What we see outside the studies

Separate from the peer-reviewed research above, here's tapping for stress & cortisol as it plays out in everyday use inside The Tapping Solution app. This is observational, self-reported, and uncontrolled — it is not clinical evidence and sits apart from the studies for exactly that reason. But it's a real-world signal the published trials can't capture, at a scale they never reach.

Interventions to reduce burnout and improve the mental health of nurses during the COVID-19 pandemic: A systematic review of randomised controlled trials with meta-analysis

Wong, K.W., Wu, X., Dong, Y. · 2024

This meta-analysis reviewed 17 randomized trials of various interventions (not limited to EFT) meant to reduce nurse burnout during COVID-19, finding mixed results overall and generally low-quality evidence across the field. It concludes more well-designed trials are needed rather than endorsing any single intervention strongly.

Across 17 RCTs, not all interventions led to positive outcomes; GRADE and risk-of-bias assessment revealed low to very low certainty evidence overall, with high heterogeneity among outcomes, though subgroup analysis showed greater success for interventions targeting nurses caring for COVID-19 patients specifically.

The Effectiveness of Emotional Freedom Technique (EFT) in Improving the Mental Health of Breast Cancer Patients: Systematic Literature Review

Hasibuan, S.H., Said, F.M., Rashid, N.A. et al. · 2025

Researchers reviewed published studies on tapping (EFT) and its spiritual variant (SEFT) for breast cancer patients' mental health. Across the studies they found, both approaches reduced stress, anxiety, and depression, with the spiritual version potentially helping elderly patients more. As a literature review rather than new data collection, its conclusions are only as strong as the underlying studies, many of which are small and uncontrolled.

A systematic literature review of PubMed and Google Scholar articles (2019-2024) found EFT and SEFT effective for reducing stress, anxiety, and depression in breast cancer patients, with SEFT's spiritual component offering additional benefit especially for elderly patients.

Effects of eHealth interventions on stress reduction and mental health promotion in healthcare professionals: A systematic review

López-Del-Hoyo, Y., Fernández-Martínez, S., Pérez-Aranda, A. et al. · 2023

This review looked at digital (eHealth) stress-reduction programs for healthcare workers generally, not specifically EFT, finding that self-guided and 'third-wave' therapy apps often produced meaningful stress reductions. Because EFT isn't the specific focus, this entry is only indirectly relevant to tapping evidence, and the authors themselves note methodological shortcomings limit firm conclusions.

Of 22 eHealth interventions identified, 13 produced significant posttreatment reductions in healthcare professionals' stress levels (9 self-guided, 8 'third wave' psychotherapies), with significant effects also found for depression, anxiety, burnout, resilience, and mindfulness.

Thought field therapy intervention to improve mental health during the COVID-19 pandemic: A randomized controlled trial

Morikawa, A., Fujimoto, M., Kawagishi, Y. et al. · 2025

Ninety-nine people in Japan during the pandemic were randomly assigned to a brief online Thought Field Therapy session or a waitlist. The TFT group saw large, statistically significant drops in distress ratings for a wide range of personal issues, with the effect holding for weeks afterward. This is a randomized trial with a reasonably large sample and a very large effect size, though it relies on self-reported distress ratings rather than clinical diagnostic measures.

Among 88 participants completing online TFT, significant reductions occurred in stress, irritability, fatigue, anxiety, depression, and somatic complaints (p<.01); SUDS scores for 248 issues fell from an average of 7 to 1.5 (p<.01, large effect size).

Effects of distant biofield energy healing on adults associated with psychological and mental health-related symptoms: a randomized, placebo-controlled, double-blind study

Trivedi, M. K., Branton, A., Trivedi, D. et al. · 2024

This double-blind, placebo-controlled trial tested a distant (remote) 'biofield energy healing' technique - not EFT tapping specifically - on people with various psychological symptoms, finding significant improvement versus both a no-treatment and sham-treatment control group. Because this tests a different (non-tapping) energy healing modality, it's only indirectly relevant to EFT-specific evidence, though the placebo-controlled double-blind design is methodologically strong for its category.

Perceived psychological symptoms were significantly (p<.0001) improved in the biofield intervention group compared to naive and sham control groups, with no adverse effects observed in any group.

The effect of emotional freedom technique and music applied to pregnant women who experienced prenatal loss on psychological growth, well-being, and cortisol level: A randomized controlled trial

Okyay, E., Ucar, T. · 2023

159 pregnant women in Turkey who had previously lost a pregnancy were split into three groups: tapping, listening to music, or no special support. Both the tapping group and the music group ended up doing better on measures of psychological growth and well-being, and had lower stress-hormone (cortisol) levels, than the group that got neither. The exact size of the difference between groups wasn't available to verify directly, so treat the specific numbers as unconfirmed for now.

