Meta-analysis Moderate rigor
Kim, J.H., Oh, P.J. · 2016
This meta-analysis pooled 16 clinical trials covering 962 older adults (55+) and looked at non-drug treatments for insomnia — cognitive behavioral therapy, acupuncture, aromatherapy, and emotional freedom techniques among them. Combined, these approaches produced moderate-to-large improvements in sleep quality, sleep efficiency, and how long it took people to fall asleep, though total sleep time and overall insomnia severity didn't move significantly. Because EFT was just one of several therapies pooled together, this tells us non-drug approaches broadly help older adults sleep better, without isolating how much of that credit belongs to tapping alone.
Pooling 16 trials (N=962) of non-pharmacological interventions including EFT, non-pharmacological approaches produced moderate-to-large effects on sleep quality (ES=-1.18), sleep efficiency (ES=-1.14), sleep onset latency (ES=-0.88), awakening time after sleep onset (ES=-0.87), and sleep belief (ES=-0.71), but no significant effect on total sleep time or insomnia severity.

Ninety people in Nanjing, China with COPD (a chronic lung disease) who were also dealing with real anxiety and depression took part in this study. Half got their usual hospital care; half got usual care plus six weeks of tapping sessions. By six weeks, the tapping group had bigger drops in anxiety and depression and did better on sleep, fatigue, and lung-disease-specific quality of life than the group that didn't tap. This is a single-site trial in one hospital, so it's a solid early result rather than a settled answer across all COPD patients.
90 COPD inpatients with anxiety (AIR-C >=8) and depression (SDS >53) were randomized to routine care (n=45) or routine care plus a 6-week EFT program (n=45); the EFT group showed larger declines in anxiety and depression at week 6 and greater improvement in sleep quality, fatigue, and CAT quality-of-life scores than controls.

Qi, W., Xinyi, Y., Yuhan, W. et al. · 2024
Seventy older adults in Nanjing, China living with HIV — many dealing with anxiety, low mood, and poor sleep — were split into two groups. Half added a short daily tapping session to their usual care for two weeks; half continued with usual care alone. The tapping group ended up with better anxiety, mood, and sleep scores than the group that didn't tap. It's a fairly short intervention window (two weeks) in a specific population, so longer-term durability isn't yet established.
70 older adults living with HIV at the Nanjing Public Health Medical Center were randomized to 2 weeks of daily 15-20 minute EFT sessions (n=35) added to routine care, or routine care alone (n=35); the EFT group showed a positive effect on relieving anxiety and depression and improving sleep quality compared to controls.
Randomized trial Moderate rigor
Tang, X., Wang, L., Ni, S. et al. · 2023
Sixty-six people on long-term dialysis for kidney failure — a group that often struggles with poor sleep — were split into a group learning tapping over 12 weeks and a group getting usual care only. The tapping group slept better, felt less anxious and depressed, and had less trouble functioning during the day, and three-quarters said they'd keep using it. This is a pilot study focused partly on whether tapping is even practical for this patient group, and it found that it is, alongside real symptom benefits.
66 hemodialysis patients with sleep problems were randomized to a 12-week EFT intervention or control; the EFT group showed statistically significant improvement in anxiety, depression, sleep quality, sleep duration, and daytime dysfunction versus control, and 75% of participants said they would continue practicing EFT.
Randomized trial Moderate rigor
Özcan, H., Meşedüzü, M., Gülen, E. et al. · 2025
Sixty-four university students with sleep problems were split into a group that got two tapping sessions a month apart and a group that got nothing, and the tapping group came out clearly ahead on insomnia severity, daytime sleepiness, and overall sleep quality. Fatigue scores didn't move any differently between groups, so the benefit showed up in sleep measures specifically, not tiredness. With just two sessions and a no-treatment comparison rather than an active one, it's a clean early signal rather than a head-to-head test against another treatment.
