EFT stands for Emotional Freedom Techniques.
How EFT works: you are "Tapping" on 9 specific body points, the ends of the Chinese Meridians (as in acupuncture). You are tapping while tuning into your thoughts and feelings: this sends a message to the amygdala (the part of the brain which is responsible for emotions, survival instincts and memory) that all is well, that it is safe to relax…
This process, which is best done with an experienced practitioner, has the effect of disengaging whatever you were tapping on from the body’s stress response and can have immediate emotional and even physical results.
The results of EFT can be the clearing of negative thoughts, beliefs and trauma, which can then give way to re-framing those same thoughts positively without force or effort on your part. This can lead to life changes in ways both big and small.
Dr. David Feinstein, a clinical psychologist who uses Emotional Freedom Technique in his own practice, adds that EFT is “unusually precise, rapid, and direct for shifting the neurological underpinnings of a range of psychological problems.”
Research suggests that EFT may be so effective because of its ability to balance out the central nervous system, leveling off the activity of the parasympathetic and sympathetic regions of the brain.
