It will benefit your health
Smiling activates the release of neuropeptides that work toward fighting off stress. The feel-good neurotransmitters — dopamine, endorphins and serotonin — are all released when a smile flashes across your face as well. This not only relaxes your body, but it can also lower your heart rate and blood pressure. Finally, the serotonin release brought on by your smile serves as an anti-depressant/mood lifter. 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 will improve your perception at work
Smiling is like taking a breath, a break that allows your brain to perceive a situation from another vantage point. Smiling can help you to feel more positive and respond better to challenging situations.
It will enhance your social and romantic life
Smiling sends signals that you are enjoying yourself and the other person. A smile is a sign of contentment, positivity and happiness; all of which the majority of people are more attracted to. So you’re more likely to attract people to you if you have a smile on your face.
