*WHY does smiling make you feel better?* Your body immediately starts producing endorphins when you smile, even when you force yourself to do so. This sudden change in mood makes you feel better and helps relieve stress. This principle was discovered in the 1980s and has been confirmed by a number of studies. But studies also reveal the flip side: frowning makes people feel unhappy. Studies show that it's enough to see a smiling friend or girlfriend, and one involuntarily begins to do the same. *©️Glinax STEAM Institute*
