Study after study has found that social support is key when it comes to fighting stress and staying happy. And there’s a chicken and egg relationship when it comes to the role of humor: Sharing a positive sense of humor helps make you more approachable and likeable, which helps you build and maintain a thriving social network. And conversely, lots of social interaction helps generate a lot of humor. According to Robert R. Provine, author of Laughter: A Scientific Investigation, “Laughter is the quintessential human social signal. Laughter is about relationships.” Provine’s research found that people laugh 30 times more when they are around other people than when they are alone. So the next time you are feeling stressed take a cue from the game show Who Wants To Be A Millionaire? and use a “laugh-life” by phoning a friend who you know will make you laugh and help you find the humor in a difficult situation.
