EMF Tips

A dimmer works by passing only part of each AC cycle, which can add noise to the wiring. A standard switch removes that source; health effects are unproven.

Filters target noise on the wiring, which is measurable, rather than any proven health problem. Reviews find weak support for harm, so it is a choice.

Dirty electricity is high-frequency noise on home wiring, which a regular EMF meter cannot see. A meter plugged into an outlet can measure it.

Some LED and CFL bulbs add high-frequency noise to household wiring. Incandescent bulbs in the bedroom avoid that, though health effects of it are unproven.

Evening screens and LED bulbs read to the eye like daylight, so this is about lighting habits. Visible light is not the same as radio or power-frequency fields.

Smart speakers, plugs and lights keep a radio link to your router. Moving them out of the bedroom takes those connections away from where you sleep.

Walls that carry wiring for outlets and switches give off more field than a plain partition. Putting the headboard on a quiet wall keeps the bed farther away.

The breaker panel carries the current of the whole house, and its magnetic field passes through walls. Check what sits behind the wall at the head of your bed.

Connected to a wall outlet’s ground, a grounding sheet holds the sleeper at the building’s electrical potential. It blocks nothing and affects one field type.

Shielding paint has conductive particles that reduce radio signals passing through a wall. It suits the wall behind the headboard when the source is outside.

Hung over the bed, a Faraday canopy is a fabric enclosure meant to reduce outside radio signals. It is the heavy option, so measure the room before buying.

On the nightstand, a charger has a live adapter and the phone keeps its radios active. Charging elsewhere keeps both a few steps away from the bed.