In 64 students randomized to two EFT sessions four weeks apart versus no intervention, the EFT group improved significantly more on Insomnia Severity (t=6.732, p=0.001), Epworth Sleepiness Scale (t=2.16, p=0.034), and Pittsburgh Sleep Quality Index (t=3.934, p=0.001), but not on the Fatigue Severity Scale (t=0.910, p=0.366).
Randomized trial Moderate rigor Critical finding
Souilm, N., et al. · 2022
Sixty older adults with trouble sleeping were split into a group taught tapping for insomnia and a group taught standard sleep hygiene habits (like consistent bedtimes and limiting screens). Both groups slept better afterward, but the sleep-hygiene group actually did slightly better overall, with all of them reaching good sleep quality versus about three in four in the tapping group. This is a straightforward, honest result: tapping helped, but wasn't shown to beat a simple, well-established habit-based approach in this older population.
60 elderly patients were randomized equally to EFT-Insomnia (EFT-I) or sleep hygiene education (SHE); both groups significantly improved sleep quality, but the effect was more pronounced in the SHE group, with all SHE patients regaining good-quality sleep versus about three-quarters of the EFT group.
Randomized trial Moderate rigor
Lee, J.H., Chung, S.Y., Kim, J.W. · 2015
Twenty women in their 80s with insomnia were split into two group-therapy tracks — one learning standard sleep hygiene, the other an insomnia-adapted version of tapping — and the tapping group came out ahead on both insomnia and depression scores. Neither approach moved the needle on anxiety or life satisfaction. With just 20 participants split two ways, this is a small trial best read as an early comparative signal rather than a definitive answer.
In 20 elderly women (mean age 80) randomized to group EFT-I or Sleep Hygiene Education across eight 1-hour sessions, EFT was superior to SHE for insomnia severity and depression, though neither group showed significant improvement in anxiety or life satisfaction.
Controlled trial Moderate rigor
Kalroozi, F., et al. · 2022
Women recovering from breast cancer surgery — some from military families, some not — were taught tapping and compared against similar women who didn't receive it. In both groups, the women who learned tapping slept better and reported more happiness right after and a month later, and it worked equally well regardless of military-family background. This was a quasi-experimental study, meaning participants weren't randomly assigned, so it carries a bit more risk of hidden differences between groups than a full RCT.
Sleep quality and happiness scores improved significantly immediately after and one month after the EFT intervention in both military and nonmilitary intervention groups compared to their respective control groups, with no significant difference between the military and nonmilitary intervention groups.
Controlled trial Moderate rigor
Zheng, D., Xiao, W., Duan, D. et al. · 2025
Fifty-eight people being treated for cancer — many grappling with the fear and sadness of an uncertain future, on top of anxiety and poor sleep — either added four weeks of short guided tapping sessions to their usual care or just continued usual care. The tapping group felt less anticipatory grief, less anxious, and slept better than the comparison group by the end of the month. It's a fairly small trial from a single research group, so a larger follow-up would help confirm the size of the benefit.
58 cancer patients were allocated by ward (not individually randomized, though the paper labels itself an RCT) to 4 weeks of EFT plus routine care (n=30) or routine care alone (n=28); the EFT group had significantly lower anticipatory grief (p<.01), greater anxiety reduction (p=.04), and improved sleep quality (p<.01) after 4 weeks.
Controlled trial Preliminary
Wang, J., Yan, T. L., Zhaoyu, D. · 2024
Thirty people with vague physical and emotional 'sub-health' complaints - the kind of persistent fatigue and unease that doesn't fit a specific diagnosis - tried a four-week EFT program. Their fatigue, anxiety, and depression scores improved significantly compared with a no-intervention group, while sleep quality did not change significantly. This is a small pilot connecting EFT to traditional Chinese medicine's meridian theory, so it should be seen as exploratory.
After a 4-week EFT training regimen, fatigue, anxiety, and depression scores decreased with statistically significant changes compared with a no-intervention group; the sleep-quality change (PSQI) did not reach significance (p>0.05).
