SCIENCE-BACKED BENEFITS OF SMILING Smiling elevates mood, relieves stress, strengthens immune function, and increases pain resilience. • Elevate Mood (Facial Feedback Effect) We smile when we are happy, but research shows smiling itself makes us feel happier. A 2019 meta-analysis of 138 studies [1] confirmed that smiling—even intentionally—activates neural pathways that improve emotional well-being [2]. • Relieve Stress Taking a short break to put on a smile helps lower stress responses and cortisol levels [3], helping you feel calmer throughout the day. • Support Immune Health & Reduce Pain Smiling triggers the release of endorphins—your body’s natural painkillers [5]—while relaxing neurotransmitters support immune function [4]. DISCLAIMER Although smiling has many scientifically proven benefits for mental and physical health, Egao does not replace treatment by a qualified healthcare professional in the case of illness.
