EFT stands for Emotional Freedom Techniques. It is also known as Tapping because it involves using your fingertips to tap on acupressure points on your body.
Fascinatingly, research shows this simple, gentle action is powerful enough to rewire your brain!
When you think about something that bothers you, your brain stresses and your body feels it. Research shows tapping on specific points of your body sends calming signals to the brain. When you think about something that bothers you as you tap on these points, you rewire your brain for calmness. You essentially tell your brain and body that "this is not an issue; there's no need to stress", in a language that your brain and body understand.
This method has deep roots in the field of psychology. It has long been known (since the 1800s) that there are links between our psychology and physiology - meaning your mind and body are connected. EFT is a mind-body approach to decreasing stress.
