The Science behind PEMF
PEMF therapy, which stands for Pulsed Electromagnetic Field therapy, is a cutting-edge, non-invasive treatment that harnesses the power of electromagnetic fields to activate your body's natural healing potential. By mimicking the Earth's protective magnetic field, PEMF therapy unlocks a spectrum of wellness benefits that complement our holistic approach to mind and body wellbeing. Our carefully selected devices, including the CELLER8 and our premium PEMF mats, deliver these therapeutic fields with precision, making advanced biohacking accessible and effortless for everyone seeking to optimise their health journey.
How PEMF works
Every cell within the human body relies on electrical activity to function. From nerve impulses and muscle contractions to cellular communication and repair, tiny electrical signals help regulate countless biological processes that keep us healthy.
Pulsed Electromagnetic Field (PEMF) therapy works by delivering carefully controlled electromagnetic pulses that interact with the body's own natural electrical systems. These low-frequency magnetic fields pass safely through the body and induce microscopic electrical currents within tissues, supporting normal cellular activity and helping maintain healthy biological function.
Unlike many wellness technologies that work only at the surface, PEMF reaches deep into muscles, joints and connective tissues without discomfort, making it an increasingly popular tool in recovery, performance optimisation and long-term wellbeing.
Supporting Cellular Energy
One of the most researched areas of PEMF therapy is its effect on cellular energy production.
Every cell generates energy through structures called mitochondria, often referred to as the "powerhouses" of the cell. These produce adenosine triphosphate (ATP), the molecule responsible for powering virtually every biological process, from muscle contraction and tissue repair to brain function and immune activity.
Research suggests that appropriately applied PEMF may help optimise mitochondrial function by supporting the movement of electrons within the cell's energy-producing pathways. More efficient energy production means cells have greater resources available to perform their normal maintenance and recovery processes.
While PEMF is not a substitute for healthy nutrition, exercise or sleep, many researchers believe improved cellular energy production is one of the key mechanisms behind its reported benefits.
Improving Circulation and Oxygen Delivery
PEMF has also been shown to influence the body's production of nitric oxide (NO), a naturally occurring signalling molecule that plays an important role in vascular health.
Nitric oxide encourages blood vessels to relax and widen, supporting healthy circulation throughout the body. Improved blood flow enhances the delivery of oxygen and nutrients to tissues while assisting with the removal of metabolic waste products.
Healthy circulation is fundamental for exercise recovery, muscle performance and the body's natural repair processes. Nitric oxide is also involved in normal immune function and acts as an important neurotransmitter within the brain, contributing to cognitive performance and cellular communication.
Supporting the Body's Natural Response to Inflammation
Inflammation is an essential part of the healing process, but when it becomes excessive or prolonged it can interfere with recovery and overall wellbeing.
Emerging research suggests PEMF may help support the body's natural inflammatory response by influencing a number of cellular signalling pathways involved in tissue repair and regeneration. Scientists have also investigated PEMF's interaction with the Nrf2 pathway, an important regulator of the body's own antioxidant defences and cellular resilience.
Activation of these protective mechanisms may help cells better respond to physical stress while supporting normal repair and recovery.
A Technology Designed to Support Natural Function
Rather than forcing biological change, PEMF works with the body's own electrical systems, supporting the cellular processes that occur naturally every second of every day.
This is why PEMF therapy is increasingly used by athletes, health professionals and individuals focused on longevity, recovery and preventative wellness. As research continues to evolve, our understanding of how electromagnetic fields influence human biology continues to grow, making PEMF one of the most exciting areas in modern wellness technology.
At Mind & Body Tech, we believe the most effective wellness technologies are those grounded in science, supported by research, and designed to help your body perform at its best.
Before & After PEMF

Visual Observation Following PEMF Therapy
Reduced Inflammation
These images show a live blood microscopy sample taken immediately before and after a single 20-minute CELLER8 PEMF session.
In this example, taken from a healthy woman in her 50s, the blood analyst observed a reduction in the white, irregular structures visible in the sample following treatment. Within the context of live blood microscopy, these features were interpreted by the analyst as being consistent with reduced inflammatory activity.
While these observations are visually interesting, live blood analysis is not a validated diagnostic tool and should not be used to diagnose or monitor inflammation or disease. Instead, the images are intended to illustrate one example of the physiological changes that some practitioners have reported following PEMF therapy.
The growing body of research into PEMF focuses on measurable biological mechanisms, including its effects on cellular signalling, circulation and inflammatory pathways, which provide a stronger scientific foundation for understanding how PEMF may support recovery and overall wellbeing.

After PEMF
Visual Observation Following PEMF Therapy
Increased Oxygen Levels
These images show a dry blood sample taken immediately before and after a single 20-minute CELLER8 PEMF session.
In this example, taken from a healthy woman in her 50s, the blood analyst observed a noticeable difference in the appearance of the blood sample following treatment. The post-session sample displayed a deeper red colour compared with the pre-session image. Within the context of dry blood analysis, this change was interpreted by the analyst as being consistent with improved oxygenation.
While these images provide an interesting visual comparison, dry blood analysis is not a validated method for measuring blood oxygen levels or diagnosing physiological changes. They should therefore be viewed as observational rather than conclusive evidence.
Scientific research into PEMF has instead focused on measurable biological mechanisms, including its potential effects on circulation, nitric oxide production and tissue perfusion, all of which may support healthy oxygen delivery as part of the body's normal physiological function.

Visual Observation Following PEMF Therapy
Increase White Blood Cell Count
These images show a live blood microscopy sample taken immediately before and after a single 20-minute CELLER8 PEMF session.
