Safety of PEMF devices

Safety of PEMF devices - Neopemf 3

PEMF is most commonly associated with giant, vibrating pads that are able to stimulate and speed up the healing of muscles, fractures and tears. Those machines are expensive to purchase for home use, and sometimes costly to visit even at a practitioner’s office. But ever since PEMF has become more versatile in its use and expanded into many households, certain health risk concerns arose, particularly aiming at the PEMF devices aimed at the brain.

Brainwave entrainment is a method of synchronizing brain waves from an external stimulus. Brainwave entrainment in practice is nothing new, as the architectural deconstruction of some ceremonial chambers of the Bronze Age suggest they have been acoustically tuned to trigger specific brainwave frequencies, as well as the simple machines of ancient Greeks triggering the photic way of entraining their brain by using a spinning wheel pointing to the sun and producing flickering light, resulting in an altered state of being. However long have people succumbed to photic and auditory ways to induce new altered states, it has only been scientifically researched for a good 80 years. Today, brainwave entrainment is most commonly found in meditation sounds and binaural beats recordings, where the audio can serve as the outside stimuli, and the brain adapts to the newly introduced frequency by slipping into deeper brainwaves, such as Theta.

However, there is a great deal of scientific research that proves the electromagnetic frequencies do exactly the same. The goal of a PEMF system is to produce the magnetic field that is recognized and supported by one’s body. Although everything around us can be measured in frequencies, it is important to understand that not all frequencies are beneficial for us. The harmful EMFs such as X-rays or Gamma waves have a significantly shorter wavelength and can harm your body significantly when exposed to them, whereas the therapeutic magnetic fields require very long wavelength and low intensity frequencies. The Earth itself has a frequency of 7.8 Hz and the consumer microwave oven’s general frequency of 2.45 GHz. Both of them have relatively long wavelengths with low frequencies and neither of them are harmful.

There are many PEMF systems that range up to 200kHZ+ and are scientifically proven to be entirely safe. Some PEMF devices for home use are used to stimulate the entire body and can range from 1000 to 30.000 Gauss or more, such as A Pulsed Harmonix or Zimmer Emfield Plus. Although those machines can use targeted applications of the PEMS, the brain is still more often than not in the range of receiving the pulses as well.

But for the PEMF system to have any effect, it must pass through the body, and if the cells are not in need of a recharge, it will neither harm nor benefit them. For hard tissue cell repair, such as fractures or sprains, PEMF has to be applied on the closest part of the injury as possible (skin) and use high enough intensity to be able to penetrate through the tissue. But although PEMFs are infinite, their effect isn’t. The intensity is the highest right next to the coil, but drops with the inverse-square law – meaning that if you are using a device generating a 25 Gauss magnetic field and move it 1 cm away from the spot of treatment, it will drop down to 5 Gauss intensity.

A study concluded in 2019 by two psychiatrists observing the use of transcranial magnetic stimulation for depression, has shown results in great effect for treating depressive mood symptoms, with remission rates of 30% to 40% of cases. They used a TMS machine with an intensity of 1.5 Tesla which is comparable to the intensity of an MRI machine. The use of PEMF has been irreplaceable in the field of treating clinical depression for people who are unresponsive to medicine.

However, there aren’t any remarkable scientific studies alluding to any permanent or instant damage of using PEMF on the body or brain. Even the patients using high intensity devices to treat their depression a few times a week showed no significant negative side effects. The most negative effects reported by patients were either highly energized, jittery state or feeling lack of energy or mental fog. Slowing down with the treatment and ensuring plenty of hydration usually resolves most of those side effects.

In addition, PEMF systems are wellness devices. They do not work like medication – a magnetic field does not affect the chemical part of your brain or body. The magnetic field acts on a cellular level and recharges the cells, rather than impacting them chemically. The recharge of hard tissue cells was initially observed by veterinarians, using PEMF to treat horses with a fractured leg. In 1979 the FDA approved PEMF therapy for stimulating bone growth and in 1987 for adjunct therapy for treating postoperative edema and pain. In 2004, PEMF was used as an adjunct to cervical fusion surgery, in 2008 approved for treatment in depression for patients unresponsive to medication and in 2011 the FDA approved PEMF Therapy for treatment of brain cancer.

Using PEMF in your everyday life is therefore no more harmful than using your cellphone, heating up a meal or shopping online. PEMF devices are remarkably valuable for use in modern medicine and are an effective alternative treatment for people who are unresponsive to the medicine treating the chemical components of the brain.
