The Truth About Tapping

[Read the full research paper (PDF)]

Let’s be fair. If you’ve never seen Thought Field Therapy (TFT) before, watching someone tap on specific points around their face and body while focusing on an emotional problem might seem a little unusual.

How could something so simple help someone manage stress, fear, anxiety, or difficult memories?

It’s a reasonable question. And it’s one that researchers have been investigating for years.

A research review published in November 2025 in the peer-reviewed journal Frontiers in Psychology brings together findings from clinical trials, neuroscience, and physiological studies to explore what happens when people use therapeutic tapping techniques.

The findings offer some intriguing explanations for a method that has often been misunderstood.

First, what exactly is Thought Field Therapy?

Thought Field Therapy (TFT) is a therapeutic tapping method developed by psychologist Dr. Roger Callahan. It combines focused attention on a particular emotional concern with tapping sequences on designated points of the body.

Unlike conventional talk therapy, TFT introduces a physical component. While thinking about a troubling situation, feeling, or memory, the person taps on specific points associated with traditional acupuncture systems.

The goal is to help reduce the emotional distress associated with that concern.

TFT also helped establish the foundation for a broader family of approaches sometimes called energy psychology, including Emotional Freedom Techniques (EFT), which developed later.

What does the research say about tapping?

In his 2025 review, How Tapping Works: Physiological and Psychological Mechanisms in Energy Psychology Treatments, researcher David Feinstein examined more than two decades of published research on acupoint tapping.

The review discusses a research database containing more than 200 English-language peer-reviewed clinical trials of TFT and EFT, including randomized controlled trials, along with additional studies published in other languages.

Many of these studies reported improvements in symptoms associated with stress, anxiety, depression, and trauma.

That’s encouraging. But there’s an important distinction: much of the research examines EFT, rather than TFT specifically. Although the two approaches share important features, findings from one cannot automatically establish the effectiveness of every technique used in the other.

The review also acknowledges limitations in the research, including small study sizes, potential bias, and the need for stronger comparisons with established treatments.

Still, the growing research literature raises a question worth exploring: What might be happening in the brain and body during tapping?

What happens in the brain when we tap?

One of the most interesting developments in tapping research involves the relationship between physical stimulation and emotional regulation.

When we experience fear, anxiety, or emotional distress, several brain systems become involved. Among them is the amygdala, which plays an important role in recognizing and responding to potential threats.

Researchers are investigating whether tapping on specific points of the body can influence neural activity associated with these emotional responses.

The 2025 review describes a proposed process in which physical stimulation of acupoints generates sensory and electrochemical signals that may influence brain regions involved in emotional processing.

In simpler terms, tapping may help the nervous system respond differently to something that previously triggered distress.

This is a developing area of research. Scientists have not yet established every step of the proposed mechanism, but neuroimaging and physiological studies are helping researchers explore the possibilities.

It’s not just about how people say they feel

One common criticism of psychological treatments is that their results often depend on self-reported feelings.

Someone says they feel calmer. But can that change be measured?

Researchers studying tapping have begun looking beyond questionnaires and personal experiences to examine physiological changes.

Cortisol and the stress response

Cortisol is a hormone involved in the body’s response to stress.

In one study discussed in the review, participants receiving an EFT session experienced an average cortisol reduction of 24.4%, compared with 14.2% in a supportive counseling group and 0.6% in a no-treatment group.

A later study reported an even larger reduction in its EFT treatment group.

These findings are interesting because they suggest that tapping interventions may be associated with measurable physiological changes, not simply changes in how participants describe their emotions.

However, cortisol naturally fluctuates, and individual studies do not establish that TFT produces the same results. Larger, well-controlled studies are needed to better understand these effects.

Other physiological changes

The review also discusses preliminary findings involving:

• Heart rate variability, a measure associated with autonomic nervous system regulation.
• Changes in brain activity observed through neuroimaging.
• Immune-related biological markers.
• Possible changes in gene expression associated with stress and emotional regulation.

These areas remain under investigation, but they point toward an important shift: tapping is increasingly being studied through measurable biological and neurological processes.

Why might tapping help with difficult memories?

Think about a memory that still makes you uncomfortable.

Even though the experience happened in the past, remembering it can sometimes bring back the same emotional reaction.

One explanation being explored in tapping research involves a process called memory reconsolidation.

When a memory is recalled, the brain may temporarily become capable of updating certain aspects of that memory, including its emotional associations.

Researchers propose that focusing on a troubling memory while experiencing reduced emotional arousal may help change how strongly that memory triggers distress.

The experience isn’t necessarily forgotten. Instead, the emotional response associated with remembering it may become less intense.

This is one proposed explanation for why some people report rapid and lasting improvements following tapping treatments. Its precise role in TFT and EFT still needs direct experimental confirmation.

What about the word “energy”?

The term energy psychology can create confusion, especially among people unfamiliar with the history of tapping methods.

Early explanations drew on traditional concepts of energy pathways associated with acupuncture and Eastern healing practices.

These historical ideas are different from the measurable electrical and chemical processes studied in modern neuroscience.

Today, researchers are increasingly examining tapping through the lens of sensory stimulation, nervous system activity, emotional regulation, and psychological learning.

That doesn’t mean every traditional explanation has been scientifically validated. It means researchers have new ways to investigate what may be happening during tapping.

So, does Thought Field Therapy actually work?

The most useful answer is that research on acupoint tapping has produced promising findings, while important questions remain.

Clinical studies of TFT and EFT have reported improvements across several psychological concerns. Research on EFT is more extensive, and the evidence varies by condition, study quality, and treatment protocol.

The 2025 review presents a strong case for further investigation and clinical consideration of tapping approaches. It is also important to recognize that its author is an established advocate and educator in energy psychology, and that some researchers continue to question the strength of the evidence.

That’s how scientific understanding develops: through testing, replication, critical evaluation, and a willingness to revise explanations as new findings emerge.

For Thought Field Therapy, the growing interest in physiological and psychological mechanisms is particularly meaningful.

It moves the conversation beyond whether tapping looks unusual and toward a more useful question: What can careful research tell us about how it works, who it may help, and where its limitations lie?

Frequently Asked Questions About TFT Tapping

Does Thought Field Therapy really work?

Some studies of Thought Field Therapy and related tapping approaches report reductions in emotional distress, anxiety, and trauma-related symptoms. However, the evidence varies in quality, and additional rigorous research is needed to establish effectiveness for specific conditions.

How does TFT tapping work?

Thought Field Therapy combines focused attention on a specific emotional concern with tapping sequences on designated points of the body. Researchers have proposed several possible mechanisms involving attention, physiological arousal, and emotional processing, but the precise mechanisms remain uncertain.

Is there scientific research supporting tapping?

Yes. Published studies and reviews have investigated Thought Field Therapy and related tapping interventions. Some report promising outcomes, although findings from different tapping methods cannot automatically be generalized to TFT, and further high-quality research is needed.

Is TFT the same as EFT tapping?

Thought Field Therapy (TFT) is the original tapping method, developed by psychologist Dr. Roger Callahan. It laid the groundwork for Emotional Freedom Techniques (EFT), which emerged later. While both approaches use tapping on specific points of the body, TFT offers structured tapping algorithms and advanced diagnostic procedures that distinguish it from EFT.
