Researchers from the University of California found that people using Facebook to build and strengthen social ties live longer. Their findings are presented in an article published in the journal Proceedings of the National Academy of Sciences.
The authors work for six months studied the Facebook activity in several million California residents born in the period from 1945 to 1989. Found that logged in the social network lived longer than those who did not have an account. The risk of dying to a user Facebook was reduced by 12 percent.
The researchers also estimated the number of friends, number of photos and messages, as well as the frequency of status updates of users. While the researchers took into account gender, age, marital status and duration of use Facebook.
It turned out that more active in social networks people also lived longer. However, the high duration of life was characteristic of those users that wrote the average number of messages.
Scientists believe that human activity in Facebook and other social networking really allows him to live longer. However, another explanation is possible. For example, healthy people with high income is attractive to other users, which improves their communication. At the same time not having access to social networks can belong to the group with low income and do not receive adequate medical care.
