Bengaluru: On #WorldSmileDay, here are some reasons for you to say cheese! 

1.    Smiling Boosts Your Immune System
This is one good reason as to why you shouldn’t hold yourself back from smiling. When you smile, certain neurotransmitters are released, thereby improving your immune function. 

2.    Smiling Lowers Your Blood Pressure
Another good reason, isn’t it? When you smile, you are relaxed. This reduces your blood pressure! 

3.    Smiling Makes You Look Younger
For those who are worried about growing old, smiling is the best medicine. The muscles we use to smile also lift the face, making a person appear younger.

4.    Smiling Makes You Seem Successful
Studies have shown that people who smile regularly appear more confident, are more likely to be promoted, and are more likely to be approached.

5.    Smiling enhances one’s 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.

6.    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.

7.    Smiling can be contagious 
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!"

The above facts were complied from

With so many benefits, smiling is indeed the best option. It certainly costs you nothing, but can be a boon to you in dealing with your problems.
