What are the differences between PEMF & Harmful EMF’s?

A common cause of confusion regarding Pulsed Electromagnetic Field (PEMF) therapy is that it is associated with the harmful Electromagnetic Fields (EMFs) that are present within the environment. However, the pulsed electromagnetic fields differ from the harmful electromagnetic fields in several ways. Continue reading for more information on the main differences between PEMF and EMFs.

Magnetic frequencies help to regulate several processes of the human body. In fact, our bodies even produce their own magnetic fields. However, when artificial and harmful electromagnetic fields enter your body, such as those from cell phone service or power lines, they can disrupt the way your body naturally works, creating an imbalance. This can cause changes to any of the natural systems within your body, from your stress levels to your sleep cycles, to your DNA. This imbalance may also make your body more susceptible to disease.

Alternatively, one of the good magnetic fields known as, pulsed electromagnetic fields, contribute to the healing and improvement of the health of both humans and animals. PEMF is a technology that has been used internationally for several decades to help to reverse those imbalances caused by harmful electromagnetic fields by delivering beneficial frequencies to your body. It accomplishes this by sending a pulsing electromagnetic field that stimulates and energizes the cells within your body. Your body takes this energy and then uses it for its natural self-healing functions.

Beyond the effects of these electromagnetic fields on your body, the differentiating factors, or what actually makes one frequency harmful, and the other beneficial are the exposure time, the wavelength, and the frequency. Harmful electromagnetic fields have been recognized in various research studies to have significantly higher frequencies and lower wavelengths than therapeutic PEMFs. Most PEMF devices use low frequencies and long wavelengths, ranging from 1 to 10,000 Hertz, and do not produce any heating action. In comparison, a microwave, which produces harmful EMFs can use frequencies in the range of 100,000,000 Hertz.


The frequency range of therapeutic PEMF devices when compared to power grids can be a cause of concern or confusion for many persons. Although some power grids use what appears to be PEMF level frequencies, which is between 50 to 60 Hertz , it should be noted that this source is regularly polluted with surges of dirty electricity. As a result, the power grids actually contain frequencies significantly higher than the 50 to 60 Hertz frequencies that were intended. Fortunately, PEMF devices contain several layers of filtering to remove surges that come from the household electrical outlets used to power the device.

One of the greatest concerns about EMFs is at it relates to continued exposure. It is not about the one-time use of a microwave, or an hour or two on a cellular device, but from round the clock interaction with these household devices. The amount of EMF exposure from household appliances such as heaters, hair dryers, electric shavers, televisions and other electrical devices can negatively impact your health over a period of time. Exposure to what we call “ordinary” household appliances and electronics can create a much greater cumulative EMF exposure than the power grid.

Research has shown that pulsed electromagnetic fields in low frequency and intensity can result in an increase of oxygenation to the blood, improve the body’s circulation and enhance cell metabolism. Results of PEMF therapy includes a better sleep cycle, pain relief, reduced inflammation, and improved energy levels, among many others.
