Laughter diminishes the secretion of cortisol and epinephrine, while enhancing immune reactivity. In addition, laughter boosts secretion of growth hormone, an enhancer of these same key immune responses. The physiological effects of a single 1-hour session viewing a humorous video has appeared to last up to 12-24 hours in some individuals. (Expectation of Laughter Boosts Endorphins 27% and Human Growth Hormone 87%.)
Studies: Two hormones, beta-endorphins (the family of chemicals that elevates mood state) and human growth hormone (HGH, which helps with optimizing immunity), increased by 27% and 87% respectively in study subjects who anticipated watching a humorous video. There was no such increase among the control group who did not anticipate watching the humorous film. The physiological effects of a single 1-hour session viewing a humorous video has appeared to last up to 12-24 hours in some individuals."
Laughter increased two hormones:
- Human growth hormone (HGS): which helps with immunity.
- Beta-endorphins: the family of chemicals that alleviates depression.
Studies by Dr. Berk of Loma Linda University: Beta-Endorphin and Human Growth Hormone increase are associated with both the anticipation and experience of mirthful laughter. (Berk, Lee S. PhD. Paper presented in an American Physiological Society session at Experimental Biology, 2006.
Laughter is great medicine, and it's fantastic for generating HGH. ((Human Growth Hormone) and Anti-aging Products Scams Exposed.)
