Mitigation of EMF-induced Chakra and Meridian Imbalances/Dysfunctions by the Harmoni Pendant

Using a Wearable Device to Stimulate the Bioenergetic Centers in the Body affected by Electromagnetic Radiations

Summary:

As we strive for holistic approaches to improve human health, our exposures to electromagnetic fields (EMF) remain as one of the major barriers in that pursuit. Imbalance in energy pathways in the body is increasingly recognized as a precursor of stress and poor health, and as an avenue for therapeutic intervention in alternative as well as in conventional medicine. In this context, the current clinical trial evaluated the effect of a brief EMF exposure on the energy fields of seven major Chakras and 12 principal Meridians. EMF exposure dysregulated all of the seven Chakras and 10 out of the 12 Meridians resulting in a significant decline in the post-exposure evaluations compared to that of the pre-exposure baseline. By activating and wearing a Harmoni pendant, a non-electronic wearable device, there was a significant improvement in measured indices of Chakras and Meridians. Following the pendant activation, even in the presence of the EMF-stressor, there was up to 475% increase in Chakra function where six out of the seven chakras were completely recovered from their EMF-induced decline and registered a greater improvement over that of their baseline with a significant net gain. Additionally, the Harmoni pendant also improved all of the 12 Meridians fully compensating their EMF-induced decline, registering a sharp increase over their baseline values. In sum, results from this study clearly demonstrate the effectiveness of Harmoni pendant in balancing EMF-induced energy center dysfunctions and in managing sub-clinical stresses as a novel approach to advance bioenergetic health and wellbeing. 

Overview:

Chronic exposure to EMF is well known to interfere with multitudes of cellular and molecular processes affecting basic physiologic functions of energy metabolism, growth cycles, intracellular signaling and intercellular communications [1-7]. Oftentimes these interferences disrupt normal functioning of multiple organ systems that manifests in a number of adverse physical, behavioral and emotional health conditions [8-10]. A greater emphasis has been given to characterize the nature of EMF-induced “sub-clinical stress” and to understand its correlation with the underlying health conditions. Because of the slow onset and a lack of or non-specific symptomatic presentation, EMF-related health conditions, including the most aggravated form of Electromagnetic hypersensitivity, are often difficult for a definitive medical diagnosis and are rather self-reported [11-13]. In the absence of sensitive and reliable biomarkers and detection technologies, estimation of the EMF-induced burden on human health can be severely understated [14].

In our recent clinical study, a brief EMF exposure resulted in a sharp decline in 11 discrete health indices. This observation was indicative of EMF-induced autonomic dysfunctions and disruption in biological rhythms. In the pursuit to improve holistic health, mankind has been seeking insights from ancient healing techniques to understand the early aberrations in illnesses and to adopt and/or repurpose them for preventative and therapeutic purposes. The Chakra System, as described in ancient Vedic literatures, is a complex network of energy channels that operate in the body [15, 16]. Chakras are also referred to as “Energy Transducers” for subtle energy or life force in Energy Medicine that reflects connections between the Mind and the physical Body and has been the focus of numerous Psycho-Neuro-Immunology studies documenting the interactions between the endocrine, immune, nervous and stress response systems that greatly impact human functioning [17, 18]. While there are as many as 114 recognized Chakras, seven are considered major and are fundamental to the body’s subtle energy flow.

These Chakras with their functional associations are as following:

  1. Sahasra (Crown) chakra- Consciousness and Peaceful
  2. Ajna (Third Eye) chakra- Intuition and Perception
  3. Visudha (Throat) chakra- Creativity and Self expression
  4. Anahata (Heart) chakra- Warmth and Compassion
  5. Manipura (Solar Plexus) chakra- Strength and Assertiveness
  6. Svadhisthana (Sacral) chakra- Enthusiasm for Life and Pleasure
  7. Muladahara (Root) chakra- Foundation of energy body and Stabilization

Imbalance in the Chakra energy pathway is known to cause myriad of physical and mental health problems and a number of interventions have been used to put them into balance, including yoga, meditation, and sound, aroma, color and crystal therapies have been practiced in both Eastern and Western hemispheres.

