Biofield & Biofield therapy research
A biofield therapy is, “a non-invasive, complementary, and alternative medicine (CAM) practice that involves manipulating the body's supposed "subtle energy fields" (biofields) to promote healing, reduce stress, and improve well-being” (Jain S, Hammerschlag R, Mills P, et al). Biofield therapies are now being studied, and taken more seriously by many scientists world wide…which is incredibly exciting. You are probably familiar with more biofield therapies than you think; reiki, sound healing, qigong, healing touch, etc.
Biofield studies originated from a combination of ancient energetic healing practices and early 20th-century scientific discoveries regarding electrical and light emissions from living organisms. Formally, the term "biofield" was coined in 1992 by the National Institutes of Health (NIH) to define a, "massless field, not necessarily electromagnetic, that surrounds and permeates living bodies" (Google. (2026). Gemini (March 2 version) [National Institutes of Health (NIH)]. https://gemini.google.com/).
Biofield studies give us new terminology and new studies to support the benefits of these practices. These studies not only look into the benefits, but are attempting to understand the mechanisms behind how they work. There are many difficulties that come with trying to create what would be considered legitimate studies around these practices, due to many factors such as: funding, double blind procedures, definitions, practitioners, styles (in person and distant), and other variables.
”A key issue in increasing awareness of this area of study is educating healthcare workers and the general public about biofield theory and research. Because biofield therapies do not involve the use of invasive agents like medication, needles, or supplements and because they invoke concepts that are somewhat foreign to many allopathically trained physicians, discussion around stimulating a healing response by working with energy fields often elicits responses that the entire field of study is fraught with pseudoscience. A significant challenge for this field of study is presented by otherwise well-meaning practitioners and advocates who describe or utilize ill-designed scientific methods to “prove” that their method of healing works. These efforts increase barriers to conducting this work. However, in many cases, the barriers are more due to a general lack of conceptual knowledge about biofields and the need to explain hypotheses about biofields in a manner that can be understood and to ensure that people are educated on the state-of-the-evidence and most salient gaps in the research” (Jain S, Hammerschlag R, Mills P, et al).
So let’s take a second to back up, let’s define biofield in it’s relation with the body before we continue talking about the biofield therapies.
Biomagnetic fields are weak magnetic fields produced by the electrical current activity in the human body. Cells, tissues, organs, etc. produce these fields within the body. The heart generates the strongest biomagnetic signal within the body. This field not only interacts with us, but with those around us and we are impacted by fields outside of us in return. The heart’s magnetic field can be measured several feet out from the body. “Compared to the electromagnetic field produced by the brain, the electrical component of the heart’s field is about 60 times greater in amplitude and permeates every cell in the body.” (Tuning The Human Biofield, Pages 92-93). The heart radiates this field outside the body to the space around us & can be measured by HRV. This emanating field is dynamic, changing based on our emotional state (HeartMath Inst,). These fields can be measured by SQUID sensors (superconducting quantum interference device).
The heart produces either coherent or incoherent frequency patterns based on the emotions a person is feeling. A coherent frequency is ordered, consistent, clear, and in phase. When our bodies achieve states of coherence, we are at our best. In this state, our nervous system, heart, and brain sychronize. We experience better cognitive function, emotional stability, and other psychological benefits. Love, appreciation, gratitude cause the heart to produce coherent frequencies, allowing the body to function more effectively, whereas frustration, anger, etc, can cause incoherent frequencies and disruption and stress within the body. Our emotions translate to electrical patterns and frequencies.
As humans, we have a fundamental bioelectric system. The electric communication system of our body is incredibly complex. An INCREDIBLY oversimplified breakdown of the electrical functions within our body goes like this:
Our nervous system conducts electrical signals
The collagen within our body acts as a semiconductor
Our emotions are electrical-chemical events
Our blood carries a charge
Our bones are semi-conductive/transduce electricity
Our brainwaves are electrical frequencies
Our heart is an electrically driven oscillator
Those are just some examples to show you just how bioelectric our system is!
Okay so coming back to the question- what is our biofield?
“It is “a complex, dynamic, and weak electromagnetic field that both surrounds and permeates the human body. It acts as a field-based regulator of physiology and biochemistry, functioning as a "blueprint" that coordinates life processes and reflects an individual's state of health.” - Dr. Beverly Rubik NIH
The electromagnetic properties within each part of us are contributing to complex frequencies that permeate the body and can change overtime. Electromagnetic bioinformation plays a crucial role in regulating functions within the body, and this information is encoded within the frequencies emitted in our biofield. You can think of our biofield like the sheet music to the entire orchestra. When there is a disruption within our system- or a note playing out of tune, that in theory is reflected within our biofield- the extent of this is still being researched. Then on top of that- our sheet music only translates our inner orchestra, but interacts with everyone’s else’s sheet music and orchestra as well. You can see how complicated this can become.
