How Does PEMF Therapy Work? The Science Made Easy

Pulsed Electromagnetic Field (PEMF) therapy may seem like a daunting concept, and I don’t blame you!

I have a background in magnetic resonance imaging and am not stranger to the world of electromagnetism.

Despite this, it took awhile for me to flesh out the nuances of this technology! I’m my opinion, it is well worth it as it comes with some surprising benefits. 

So, what can it do?  

This technology, also referred to as Low Field Magnetic Stimulation (LMFS) uses magnetic fields to stimulate and enhance the body’s natural healing processes.

This includes being acknowledged by the FDA.

So how does PEMF therapy work? In this blog post, we will look at the science behind it, the benefits, and more.

The Science Behind PEMF Therapy

PEMF therapy is grounded in the science of bio electromagnetics, a field that studies how electromagnetic fields interact with biological entities.

 Every cell within our bodies possesses an electric charge that aids in performing various functions. This includes nutrient absorption, waste expulsion, and communication with other cells.

PEMF therapy seeks to optimize these functions through the application of pulsed electromagnetic fields.

At the most basic level, the therapy employs electromagnetic waves, which are forms of energy that move through space. These waves, just like light or heat, are everywhere around us. PEMF therapy harnesses these electromagnetic waves but modulates them into specific frequencies and intensities that can beneficially interact with our bodies’ cells.

This effect on our bodies is not a foreign concept. In fact, the Earth’s own magnetic field plays a critical role in our wellbeing.

It’s the reason why astronauts are exposed to artificial magnetic fields when in space, to compensate for the lack of Earth’s magnetic field.

But, don’t worry, you don’t have to be launched into the thermosphere to get your hands on this technology. 

PEMF therapy mimics and amplifies these beneficial electromagnetic fields to enhance our body’s normal functioning. The exact frequencies, intensities, and waveforms used in PEMF therapy can vary greatly. Some mimic the Earth’s natural frequencies, while others are selected based on research findings.

In the following sections, we’ll dive deeper into how these variations affect the therapy’s effectiveness.

But the key takeaway here is that PEMF therapy is grounded in solid science, using natural electromagnetic principles to promote health and healing.

How Exactly Does It PEMF Therapy Work? 

The mechanism of PEMF therapy relies on the interaction between the pulsed magnetic fields and the cells in our bodies. This interaction stimulates the cells in a way that promotes their normal functions, leading to various health benefits.

Let’s break it down.

In PEMF therapy, a device generates electromagnetic fields, which are then pulsed at different frequencies and intensities. This is where the term ‘pulsed’ comes from in PEMF. The pulsing action allows the magnetic field to penetrate the body more deeply and effectively than a constant magnetic field would. So fridge magnets won’t have the same effect, try as you may!

In simple terms these pulses “charge” our cells, similar to how a battery might be charged. This helps to optimize their function and is particularly beneficial for cells that may not be functioning optimally due to illness or injury.

One important factor here is the frequency of the pulses, measured in Hertz (Hz). Some PEMF devices are designed to emit frequencies that are similar to those of the Earth’s magnetic field. These frequencies are often in the extremely low frequency (ELF) range (1-300Hz according to OSHA) and are believed to be beneficial to human health.

Another important aspect is the intensity (measured in Gauss, G) of the magnetic field. Different PEMF products can have a range of intensities. 

For instance:

• High Intensity PEMF (1000+ Gauss): Involves stronger magnetic fields and deeper tissue penetration, suitable for targeting specific areas and promoting cellular repair and regeneration. This can provide more targeted therapeutic benefits and accelerate the healing in specific areas. 

•  Low Intensity PEMF (Less than 1000 Gauss) : Utilizes milder magnetic fields, better suited for overall body treatment, relaxation, and enhancing general well-being. This can provide overall systemic effects, such as improving cell function, and reducing overall pain and inflammation.

It’s also worth noting, there are different types of waveforms, which refer to the shape of  wave. Different waveforms may have different effects on the body. For instance, sine and square waveforms of electromagnetic fields (EMFs) can have different effects on the body due to their distinct shapes.

• Sine waveforms, being smooth and continuous, closely resemble natural frequencies found in the environment, and they are generally considered to be more biologically compatible.

•  Square waveforms consist of abrupt changes between high and low states, leading to sharper transitions and higher harmonics. Square waveforms may have a more disruptive impact on the body’s bioelectric processes, potentially causing more interference and discomfort for some individuals.