Meridians, on the other hand, as described in traditional Chinese medicine, are energy pathways in the body and are anatomically aligned with major internal organ systems [15-18]. Meridians are also referred to as “Acupoints” as they can be stimulated by needling, pressure and heat treatment for clinical relief in alternative therapy [19, 20]. As Professor John C. Longhurst, MD, PhD, a pioneer in acupuncture hypertension research has reviewed the meridians are sophisticated stimulation centers and can serve as a doorway to bioenergetic healing [19].

There are 12 principal Meridians recognized in the body as below: 

  1. Meridian of the Heart
  2. Meridian of the Small Intestine
  3. Meridian of the Bladder
  4. Meridian of the Kidney
  5. Meridian of the Pericardium
  6. Meridian of the Triple Heater
  7. Meridian of the Gallbladder
  8. Meridian of the Liver
  9. Meridian of the Lung
  10. Meridian of the Large Intestine
  11. Meridian of the Stomach
  12. Meridian of the Spleen and Pancreas

Stimulation of meridians have been widely and successfully used in the management of musculoskeletal pain in the realm of alternative medicine where up to 70% of patients respond to acupuncture [20]. Since Meridians and Chakras represent apparatus for energy flow, there is a considerable functional overlap between them as these two systems work more in tandem than in isolation. In this context, a review on the nature of life energy as referred to as “Qi”, “Ki”, “Dosha”, “Prana”, “Mana”, “Etheric energy”, “Fohat”, “Orgone”, “Odic force”, “Homeopathic resonance”, “Quantum electrodynamics” etc in various literature.

It is generally accepted that the Chakra energy system is associated with the endocrine glands and neural centers of the autonomic nervous system (ANS). A balanced interaction between the Pineal, Pituitary, Hypothalamus, Thyroid, Thymus, Adrenal, Pancreas and Gonads is essential for optimal chakra functions and is deeply connected with the parasympathetic or “rest and digest” arm of the ANS. Therefore, it is plausible that measurement of ANS anomalies can be used to decode the imbalances in Chakra functions and Meridians.

EMF exposure is known to interfere with the ANS [8, 9] and heart rate variability (HRV), the variation in time intervals between successive heartbeats, has been a reliable measure of the autonomic activity [21, 22]. While a higher HRV is associated with optimal health, resilience and cognition [23-25], a lower HRV has been a predictor of poor health [26-28]. HRV-based evaluations are becoming the mainstay of health surveillance and have been recognized in almost all spectra of precision and personalized medicine. Since HRV mirrors autonomic activity, it is possible to extrapolate the status of various autonomic functions from the HRV measurement. In this context, the HeartScientific advanced HRV analytics developed by Therasage, LLC is notable as it has made significant strides in the HRV-based assessments that can numerically compute unique health indices including Chakra and Meridian functions and can provide a platform for an objective assessment of the body’s bioenergetic field.

While a number of approaches have been tried to block harmful effects of EMF radiation, efficacy of many EMF-minimizing or EMF-blocking products have not been independently and objectively evaluated. In this cross-sectional clinical study, we measured the efficacy of the Harmoni Pendant in mitigating EMF-induced bioenergetic imbalances in boosting the body’s resilience and adaptability.

Objectives:

  • To decipher and measure the energy imbalances in Chakra and Meridian systems induced by a short-term exposure to a non-ionizing EMF as evidenced by the HeartScientific advanced HRV analytics
  • To assess efficacy of activating a Harmoni Pendant in stimulating Chakra and Meridian without the withdrawal of the stressor

Study Methodology:

A multicentered, single-armed and open-label study was conducted at eight (8) healthcare locations across the United States between March 2020 and Aug 2020. A total of 95 consenting healthy subjects (male or female, >18y) were enrolled in the study. Prior or current users of Harmoni Pendant were excluded from this study. Additionally, subjects using any other EMF protection devices were also excluded. The study was designed to measure Chakras and Meridians at three (3) time points using HeartScientific advanced HRV technology (schematics of the schedule of events shown in Fig. 1). Study data were collected at:

  • Baseline (with no source of EMF in the vicinity)
  • After introduction of a high EMF source
  • After activation of the Harmoni Pendant in presence of the EMF source

Prior to the study, we tested many appliances and found a small portable fan to be a reliable source of consistent and high-level EMF. Cell Phone EMF output proved to be inconsistent and varied between brands.

