Many people suffer discomfort after working long hours on the computer. This is in part due to the fact that computers produce an Electro-Magnetic Field (EMF radiation) which is considered to be harmful to the human body’s own electrical field. Over the past few years the popular press has increased public awareness of this concern, so nowadays there is increased interest in the effects upon health of EMF exposure. It is widely accepted that constant exposure to the kind of radiation emitted by computers leaves us feeling drained and fatigued.
