Overview
What is it?
Social connections refer to the relationships and interactions individuals have with others, which can include family, friends, and community ties. These connections are naturally occurring and are essential for emotional, informational, and instrumental support. They encompass the structure, function, and quality of relationships, all of which contribute to overall health and well-being .
How does it work?
Social connections improve longevity by influencing both biological and behavioral mechanisms. They activate the sympathetic nervous system (SNS) and hypothalamic-pituitary axis (HPA), which help regulate stress responses, reduce inflammation, and promote healthier behaviors like physical activity and better sleep. Additionally, social connections provide emotional support, which can buffer against the negative effects of stress and improve mental health .
What are the benefits?
Social connections are linked to a 50% increase in the odds of survival, as shown by meta-analytic data from 148 studies. They reduce the risk of premature mortality, chronic diseases, and mental health issues. Strong social ties are also associated with improved physical and mental health, reduced risk of cognitive decline, and lower all-cause mortality. Furthermore, they enhance neighborhood safety, resilience during crises, and access to services .
Effectiveness
What does the research say?
Research consistently shows that social connections significantly improve longevity. For example, loneliness is associated with a 26% increased risk of earlier death, social isolation with a 29% increased risk, and living alone with a 32% increased risk. Conversely, being socially connected increases the odds of survival by 50%. The Harvard Study of Adult Development found that satisfaction with relationships is the greatest predictor of longevity and well-being .
Side Effects
None reported
The research does not mention any negative side effects of social connections. However, it is important to note that unhealthy or toxic relationships could potentially have adverse effects, though these are not discussed in the reviewed studies .
