How to Decrease EMF Exposure while Sleeping
First, begin with a visual inspection of your bedroom to identify sources of electric- and/or magnetic fields. Vickie recommends sleeping with your head away from the wall, facing the center of the room—even if it means lying with your head facing the headboard end of your bed.
Why?
Because unless you live in a community that requires buildings to have shielded conduits, you will be exposed to electrical fields from the wiring in your walls. There are not many communities that require this however. Outside of Chicago, where I live, the building code does require electrical wires to be run through a shielded pipe, which reduces both fire hazard and electric field radiation. However, single family homes in most areas of the US have bare wires running through the walls.
If you're not sure whether your wiring is shielded or not, you can purchase a volt sensor from your local hardware store. Just run it up and down across your wall, and if the meter detects an electric field, you know you're being exposed.
Remediating open wiring in a home that's already built can be an expensive venture. The least expensive fix, should your bedroom walls emit electric fields, is to simply turn off the particular circuit breaker for your bedroom at night.
Be aware that just turning your lights off does NOT eliminate electric fields, because the electrical outlets always carry voltage, whether the light is on or off. Next, make sure everything around your bed is battery powered.
