People love to laugh. We love it so much when there are jokes, jobs, and shows that are made to make us laugh. Even though laughing seems natural, not many species are able to do so.

Laughing involves the performance of rhythmic, involuntary movements, and the production of sounds. We are able to laugh using fifteen facial muscles, our respiratory system, and sometimes even our tear ducts. We are lucky that we are able to laugh because there is strong evidence that laughter can help improve health. Laughter boosts the immune system and adds another layer of protection from disease. Since laughter also increases blood flow, it improves the function of blood vessels that helps protect the heart. Laughter also relaxes the whole body by relieving tension and stress. Finally, laughter also brings out the body’s natural feel-good chemicals that promote well-being.
