What is PEMF

Updated: Mar 27, 2023

Pulsed Electromagnet Field Therapy: Our deep dive into its known Benefits

What is PEMF?

Pulsed Electromagnetic Field Therapy (PEMF), also known as low field magnetic stimulation, is a treatment during which an electrical current runs through a copper coil in a device to create a pulsing magnetic field called Pulsed Electromagnetic Fields, or PEMFs, in damaged parts of the body. These PEMFs are said to be able to stimulate healing naturally within the cells of the body, aiding in the prevention of diseases, alleviation of pain and other issues, and the balancing of bodily functions.

What are the benefits?

The benefits of PEMF are believed to be numerous, including:

Pain and inflammation relief

Stimulation of the ANS system

Oxygenation of the tissues and blood

Rejuvenated energy and improved circulation

Headaches and migraines

Blood pressure and cholesterol regulation

Increased nutrient uptake

Increased/improved cell regeneration

Cellular detoxification

Bone and soft tissue repair

Muscle relaxation

Reduced swelling

Improved sleep

Boosting of immunity

Rebuilding of joint cartilage

Clearing of the chakra energy system

Let’s take a look at some of the benefits in detail and delve into the studies that support them:

The Automatic Nervous System

One primary benefit of PEMF is the stimulation of the Automatic Nervous System, or ANS. The ANS is a highly essential part of our nervous system and brain which controls vital functions like breathing, digestion, heart rate, and more. By stimulating the ANS system, PEMF supports the body’s vital function and helps the whole body to sustain itself. (Grote, Lackner, Kelz, et al., 2007).

For Headaches and Migraines

Migraines are extremely painful headaches, frequently leading to nausea, sensitivity to light and sounds, and often rendering sufferers unable to get out of bed until they’re alleviated. (Asghar, Hansen, Kaijimpanga, et al., 2010). According to some studies we found, migraines are associated with an irregular blood flow within the brain. (Shevel, 2011). Others include causes of hormonal, emotional, or physiological changes, like fluctuations in blood pressure. (Wang, Timsit-Berthier & Schoenen, 1996). Since PEMF is known to dilate blood vessels in the brain, as well as improving the circulation in the body, it has become a valuable treatment for migraines, targeting many of these issues. (Mix, Jenssen, Lehmitz, et al., 1990).

One related study included one-hour PEMF sessions given five days per week for two weeks to migraine sufferers who were asked to log their headaches afterward. 73% of the participants who received the PEMF sessions logged fewer migraines following the study, revealing that the improved blood circulation to the brain alleviated them and improved cognitive activity. (Sherman, Acosts & Robson, 1999). Another study proved the strong hormone balancing abilities of PEMF therapy, also confirming its appropriateness for daily treatments. (Shupak, Prato & Thomas, 2003).

To Help Improve Sleep

Stress, pain, and illness may all contribute to sleeplessness, eventually causing metabolic issues, hormonal problems, premature aging, and pre-diabetic symptoms. PEMF has become known as a great way to remedy these issues without the need for drugs.

One source we explored explained that PEMF helped to improve sleep for insomnia sufferers by “re-tuning the brain for maximum efficiency,” and followed up with, “Pulsed electromagnetic field therapy works for better sleep by a process known as brainwave entrainment. By stimulating the brain with low frequency PEMF therapy devices, the brain starts locking into the signal that mimics deep sleep state.”

Evidence for the efficacy of PEMF for sleeplessness and other sleep issues can be confirmed in two related studies we discovered. One revealed that repeated PEMF sessions alleviated chronic insomnia, (Jiang, Zhang, Yue, et al., 2013), while the other showed 90% of participants in a 2001 double-blind study found relief in 4 weeks when PEMF was given while 75% experienced complete reversal of the problem. (Pelka, Jaenicke & Gruenwald, 2001).

In conclusion

Today we’ve made a hardy beginning in our exploration of Pulsed Electromagnetic Field therapy, and we can see the claims to its benefits are grounded solidly in the research. Since it’s been around for a while, there are many known/believed benefits, and today we’ve confirmed its efficacy for stimulating the ANS system, alleviating headaches and migraines, and helping with insomnia. When we update our PEMF info, we’ll delve into some of the other numerous benefits it’s believed to possess.