It has already been shown in research conducted at HearthMath that our emotions impact the state of our biofield. Furthermore, studies have suggested that this biofield can be impacted by other biofields, conscious intention, leading to altering biological and physical states. HeartMath research has shown that when people were able to maintain the coherent state of mind, that they were less effected by fields of others emanating around them.
One area of study is focusing on the effect and ability humans possess to be impacted by the energetic field emitted from the heart.
...The results of these experiments have led us to conclude that the nervous system acts as an antenna, which is tuned to and responds to the magnetic fields produced by the hearts of other individuals. My colleagues and I call this energetic information exchange energetic communication and believe it to be an innate ability that heightens awareness and mediates important aspects of true empathy and sensitivity to others. Furthermore, we have observed that this energetic communication ability can be enhanced, resulting in a much deeper level of nonverbal communication, understanding and connection between people. We also propose that this type of energetic communication between individuals may play a role in therapeutic interactions between clinicians and patients that has the potential to promote the healing process. From an electrophysiological perspective, it appears that sensitivity to this form of energetic communication between individuals is related to the ability to be emotionally and physiologically coherent. The data indicate that when individuals are in the coherent state, they are more sensitive to receiving information contained in the magnetic fields generated by others. In addition, during physiological coherence, internal systems are more stable, function more efficiently and radiate electromagnetic fields containing a more coherent structure (Heartmath Institute). The level of successful energy-communication varied once the physical touch was removed, and individuals were separated by greater distances
Okay to recap- the heart is the largest source of biomagentic energy in the body, emitting our biofield out several feet from us. Within our body are other biofields being emitted, even down to the celluar level. HOWEVER- biofields are not limited to just our bodies. Any living thing emits a biofield- the planet has an incredibly complex system of magnetic fields. It is also important to understand that “‘biofields’ do not just apply to ‘biofield therapies’ but rather are relevant to the mechanisms by which mind and body interact to promote healing responses (Jain S, Hammerschlag R, Mills P, et al).
So let’s talk about the placebo effect. Many people wonder if CAM therapies are just really masked placebo effects- that it doesn’t really do anything we just believe that it does, so it does. To be clear if it isn’t already, we need more research. Nothing in this article aside from results of study are for sure.
What has been suggested about the placebo effect so far in studies of CAM therapies is as follows; “Current data suggest it is unlikely that biofield therapies are reducible to placebo responses alone, but like other forms of mind-body medicine interventions and biomedicine in general,60,61 biofield therapy may intentionally harness the patient's conscious and unconscious expectancies and desires in synergy with the treatment being delivered to enhance outcomes” (Jain S, Hammerschlag R, Mills P, et al).
So, what you believe about your treatment, like many other treatments, will impact the quality of your healing and experience of the treatment CAM or not, but it does not appear that CAM is operating on the placebo effect alone.
So what are we looking for when we study CAM modalities? That is one of the barriers with studying these modalities. We don’t fully understand how they work- so what do we look for? We have to start generally and work our way into more detail until we have a better idea of how these modalities are working- though I will point out just because we don’t understand the mechanism does not mean they do not work or are not important modalities.
”There has been confusion, by both researchers and funders, regarding the need to include analysis of potential mechanisms in early stage clinical studies of biofield therapies. As with other controversial healing modalities, there is pressure to demonstrate “biologically plausible mechanisms” of biofield therapies. We argue that elucidating mechanisms, while important in helping to understand and even improve upon a therapy's effects, is not essential for conducting rigorous and potentially informative clinical trials of any therapy…exploration of potential moderators and mediators of treatment may lead to better empirically based hypotheses for testing mechanisms of biofield therapies.” (Jain S, Hammerschlag R, Mills P, et al).
We do not fully understand chronic pain issues, yet here are thousands of people dealing with chronic pain to seemingly no end in sight. Thousands of years of civilizations and cultures have used these modalities without understanding the exact mechanisms of how they work and have still reported experiential success. It is just exciting we are finally at a time in the scientific-social arena that people are beginning to take it seriously enough to study and move slowly into mainstream.
It is important to remember that biofield studies, may and in my opinion will most likely be inclusive of multiple different fields. Which means, understanding the mechanisms of what is happening is a tall order that will take many great minds across multiple fields working together to connect research that has already been completed, and the research that needs to be done.
