Low-Intensity PEMF

PEMF devices that work at lower field strengths, from a few microtesla (µT) up to about 1,000 Gauss. Lower strength doesn't mean weaker effect. Much of the published PEMF research operates right in this range, because the body responds to the pulse frequency and the specific field strength, not to raw peak power. Researchers have even mapped "biological windows," specific amplitude bands where an effect appears; above the window it can fade or reverse, so more Gauss isn't automatically more benefit. These lower strengths also hold the oldest documented applications, including bone-growth stimulators the FDA has cleared since 1979. Low-intensity systems suit surface and near-surface target areas and everyday wellness like recovery, circulation, relaxation, and sleep, while high-intensity systems exist for deeper reach. Field strength runs from the microtesla range up to 1,000 G (about 100 mT); above that is generally classed as high-intensity.
