How Social Connections and Strong Friendships Boost Long-Term Health and Longevity
- I found that people who were more satisfied with their friendships and relationships also tended to report better mental and physical health.
Fulfilling friendships and close personal ties are strongly linked to better mental and physical health across 22 countries, according to a comprehensive global study. Data from more than 200,000 adults shows that satisfaction with adult friendships and relationships offers measurable health benefits, while positive childhood family ties play a secondary role in overall well-being.
Global Study Links Social Connections to Health Across 22 Countries
The research analyzed data from 204,907 adults aged 18 and over, sourced from the first phase of the Global Flourishing Study. Led by Dr. Veli Durmuş from Kütahya Health Sciences University in Türkiye, the project spanned diverse geographic regions including the UK, US, Australia, Argentina, Brazil, Germany, Spain, India, Japan, Egypt, Nigeria, South Africa, and Mexico. According to Dr. Durmuş, the findings demonstrate that social connections deserve a recognized place in public health planning.
Participants in the survey rated their satisfaction with friendships and relationships, while also evaluating their own mental and physical health on a scale from poor to excellent. The study controlled for variables such as income and education to isolate the impact of social ties. Results showed that individuals reporting high contentment with friendships consistently reported superior overall health outcomes.

Childhood Ties and Adult Environment Factors
While adult friendships showed a strong correlation with well-being, childhood relationships with mothers and fathers displayed a similar, though weaker, pattern. Dr. Durmuş noted that early family relationships are associated with later health, but they do not tell the whole story. As people navigate changing social environments throughout life, adult partnerships and friendships continuously modify or strengthen the influence of earlier experiences.
The study also identified demographic patterns within the data. Mental health scores dipped among participants in their mid-thirties to late forties compared to younger adults aged 18 to 34, but rose again among those aged 65 and older. Additionally, sufficient financial resources, marriage, and religious identification—particularly Islam—correlated with higher mental and physical health scores.
