A study performed by Dr Dawson Church, PhD and Dr David Feinstein, PhD, measured cortisol levels before and after treatment.
How Did The Study Work?
During this study, 83 participants were divided into 3 groups:
- The 1st group received an hour of Tapping from an EFT tapping practitioner;
- The 2nd group received an hour of psychotherapy (“talk” therapy);
- The 3rd group (control group) received no treatment.
The researchers measured cortisol levels before and after the treatment. Cortisol was measured because it is known as the “stress hormone” of the body. As stress goes up, cortisol levels go up.
What Were The Results of The Study?
When the researchers measured the Tapping group’s cortisol levels after treatment, they thought they had a problem. The levels had dropped so significantly in such a short period that they thought there must be something wrong with their equipment.
They kept recalibrating their equipment and retesting until they finally concluded that there was, in fact, nothing wrong with their equipment but rather that the Tapping worked!
Stress test results: The 1st group (Tapping) demonstrated a 24% decrease in cortisol levels; the 2nd and 3rd groups showed the regular decrease in cortisol levels that happens over time.
The reality: Psychotherapy alone relieves stress, but over a long period. The immediate benefits of psychotherapy don’t register in your body, where excessive amounts of the “stress hormone” cortisol still run rampant, putting your health at risk.
Study findings: Tapping EFT balances activity between the sympathetic and parasympathetic regions of your brain, producing “a neutral emotional state,” the gold standard of health and wellness.