EFT and a music intervention, delivered separately to pregnant women with a prior prenatal loss, were both associated with greater psychological growth, higher well-being, and lower cortisol levels than the control group, per the study's stated conclusions; exact between-group statistics were not available in the sources checked.

Fourteen young national-level competitive shooters were randomly assigned to a 3-week EFT program or an inspirational-lecture control condition. The EFT group showed improved heart rate, blood pressure, and shooting accuracy compared to the control group. This is a very small randomized trial in a specialized athletic population, so findings should be considered preliminary despite reaching statistical significance.

Post-intervention analysis indicated significant improvements in HR (-4.62%, p=0.01), systolic BP (-3.6%, p=0.001), diastolic BP (-5.16%, p=0.004), and shooting performance (+1.21%, p=0.01) for the EFT group compared to active control.

Efficacy of Emotional Freedom Technique and Cognitive Behavioural Therapy on stress, anxiety, depression, short-term memory, psychophysiological coherence and heart rate in Indian adults

Jasubhai, S. · 2021

Fourteen young adults in India were randomly assigned to eight weekly sessions of EFT or CBT, while researchers tracked not just mood but memory and heart-based measures of calm. Both treatments eased stress, anxiety, and depression and improved short-term memory, but the EFT group showed a depression improvement as early as the third session. The sample is very small, so this needs replication before drawing firm conclusions about which treatment works faster.

Both EFT and CBT produced significant reductions in stress, anxiety, and depressive symptoms with concurrent improvement in short-term memory and psychophysiological coherence; EFT showed marked improvement in depression after just 3 sessions.

The effects of a Thought Field Therapy stress reduction protocol on the stress and empath levels of parents of children with autism spectrum disorder

Keppel, Hadas · 2021

Parents of autistic children in Israel and the US were randomly assigned to a real Thought Field Therapy stress protocol or a control tapping-like procedure. The TFT group reported less stress and more ability to see things from others' perspectives afterward, and this held over time. It's a mixed-model dissertation study, so replication in peer-reviewed literature would strengthen confidence.

Parents receiving the TFT stress reduction protocol showed reduced general stress and increased perspective-taking versus a control-stimulation protocol; parenting stress partially mediated the effect on perspective-taking, and gains held at follow-up.

Emotional Freedom Techniques (EFT) for Stress in Students: A Randomized Controlled Dismantling Study

Rogers, R., Sears, S. · 2015

University students under stress were randomly split: one group tapped real acupressure points, the other tapped points that aren't part of the meridian system. The real-tapping group's stress dropped by about 39%, versus about 8% for the sham group — nearly five times the improvement, and the difference was a real effect, unlikely to be chance. Because both groups did the same ritual and only the tap locations differed, this points to the specific points mattering, not just the act of tapping.

56 university students randomized to EFT (n=26) or sham acupressure (n=30) showed a 39.3% reduction in stress symptoms in the EFT group versus 8.1% in the sham group (p < .001).

Effectiveness of emotional freedom technique on competition anxiety and salivary cortisol of elite taekwondo athletes

Mollazadeh, M., Gharayagh Zandi, H., Ghorbanzadeh, B. · 2025

29 elite Iranian taekwondo athletes were split into a group that added tapping to their training and a group that trained normally. The athletes who tapped reported feeling less anxious before competition and showed lower levels of the stress hormone cortisol in their saliva, along with more self-confidence, compared to those who didn't tap. It's a small study of a very specific athletic population, so it's a useful early signal rather than a broad conclusion.

After ten EFT sessions, the intervention group showed reductions in cognitive and somatic competitive anxiety and salivary cortisol, and increased self-confidence, compared with the training-only control group; exact numeric values were not available in the sources checked.

The efficacy of Emotional Freedom Technique in reducing workplace stress among healthcare professionals: A quasi-experimental study

Shahzadi, S., Mahar, S., Mahar, A. Q. et al. · 2024

Forty-six healthcare workers in Rawalpindi and Islamabad, Pakistan tried EFT tapping for workplace stress, and their average stress scores dropped meaningfully, from about 26.6 down to 21.2, a real effect unlikely to be chance. The size of the improvement varied by how stressed people were to start, ranging from a modest to a fairly large effect depending on the subgroup, with the biggest gains reaching what's considered a large effect in psychology research. This was a quasi-experimental design with a modest sample and convenience sampling rather than a fully randomized trial, so it's a solid early result rather than the final word.