In this example, from a healthy woman in her 50s, the blood analyst observed differences in the appearance and movement of white blood cells following the PEMF session. Compared with the initial sample, the post-treatment image appeared to show more active white blood cells moving throughout the field of view.
Within the context of live blood microscopy, these observations were interpreted by the analyst as reflecting increased cellular activity. However, live blood analysis is not a validated method for measuring white blood cell count, immune function or overall health, and these observations should not be considered diagnostic or conclusive evidence of physiological change.
The scientific evidence supporting PEMF is based primarily on laboratory and clinical research investigating its effects on cellular signalling, circulation, inflammation and tissue repair, rather than live blood microscopy observations.

What is PEMF commonly used for?
As mentioned, PEMF therapy creates an optimal environment within the body to support healing and recovery. It can benefit a wide range of conditions, promoting pain relief, reducing inflammation, and encouraging cellular repair. The examples listed below highlight just a few common applications of PEMF therapy, demonstrating its effectiveness across various areas of health and wellness.
Collapsible content
Pain Relief & Recovery
Pain is often accompanied by inflammation, reduced circulation and increased sensitivity within the nervous system. Because PEMF therapy supports several of these underlying physiological processes, it has become an increasingly popular non-invasive option for people looking to improve comfort, mobility and recovery.
Research suggests that PEMF may help reduce pain by supporting healthy circulation, enhancing oxygen and nutrient delivery to tissues, and influencing the body's natural inflammatory response. Many users also report improvements in stiffness, joint function and overall quality of life following regular use.
One randomised controlled clinical trial involving 120 patients with joint and soft tissue pain compared daily PEMF therapy with standard care over a 14-day period. Participants using PEMF experienced a 36% reduction in pain, compared with 10% in the standard care group. They also reduced their use of pain medication by 55%, versus 12% in the control group. When the standard care group later crossed over to PEMF therapy, they experienced additional reductions in both pain and medication use.
While individual results vary and PEMF is not intended to replace medical treatment, these findings add to a growing body of research suggesting that PEMF therapy may provide meaningful support for pain management and recovery when used as part of a broader wellness programme.
PubMed ID:39928254
Supporting a Healthy Inflammatory Response
Inflammation is a vital part of the body's natural healing process. However, when inflammation becomes prolonged or excessive, it can contribute to ongoing pain, stiffness and slower recovery.
One of the most widely researched areas of PEMF therapy is its potential to support the body's normal inflammatory response. Rather than simply masking symptoms, PEMF is thought to influence the cellular signalling pathways involved in regulating inflammation and tissue repair.
Research has shown that PEMF may activate adenosine A2A receptors (A2ARs), which play an important role in helping the body regulate inflammation. Activation of these receptors has been associated with reduced activity of NF-κB, a key signalling pathway involved in the production of pro-inflammatory cytokines. Cytokines are chemical messengers that help coordinate the immune response, but when produced in excess they can contribute to chronic inflammation and tissue damage.
Laboratory studies have demonstrated that specific PEMF frequencies and intensities can influence these biological pathways, reducing the production of pro-inflammatory cytokines while supporting the body's natural repair mechanisms. Researchers are also investigating the role of A2A receptors in protecting nervous tissue and regulating inflammation within the brain, making this an exciting area of ongoing research.
While PEMF is not a treatment for inflammatory disease, growing evidence suggests it may be a valuable complementary therapy for supporting recovery, joint health and overall wellbeing by helping the body maintain a balanced inflammatory response.
Science Direct ID: S1094715921064266
Cellular Repair & Rejuvenation
The human body is constantly repairing and renewing itself. From muscle fibres and connective tissue to bone and cartilage, specialised cells work continuously to maintain healthy tissues and respond to everyday wear, exercise and injury.
PEMF therapy has been widely studied for its ability to support these natural repair processes by influencing cellular activity and communication. Rather than creating new biological processes, PEMF is believed to enhance the conditions that allow cells to function more efficiently.
Research has shown that PEMF may stimulate the activity of chondrocytes, the specialised cells responsible for maintaining and repairing cartilage. Studies have also demonstrated increased production of growth factors, including bone morphogenetic proteins (BMPs), which play an important role in the formation, maintenance and repair of bone and connective tissue.
In addition, PEMF has been shown to influence adenosine A2A and A3 receptors, helping regulate inflammation while supporting healthy blood flow and cellular signalling. Together, these mechanisms may create an environment that encourages tissue repair, recovery and regeneration following physical stress or injury.
While research continues to evolve, the ability of PEMF to support normal cellular function has made it an increasingly popular technology among athletes, health professionals and individuals focused on recovery, healthy ageing and long-term wellbeing.
PubMed ID:29020880
Improve Circulation & Oxygenation
Healthy circulation is fundamental to almost every aspect of human health. Every second, your bloodstream delivers oxygen and nutrients to tissues while removing carbon dioxide and metabolic waste products. Efficient blood flow supports energy production, exercise performance, recovery and the body's natural repair processes.
One of the most widely studied effects of PEMF therapy is its ability to support healthy circulation. Research suggests that PEMF may stimulate the production of nitric oxide (NO), a naturally occurring signalling molecule that helps blood vessels relax and widen. This process, known as vasodilation, allows blood to flow more freely, enhancing the delivery of oxygen and nutrients to cells throughout the body.
Improved circulation may help support tissue repair, muscle recovery and overall cellular function by ensuring that tissues receive the resources they need to perform and recover efficiently.
