Expecting fun is almost as good as having fun.
In a paper being presented in an American Physiological Society session at Experimental Biology 2006, Lee S. Berk of Loma Linda University, reports that . . . just the anticipation of the "mirthful laughter" involved in watching your favorite funny movie has some very surprising and significant neuroendocrine/hormone effects.
According to Berk: "The blood drawn from experimental subjects just before they watched the video had 27% more beta-endorphins and 87% more human growth hormone, compared to blood from the control group, which didn't anticipate the watching of a humorous video. . .
"Mirthful laughter diminishes the secretion of cortisol and epinephrine, while enhancing immune reactivity. In addition, mirthful laughter boosts secretion of growth hormone, an enhancer of these same key immune responses. The physiological effects of a single one-hour session viewing a humorous video has appeared to last up to 12 to 24 hours in some individuals," Berk noted, " while other studies of daily 30-minute exposure produces profound and long-lasting changes in these measures.
Though video watching doesn't appeal to everyone the effect may be more general. Anticipating having a fun time of any sort is likely good for you.
