A smile is a universal sign of happiness and friendship, so don’t be afraid to show your pearly whites! Humans are the only species that uses the smile, in various forms, to demonstrate happiness. Even visually impaired children who have never seen a smile, have the same kinds of smiles that sighted people do. This tells us that smiling is something preprogrammed into humans. This behavior is not learned but instinctual.
We smile when we are happy, but can forcing ourselves to smile make us feel happy even when we are not? Neurologists have discovered that the physical act of smiling triggers chemical reactions in the brain that boost our moods, lower stress, and even strengthen our immune systems. So don’t just smile during the month of June; do it all year round!
