a medical problem shifts responsibility from society to the healthcare system, which cannot rebuild community ties or change work‑hour structures. “Not everything that relates to health belongs in healthcare,” said doctoral student Sofia Hiltner. She warns that the “logical leap” of assuming the healthcare system should fix loneliness may crowd out other, upstream solutions.

Hiltner hopes the research will prompt policymakers to consider broader social interventions rather than relying solely on clinical screening and treatment.
