Smiling has been previously shown to improve stress responses. We replicated and expanded this work by testing whether smiling helps with a potent real-world stressor: a vaccination-like needle injection. We also extended past research by examining grimacing, a facial expression known to naturally occur during stress and pain and one that shares some of the same facial action units as smiling. Participants (n = 231; …