Preclinical research has demonstrated this effect in action. In one study, researchers investigated the impact of PEMF on the small blood vessels of laboratory rats. After exposure to PEMF, blood vessels expanded by approximately 9%, while no significant changes were observed in the placebo group. Importantly, these improvements occurred without changes in blood pressure, heart rate or tissue temperature, suggesting that PEMF may support local circulation without placing additional stress on the cardiovascular system.
Although research in humans continues to evolve, these findings contribute to a growing body of evidence suggesting that PEMF therapy may help support healthy circulation and oxygen delivery—two essential components of recovery, performance and long-term wellbeing.
PubMed ID:14656663
Supporting Healthy Energy Levels
Every cell in the body depends on a constant supply of energy to function efficiently. Whether you're exercising, recovering from physical activity or simply going about your day, your cells rely on adenosine triphosphate (ATP)—often referred to as the body's energy currency—to power virtually every biological process.
PEMF therapy has been studied for its potential to support healthy cellular energy production. Research suggests that pulsed electromagnetic fields may influence mitochondrial function by supporting the movement of electrons within the electron transport chain, the process responsible for generating ATP. By helping cells produce energy more efficiently, PEMF may support physical performance, recovery and overall vitality.
PEMF has also been shown to influence the production of nitric oxide, a naturally occurring signalling molecule that helps promote healthy circulation. Improved blood flow enhances the delivery of oxygen and nutrients to tissues while assisting with the removal of metabolic waste products, further supporting the body's natural energy systems.
While PEMF is not a substitute for good nutrition, regular exercise or quality sleep, growing research suggests it may help optimise the cellular processes that underpin energy production. For many people, this can contribute to improved recovery, greater resilience and sustained wellbeing throughout the day.
Supporting Restoritive Sleep
Quality sleep is one of the foundations of good health. During sleep, the body repairs tissues, consolidates memories, regulates hormones and restores the energy needed for optimal physical and cognitive performance. When sleep is disrupted, recovery, resilience and overall wellbeing can all be affected.
PEMF therapy has been investigated for its potential to support healthy sleep by helping regulate the body's autonomic nervous system. Research suggests that PEMF may encourage a shift towards the parasympathetic or "rest and digest" state, promoting relaxation and creating the conditions for deeper, more restorative sleep. By supporting the body's natural recovery processes, PEMF may also help reduce some of the physiological stress that can interfere with healthy sleep patterns.
Clinical research has shown encouraging results. In a four-week, randomised, placebo-controlled study conducted at the Universität der Bundeswehr München, 101 participants with insomnia used either an active PEMF device or a placebo. Those receiving active PEMF therapy experienced significantly greater improvements in sleep quality, including falling asleep more quickly, fewer night-time awakenings and reduced daytime fatigue, compared with the placebo group. The treatment was also well tolerated, with no significant adverse effects reported.
While individual responses will vary, improving sleep quality may be one of the most valuable benefits of PEMF therapy. Better sleep supports recovery, cognitive performance, immune function and overall health, creating the optimal environment for the body to repair, regenerate and perform at its best.
PubMed ID:11697020
Promote Recovery
The human body has an extraordinary ability to repair and renew itself. Every day, billions of cells are replaced, damaged tissues are repaired and complex biological systems work continuously to maintain health. These natural processes rely on energy, healthy circulation, balanced inflammation and effective cellular communication.
Rather than targeting a single symptom or condition, PEMF therapy is designed to support the biological processes that underpin recovery. Research suggests that pulsed electromagnetic fields may help optimise cellular function by supporting energy production, promoting healthy circulation, influencing inflammatory pathways and encouraging efficient communication between cells.
Together, these effects may create an environment in which the body's natural repair mechanisms can function more effectively. This is why PEMF has become increasingly popular among athletes, health professionals and individuals focused on recovery, performance, healthy ageing and long-term wellbeing.
While PEMF is not a cure for disease, growing scientific research suggests it can be a valuable complementary wellness technology, helping the body perform as it was designed to—repair, recover and adapt naturally.

1. How to use
For the best results, position the mat or pad so it comfortably covers the area you wish to target, including the surrounding tissues where appropriate. Begin at a comfortable intensity and gradually adjust as you become familiar with the therapy.
During your session, sit or lie in a relaxed position and allow yourself time to unwind. Many users choose to read a book, listen to music or a podcast, meditate, or simply enjoy a period of quiet relaxation.
For optimal results:
- Use the recommended session duration for your device.
- Aim to use your PEMF device consistently, ideally at the same time each day.
- Keep the treatment area and settings as consistent as possible to help monitor your progress over time.
- Stay well hydrated and allow your body time to respond to the therapy.
Like many wellness practices, the benefits of PEMF are often cumulative, with regular use helping to support long-term recovery, performance and overall wellbeing.
-
2. When to use
For most people, 15–30 minute sessions, 3–5 times per week provide an effective starting point. Alternatively, shorter daily sessions of 10–20 minutes can be equally beneficial and are often easier to incorporate into a regular wellness routine.
During periods of increased discomfort or following intense physical activity, shorter, more frequent sessions may be preferable to longer or higher-intensity treatments.
PEMF therapy is most effective when used consistently. Monitor changes in factors such as comfort, mobility, stiffness and recovery over a period of 2–4 weeks, adjusting your routine as needed to suit your individual goals and response.
-
3. Use safely
PEMF therapy is generally well tolerated by most people. However, there are some situations where caution is advised.
- Pregnancy: The safety of PEMF therapy during pregnancy has not been established. Although there is currently no evidence that appropriately used PEMF is harmful during pregnancy, its use is generally not recommended unless advised by a qualified healthcare professional.
