It may be hard to believe, but laughter actually effects our body's capacity to create immunity to different diseases, according to a study by the University of California, Loma Linda. It was shown that the effects of laughter decrease the level of cortisol, which suppresses the immune system. Those effects also raise the activity of the cells that combat and destroy abnormal cells and double the level of plasma that strengthens the immune system.
