The Science Behind EFT Tapping
There are more than 300 published studies of tapping, including nearly 100 randomized controlled trials. We’ll be honest with you about the science — which means we’ll tell you what’s strong, what’s still debated, and where reasonable people disagree. We don’t believe overclaiming serves you or honors God. What we do believe is that the evidence for EFT’s effects is substantial, independently replicated, and growing — and that you deserve to know what’s actually in the research before you decide what to make of it.
What the research shows: the numbers and their sources
One hour of tapping cut cortisol, the body's main stress hormone, by 43%, more than double the drop from an hour of talk-based education.

A 2016 review of 14 randomized trials (Clond) found that tapping significantly reduced anxiety.

In a randomized trial with veterans, 90% no longer met the clinical criteria for PTSD after six coached tapping sessions alongside their regular care, compared with 4% of those on a waiting list who continued their regular care. Among everyone who went through the tapping sessions, 86% were still free of PTSD criteria three months later, and 80% at six months.
Church et al., J. Nervous & Mental Disease, 2013
A review of 7 randomized trials (Sebastian & Nelms, 2017) found a large effect on PTSD in 4 to 10 sessions, compared with usual care or a waiting list, and a 2025 review of 13 studies (Chen et al.) found the gains still held three months later.

A review of 20 studies (Nelms & Castel, 2016) found that tapping had a large effect on depression in randomized trials.

In a 2022 study of adults with chronic pain (Stapleton et al.), six weeks of online group tapping lowered pain by 21% and anxiety by 37%.

Tapping in Faith is a practice alongside faith and good care, not a replacement for either. If you’re living with trauma or a health condition, keep working with your doctor or counselor.
What’s actually happening in the body
EFT works through at least four mechanisms, each with independent support:
Cognitive exposure
Naming and voicing a distressing thought or emotion — which is what the setup statement does — is the active ingredient in CBT and prolonged exposure therapy. You're not suppressing the fear. You're bringing it into the light and holding it there while something else happens simultaneously.
Amygdala down-regulation via acupoint stimulation
Early brain-scan research used MRI to watch tapping change activity in the brain's craving and emotion centers. Tapping sends calming input through the trigeminal and vagus nerves while the distressing thought is held in mind, interrupting the conditioned fear response at the source.
HPA-axis and parasympathetic regulation
The cortisol studies measure this directly. EFT activates the parasympathetic nervous system (rest-and-digest) and suppresses the hypothalamic-pituitary-adrenal axis. This is measurable, biological, and reproducible.
Memory reconsolidation
Recent neuroscience suggests that simultaneously activating an emotional memory while delivering contradictory somatic input — calm touch, slow breath, spoken truth — creates the conditions the brain requires to update a fear learning rather than merely suppress it. The memory doesn't disappear. It loses its threat charge.
The original theory behind EFT involved Chinese medicine’s concept of chi flowing through energy meridians. We don’t use this framing — it’s not scientifically validated, and it carries theological baggage that unnecessarily concerns Christian users. The neurological mechanism above is sufficient, better evidenced, and more consistent with a Christian understanding of embodied human nature.
How the clinical world sees EFT
The U.S. Department of Veterans Affairs listed EFT among therapies considered generally safe for use with veterans in 2017. The UK’s NICE guidelines (NG116, 2018) referenced EFT for PTSD for the first time. The Faculty of Medicine at the University of Lyon-Est (France) includes EFT in its Brief Therapies curriculum.
EFT is not currently listed by APA’s Division 12 as an empirically supported treatment. In 2023, the Society of Clinical Psychology excluded EFT during an evaluation process — not for lack of evidence, but because new criteria required a treatment’s theoretical mechanism to be based on established psychological science. Because EFT’s original mechanism (energy meridians) does not meet that standard, it was excluded on definitional grounds rather than empirical ones. The evidence for the effects is strong and independent. The evidence for the original theory is not.
EFT is roughly where EMDR was fifteen years ago: substantial empirical support, growing clinical use, contested theoretical framework, and a trail of peer-reviewed studies that keeps getting longer. EMDR is now a front-line PTSD treatment. The trajectory of EFT is similar.
We believe the effects are real, and the studies are independent. Reviews that pool many trials have found tapping’s effects to be moderate to large, including for anxiety and depression. We don’t require you to accept any particular theory about why it works.
What tapping is — and isn’t
Tapping in Faith is a guided audio app, not a clinical service. EFT is a complement to professional care, not a replacement. If you are experiencing severe PTSD, major depressive disorder, suicidal thoughts, active psychosis, or other serious mental health conditions, please work with a licensed therapist.
