Electric and magnetic fields (EMFs) are found everywhere electricity is used and come from home appliances, computers, office equipment, wiring in our homes and workplaces, and electric power facilities such as substations and transmission or distribution lines.
For more than 30 years, research studies have examined questions around EMFs and health. Health agencies and a large number of reputable scientific organizations around the world have concluded that the scientific research does not demonstrate that EMFs cause or contribute to adverse health effects. Some scientific questions remain the subject of ongoing research.