- Neurological Conditions: Individuals with epilepsy or other neurological conditions associated with seizures should consult their healthcare provider before using PEMF therapy. Reports of PEMF triggering seizures are extremely rare, but a theoretical risk remains.
- Active Bleeding or Recent Surgery: Because PEMF may support healthy circulation, it should not be used over areas of active bleeding or immediately following surgery until bleeding has been fully controlled and your healthcare professional has confirmed it is appropriate to begin therapy.
If you have an implanted medical device, a serious medical condition, or are receiving ongoing medical treatment, consult your doctor or healthcare professional before starting PEMF therapy.
A Milestone in PEMF: FDA Approval
The development of PEMF therapy was influenced by decades of research into bioelectricity, he electrical signals naturally present within living tissues and their role in biological processes, including growth and repair.
During the 1960s and 1970s, orthopaedic surgeon Dr Andrew Bassett, working alongside Dr Arthur Pilla and other researchers, pioneered the use of pulsed electromagnetic fields to support bone healing. Their work focused particularly on non-union fractures, broken bones that fail to heal successfully through conventional treatment alone.
The researchers explored whether carefully controlled electromagnetic fields could influence the electrical environment associated with natural bone repair. Their clinical research helped establish PEMF as a non-invasive approach for supporting bone healing in difficult cases.
This work represented a major milestone in the development of therapeutic PEMF technology. In 1979, the FDA approved a PEMF-based bone growth stimulator for the treatment of certain established non-union fractures, helping move PEMF from experimental research into recognised clinical use.
Today, PEMF technology continues to be researched across a much broader range of potential applications, but its early development in orthopaedic medicine remains an important part of its scientific foundation.
PEMF STUDIES
PEMF has been the subject of decades of scientific research, with thousands of published studies exploring its effects across a wide range of biological processes and applications. Certain PEMF-based medical devices have also received regulatory approval or clearance for specific clinical uses.
At Mind & Body Tech, we have reviewed a selection of published studies and broken down the key findings into clear, accessible summaries. Wherever possible, we also include the frequency (Hz), intensity (Gauss), and session durationused within each study.
With CELLER8's Custom Mode, users can recreate many of the reported treatment settings used in published PEMF research, with adjustable frequencies and intensities covering the ranges commonly used across many studies. You can replicate nearly all of these studies, as most operate at 1-100 gauss, 1-100 Hz, and run for durations ranging from 5 minutes to 12 hours.

WOUND HEALING
This study explored how low-frequency PEMF may influence processes involved in wound healing. Researchers exposed human dermal fibroblasts, cells that play an important role in skin repair, to PEMF at frequencies of 10–12 Hz and 100 Hz.
At 10–12 Hz, PEMF increased the activity of a gene associated with cell proliferation, while exposure at 100 Hzincreased cell migration and promoted earlier organisation of actin fibres. Both frequencies also supported the development of fibroblasts into myofibroblasts, specialised cells involved in wound contraction and repair.
The findings suggest that PEMF may support several cellular processes involved in wound healing, including cell growth, migration, and maturation. As this research was conducted on human cells in a laboratory setting, further clinical research is needed to understand how these findings translate to wound healing in people.
WHITE BLOOD CELL COUNT
This study investigated how different PEMF frequencies may influence white blood cell (WBC) and lymphocyte (LYM) levels in male mice. The animals were exposed to PEMF at frequencies of 100 Hz, 1,000 Hz, and 10,000 Hz, with an unexposed group used for comparison.
PEMF exposure at 100 Hz and 1,000 Hz was associated with significant increases in both white blood cells and lymphocytes compared with the control group. However, no significant changes were observed at 10,000 Hz.
The findings suggest that the biological response to PEMF may vary depending on the treatment parameters used, with lower frequencies producing different effects from the highest frequency tested in this study. As this research was conducted in mice, the results should not be assumed to produce the same response in humans.
TINNITUS
This double-blind, placebo-controlled trial investigated whether pulsed electromagnetic stimulation could influence symptoms in people with long-standing tinnitus. 58 participants recruited through the Liverpool Tinnitus Association took part, with stimulation applied over the mastoid area behind the ear.
After one week of treatment, participants reported whether their tinnitus had disappeared, improved, remained unchanged, or worsened. Among those who completed the trial, 45% of participants using the active device reported an improvement in their tinnitus symptoms.
The findings suggest that electromagnetic stimulation may have potential for managing tinnitus symptoms in some individuals, although further research is needed to establish its effectiveness and determine optimal treatment protocols.
OSTEOPOROSIS
This study compared the effects of PEMF with alendronate, a medication commonly prescribed for osteoporosis, in 44 women with postmenopausal osteoporosis. Participants were randomly assigned to receive either PEMF or alendronate over a 24-week period.
Researchers assessed changes in bone mineral density at the spine and hip, vitamin D levels, muscle strength, and balance. At the end of the study, no significant differences were observed between the two groups across the measured outcomes.
The findings suggest that PEMF may have potential as a non-pharmacological approach worthy of further investigation in postmenopausal osteoporosis. However, the small study size and relatively short follow-up mean that larger, longer-term trials are needed before its effectiveness can be considered comparable with established osteoporosis treatments.
SLEEP & INSOMNIA
This randomised, placebo-controlled study investigated the effects of PEMF on 101 people experiencing insomnia over a four-week period. Participants received either active PEMF treatment or a placebo device.
Among those receiving active treatment, 70% reported complete or substantial relief, 24% reported clear improvement, and 6% experienced slight improvement. Significant improvements were also reported in time taken to fall asleep, nighttime awakenings, daytime sleepiness, concentration, and headaches.
No adverse effects related to the treatment were reported during the study.
