A study published in the July PLoS Medicine is getting a lot of press for its conclusion that strong social networks are related to increased lifespan.
The meta-analysis of 148 studies involving 308,849 people found that those with stronger relationships were 50 percent??more likely to survive over 7.5 years of follow-up. What’s more, the researchers reported that a lack of strong social ties is as bad??healthwise as drinking or smoking, and worse than not exercising or being obese.
But although the association between strong social ties and improved longevity seems robust, other factors could be at play, and applying the findings in clinical practice could be difficult. And sorry, Facebook fanatics: Online “friendships” aren’t thought to count as much as in-person ones do. (PLoS Medicine, New York Times, TIME, The Atlantic)
