Forcing a grin has been found to reduce heart rate and to heighten mood. Chopsticks were used to induce an artificial smile in three groups of subjects. The fake smiles were described as neutral (first image), standard (second image), or Duchenne (third image). All three groups endured stress better than the control groups. The most successful group had assumed the Duchenne smile (third image) which is more realistic than the other fakes because it entails a wrinkling effect around the the eyes — more closely resembling a real smile.