The findings suggest that PEMF may have potential to support sleep quality and reduce symptoms associated with insomnia, although further research is needed to confirm these results and determine the most effective treatment protocols.
NON-UNION FRACTURES
Bone healing is one of the earliest established clinical applications of PEMF. In 1979, the FDA approved a PEMF-based bone growth stimulator for certain non-union fractures, fractures that have failed to heal adequately over time.
In this study, 139 patients with established non-union fractures received PEMF treatment. Treatment success appeared to be strongly associated with daily usage: patients averaging less than three hours per day had a reported success rate of 35.7%, while those averaging more than three hours per day achieved an 80% success rate.
Among patients who used PEMF for more than three hours daily and initially achieved successful healing, long-term follow-up found that 92% maintained solid bone union four years later.
The findings support the established clinical use of specific PEMF bone-growth stimulation devices for difficult-to-heal fractures and also highlight the importance of treatment duration and adherence to prescribed protocols.
MUSCLE ACTIVITY & EXCERCISE PERFORMANCE
This study investigated how PEMF stimulation may influence muscle activity and metabolic responses during exercise. Twenty semi-professional cyclists completed cycling sessions with PEMF either active or inactive in a randomised order.
PEMF applicators were positioned over the vastus medialis and biceps femoris muscles of the right leg. Researchers measured muscle electrical activity using electromyography (EMG), alongside blood lactate levels during exercise.
With PEMF active, researchers observed increased muscle activity during the initial warm-up phase and differences in blood lactate response compared with the control condition. These findings suggest that PEMF may influence neuromuscular activation and muscle metabolism during exercise.
While the results provide an interesting insight into the potential interaction between PEMF and exercising muscle, further research is needed to determine whether these physiological changes translate into meaningful improvements in athletic performance or recovery.
PAIN RELIEF
This prospective, randomised controlled trial investigated PEMF as a non-invasive approach to managing joint and soft tissue pain. A total of 120 participants across five orthopaedic clinics received either daily self-administered PEMF or standard-of-care treatment prescribed by their clinician.
After 14 days, the PEMF group reported an average 36% reduction in pain, compared with 10% in the standard-care group. Reported use of pain-related medication also decreased by 55% in the PEMF group, compared with 12% in the standard-care group.
Participants initially receiving standard care were then offered PEMF for a further 16 days. During this period, they reported an additional 18% reduction in pain and a 63% reduction in medication use.
The findings suggest that PEMF may offer a useful non-pharmacological option for supporting the management of joint and soft tissue pain. However, treatment decisions and changes to prescribed medication should always be discussed with an appropriate healthcare professional.
CANCER RESEARCH & DOXORUBICIN
This 2024 laboratory study investigated whether PEMF could influence the effects of doxorubicin, a chemotherapy drug used in the treatment of several cancers. Researchers studied MDA-MB-231 human breast cancer cells under controlled laboratory conditions.
The cells were treated with doxorubicin and exposed to PEMF for 60 minutes, three times daily, over periods of 24 or 48 hours. The combination of PEMF and doxorubicin was associated with a greater reduction in cancer cell survival than treatment with doxorubicin alone.
Researchers also observed changes in cell-cycle activity and increased markers of DNA damage, suggesting a possible mechanism through which PEMF enhanced the effects of doxorubicin in these cells.
MENSTRUAL PAIN
This study investigated whether PEMF could help reduce pain and menstrual symptoms in 40 women aged 20–30 with primary dysmenorrhoea. Participants were randomly divided into two groups.
The PEMF group received 30-minute sessions three times a week for three months, alongside standard medical treatment, while the control group received standard treatment with NSAIDs alone.
The researchers assessed menstrual distress and pain using a menstrual distress questionnaire and a VAS (visual analog scale) before and after the treatment for both groups. The findings indicated significant improvements in menstrual distress and pain scores for both groups after the treatment, with the PEMF group showing more favourable outcomes. The VAS scores demonstrated a highly statistically significant difference after treatment, favouring the PEMF group. Similarly, the menstrual distress questionnaire results the menstrual distress questionnaire results also reflected a significant reduction in symptoms for the PEMF group compared to the non the PEMF group.

REFRACTORY MIGRAINES
This placebo-controlled study investigated the effects of PEMF therapy in people with refractory migraine, that had not responded adequately to conventional treatments. Participants in the active group received PEMF at 10 Hz and 40–50 Gauss.
After two weeks, the active PEMF group showed significant improvements in headache frequency, headache duration, and hours of work lost compared with the placebo group.
Follow-up assessments of the active group over the following 4–8 months also reported improvements in headache frequency and duration, work-loss hours, and medication use.
The findings suggest that PEMF may have potential as a supportive approach for people with difficult-to-treat migraines, although further larger, controlled clinical studies are needed to confirm these results.

HEADACHES
This double-blind, placebo-controlled study investigated the effects of PEMF on migraine activity in 42 participants who met International Headache Society criteria for migraine.
Participants received either active PEMF or placebo treatment for one hour per day, five days a week, over two weeks, with PEMF applied to the inner thighs.
During the first month of follow-up, 73% of those receiving active PEMF reported a reduction in headache activity, compared with substantially fewer participants in the placebo group. Among the active group, 45% reported a good improvement and 14% an excellent improvement.
Participants who went on to receive an additional two weeks of PEMF treatment also reported further reductions in headache activity.
The findings suggest that PEMF may have potential as a supportive approach for migraine management, although larger clinical studies are needed to confirm the results and determine the most effective treatment protocols.
REDUCED INFLAMMATION
inflammatory conditions are associated with the continued release of pro-inflammatory cytokines, which can contribute to ongoing inflammation and tissue damage.
