It has been proven scientifically for almost 50 years that laughter can help boost the body’s immune system, prevent cancer and help heal diseases of all kinds.

The Science of Laughter

First reported by a group of scientists lead by Ronald E. Smith from the University of Washington in 1971, laughter can significantly reduce levels of stress hormones in the body.[1][2][3]

By reducing blood concentrations of stress hormones[4] cortisol, adrenaline and others, the body’s immune system is strengthened[5] and becomes better able to fight off infections and every known disease and health condition, including cancer.[6][7][8][9][10][11][12][13]

Simply Anticipating Something Funny Lowers Stress

Remarkably, just by visiting this web page, your anticipation of encountering something funny has ALREADY lowered your stress hormone levels, according to a group of scientists from Loma Linda University, California in a study from 2008.[14]  In this study, the anticipation of laughter reduced stress hormones cortisol, epinephrine and dopac by 39 percent, 70 percent and 38 percent, respectively.
