Why You Cry When Your Favorite Team Wins

Your eyes are bone dry when you’re hurt or sad. But the night your team took home the title? Waterworks. What’s the deal with that?

For the first time, researchers have looked into this odd “tears of joy” phenomenon. The Yale University study team calls it a “dimorphous display”—meaning your expressions and reactions don’t seem to match up with how you’re feeling. Other examples include smiling when you’re frustrated, or making sad faces or sounds when you see an adorable baby.
