Every year, March 20 is observed as the International Day of Happiness. As the name suggests, it is solely dedicated to the most favourite feeling in the whole wide world. It aims to facilitate the importance of the same in the overall well-being of humans everywhere.

A smile can lighten the whole environment and make each present there happy, Down below are the reasons why all of us should smile and its benefits. 

Smiling Makes Us Attractive

We are naturally drawn to people who smile. There is a real physical attraction factor linked to the act of smiling. Not surprisingly, more severe or negative facial expressions like frowns scowls and grimaces actually work in the opposite manner, effectively pushing people away. Instead, use the attraction power of your smile to draw people in.

Smiling Relieves Stress

Stress can permeate our entire being, and can really show up in our faces. Smiling not only helps to prevent us from looking tired, worn down, and overwhelmed but can actually help reduce stress.

Believe it or not, smiling can reduce stress even if you don`t feel like smiling or even if you fake smiling.3 When you are stressed, take the time to put on a smile. You and those around you will reap the benefits.

Smiling Elevates Our Mood

Next time you are feeling down, try putting on a smile. There`s a good chance your mood will change for the better. Smiling can trick the body into helping you elevate your mood because the physical act of smiling actually activates neural messaging in your brain.

A simple smile can trigger the release of neural communication boosting neuropeptides as well as mood-boosting neurotransmitters like dopamine and serotonin. Think of smiling like a natural anti-depressant.

Smiling Is Contagious

How many smiles have been described as having the power to lighten up the room? While it is certainly a beautiful sentiment, it carries a hint of truth. Smiling not only has the power to elevate your mood, but it can also change the moods of others and make things happier.

The part of your brain that is responsible for your controlling the facial expression of smiling is an unconscious automatic response area. Meaning that smiling can be completely unconscious, particularly when it comes to our habit of mimicking another person`s smile. Yes, it is scientifically proven that smiles are "contagious."

Smiling Boosts Your Immune System

Smiling can also boost your overall health. The act of smiling actually helps the human immune system to function more effectively. It is thought that when you smile, immune function improves because you are more relaxed (thanks to the release of certain neurotransmitters).6

In addition to taking precautions like washing your hands, why not try to prevent the cold and flu by smiling?

Smiling Lowers Your Blood Pressure

When you smile, there is a measurable reduction in your blood pressure. Give it a try if you have a blood pressure monitor at home. Sit for a few minutes, take a reading. Then smile for a minute and take another reading while still smiling. Do you notice a difference?

Smiling Makes Us Feel Good

Studies have shown that smiling releases endorphins, natural painkillers, and serotonin.8 Together these three neurotransmitters make us feel good from head to toe. Not only do these natural chemicals elevate your mood, but they also relax your body and reduce physical pain. Smiling is a natural drug.

Smiling Makes You Look Younger

Not only can smiling make you more attractive it can also make you look more youthful. The muscles we use to smile also lift the face, making a person appear younger. So instead of opting for a facelift, just try smiling your way through the day—you`ll look younger and feel better.

Smiling Makes You Seem Successful

Studies have shown that people who smile regularly appear more confident,9 are more likely to be promoted, and are more likely to be approached. Try putting on a smile at meetings and business appointments. You might find that people react to you differently.

Smiling Helps You Stay Positive

Try this test: Smile. Now try to think of something negative without losing the smile. It`s hard, isn`t it?

Even when a smile feels unnatural or forced, it still sends the brain and ultimately the rest of our body the message that "Life is Good!" Stay away from depression, stress, and worry by smiling.
