Laugh & the world laughs with you!
Science from the Mayo Clinic writes that laughter stimulates many organs in your body. For example, laughter enhances the intake of the oxygen-rich air. In addition, it boosts your heart, lungs, and muscles and increases the endorphins that your brain releases.
A chuckle improves mood & creates a happy feeling. It also lowers blood pressure & improves vascular circulation, and has positive effects on your mental health & immune system.
