Frown When You're Down
Which comes first, the look or the emotion?
(HealthDayNews) -- Do you frown because you're upset or do you become upset because you frown?
Both, says author Jeanne K. Hanson in her book Your Amazing Body, from Headaches to Sweaty Feet and Everything in Between.
Try frowning for a minute or so, and you'll start to feel upset . That's because the corrugator muscle, which runs across the top of your eyebrows, is the major one responsible for all unhappy expressions, including frowning, glaring and squinting.
The corrugator muscle pushes your eyebrows down and closer together and squeezes your eyeballs a bit.
So be aware that whatever expression you decide to wear will influence how you feel. And put on a happy face.