“A key hindrance to understanding potential mechanisms of biofield therapies is the absence of a reliable measure of the purported biofield emanations from the practitioners. While there have been a few reports regarding emanations from certain practitioners,54–56 creating a systematic method to examine such bioenergetic signals is a crucial step to better understand the physiological basis of biofield therapy. The development of systematic methods examining bioenergetic signals from practitioners may help us better understand, for example, whether the efficacy of the healing interaction is directly proportionate to the strength of the biofield emanation, to a particular pattern of biofield emanation, or whether there are other factors apart from or in addition to bioenergetic signaling that significantly contribute to the outcomes of the practitioner/client encounter. As interested engineers and scientists further develop techniques to measure emanations from practitioners at different electromagnetic frequencies, it will be of interest to determine whether specific patterns of bio-energy emanation are predictive of better healing outcomes. At the same time, there are potential pitfalls from assuming that electromagnetic emanations are the sole explanation for the experience and practice of biofield therapies,50 as they would not account, for example, for the results of distant healing studies carried out in electromagnetically shielded environments (see Radin et al, this issue) 57, 58” (Jain S, Hammerschlag R, Mills P, et al).
While we don’t fully understand what is happening or how, that has not stopped the studies from happening and the results reported from them are promising.
“In terms of current biofield therapy research, several studies have examined more “global” biomarkers such as HRV and/or single measures of cortisol or natural killer cell cytotoxicity as outcomes either in healthy or specific clinical populations.12,13,16,18,29,38–41,43,65–68 Such markers were chosen for ease of acquisition/feasibility and potential relevance to the clinical population being studied. Reported changes in these specific outcomes suggest that biofield therapies have positive effects on physiological processes of clinical relevance” (Jain S, Hammerschlag R, Mills P, et al).
There have been many studies of CAM practices that have reported general improved tracked markers, and improved positive outlooks reported by participants such as with: anxiety, depression, stress, blood flow, heart rate, connection, peace, pain perception, inflammation, pain, and PTSD.
A study was done on The Effects of Singing Bowl Sound Meditation on Mood, Tension, and Well-Being: An Observational Study. “Heart disease, diabetes, addiction, and mental health issues have all been linked to stress and tension”, and, “poor mood and elevated anxiety are linked to increased incidence of disease”, this study wanted to focus on how sound meditation could effect anxiety, pain, mood, and spiritual well being (Goldsby, T. L, et al).
“Following the sound meditation participants reported significantly less tension, anger, fatigue, and depressed mood...Feeling of spiritual well-being significantly increased across all participants” (Goldsby, T. L, et al). The authors noted many benefits to sound meditation along with the significant positive patient results: low-cost technology and a low learning curve for patients being two positives for easy integration for clinical use. Patients reported decreased pain, decrease mental anxiety, increased spiritual connection, along with measurable effects of lowered blood pressure and heart rate. A similar study was done using singing bowl therapy with metastatic cancer patients, and chronic spinal pain patients, and many positive results were reported. “Improvements in distress, positive and negative affect, anxiety, depression, fatigue, tension, anger, confusion and vigour were reported, as were improvements in blood pressure, heart rate, respiratory rate, peripheral capillary oxygen saturation, cutaneous conductance, and anterior-frontal alpha values” (Stanhope, J., & Weinstein, P. ).
Along with sound, distance healing and in person energy healing has been studied. One particular study was a randomized, placebo-controlled, three parallel-groups, double-blind, and single-center with subjects who have one or more psychological and mental symptoms. The conclusion was that, “The distant (virtual) biofield energy healing therapy significantly improved psychological and mental health-related symptoms without affecting safety concerns, and improved overall health and quality of life.” (Trivedi MK, Branton A, Trivedi D, et al). Another randomized control trial of in person reiki healing was done, and reached similar conclusions. “The existing meta-analysis and systematic review suggested that Reiki therapy positively impacted quality of life. Therefore, it was recommended that patients with cancer, surgical patients, chronic illnesses, and the general population receive acute Reiki therapy sessions (≤ 20 min) or Reiki therapy with sufficient frequency (≥ 8 sessions) and duration (≥ 60 min) to enhance their quality of life” (Liu K, Qin Z, Qin Y, Li Y, et al).
In short, studies show that these modalities are working, but we don’t fully understand how, and more studies are needed. Overall the two areas that have received the most research with biofield therapies, are cancer and pain, showing positive results in using biofield therapies. So far, another benefit of biofield therapies is that there are considered low risk, with very few, if any ever negative side effects.
So overall, this topic is incredibly complex…but also incredibly exciting. We are at a pivotal shifting moment in the story of the science social arena. What people have known and practiced for thousands of years is finally being taken seriously, and more than just taken seriously, validated. We have a long way to go, but we are finally starting.