Research has explored how PEMF may influence these inflammatory pathways. In this study, PEMF at 75 Hz and 15 Gauss was associated with increased expression of A2A and A3 adenosine receptors, which play an important role in regulating inflammatory responses.
The researchers observed that this activity was associated with inhibition of the NF-κB inflammatory signalling pathway and reduced production of certain pro-inflammatory cytokines. These findings suggest a potential mechanism through which PEMF may influence inflammation and help protect tissues.
Researchers have also proposed that these effects on adenosine receptors could have potential relevance to inflammation within the nervous system and neuroprotection, although further research is needed to establish their clinical significance in humans.
REDUCED DOMS
This randomised, double-blind, placebo-controlled study investigated whether PEMF could support recovery from delayed onset muscle soreness (DOMS) following exercise.
Thirty healthy male university students were assessed at 24, 48, and 72 hours after performing exercise designed to induce muscle soreness in the elbow flexors. Researchers measured perceived soreness alongside several indicators of muscle and neuromuscular function.
Compared with the sham treatment, PEMF was associated with improved recovery of perceived muscle soreness and certain measures of muscle function, including median frequency (MDF) and electromechanical delay (EMD). However, no significant difference was found in peak isometric strength.
The findings suggest that PEMF may help reduce some of the symptoms and physiological effects associated with DOMS, supporting its potential use as part of a post-exercise recovery routine.
BREAST CANCER
The currently available anti-cancer therapies, such as gamma radiation and chemotherapeutic agents, induce cell death and cellular senescence (a state in which a cell stops dividing) not only in cancer cells but also in the adjacent normal tissue.
They studied how breast cancer cells (MCF-7 and MDA-MB-231) and normal cells found in connective tissue (fibroblasts - FF95) reacted to PEMFs.
PEMFs were applied at a frequency of 8 Hz, intensity of 110 gauss, using a square wave, and applied twice daily for 5 days.
The data collected showed that the application of PEMF decreases the proliferation rate (how quickly cells multiply or reproduce) and viability (their ability to survive and function normally) of breast cancer cells while having the opposite effect on normal fibroblasts. Additionally, PEMF induces cell death and cellular senescence only in breast cancer cells without any effect on the non-cancerous cells.
BONE HEALTH
This animal study investigated how PEMF may influence bone formation. Over 12 weeks, mice were exposed to PEMF at a frequency of 15 Hz and an intensity of 20 Gauss.
The PEMF-treated mice showed significant improvements in both cancellous bone, the spongy tissue found inside bones, and cortical bone, the dense outer layer. Researchers also observed increased bone formation and mineral deposition, without a corresponding increase in bone resorption.
Gene analysis suggested that these effects may be linked to increased activity within the Wnt/β-catenin signalling pathway, which plays an important role in regulating new bone formation.
The findings suggest that PEMF may stimulate biological processes involved in building and maintaining bone. However, as this was an animal study, further clinical research is needed to determine how these effects translate to bone health in humans.
CIRCULATION
This animal study investigated how PEMF may influence small blood vessels and local circulation. Rats received either active PEMF or a sham treatment for 2 or 60 minutes, with blood vessel diameter measured before and after exposure.
PEMF was associated with significant blood vessel dilation, with vessel diameter increasing by approximately 9% after 2 minutes and 8.7% after 60 minutes. No comparable changes were observed with the sham treatment.
Importantly, the effect occurred without significant changes in blood pressure, heart rate, or tissue temperature, suggesting that the response was local rather than the result of systemic cardiovascular or heating effects.
The findings suggest a potential mechanism through which PEMF may influence local blood flow and processes involved in tissue recovery. However, as this was an animal study, further research is needed to establish how these effects translate to humans.
BRAIN HEALTH & TRAUMA
This preclinical study investigated whether PEMF could influence blood flow and oxygenation within brain tissue, with potential relevance to research into conditions involving reduced cerebral circulation.
Following PEMF exposure, small blood vessels in the brain widened from an average of 26.4 to 29.1 micrometres, while red blood cell movement increased by approximately 5.5%. Researchers also observed changes consistent with improved tissue oxygenation.
When nitric oxide (NO) production was blocked, these effects were no longer observed, suggesting that nitric oxide played an important role in the vascular response to PEMF.
The effects were reported to persist for at least three hours following a 30-minute treatment, highlighting a potential mechanism through which PEMF may influence cerebral circulation. Further research is needed to determine whether these findings translate into clinical benefits for people with stroke, traumatic brain injury, or other neurological conditions.
DEPRESSION
Several clinical studies have investigated transcranial pulsed electromagnetic field stimulation (tPEMF) as a potential approach for depression, including treatment-resistant depression.
In a 2010 double-blind, randomised controlled trial involving 50 patients with treatment-resistant depression, five weeks of tPEMF was associated with significantly greater improvements in depression scores compared with sham treatment.
A separate 2013 randomised, double-blind, sham-controlled trial involving 63 people with unipolar or bipolar depression also reported greater short-term improvements in depression severity following active electromagnetic stimulation compared with sham treatment.
In 2014, a further study followed 65 patients with treatment-resistant depression receiving tPEMF for eight weeks. Depression scores improved significantly, with no meaningful difference observed between participants receiving one or two daily treatment sessions.
Together, these studies suggest that specialised tPEMF may have potential in the treatment of depression and warrant continued clinical research. tPEMF is a specific form of transcranial electromagnetic stimulation and these findings should not be assumed to apply to general-purpose PEMF devices or protocols.
