PEMF builds up energy within the cells, oxygenates the cells, alkalizes the cells, improves the cells and improves circulation so nutrients, oxygen etc goes in and the waste is processed out. PEMFs are like a spark plug or catalyst for energy production in the cell. Just like a car needs oxygen, fuel and a ignition (spark plug), so does the human cell need fuel (glucose), oxygen and a spark plug or ignition.
This ignition is PEMF or pulsed magnetic energy from both the earth and movement/exercise on the earth. Pulsed electromagnetic fields act like a catalyst and are critical for human metabolism (Some countries in the Far East refer to Chronic Fatigue and Fibromyalgia as "Magnetic Deficiency Syndrome".)
Also because PEMF stimulates the production of stored energy across the cell membrane, it helps to enhance the function of the Sodium-Potassium Pump. This helps to increase oxygenation, hydration and nutrient absorption by 200%! AND, it helps the cells to remove waste.
Studies with the Russian Space Program, NASA and Zero Field Studies on earth have PROVED BEYOND A SHADOW OF A DOUBT that in just a matter of hours of NO exposure to healthy PEMFs, cell metabolism begins to break down causing bone loss, muscle weakness, depressed metabolism, disorientation and depression. Since the VERY FIRST space launch, PEMF generators have been used in spacesuits and spacestations.
