World Smile Day is celebrated every year on the first Friday of October, this time it falls on 6 October. Its purpose is to promote goodwill and positivity through smiling. Harvey Ball, a commercial artist from Worcester in the state of Massachusetts, USA, started celebrating this day. He created the iconic smiley face in the year 1963. He wanted that just by smiling you can spread kindness and happiness. We should also smile in every moment of our lives because it can have many innumerable benefits.

Benefits of smiling
1. Mood will be better

When you smile, the brain releases happy hormones, which include serotonin, dopamine, and endorphins. These are natural pain relievers. It doesn't matter whether you are smiling from your heart or smiling forcibly, it will improve your mood.

2. Freedom from stress
It has been proven in many studies that if you smile, you will easily get rid of stress and depression. Smiling keeps your heart rate and blood pressure under control, no matter how many difficulties you are surrounded by. Actually, by smiling, our brain releases neurotransmitters that cause cortisol, adrenaline, and norepinephrine.

3. Immunity will be boosted
Smiling releases serotonin hormone in our brain which is not only responsible for happiness but also strengthens our immunity. It also produces monocytes and lymphocytes of white blood cells which help in fighting infections.

4. Others also benefit
Smiling fulfills the purpose of World Smile Day, that is, if you smile, positive vibes will be transferred to another person. This will make the other person feel happy. If you remain happy then your own and other person's work productivity will increase.
