The movement of electrically charged ions in and out of cells is the main source of the body's electrical and magnetic fields. The generation and maintenance of these bioelectromagnetic fields are also one of the main energy- using metabolic processes occurring the body. Many complementary treatments are based on the theory that the body's energy flows through channels known as meridians. These can be compared with the currents that exist in a magnetic field. In health, energy flows through the meridians in a balanced way.
Ill health is thought to be associated with imbalances or blockages in energy flow through the body.
Transport of ions across cell membranes is altered during inflammation. Electrical transmission through nerves is increased when pain is perceived. Damaged cells may leak potassium ions, producing a slow, steady electric current of as much as 50 millivolts. Sudden electric fluxes occur when a cell dies and releases a burst of potassium ions. Changes in the composition of blood, body fluids and salt balance will alter the body's normal electromagnetic field.
