Cheerful Expression, Brighter Life People with cheerful faces are like broadcasting positive signals to everyone around them. They come across as friendly, helpful, caring, and trustworthy. That's why it's no surprise that people who are consistently cheerful tend to be happier, have longer-lasting marriages, and even live longer than those who rarely smile.
As an illustration:
Ever had a moment when you're in a bad mood, and then a friend shows up with positive energy and a big smile, and suddenly your mood lifts? That's because smiles are contagious. So if you want to brighten someone's day, just start with a smile :)
That's why in Islam, smiling is even considered charity. Because when you smile, you're already doing good and spreading positive energy to others.
