#Socialhealth

A groundbreaking 2025 study using data from a large US longitudinal cohort finds that people with stronger and more consistent social connections tend to show signs of slower biological aging and lower inflammation. The findings, published this year in a biomedical data framework, add to a growing body of evidence that our social lives don’t just influence how we feel; they appear to influence what happens inside our bodies over decades. While researchers caution that the study is observational and cannot prove causation, the results illuminate possible physiological pathways through which friendships and family ties could affect health, especially as people move through middle age toward older adulthood.
