EMF\nEMF stands for Electromagnetic Field, one of the four fundamental forces of our universe. All electrically powered devices emit some electromagnetic radiation. Our homes contain wires carrying 120V (US) current to supply our electrical appliances and even these wires emit some EMF radiation. Near infrared lamp saunas only have wiring on the lamp panel and the lamps themselves emit virtually NO dangerous EMF. In contrast far infrared emitters, emitting frequencies similar to cell phones in the 4-15 micron range maybe quite harmful. The safe limit for sauna EMF dose has been 3 milliGauss (mG). Some agencies are recommending a safe limit of 1mG. Many far infrared emitters far exceed this level.
