It is similar to using a VCR remote control or tapping a key on a keyboard to send an electrical signal to the computer. This keeps their attention on the disturbance. The tapping removes or reduces the distress and the problem is alleviated. Acupressure has been practiced for over 5000 years in the Orient, however its successful application to correcting problematic affective states is relatively new. Through EFT, stimulation of these meridians brings about psychological and physical change.
Energy meridians are in fact measurable fields that surround and permeate our bodies.
Our mental and physical states are influenced by our subtle but detectable electromagnetic fields. A common example of this can be found in our reaction to pain. For example, a woman in labor sometimes is tuned into the pain and, at other times, is distracted from it. Her pain is not likely to be constant. Later, the pain reasserts itself in her awareness and she hurts again.
