In a recent newsletter, the South African NGO EMFSA (Electromagnetic Fields South Africa) highlights a Swiss Federal Office of Public Health fact sheet warning that some mains-powered magnetic field mats can exceed recommended exposure limits and that long-term health risks cannot be ruled out.
"The strong magnetic fields generated by these mats may, in some cases, exceed internationally recommended limit values. Consequently, potential health risks from long-term use cannot be ruled out."

"One precaution highlighted is that children and pregnant women should avoid using magnetic field mats."