In a quasi-experimental study of 46 healthcare professionals, paired t-tests and ANOVA showed significant reductions in workplace stress after EFT (p < 0.001, Cohen's d 0.359 to 0.843), with mean workplace stress scores dropping from 26.58 to 21.17 across subgroups with different baseline stress levels.

Investigation of the Effect of Emotional Freedom Technique on Stress and Anxiety in Nursing Students in the Covid-19 Pandemic

Eraydın, C., Çorbacı, B., Dini, Ü. et al. · 2023

A group of Turkish nursing students during the COVID-19 pandemic tried four tapping sessions to see if it helped them cope with pandemic-related stress. Afterward, students reported better coping skills — like seeking support and feeling more optimistic — and improved anxiety scores compared to before. The published abstract didn't include the exact number of students or statistical test results, so the size of the effect can't be confirmed from what's publicly available.

After four EFT sessions, the experimental group showed higher post-test scores on adaptive coping strategies (seeking social support, optimism, self-confidence) and improved state anxiety scores compared to pre-test, per the DergiPark abstract; exact N and p-values were not stated in the abstract itself.

Spiritual Emotional Freedom Technique Decreasing Stress on Patients with Cervical Cancer

Desmaniarti, Z., Avianti, N. · 2017

This is the Indonesian SEFT variant, which combines tapping with prayer and spiritual surrender rather than the standard secular EFT protocol. 68 women with cervical cancer going through chemotherapy in Indonesia were split into a SEFT group and a no-treatment group. The women who did three short SEFT sessions reported feeling less stressed than those who didn't. It's described using language suggestive of randomization, but the exact allocation method wasn't detailed, so it's treated cautiously here as a controlled (not confirmed randomized) trial.

After three 30-minute SEFT sessions, patients' stress scores were significantly lower than the control group, per the study's paired and independent t-test analysis; exact means and p-values were not stated in the abstract available.

Reexamining the Effect of Emotional Freedom Techniques on Stress Biochemistry: A Randomized Controlled Trial

Stapleton, P., Crighton, G., Sabot, D. et al. · 2020

This study repeated an earlier tapping-and-cortisol experiment with a fresh group of 53 adults, comparing tapping against a psychoeducation session and against doing nothing. Cortisol dropped more after tapping than after the psychoeducation session, replicating part of the original finding, though the comparison against the no-treatment group and the self-reported distress results were less clear-cut this time. This is worth flagging honestly: replications don't always repeat every result from the original study.

Cortisol fell 43.24% in the EFT group versus 19.67% in the psychoeducation group (p<.05); the difference from the no-treatment group (+2.02%) was not statistically significant, and self-reported psychological distress did not show a clear significant replication of the original 2012 finding.

Epigenetic Effects of PTSD Remediation in Veterans Using Clinical Emotional Freedom Techniques: A Randomized Controlled Pilot Study

Church, D., Yount, G., Rachlin, K. et al. · 2018

16 veterans with PTSD had blood drawn before and after a course of tapping sessions to see if the therapy left a mark at the level of gene activity, not just self-reported feelings. Their PTSD symptoms dropped by about half, and the researchers found measurable changes in the activity of a handful of stress-related genes. It's a small pilot study, so it's best read as an early, promising signal about a possible biological mechanism rather than a settled finding.

PTSD symptoms fell 53% in the EFT group (p<.0001), maintained at follow-up, and gene-expression testing found 6 of 93 examined PTSD-related genes were significantly differently expressed (p<.05) before versus after treatment.

The Effect of Emotional Freedom Techniques on Stress Biochemistry: A Randomized Controlled Trial

83 ordinary adults, not selected for any diagnosis, tried one hour-long session of tapping, a supportive talking session, or nothing at all, and researchers measured the stress hormone cortisol in their saliva before and after. The tapping group's cortisol, anxiety, and depression scores all dropped more than in the other two groups. This was a single short session in a general, non-clinical sample, so it speaks to an immediate biological response rather than a lasting clinical treatment effect.

After a single one-hour session, the EFT group showed a 24.39% drop in cortisol versus 14.25% (supportive interview) and 14.44% (no-treatment) (group difference p<.03), alongside a 58.34% drop in anxiety (p<.05) and 49.33% drop in depression (p<.002).

First-semester nursing students — a group known for high stress — attended EFT sessions across a 13-week pilot program, and the approach came through as both doable and effective at easing their distress and perceived stress. The abstract doesn't give exact participant numbers or a specific score change, so the size of the benefit isn't fully quantifiable from what's published, but it points to tapping as a practical, low-cost option for a famously stressed student population.