The absence of EMF was confirmed by Gauss meter reading at baseline, and presence of EMF was confirmed by Gauss meter readings after introduction of the EMF-stressor and after activation of the Harmoni Pendant. The HRV scans were conducted by placing electrodes on patient’s wrists following the manufacturer’s recommended protocol (representative image, Fig. 2). Since the study did not involve any invasive testing or procedures, it was deemed a minimal risk study. The HRV scan data was utilized to construct a comparative report by HeartScientific Advanced HRV Software Version 9.7. The subject datasets were anonymized, following which they were analyzed by JMP Pro (15.0.0) and Prism 8 (8.4.3) for statistical comparisons. 

 Fig 1: Schematics of the study details.

The datasets were transformed to measure percent (%) change by the following formula:

 

Percent change following EMF-stress:

[(EMF Stressed-Baseline)/Baseline]*100

 

Percent change following Pendant activation:

[(Pendant activated-Baseline)/Baseline]*100

 

A one-tailed paired T-test was applied to discern significant differences between EMF-stressed and pendant-activated time points. References were prepared by EndNote (X9).

The Heart Scientific Advanced HRV Technology was developed by a team of experts in software development, healthcare and HRV analytics at Therasage LLC, known as an industry leader in integrated FDA listed medical devices, that harness full spectrum infrared frequencies. In a collaborative effort with Dinamika Research from St Petersburg, Russia, also considered the gold standard in HRV software development since 1964, HeartScientific Advanced HRV analytics is the most robust and comprehensive Advanced HRV diagnostics available today.

The HeartScientific Advanced HRV is a digital bioanalyzer that measures fractal neurodynamics and biorhythms in the body from the electrocardiogram signals. The Advanced HRV device, having a small footprint, is highly portable and does not require a specialized training to operate. It is offered as a hardware-software combo that provides an intuitive user interface and creates easy to interpret infographic reports suitable for use at home and at healthcare clinics in tracking individual’s wellbeing on the health continuum.  

A 5-min scan for the Time-domain and Frequency-domain HRV measurements was conducted to calculate the functioning of a total of 19 bioenergetic centers (7 Chakras and 12 Meridians).

Results:

The study participants had a median age of 44 years (range 18-73 years). Fifty eight percent (58%) of the study participants were females whereas males constituted the remaining 42% of the study population (Table 1). 

Our previous study had demonstrated a negative impact of EMF exposure on the HRV-index whereas activation of Harmoni Pendant (in the presence of the EMF source) was effective in boosting the HRV-index and reducing stress among many other health benefits. The current study, utilizing the same study design, had a primary focus on evaluating the energy fields and energy pathways as measured by the HeartScientific Advanced HRV.

A brief exposure of EMF had a deleterious effect on all of the seven major Chakras. The average decline ranged from 2.16% to 10% from the baseline with Sacral Chakra (associated with reproductive health) experiencing the maximum drop of 10% on an average from the baseline. (Table 2, Fig. 3). Activation of the Harmoni Pendant, on the other hand, stimulated all of the seven Chakras registering greater functioning than their baseline values (Fig. 3). While the Harmoni pendant was effective in fully neutralizing the negative effects of EMF, the Chakra fields on average were upregulated up to 475%. Although the seven Chakras experienced a varied level of activation, the Crown Chakra and Root Chakra experienced the greatest stimulation from the activation of Harmoni Pendant (Table 3).  

Analysis of the Meridians also registered an EMF-induced negative impact. Ten out of the 12 Meridians studied, on average, suffered a loss of Meridian function following EMF-exposure compared to that of their pre-EMF exposure baseline (Fig. 4, Fig. 5). Meridians of Large intestine and Meridian of Stomach were however the two meridians that did not experience any significant differences by the brief EMF-exposure studied here. The response to pendant activation was however striking where all of the 12 Meridian functions were elevated above their respective baseline values. Additionally, this rise in Meridian function fully compensated the EMF-induced declines as earlier observed in case of 10 meridians.

