Mood & Perception
Natural Stress Reduction
Smiling triggers the release of neurotransmitters such as dopamine, endorphins, and serotonin, which elevate mood and alleviate stress. Even a deliberate smile can initiate this effect, promoting relaxation and reducing anxiety. (Psychology Today)
A 2024 study led by Dr. Sebastian Korb at the University of Essex demonstrated that even brief, weak smiles can make neutral faces appear happier. Researchers used electrical stimulation to induce smiles and found that participants perceived ambiguous facial expressions as more joyful when they themselves were smiling.

A 2020 study from the University of South Australia, led by Dr. Fernando Marmolejo-Ramos, revealed that the act of smiling can trick the mind into perceiving the world more positively.
