Improving Our Mood and Health With Smiles
THE OLD LINE “it takes fewer muscles to smile than frown” isn’t actually true. It takes at least ten muscles to smile but as few as six to frown, so maybe the saying should be something like “you burn more calories when you smile than when you frown!” instead. However, getting a better workout isn’t the only benefit we get from smiling! The Feedback Loop Between Smiling and HappinessObviously, we smile when we’re happy, but evidence shows that the very act of smiling might make us feel happier. Smiling is so closely linked to the feeling of happiness in our brains that even a fake smile can release endorphins — the feel-good hormone — and make us feel better. The next time you’re having a rough day, try flashing a smile and see if that helps a little! We Reduce Pain and Stress by SmilingThose endorphins we get from smiling can do a lot of helpful things besides just contributing to a better mood. Short-term, endorphins help to reduce pain and relieve stress because they function in a similar way to painkillers (except without the side effects). A 2012 experiment tested how long it took subjects’ heart rates to return to normal after completing a stressful task, and the smiling subjects recovered faster. The way the experiment worked was that the non-smiling group had to hold a pencil between their lips while they did the task (forcing a more pout-like expression), while the smiling group had to hold the pencil between their teeth (forcing more of a smile).
