Before We Begin: A Note on Evidence
This article reports the findings of published systematic reviews and peer-reviewed studies exactly as the researchers stated them — including their limitations. Biofield therapy is an emerging field with a growing but still-developing evidence base. We distinguish between strong, moderate, and equivocal evidence throughout, and link every claim to its source so you can read the original research yourself. Bio-Well is a measurement tool, not a therapy — it measures; it does not treat.

What Are Biofield Therapies?
The NIH defines biofield therapies as noninvasive, practitioner-mediated therapies that explicitly work with the biofield of both the practitioner and client to stimulate a healing response in the client. This definition was established in 1994 when biofield therapies were officially recognized as a category of complementary medicine by the NIH.
The most widely studied biofield therapies include:
Reiki
88 published studies in the 2025 scoping review
Therapeutic Touch
71 published studies
Healing Touch
31 published studies
External Qigong
16 published studies

The Systematic Reviews: What 353 Studies Found
Two major systematic reviews provide the most comprehensive assessment of biofield therapy evidence. Here is exactly what each found — in the researchers' own characterizations:
Additional perspective from the 2015 Jain et al. clinical review
The 2015 review in Global Advances in Health and Medicine — co-authored by researchers from UC San Diego, The Institute for Integrative Health, and the Consciousness and Healing Initiative — characterized the overall state of evidence as: "promising but limited evidence based on relatively few studies with insufficient sample sizes as well as methodological issues that could be improved."
Evidence by Condition: Strong, Moderate, or Equivocal
Based on the Jain & Mills best-evidence synthesis criteria, here is how the evidence levels break down by condition. Each rating is directly from the published review — not our characterization:
| Condition / Outcome | Evidence Level | What This Means |
|---|---|---|
| Pain intensity (pain populations) | STRONG | At least 2 high-quality RCTs with minimal to no conflicting evidence. Several studies had large effect sizes. |
| Pain (hospitalized patients) | MODERATE | Positive results from multiple studies but with some conflicting or lower-quality evidence. |
| Pain (cancer populations) | MODERATE | Supported by multiple studies with positive trends, though sample sizes are often small. |
| Behavioral symptoms in dementia | MODERATE | Decrease in negative behavioral symptoms observed across multiple studies. |
| Anxiety (hospitalized patients) | MODERATE | Consistent anxiety reduction observed across studies in hospitalized populations. |
| Fatigue / quality of life (cancer) | EQUIVOCAL | Mixed results — some positive findings offset by conflicting or null results in other studies. |
| Anxiety (cardiovascular patients) | EQUIVOCAL | Insufficient consistent evidence to draw conclusions for this specific population. |

The Limitations: What the Research Hasn't Yet Shown
Intellectual honesty requires stating not just what the evidence supports but where the gaps are. Multiple systematic reviews have identified consistent limitations in biofield therapy research:
Sample sizes are often small
The 2015 clinical review noted "relatively few studies with insufficient sample sizes." Larger, multi-center trials are needed to confirm preliminary findings.
Blinding is difficult
It is inherently challenging to blind participants to whether they're receiving a biofield therapy vs. a sham treatment. This can introduce placebo effects that are hard to control for.
Inconsistent reporting
The 2025 scoping review found that inconsistent reporting across studies contributes to inconclusive findings and hinders integration into mainstream medical systems.
Mechanism is not fully understood
While the biofield concept is consistent with bioelectromagnetics, the precise physical mechanism by which practitioner-mediated biofield therapies produce clinical effects remains an area of active investigation.
These limitations are real and widely acknowledged in the research community. However, as the 2025 scoping review demonstrated, the volume of research is growing rapidly — with 255 RCTs now published and new reporting guidelines (BiFi REGs) being developed to improve future study quality.

How Bio-Well Fits In: Measurement, Not Treatment
An important distinction
Bio-Well is a measurement device, not a therapy. It does not treat conditions. What it does is allow practitioners to observe and quantify energy field changes — including changes that may occur before and after biofield therapy sessions. This measurement capability is valuable because it addresses one of the key limitations identified in the systematic reviews: the lack of objective outcome measures.
Published studies using Bio-Well's GDV technology have documented measurable changes in scan parameters following various therapeutic interventions. Here is what the specific studies reported:
After osteopathic manipulation
A published study reported statistically significant changes in GDV parameters in patients and practitioners following osteopathic treatment sessions.
After massage therapy
Significant differences were found between pre- and post-measures. GDV parameters correlated with self-reported pain and stress — suggesting the GDV measurement reflected the same changes patients felt subjectively.
After yoga and naturopathy
A randomized controlled study used Bio-Well to measure changes in children with autism following a 24-day yoga and naturopathy program, reporting observable shifts in biofield parameters.
Note: These studies demonstrate that Bio-Well can detect measurable changes following interventions. They do not, on their own, prove that the therapies caused the changes — factors like relaxation, passage of time, or placebo effects could contribute. This is why the broader systematic reviews call for more rigorous study designs with proper controls.
How to Explore Biofield Therapies
If you're interested in biofield therapies, the strongest published evidence supports them as a complement to — not a replacement for — conventional medical care. Here's how to approach them thoughtfully:
🔬
Get a baseline scan
A Bio-Well scan before starting any therapy gives you objective data to compare against later. This is how practitioners track whether interventions are producing measurable shifts.
🤝
Choose certified practitioners
Look for practitioners with formal training in their specific modality (Reiki, Healing Touch, etc.) and in Bio-Well scan interpretation if using it as a tracking tool.
📊
Track over time
A single scan is a snapshot. Multiple scans over weeks or months reveal trends — which is far more informative than any single measurement point.
⚕️
Complement, don't replace
Biofield therapies are best used alongside conventional medical care. Always consult your healthcare provider for any medical condition.
