Sport injuries such as sprained, strained or torn muscles It is not widely realised that the body generates its own bioelectromagnetic field. The membrane surrounding each cell contains microscopic pores through which ions can flow into or out of each cell. One of the most important pumps is the sodium-potassium pump. Sodium is the main positively charged ion found in the extracellular fluid. The sodium-potassium pump forces sodium out of body cells in exchange for a potassium ion which is forced inside the cells against its concentration gradient.
Potassium is therefore the main positively charged ion present in the intracellular fluid.
The sodium-potassium pump transports three positively charged sodium ions out of a cell in exchange for two positively charged potassium ions. Whenever an electric current flows or an electric field changes, it creates a magnetic field. 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.
