Smiling a little easier these days? The Philadelphia Inquirer recently ran a story about the psychological effects of our thriving local sports teams. The Eagles are undefeated, the Phillies just advanced another round in the playoffs, and the Union have home-field advantage heading into the playoffs.

The effects? Psychologists say we’re collectively happier when our teams do well, even if sports aren’t central to daily life (and even if you don’t care about sports at all).

“Happiness is contagious,” said Eric Zillmer, a clinical psychologist and Drexel University professor who teaches courses on happiness and sports psychology. “That’s the beauty of these events that are happening right now. You just can’t help but be giddy.”
