Many studies have looked at the benefits laughter brings to the body. When we laugh, it triggers the part of the brain known as the nucleus accumbens, which in turn releases the chemical dopamine. When dopamine is released, mood is increased. Furthermore, laughter helps release muscle tension in our bodies helping us to relax. It affects the diaphragm, abdominal muscles and shoulders.
Laughter is good for the heart, which is also a muscle. Research found that watching a funny movie improves blood-vessel function. Such change helps reduce the risk of cardiovascular disease. It can also help lower blood pressure. In addition it can bring a boost to the immune system, therefore helping to keep illness at bay. When we laugh there is increased production of immune cells and gamma interferon which serve to raise immunity.
