Relationships make us happy – and healthy
A Harvard study spanning nearly 85 years finds that strong relationships are the single biggest predictor of happiness and health, more than wealth or fame. The research, part of the Harvard Study of Adult Development, shows that social fitness—actively investing in relationships—is crucial for well-being across a lifetime.
Background
- The article reports on the Harvard Study of Adult Development, one of the longest-running longitudinal studies of human well-being (ongoing since 1938). It has tracked hundreds of participants (and later their children) across their entire lives, collecting medical records, psychological surveys, and interviews.
- Key finding: the quality of people's close relationships — not cholesterol levels, exercise, or wealth — is the strongest predictor of happiness, physical health, and longevity. Loneliness is as damaging as smoking or alcoholism.
- Robert Waldinger, the study's current director (a psychiatrist at Massachusetts General Hospital/Harvard Medical School), has popularized these findings in a TED Talk and a book ("The Good Life").
- This matters because it challenges the biomedical / self-optimization framing of health dominant in English-language media: it argues that social fitness (investing in relationships) is as important as physical fitness for long-term well-being.
