The same research team at Loma Linda, California, conducted a similar study recently to see if the anticipation of laughter that was shown to boost immune systems could also reduce the levels of three stress hormones: cortisol ( "the stress hormone"), epinephrine (adrenaline), and dopac, a dopamine catabolite (brain chemical which helps produce epinephrine).

On the physical level, laughter relaxes our muscles, reduces at least four hormones associated with the stress response, epinephrine, cortisol, dopac, and growth hormone, strengthens our immune system, is great cardiac conditioning like "inner jogging" and lowers blood pressure.

Specifically, Dr. Berk reported that the anticipation of a happy laughter experience lowers three stress hormones: cortisol (a steroid hormone), epinephrine (also known as adrenaline), and dopac (a major catabolite of dopamine).

Using a similar protocol as in the earlier study, the current research found that the same anticipation of laughter reduced cortisol by 39 percent, epinephrine by 70 percent, and dopac by 38 percent.

Analysis showed that the blood levels in the anticipatory phase decreased for the stress hormones cortisol, epinephrine, and dopac in the experimental group.

The experimental group showed a decrease in stress hormones (cortisol, epinephrine, dopac - measures dopamine levels), but also increases in beta-endorphins (chemicals that reduce depression) and human growth hormone

Cortisol (termed "the steroid stress hormone"), epinephrine (also known as adrenaline) and dopac, (the major catabolite of dopamine), were reduced 39, 70 and 38\%, respectively (statistically significant compared to the control group).
