What is the significance of electromagnetic fields?
Magnetic fields occur naturally and living cells depend upon them to assist in the maintenance of membrane potential. The earth and sun create a magnetic field. Human movement creates a magnetic field that stimulates body cells, hence the importance of exercise in health maintenance. Without the biomagnetic fields from the earth and sunlight, life would not be possible. Most important is that human movement generates a magnetic field, which brings about cell regeneration. This maintains the membrane potential at the ideal 70 to 90 mV levels.
