Electromagnetic pollution is a complex issue. In most cases it requests the installation of demand switches (they are placed in the fuse box and disconnect the power while no electricity is needed, cutting out any electric fields). Give up on water beds, electric blankets and clock radios can make a difference to your sleep and well-being. Call your local Feng Shui Consultant, Building Biologist or purchase instruments that are available to help you measure your exposure and the effectiveness of your countermeasures.
I also recommend caution with magnetic blankets, pillows, etc. Even though they appear to help people suffering from chronic pain, they are highly magnetised and place a stress on the system. Only recommended as a therapeutic device. None of the manufacturers has done long-term research to prove that their product is safe from side effects.
