To understand why PEMF can influence the body, it is important to understand that the body itself is electrical in nature.
Every second of every day, your body relies on electrical signals to function. Nerves communicate through electrical impulses, muscles contract using electrical activity, and even your heartbeat is controlled by electrical signals. In fact, many of the medical tests we use today, such as ECGs and EEGs, work by measuring the body's natural electrical activity.
At an even smaller scale, every cell in the body maintains an electrical charge across its membrane, often referred to as the membrane potential. This electrical charge helps regulate how cells communicate, transport nutrients, produce energy, and perform their specialised functions.
Because the body already uses electricity as a fundamental part of its operation, it can respond to the tiny electrical currents induced by PEMF therapy. Rather than introducing a drug or chemical into the body, PEMF works by interacting with processes that already exist naturally.
This is why many researchers believe the biological effects of PEMF begin at the cellular level, where these induced electrical currents can influence cellular communication, signalling pathways, and energy production.
