A landmark study published in 2012 in the prestigious Journal of Nervous and Mental Disease, found that EFT Tapping lowered cortisol significantly more than traditional talk therapy or resting.
In this study, participants were split into three groups and cortisol, often know as the stress hormone, was measured.
After treatment, the control group, which had been reading magazines, showed an increase in 2% in cortisol. The 2nd group, the psychoeducation group, cortisol decreased by 19% after 1 hour of treatment. In the 3rd group, the Tapping group, cortisol decreased by 43% after 1 hour of treatment! More than twice the speed of the 2nd group!
