Where do electromagnetic fields occur in our natural environment?
Magnetic fields occur naturally, and living cells depend upon them to assist in the maintenance of cellular membrane resilience. The earth and sun create magnetic fields. Without magnetic fields from the earth and sunlight, life would not be possible. Human movement creates magnetic fields within the body that stimulate cells, hence the importance of exercise in health maintenance. Most important, human movement generates a magnetic field, which brings about cell regeneration. This maintains the membrane potential at the ideal 70 to 90 mV level.
