We've all heard the old cliché-Laugh and the world laughs with you, mourn and mourn alone. According to a scientific study, happiness is contagious literally. If you surround yourself with happy people, have a profound and lasting effect on your own happiness.
According to an article by Maria Cheng of the Associated Press, a research paper published in a British medical journal concluded that happiness is contagious and that people spend in their joy, even the total number of foreigners.
The study was carried out by American researchers in a group of 4,700 subjects in Framingham, Mass. The study also found that the transfer of happiness can last up to one year.
The study indicated that happy people tend to be at the center of social networks and had many friends who were also happy. Have friends or close relatives of a person more likely to be happy and spread that happiness to the outside by three degrees, not only friends but also friends of friends.
One area of research that address was not the advent of social networks on the Internet. While it is believed that the social networks on the Internet may have the same effect, there is no evidence of this, because not exist when the 2003 survey. While it seems that social networking can help in the network can also be directed to contact (person to person) may be a necessary ingredient for this contagion of happiness to work.
It is also interesting that the effect was stronger with the friends of the same sex and that the effect is even stronger than having a happy couple.
In other research, Andrew Steptoe, professor of psychology at University College London is pleased that it also brings other benefits, including a protective effect on the immune system to produce fewer stress hormones. So not only you feel good to be happy, but you will actually be healthier.
There are other reasons why it may be wise to choose your social networks (friends) carefully. In an earlier study by the Harvard Nicholas Christakis and James Fowler of the University of California (the authors of this study) also found that obesity and smoking spread socially.
One of the interesting aspects of the study also adds to the old cliché that: mourn and mourn alone. The study also showed that grumpy people and much less negative effect on social networks more positive than the happiness of people. So while you may want to surround yourself with happy, you do not have to drop your grumpy friends. In fact, perhaps their joy is contagious to them.
An interesting side note in the study is that the sudden influx of money has almost no effect on happiness as happy to have friends. In a way, which is also supported by another of the old clichés of money does not buy happiness.
