Laughing Matters | Comedy Documentary

Laughter is a pleasant physical reaction consisting usually of rhythmical, often audible contractions of the diaphragm and other parts of the respiratory system. It is a response to certain external or internal stimuli. Laughter can arise from such activities as being tickled, or from humorous stories or thoughts.
Laughter enhances your intake of oxygen-rich air, stimulates your heart, lungs and muscles, and increases the endorphins that are released by your brain. Activate and relieve your stress response.
Some types of laughter include the belly laugh, chortle, cachinnation, chuckle, bray and giggle.
Laughter will help improve your metabolism naturally, which in turn, influences your body to burn more calories and lose weight. Researchers have determined that just 15 minutes of laughter a day can help you burn between 10 and 40 calories, depending on your weight and how intense your laughter is.
