The way we smile - or not - is a powerful communication tool that significantly influences how we're perceived by others. Countless studies demonstrate that we appear friendlier, more attractive, more confident, more competent, younger and more likeable when we smile. 

Smiling teachers are more perceived to be more effective than nonsmiling teachers. Smiling employees are perceived to be more trustworthy. Smiling servers not only receive bigger tips, but guests rate the service, food, and overall dining experience better than when served by a nonsmiling server. 

It turns out that the power of smiling isn’t just social science; it’s also neuroscience. Smiling – and seeing someone else smile at you – actually changes the brain. It increases the production of happy chemicals like dopamine, serotonin, and endorphins.

Dopamine: the reward and pleasure chemical activates the pleasure center of the brain

Serotonin: a mood stabilizer that affects appetite and digestion

Endorphins: natural pain relievers that elevate mood and reduce stress

This neurotransmitter cocktail puts the brain in a happy and relaxed state creating the optimum conditions for a positive experience.
