It is so simple, the EarthPulse magnetic inductor is placed under your mattress, turn the main unit on, choose the sleep program of your choice, set the timer and click it on. You will be sleeping in gentle, totally natural, healthy, regenerating, pulsed magnetic fields all night long. Our all-night pulsed magnetic signal entrains the brain toward deeper sleep, simultaneously stimulating (turbo-charging) mitochondria over long duration nightly sessions that promote more energy production from the same oxygen intake with less oxidative waste. This results in an enhanced night-time recovery, hormone production, memory consolidation, immune function and daytime performance. When used regularly our sleep-machine's patented, low frequency, low-amplitude pulsed magnetic field makes Sleep on CommandTM the world's only sleep, recovery, performance enhancement / ergogenic aid & longevity system. Since mitochondrial dysfunction and oxidative stress are at root of nearly every degenerative disease state (including aging), EarthPulse may be the closest thing to a panacea that has ever existed; because it precisely affects this mitochondrial based issue. The EarthPulse offers you the most convenient way to use pulsed electromagnetic fields, which is  while you are already sleeping (enhancing the experience of sleep) to help promote natural healing mechanisms in perfect circadian rhythm. We use 9.6 Hz in our EarthPulse sleep-machine because it is naturally occurring and explains why 10 Hz stimulation works the way it does. Bob Beck discovered this 9.6 Hz resonation way back in the 70's. 9.6 Hz resonates from the core of mother Earth and we find it helps promote deep sleep through the process known as ENTRAINMENT. It produces remarkable athletic performance enhancement as well.
