Relationships are one of the strongest everyday predictors of long-term health. A large review found people with stronger social ties had a 50% greater likelihood of survival over the periods studied. This piece is part of our guide to habits and learning.
How much do relationships affect health?
A 2010 meta-analysis in PLOS Medicine pooled 148 studies with 308,849 participants. It found "a 50% increased likelihood of survival for participants with stronger social relationships", and concluded that "The influence of social relationships on risk for mortality is comparable with well-established risk factors for mortality."
These were observational studies, so they show a strong and consistent link rather than proving that relationships cause longer life. People who are healthier may also find it easier to stay connected.
How can you build more connection into your week?
- Make it regular. A standing weekly call or walk is easier to keep than occasional big plans.
- Combine it with something you already do, such as exercising or eating with someone.
- Join something recurring: a class, team, choir or volunteer group gives repeated contact with the same people.
- Use an if-then plan. "After Sunday lunch, I will call my sister." The habit planner helps you write one.
