When we laugh, Endorphins are released, various muscle groups become active and the heart is stimulated by the diaphragm. After a good laugh, our blood pressure drops and our muscles relax.
Thus, laughter is not only good for the mind, but also good for the heart! 
So let's spend today’s World Happiness Day laughing wholeheartedly and making our loved ones laugh :)
