The author reports that while laughing can increase immunity, new research demonstrates that even anticipating laughs can boost immunity. In volunteers who had blood drawn, prior to, during, and after watching funny movies, blood from movie watchers before the show had 27% more endorphins and 87% more human growth hormone than a control group. Elevated endorphins and human growth hormone enhance immunity and reduce stress.