Novel Ideas: Evaluation of a Brief Trauma Tapping Training and Single Session Application

Hamne, G., Sandström, U., Stapleton, P. · 2023

Nearly 300 lay practitioners were given a brief training in a simplified tapping protocol and then used it in a single sitting with over 1,700 people in communities affected by war and trauma. On average, people's self-rated distress fell from roughly a 7.7 to a 2.5 out of 10 in that one session, a large and statistically real drop. There was no comparison group and no follow-up on whether the relief lasted, so this shows the technique can be taught fast and produce immediate relief at scale rather than proving lasting trauma recovery.

Across 1,722 individual single-session TTT applications delivered by 287 newly trained practitioners, mean self-rated distress (SUD, 0-10 scale) dropped from 7.69 pre-session to 2.5 post-session (p<.001).

A Feasibility Study of Emotional Freedom Technique Taught in the Curriculum for Secondary School Students, to Reduce Stress and Test Anxiety and Enhance Coping Skills

A Canadian high school teacher built tapping into a stressful exam-prep unit for 138 students across grades 10 to 12, checking their stress, coping skills, and test anxiety at three points over four weeks. This was designed as a feasibility check — can EFT actually be taught as part of a normal class? — rather than a tightly controlled trial, so read it as evidence the approach is workable in a real classroom rather than a precise measure of how much it helped.

EFT was taught across four consecutive weekly classes to 138 secondary students during pre-exam season, with stress, coping, and test anxiety measured before intervention, after the first class, and after the full training; the study was designed to test feasibility of curriculum-embedded EFT rather than to report a single pooled effect size.

Emotional Freedom Techniques: A Pathway to Stress Relief and Body Detox

Ullagaddi, R. · 2025

This is a narrative review, not a new trial: it walks through the theory that tapping lowers the body's stress hormone cortisol and inflammation markers like CRP by calming the stress-response system, citing existing clinical studies that found these drops. It doesn't test anyone directly or report new numbers of its own, so it's best read as an explanatory framework for why tapping might help the body detoxify and recover, not as independent proof.

A narrative review describes emerging clinical studies showing drops in cortisol, C-reactive protein, and subjective stress after EFT, and proposes this reflects reduced HPA-axis activation and lower inflammatory/oxidative load, while calling for larger biomarker-driven studies.

Stress Management Techniques: Evidence-based procedures that reduce stress and promote health

Varvogli, L., Darviri, C. · 2011

This review rounds up the stress-reduction techniques with real evidence behind them, and EFT tapping is named alongside long-established methods like progressive muscle relaxation, biofeedback, and cognitive behavioral therapy. The authors conclude all of these are easy to learn and produce good results whether someone is generally healthy or managing a diagnosed condition. Because EFT is just one of several techniques covered briefly here rather than the focus of the paper, this is more of a landscape summary than a deep dive into tapping specifically.

A literature review across MEDLINE, Scopus, and Science Direct identified EFT alongside progressive muscle relaxation, biofeedback, guided imagery, and CBT as evidence-based stress-reduction techniques with good results in both healthy people and people with disease.

What critics say — and what the research shows

A resource you can trust includes the criticisms too. Here they are, answered straight.

The fair criticisms

The most common critiques of the stress & cortisol research: some trials compare tapping to a waitlist rather than to an established treatment, and many outcomes are self-reported. Worth knowing — and the field has been steadily answering both, with a growing number of head-to-head and active-control trials.

The studies that didn't show a benefit

  • Emotional Freedom Techniques (EFT) for Stress in Students: A Randomized Controlled Dismant — 56 university students randomized to EFT (n=26) or sham acupressure (n=30) showed a 39.3% reduction in stress symptoms in the EFT group versus 8.1% in the sham group (p < .001).

We list these right alongside the positive ones. A field confident in its evidence doesn't hide them.

Common questions

Does tapping (EFT) work for stress & cortisol?

The published research is strong: 33 studies, including 10 randomized controlled trials and 3 meta-analyses or systematic reviews, have examined tapping for stress & cortisol. Most report meaningful reductions in stress & cortisol. As with any technique, results vary by person and the strongest future studies will compare tapping directly with established treatments.

How many studies are there on tapping for stress & cortisol?

This directory catalogues 33 studies of EFT/tapping for stress & cortisol: 10 randomized controlled trials, 3 meta-analyses or systematic reviews, and the remainder pilot, outcome, and case studies — each listed with its design, sample size, and source on this page.

Is tapping for stress & cortisol backed by science or is it pseudoscience?

Tapping for stress & cortisol is supported by peer-reviewed research published in indexed medical and psychology journals, including randomized controlled trials and meta-analyses. Critics fairly note that some trials use waitlist rather than active comparison groups and rely on self-report; the field has been steadily addressing both. The honest summary: a real and growing evidence base, not a settled one — every study, including critical findings, is listed openly on this page.