The summary of the Harmoni pendant stimulating Meridian function is presented in Table 4. While the functioning of all 12 Meridians improved following Pendant activation, three key trends with high stimulation were: 1) activation of the Meridians for Pericardium and Heart signifying an improved cardiovascular health, 2) activation of the Meridian for Liver, Gallbladder and Small Intestine indicating a robust nutrient metabolism and digestive health, and 3) activation of the Meridians for Lung and Kidney suggesting improved respiratory and glomerular functions implying vigorous detoxification processes.

Discussion:

As we progress through the 21st century, our increasing dependency on connectivity and drive for efficiency in modern life is causing sustained exposure to various sources of manmade EMF radiation. Even though the health impacts of chronic EMF exposure can vary, from poor sleep and fatigue to cellular dysfunction, full extent of the EMF-induced harmful effects of EMFs are not generally understood. Slow onset and below clinical threshold for discernible symptomatic diseases, coupled with a lack of sensitive biomarkers for early detection of EMF-induced sub-clinical stress are obvious contributing factors. Interventions to block or mitigate EMF-induced stress are limited and are not backed by objective assessments in clinical settings. 

The efficacy of Harmoni Pendant was demonstrated in stimulating the Chakra fields and balancing the negative effects of EMF. While optimal performance of the seven major Chakras is needed to live a full-fledged life, suboptimal performance of a Chakra is referred to as a “blocked Chakra”. The hazardous nature of EMF was evident as even a brief exposure (for ~5 mins) remarkably blocked all seven Chakras with Sacral Chakra (associated with vitality) experiencing the maximal blockage. It is noteworthy that the Harmoni Pendant unblocked or restored energetic flow and function to the seven Chakras and registered a net positive effect from the baseline. Crown Chakra that is associated with higher consciousness and spiritualism was one of the most activated energy pathways by the Harmoni Pendant. Additionally, greater activation of the Root Chakra that reflects basic bodily needs was indicative of improved grounding and stability. These results clearly suggest that merely wearing a Harmoni Pendant can provide a meaningful difference in protecting from the EMF induced disruptions and in achieving a harmonious life balance.

Since Meridians can be better mapped with imaging techniques, they have provided a reliable avenue for therapeutic interventions. Similar to the EMF-induced decline in Chakra fields, a vast majority of the Meridians also suffered a loss of function from EMF exposure. These disruptions to Meridians were however reversible and activation of Harmoni pendant resulted in a full recovery oftentimes boosting greater functionality over that of the pre-exposure baseline. 

While the finding of this study has a great significance in Energy medicine and relevance in Holistic health improvement, the energy field and pathway measurements were purely based upon HRV analytics. Absence of clinical correlation such as subject level questionnaire or independent assessment could be seen as a limitation to this study. However, the HeartScientific advanced HRV tech offers a robust platform for analysis of energy fields validated by years of practice. 

It is also important to note that the current study evaluated the biological effects of EMF on the human body and Harmoni Pendant usage for a relatively short period of time (5-10 minutes). Longer usage and weekly activation of the Harmoni Pendant most likely may harness a much greater impact in stimulating and balancing the energy fields.

Our observations with thousands of Harmoni Pendant wearers indicate that it takes about 3-4 days for all health benefits to unfold as the body regulates physical functioning after receiving new information or instructions from the Pendant. It is momentous that the Harmoni Pendant had such a short “time-to-effect” with unblocking and balancing the bioenergetic dysfunctions that could be a precursor to health and healing.

 

Conclusion:

Data from this study show that activation of a Harmoni Pendant may effectively minimize EMF-induced bioenergetic dysfunctions and imbalances in the human body. The findings also illustrate a range of health benefits that can be achieved from an optimal functioning of the body’s energy fields. The results strongly support inclusion of the Harmoni Pendant, worn as a necklace, for building an effective personal shield against omnipresent EMFs and for energy healing to improve overall physical and emotional well-being.
