EFT has been researched at a physiological level, including its effects on genes. An initial pilot study compared an hour-long EFT session with a placebo session (where subjects thought they were getting a treatment, but it did not have an active component) in four participants. What this small study found was incredible.

After the single EFT session, differential expression in 72 genes associated with the suppression of cancer tumors, protection against ultraviolet radiation, regulation of type 2 diabetes insulin resistance, immunity from opportunistic infections, antiviral activity, synaptic connectivity between neurons, synthesis of both red and white blood cells, enhancement of male fertility, building white matter in the brain, metabolic regulation, neural plasticity, reinforcement of cell membranes, and the reduction of oxidative stress occurred. This was a profound outcome and the first of its kind in this field.

There has since been another study that examined the regulation of six genes associated with inflammation and immunity after EFT treatment. In a study of 16 war veterans with PTSD who received 10 hour-long EFT sessions, interleukins, which are responsible for the regulating our body’s inflammation response, decreased significantly in expression. And “good” genes associated with improved functioning of the immune system were up-regulated (expressed). There was also a significant association between improvement in the veterans’ mental-health symptoms and positive changes in the expression of their genes related to stress hormones.

Now isn’t that a good reason to start tapping today?