In summary, the mechanism of PEMF involves generating pulsed magnetic fields that charge up our cells, potentially leading to improved cell function and health. The specific effects can vary based on the frequency, intensity, and waveform of the magnetic field, all of which are usually adjustable.

PEMF and Cellular Function

Each cell in our body has a membrane that serves as a protective wall, regulating what comes in and goes out. This membrane maintains an electrical charge, which is crucial for the cell’s function. However, this charge can diminish due to various factors, such as stress, illness, or injury.

 The pulsed magnetic fields generated by PEMF devices are absorbed by the cells, effectively “recharging” them. This can improve the membrane’s permeability, meaning that nutrients and oxygen can more easily enter the cell, and waste products can more readily be expelled.

Moreover, the improved charge can enhance communication between cells, which is vital for overall bodily functions. By aiding in maintaining optimal cellular function, PEMF therapy can help to support the body’s natural healing and repair processes.

 “The mitochondria is the powerhouse of the cell”. This is the one thing we all remember from biology class and love to recite at parties to prove we are smart.

Well, when exposed to PEMF, these little energy factories can get a nice boost!

The therapy helps enhance the flow of ions and nutrients across the cell membrane, which leads to increased ATP (energy) production in the mitochondria. . So, PEMF therapy is like a mini workout session for our cells, giving them the extra oomph they need to function at their best! This extra oomph can translate into more energy throughout your day! 

I think we all could use a little of that!

 

Healing With PEMF

When our bodies encounter injury or illness, natural healing processes kick into gear, like inflammation. However, these mechanisms can sometimes be slow or inefficient, leading to prolonged recovery times or lingering symptoms. PEMF therapy can act as a catalyst in this process, potentially speeding up recovery and reducing discomfort.

The enhanced cellular function brought about by PEMF therapy can promote quicker tissue repair and more efficient cell regeneration. This is mostly due to the more efficient exchange of nutrients and waste at the cellular level as we talked about above.

However, it could also be due to the effects of PEMF on genes that influence inflammation. PEMF therapy demonstrated the ability to reverse inflammatory activity in human cells, as shown in a compelling study.

By stimulating pro-inflammatory genes and observing their response to PEMF treatment, researchers inferred that the therapy may influence the expression of these genes, potentially turning them off. This drug-free approach could have significant applications in treating inflammation, though further research is needed to fully understand the mechanism. 

The Benefits of PEMF Therapy

PEMF can have a variety of benefits, some we have discussed above, and some are rather surprising!

Based on the interaction of PEMF with our cells and its potential to speed up the healing process, a variety of benefits can arise from this therapy. Some of these potential benefits include improved circulation, reduced inflammation, quicker tissue repair, pain relief, and enhanced bone healing.

There are so many different things we can do to help us sleep better, and as it turns out, PEMF is one of them! A study showed that PEMF helped improve the quality and quantity of sleep in patients suffering from insomnia. 

Research has also indicated potential benefits in dealing with chronic conditions like arthritis, fibromyalgia, and osteoporosis. 

PEMF in Practice

These devices typically transmit the PEMF waves  which using pads or mats. There are a variety of machines available and depends on what exactly you are looking for.

For instance:

•  If you are an athlete recovering from a sports injury, a higher intensity machine with pads or coils may be useful to spot treat the injured area.
• If you are looking for more whole-body benefits, such as better sleep, you may look into getting a whole body mat that is lower intensity.
• If you are looking for pain relief on the go, some of these devices come in small portable configurations. 

Things to consider when looking to choose a device:

• Most devices allow for adjustment of different parameters  based on the individual’s needs.
• All devices need a power source which can come in the form of a plug-in, or batteries (disposable and rechargeable). 
• All devices will have pads, mats, or coils that will need to be quite close to your body. This is something to keep in mind if you are in the market for a portable device. 
• Treatment sessions can last anywhere from a few minutes to an hour. Most people find the sessions to be quite relaxing, especially with the whole body mats. 
• Higher intensity machines may result in some feelings of vibration as well as a warming sensations. 

 

Potential Side Effects and Contraindications

While PEMF therapy is generally considered safe, there are a few potential side effects and contraindications to keep in mind. Some people may experience temporary discomfort, such as mild nausea or dizziness. These side effects are usually short-lived and subside as the body adjusts to the therapy.

Certain groups, such as pregnant women, individuals with electronic implants like pacemakers, and people with certain health conditions, should avoid PEMF therapy unless under the guidance of a medical professional. It’s always advisable to consult with a healthcare provider before starting any new form of therapy.
