Tapping Reduces Cortisol by 43%
That is what Dr. Peta Stapleton on Bond University in Australia found when she replicated Dawson Church’s 2012 cortisol study. In the original study, Church et al examined salivary cortisol levels in 83 subjects who were randomly assigned to either an emotional freedom technique (EFT) group, a psychotherapy group (SL for Sympathetic Listening) or a no treatment group (NT). The EFT group had a 50-minute session of tapping with a certified EFT coach. The NT group waited 50 minutes in the waiting room and the SL group had a 50-minute session with a licensed therapist. Cortisol was assayed just before and 30 minutes after an intervention. Emotional distress was assessed using the Symptom Assessment-45 to measure the subject’s level of anxiety and depression. The EFT group measured a significant decrease (p<0.03) in mean cortisol level (-24.39%) compared to a decrease of -14.25% in the SI group and -14.44% in the NT group.
Dr. Stapleton replicated the original Church study almost exactly. However, her results were even more dramatic. The EFT group reduced cortisol after 1 hour of EFT by 43%. There were 53 subjects in this study randomly assigned to one of the three groups. The Symptom Assessment-45 was again used to assess psychological distress. Salivary cortisol assessment was performed 30 minutes before the intervention and 30 minutes after.
Cortisol is considered to be an important biological marker of stress. EFT or acupoint stimulation is shown to be an effective method to reduce stress-related cortisol in a person. In an experimental situation, this is “interesting” and often that is all that happens with a reader who has an interest in stress reduction. In a real life situation, however, where someone has a history of not dealing well with stress, finding a short, easy to apply method that reliably reduces the amount of cortisol circulating in their body, the importance cannot be over-stated.
Creating a list of people who have a history of “not dealing well with stress” is an important first step. These are people who for some reason tend to hold the stress producing situation in their minds and continue to think about it, such as people who are more likely to have anxiety disorders like GAD or PTSD. The list should also include people who because of their physical condition, such as being pregnant, do not want to maintain high levels of cortisol in their blood.
An important second step as clinicians is for us to introduce them to various techniques to help them reduce their stress related cortisol. The Tapping Solution is possibly NOT the best technique. That remains to be seen. However, it is surely experimentally proven to reliably reduce cortisol and it is easy to do.
It might make a good tool for your therapy box if you see and treat people with anxiety.
