How smiling affects your brain
It’s a rough morning. First, my alarm doesn’t go off. Then I’m late getting my son to school, because another driver decides to roll into me. It doesn’t damage my car, but it completely wrecks my mood. Then I get to my doctor’s appointment, only to realize that I’m an hour early. Just great. It must be a case of the Mondays!
I decide to pop into a little French café around the corner to grab a cup of tea while I’m waiting. As I sit under my little gray cloud, my pretty, young server, Colette, flashes me a dazzling smile that sticks there for the entire interaction. I can’t help but smile back. In fact, I even catch myself smiling while washing my hands in the bathroom.
Suddenly, my day doesn’t seem so bad. I finish my tea and head to my appointment equipped with a grin on my face, feeling as though I’ve slipped on a pair of rose-colored glasses.
Today’s lesson? It turns out that when I smile, the world smiles back.
Scientists and spiritual teachers alike agree that the simple act of smiling can transform you and the world around you. Current research (and common sense) shows us that a smile is contagious (1). It can make us appear more attractive to others. It lifts our mood, as well as the moods of those around us. (Merci, Colette.) And it can even lengthen our lives (2). So before you read on, slap a nice, genuine smile on that face of yours. You’ll thank me later.
For starters, smiling activates the release of neuropeptides that work toward fighting off stress (3). Neuropeptides are tiny molecules that allow neurons to communicate. They facilitate messaging to the whole body when we are happy, sad, angry, depressed, or excited. The feel-good neurotransmitters—dopamine, endorphins and serotonin—are all released when a smile flashes across your face as well (4). This not only relaxes your body, but it can also lower your heart rate and blood pressure.
The endorphins also act as a natural pain reliever—100-percent organic and without the potential negative side effects of synthetic concoctions (4).
Finally, the serotonin release brought on by your smile serves as an anti-depressant/mood lifter (5). Many of today’s pharmaceutical anti-depressants also influence the levels of serotonin in your brain, but with a smile, you again don’t have to worry about negative side effects—and you don’t need a prescription from your doctor.
It also explains the 2011 findings by researchers at the Face Research Laboratory at the University of Aberdeen, Scotland. Subjects were asked to rate smiling and attractiveness. They found that both men and women were more attracted to images of people who made eye contact and smiled than those who did not (6). If you don’t believe me, see how many looks you get when you walk outside with that smile you’re wearing right now. (You’re still smiling like I asked, right?)
In a Swedish study, subjects were shown pictures of several emotions: joy, anger, fear, and surprise. When the picture of someone smiling was presented, the researchers asked the subjects to frown. Instead, they found that the facial expressions went directly to imitation of what subjects saw (8). It took conscious effort to turn that smile upside-down.
So if you’re smiling at someone, it’s likely they can’t help but smile back. If they don’t, they’re making a conscious effort not to.
Looking at the bigger picture, each time you smile at a person, their brain coaxes them to return the favor. You are creating a symbiotic relationship that allows both of you to release feel-good chemicals in your brain, activate reward centers, make you both more attractive, and increase the chances of you both living longer, healthier lives.
My morning started as a complete mess.
Anyone in my shoes would have been frowning by the time they hit that café. We can’t always control what happens to us, but I am 100 percent confident that gracing your face with a grin can seriously change your internal and external experience.
Your smile is something that should be worn often, so make it a priority to surround yourself with people, places, and things that brighten your day.
Vow to be the positive, happy person in your group of friends. Watch funny movies often, and be sure to look people in the eye and show them your pearly whites.
The World is Simply a Better Place When You Smile😊