Controlled trial Preliminary Critical finding
Ghoreishi, S. S., Pourhadi, S., Hosseini, S. R. et al. · 2023
A group of older adults at a day-care center in Iran tried tapping to see if it would help their sleep, daytime sleepiness, and overall quality of life, compared with a group that didn't tap. Both groups actually improved somewhat over time, but tapping didn't produce an extra benefit beyond what the comparison group experienced. This is a useful reminder that not every EFT study finds a clear advantage, and it's included here for a balanced picture of the evidence.
The study found no significant between-group differences for subjective sleep quality, sleepiness, or quality-of-life subscales, though both groups showed improvement over time — a null result for EFT's added benefit in this population.
Outcome study Moderate rigor Indonesian
Tambunan, M.B., Suwarni, L., Setiawati, L. et al. · 2022
Twenty-two people isolating with confirmed COVID-19 in an Indonesian city took part in a tapping program. Their anxiety, depression, and insomnia scores all dropped by a statistically significant margin from before to after. This was a single-arm study with no comparison group, so treat it as suggestive rather than definitive.
In a single-arm pre/post study of 22 COVID-19-positive patients in Pontianak, Indonesia, EFT was associated with significant reductions in anxiety, depression, and insomnia scores (p<0.05) from before to after.
Outcome study Preliminary
Tambunan, M., Suwarni, N., Selviana, S. · 2023
Forty-two people isolating with confirmed COVID-19 in Indonesia tried EFT to help with the anxiety, low mood, and sleeplessness that came with the diagnosis. All three measures improved significantly. This was a quasi-experimental study in a government isolation facility, so real-world conditions may have limited the rigor of the design.
EFT therapy was effective in reducing anxiety, depression, and insomnia scores among people confirmed positive for COVID-19 (p-value < 0.05).
Outcome study Preliminary
Lee, J.H., et al. · 2013
In a very small, uncontrolled study of ten older adults with insomnia, tapping was linked to a large improvement in depression symptoms measured on a geriatric depression scale. With no comparison group and only ten people, this is a preliminary early signal, not proof.
A large depression improvement (d=1.41) was reported in this very small (N=10), uncontrolled sample of senior insomnia patients.
Outcome study Preliminary Korean
Unknown, et al. · 2011
Ten older Korean women, average age in their mid-70s, struggling with insomnia tried a four-week group tapping program designed specifically for elderly sleep problems. By the end, their sleep, mood, anxiety, and life satisfaction all showed a real improvement — unlikely to be chance — and the sleep gains held up a month later. With only ten participants and no comparison group, this is best read as an early, promising pilot rather than proof.
Ten elderly women completed a 4-week EFT-I (EFT for insomnia) group program; all four outcome measures (sleep, depression, state anxiety, life satisfaction) showed statistically significant improvement (p<0.01), and improvement in insomnia continued at 4-week follow-up.
Case series Preliminary
Drewry, D. · 2017
This paper proposes that a specific type of sleep apnea (Central Nervous System, as opposed to the more common Obstructive type) is often caused by unresolved PTSD, and reports that most of 90 retrospectively reviewed clients improved when trauma was addressed using EFT and related techniques. The author explicitly acknowledges this is anecdotal, retrospective evidence without a sleep-lab-verified control comparison, and calls it a starting point for further research rather than proof.
Sixty-five percent of the author's 90 sleep apnea clients experienced partial or complete cessation of Central Nervous System Sleep Apnea by addressing specific trauma types using Energy Psychology techniques including EFT.
Review Preliminary
Church, D. · 2013
This review makes the case that a single EFT session can meaningfully help with phobias and certain anxiety disorders, and points to trial evidence that even one session lowers the stress hormone cortisol and normalizes stress-related brainwave patterns. It also cautions that more complex, co-occurring conditions like complicated PTSD need longer courses of treatment, not just one session. As a review and case discussion rather than a new trial, it doesn't carry its own participant count or effect size.
The chapter reports that randomized controlled trials show EFT effectively treats phobias and certain anxiety disorders in a single session, with a single session also producing a significant drop in cortisol and normalization of stress-associated EEG frequencies.
