Why you should turn that frown upside down: Smiling IS infectious

It’s not just yawning – smiling and frowning are contagious too! We mimic other people’s expressions to show empathy.

  • Scientists say we unconsciously ‘simulate’ the facial expressions of others
  • Studies have shown it may help us understand how someone else feels
  • People who cannot mimic a facial expression struggle to detect subtle cues
  • Further research could help the treatment of social disorders like autism
