Connection Is a Health Factor
When we think about longevity, we usually think about diet and exercise. But research shows that social connection is one of the most powerful predictors of a long, healthy life.
What the Research Shows
- A major analysis of 148 studies found that people with stronger social relationships had about a 50% greater likelihood of survival over the study periods compared with those with weaker connections
- The Harvard Study of Adult Development, which has followed people for more than 80 years, found that close relationships were among the strongest predictors of health and happiness in later life
- In 2023, the U.S. Surgeon General issued an advisory on the health risks of loneliness and isolation, linking them to higher risk of heart disease, stroke, dementia, depression, and early death
The effects of social isolation on mortality risk have been compared to other well-known risk factors like smoking and physical inactivity.
Why Connection Matters
- Lower stress: Supportive relationships buffer the effects of stress
- Healthier habits: Friends and family can encourage exercise, healthy eating, and medical care
- Mental health: Connection protects against depression and anxiety
- Brain health: Social engagement keeps the mind active and may lower dementia risk
- Purpose: Relationships give life meaning, which is also linked to longevity
Ways to Build Connection
- Schedule regular time with friends and family
- Join a club, class, faith community, or volunteer group
- Exercise with others—walking groups, fitness classes, or sports
- Reach out to someone you haven't talked to in a while
- Put away phones during meals and conversations
- Consider adopting a pet, which can encourage activity and social interaction
Quality Over Quantity