ANGIOGENESIS
This laboratory study investigated how PEMF may influence angiogenesis, the formation of new blood vessels, using human endothelial cells, which play an important role in circulation and tissue repair.
Exposure to PEMF at 80 Hz and a peak intensity of 40 Gauss was associated with increased cell growth and blood vessel-forming activity. Researchers observed changes in how the cells produced energy, including a shift towards glycolysis and changes in mitochondrial activity.
These metabolic changes appeared to support the energy demands associated with endothelial cell growth and angiogenesis, suggesting a potential mechanism through which PEMF may influence processes involved in tissue repair and regeneration.
As this was a laboratory-based cell study, further research is needed to determine how these findings translate to clinical outcomes in people.
ATP
Often described as the powerhouses of the cell, mitochondria play a central role in producing ATP (adenosine triphosphate), the molecule cells use to store and transfer energy.
This study investigated how PEMF may influence ATPase, an enzyme involved in breaking down ATP to release energy for cellular processes. Researchers exposed ATPase to PEMF at 60 Hz, using intensities of 1, 3, and 5 Gauss.
Exposure at 3 and 5 Gauss was associated with increased ATP hydrolysis activity, while 1 Gauss produced no significant change. This suggests that the biological response observed in the study was dependent on magnetic field intensity.
The findings provide insight into one potential mechanism through which PEMF may interact with cellular energy processes. However, they should not be interpreted as evidence that PEMF directly increases whole-body energy levels, and further research is needed to understand the wider biological significance of these effects.
CARTILAGE REPAIR
Research has explored how PEMF may influence chondrocytes, the specialised cells responsible for maintaining and producing cartilage.
Laboratory and preclinical studies suggest that PEMF may support chondrocyte proliferation and activity, including processes involved in the production and organisation of the extracellular matrix that gives cartilage its structure. These effects have also been linked to signalling molecules such as bone morphogenetic proteins (BMPs), which play important roles in the development and maintenance of bone and cartilage.
PEMF has also been studied for its interaction with A2A and A3 adenosine receptors, which are involved in regulating inflammatory responses and tissue protection.
Together, these findings suggest several potential biological mechanisms through which PEMF may support cartilage health and influence inflammatory processes. However, the evidence described includes laboratory and preclinical research, and further clinical studies are needed to establish how these effects translate to outcomes in people.
BACK PAIN
This randomised controlled study investigated whether adding PEMF to conventional physical therapy could provide additional benefits for people with chronic lower back pain.
Fifty participants were divided into two groups. Both received standard physical therapy, while one group also received active PEMF at 50 Hz and 20 Gauss and the other received sham PEMF. Participants completed 12 treatment sessions over four weeks.
The group receiving active PEMF experienced significantly greater improvements in pain, disability, and lower back range of motion compared with the fake therapy group.
The findings suggest that PEMF may provide additional benefits when used alongside conventional physical therapy for chronic lower back pain, although further research is needed to confirm these results across larger and more diverse patient groups.
PTSD
This animal study investigated whether PEMF could influence PTSD-like behaviours and neurogenesis, the formation of new neurons, in rats exposed to a traumatic stress model.
The animals receiving PEMF were treated daily for 14 days, with each session lasting 16 minutes at 30 Hz and 70 Gauss.
Compared with untreated animals exposed to the same stress model, the PEMF-treated rats demonstrated reductions in certain fear- and anxiety-related behaviours alongside increased markers associated with neurogenesis.
The findings showed that these PTSD rats had less fear and anxiety, and improved brain cell growth, compared to those that didn’t receive PEMF. This suggests PEMF might help reduce PTSD symptoms and protect brain health.
RHEUMATOID ARTHRITIS
This study investigated the effects of PEMF on inflammation and joint damage using a collagen-induced arthritis mouse model, commonly used in research to study rheumatoid arthritis. PEMF was tested at frequencies of 10 Hz and 75 Hz.
Treatment at 10 Hz was associated with reduced paw inflammation, cartilage damage, and signs of arthritis. Tissue analysis also showed reduced inflammatory cell infiltration and less damage to cartilage and bone in PEMF-treated mice.
Researchers also observed reductions in several inflammatory markers within the affected joint tissues, suggesting that PEMF may influence local inflammatory processes and help preserve joint structure in this animal model.
Overall, the study suggests that PEMF can help slow RA progression by protecting joint tissues and reducing inflammation, showing promise as a complementary therapy for RA management.
Frequently Asked Questions
Collapsible content
Is PEMF therapy safe?
Pulsed Electromagnetic Field (PEMF) technology has been researched and used for decades across both clinical and wellness settings. When used as directed, PEMF is safe and non-invasive.
PEMF therapy contraindictions
Implanted Electronic Devices: one of the main contraindication’s of PEMF therapy are for individuals who have a pacemaker, cochlear implant or an intrathecal pump fitted. If you have an implanted electrical device such as a pacemaker, cochlear implant or an intrathecal pump we do not recommend you apply PEMF therapy because there is a risk there is a risk that the magnetic field produced by a PEMF device can shut the device off or otherwise interfere with its function.
Organ Transplants: PEMFs are contraindicated in organ transplant patients. PEMF therapy is not advised after an organ transplant as over stimulation could increase the risk of rejection.
PEMF Cautions
Pregnancy: caution is advised during pregnancy. Whilst there is no evidence of harm caused by using PEMFs during pregnancy, their safety has not yet been established.
Neurological Conditions: those with neurological conditions that can cause seizure (e.g epilepsy) are advised to be cautious when using PEMF therapy. Reports of PEMF initiating a seizure are very rare however there is the theoretical potential for this to happen.
