We all do it. Put on a happy face throughout the day, whether it be genuine or not. 

Maybe you laughed at a joke. Smiled at a baby. Or just, simply, faked it to be polite. The bottom line is, no matter why or how you smile, it’s an exceptionally good thing for your health. In fact, studies have shown that smiling can help you live better – happier – longer. 

Smiling yet? Read more to see how boosting your smile can help you rev up your health.

1. Gift yourself a better mood
When feeling down in the dumps or negative, wearing a smile can perk up your mood. That’s because every time you smile, you activate good-feeling messengers to your brain. While these messengers can make you feel a range of emotions, your smile auto-selects happiness, releasing dopamine, serotonin and endorphins that take you one step closer to a better day. 

2. Lower blood pressure and heart rate
While it’s true that smiling through laughter causes an initial increase in heart rate, it’s followed by a period of muscle relaxation, which actually decreases your heart rate and blood pressure. Making it a habit to schedule a good laugh each day can help reduce your risk of developing heart disease in the long run.

3. Dissolve stress away
Now that you’ve moved your heart rate down with positive feelings, you’ve also lowered your overall stress level. Keeping stress away makes for a healthier body and a happier you. Flex your smile muscles often for consistent results.

4. Strengthen your immune system
According to the Mayo Clinic, positive thoughts and laughter release signaling molecules in your brain that fight illnesses, while negative thoughts decrease your body’s immunity. For that reason, medical settings often strive to feature positive environments for their patients. Doing so promotes healing and should be prescribed morning, noon and night. 

5. Live a longer life
No need to search far for the power of longevity. A 2010 study that focused on photos of major league baseball players found that smiling and positive emotions are associated with longer life spans. Next time you need to validate your hard work for a longer life, just look in the mirror and smile.

6. Build your relationships
We tend to gravitate to people who smile, partially because they often make it easier to maintain the friendship. In fact, one study revealed that people who display positive emotions, have more stable marriages and interpersonal skills. This also goes for better bonding and cooperation within a group setting, too, enhancing relationships with people in the workplace.

7. Fight pain 
The endorphins your release when you smile are 100% natural painkillers produced by your own body, without the negative effects of medication. One study found that social laughter significantly increases your pain threshold, creating a higher pain tolerance. Try out the theory yourself the next time you face routine bloodwork, an injury or ailment.

Make the most of your smile

Skip the news
Many of today’s world topics can take the steam out of anyone’s smile. Turn off the chatter and tune into the positive with good music or people you love.

Be with happy people
Smiling is contagious. So, find a friend with a sparkling smile and hang out for a while. Build the momentum by asking others to join, sharing the sunshine and peak serotonin levels.

Watch something funny
Finding the right movie comedy or blooper video may be all you need to tickle your funny bone. Remember, laughter is the best medicine – and now we know why! 

Fake a smile — your brain doesn’t know the difference! 
Even if you don’t feel like smiling, do it anyway. You’ll fool your brain into releasing endorphins and benefit from the good vibes they can bring. Repeat often.