Active Bleeding: one of the benefits of applying PEMF therapy is the increase in circulation and blood oxygenation but for people suffering from active bleeding i.e after an operation, this may worsen the blood loss and reduce the ability of the blood to clot in order for it heal over properly. Any source of bleeding should be fully controlled before using PEMF therapy.
Are there any side effects?
Across published PEMF research, no negative side effects have been reported.
In higher-intensity PEMF, 3,000 Gauss and above, side effects are rare but can occur if sessions are run for too long or at excessive intensity. In these cases, some individuals may report temporary muscle soreness as high-intensity PEMF can stimulate muscle tissue in a way that feels similar to light exercise. Occasionally, a short-lived “flu-like” feeling is described, often when intensity and duration are increased too quickly. These effects are typically mild and resolve on their own. As with any wellness technology, starting gradually and following recommended usage guidance helps ensure sessions remain comfortable and well tolerated.
How
How often do I need to use PEMF?
We recommend for the perfect recipe for health and wellness to use the CELLER8 (full body mat if possible) twice per day for the recommended 20 minutes per session. One session in the ‘morning‘ and one session in the ‘evening’ on those program names. You do also have the ability to shorten or lengthen the preset programs and sessions where required if you have more or less time to enjoy some PEMFs.
There are bonus sessions including ‘night’, where you can just use the CELLER8 controller by your pillow to encourage deep and restful slumber and a ‘meditation’ setting, to help find your inner zen whilst also benefitting from the healing benefits of low frequency pulsed electromagnetic fields.
Is PEMF therapy FDA approved for anything?
Yes PEMF has gained any FDA approvals for a wide range of conditions, which are listed below:
1979 – FDA approved PEMF therapy for healing non-union fractures.
1987 – FDA approved for adjunct therapy when treating postoperative edema and pain.
1998 - FDA approved PEMF Therapy for urinary incontinence and muscle stimulation.
2004 - FDA approved PEMF Therapy for cervical fusion patients at high-risk of non-fusion.
2006 - FDA approved PEMF Therapy for treatment of depression and anxiety.
2011 – FDA approved PEMF Therapy for treatment of brain cancer.
Are EMFs & PEMFs the same?
No. A big difference between PEMFs and EMFs is that PEMF therapy uses frequencies and magnetic fields at therapeutic levels. PEMF devices are considered healing because they replicate the natural magnetic field and low frequencies of the earth and never reach the high frequencies or heating effects of EMFs. It is unproven that EMFs (such as from wireless devices) have a negative effect on your health but they are also different from PEMFs.
Is higher intensity safe?
You may come across comparisons suggesting that only low-intensity PEMF devices are "safe", often supported by charts referencing organisations such as the International Commission on Non-Ionizing Radiation Protection (ICNIRP) or the World Health Organization. These charts can create the impression that medium or higher-intensity PEMF systems operate within a "danger zone".
In reality, these exposure guidelines were not developed for therapeutic PEMF devices. They were created to protect the general public and workers from continuous environmental electromagnetic field exposure, such as that produced by power lines, industrial equipment or MRI fringe fields, where exposure may occur across the whole body for extended periods.
Therapeutic PEMF is fundamentally different. It delivers carefully controlled pulsed electromagnetic fields for relatively short treatment sessions and is typically applied to a specific area of the body rather than continuously to the whole body.
For this reason, environmental exposure limits cannot be directly compared with therapeutic PEMF dosing. In fact, decades of clinical and laboratory research have investigated a wide range of PEMF intensities, including many higher than those shown on simplified comparison charts, without identifying significant safety concerns when devices are used appropriately and according to the manufacturer's instructions.
As with any wellness technology, the effectiveness of PEMF depends on selecting the appropriate field strength, frequency and treatment duration for the intended application, rather than assuming that lower intensity is always better or inherently safer.
What is the difference between high and low intensities?
PEMF devices vary in field strength, which is typically measured in Gauss (G). While higher intensity may sound more powerful, effectiveness depends on matching the right intensity to the intended purpose—not simply using the strongest magnetic field available.
Low Intensity (<10 Gauss)
Low-intensity PEMF devices produce gentle magnetic fields that are well suited to regular, restorative use. They are often chosen by sensitive individuals or those seeking a gradual approach to supporting recovery and overall wellbeing. Consistent use over time may help support normal cellular function and relaxation.
Medium Intensity (10–100 Gauss)
Medium-intensity PEMF is widely used in both research and clinical practice and is often considered the most versatile range for everyday wellness. It provides a balance between comfort and biological stimulation, making it suitable for supporting recovery, healthy inflammatory responses, circulation and cellular function. M
What is slew rate?
Slew rate describes how quickly the magnetic field changes during each pulse. In simple terms, it measures the speed at which the magnetic field rises to its peak and then falls again. Two PEMF devices can produce the same peak intensity, yet behave very differently depending on how rapidly they reach that peak.
A waveform with a high slew rate rises to its maximum intensity almost instantly, creating a steep, rapid change in the magnetic field. According to the principles of electromagnetic induction, faster changes in the magnetic field generate stronger electrical currents within the body's tissues. This is one of the reasons why slew rate is considered an important performance characteristic of a PEMF device.
By comparison, a waveform with a low slew rate takes longer to reach its peak intensity. Although it may achieve the same maximum Gauss, the more gradual rise produces a weaker rate of change, resulting in a lower induced electrical current.
This illustrates why peak intensity alone does not determine the effectiveness of a PEMF device. The body's response depends on a combination of factors, including intensity, frequency, waveform and slew rate, all working together to influence how electromagnetic energy is delivered to the tissues.
