EMFs & Bedrooms


Common EMFs in Bedrooms and Sleeping Areas

24 Common EMF Sources found in
Bedrooms and Sleeping Areas

The following is a list of 24 EMF sources commonly found in bedrooms and sleeping areas.

The Building Biology profession emphasizes the importance of good sleep and therefore recommends turning all bedrooms into low-EMF sanctuaries.  Thus try to remove or reduce your exposure to these items as much as possible.

We’ve included a recommended solution for many of these. Some of these outbound links may be affiliate links to help support our mission of EMF education.


Plugged-in Bedside Lamps

Ungrounded lamps (which contain the types of plugs with two prongs instead of three) can produce high AC electrical fields. If the lamp is on a bedside table, you or a loved one will be sleeping in this electric field.

These fields can be eliminated by grounding and shielding your cord properly or by replacing the lamp with a battery powered version.

A Low EMF Solution

Here are some options for battery-powered bedside lamps. FYI, that many of these use LED bulbs.


Electric Blankets

Electric blankets can give you the double whammy of magnetic and electric field exposure. The magnetic fields are from the heating element within the blanket and the electric fields are from the ungrounded plug.

Instead of keeping these plugged in all night, we recommend plugging these in before bedtime and then unplugging them once you enter the bed.

Remember to not just turn them off, but make sure the power supply to the blanket is completely turned off.

A Low EMF Solution

As mentioned above, a great solution is to warm your bed with these prior to actually going to bed and then unplug them once you decide to turn in for the night.


Heating Pads

Similar to electric blankets, these can have elevated AC electric and magnetic fields when plugged in and functioning. Try to limit your exposure to these when possible

A Low EMF Solution

Make sure these are unplugged when not in use.

Alarm Clocks

Alarm clocks often produce two or three of the man-made EMFs that we keep an eye out for: AC electric fields, AC magnetic fields and radio frequency fields.

It’s also problematic that the clocks are also often on a nightstand or in close proximity to where people sleep.

Below are some of the types that are commonly found.


Analog Alarm Clocks

Analog clocks can produce surprisingly high magnetic fields from the inner-workings of the clock and electric fields from the ungrounded and unshielded cords.


Digital Alarm Clocks

While these are obviously different technology than the analog models, the concerns are similar with regard to magnetic and electric fields.


Alarm Clocks with Wi-fi

Alarm clocks with wi-fi or bluetooth subject you to radio frequency fields, as well as the previously mentioned magnetic and electric fields.

A Low EMF Solution

The best solution would be to utilize an old-timey keywound alarm clock.

Another good solution is to use a battery-powered digital clock that is across the room.


Electrical Wiring

Any electrified circuit in a home will (unless it has shielded electrical conduit) have some level of AC electric fields radiating from the electrical wiring within the walls.

We go over this more in more detail in our section on AC Electric Fields.

A certified electrician can install a “remote cut-off switch” or “on-demand switch” that will de-energize the electrical circuit in and around a bedroom.

This means that with the push of a button on a remote (a non-wifi, IR remote) one or more electrical circuits will be de-energized and the electrical field level will disappear or be greatly diminished.

This is one of those areas where an EMF specialist can really be of assistance, as the mapping out of the breaker panel is instrumental in determining which electrical circuits to turn off.

Do not attempt this yourself, unless a certified electrician has signed off on the safety of your breaker panel, the breakers and the surrounding electrical system.

Bedframes and Mattresses

Many of the mattresses, boxsprings and bedframes on the market today can actually elevate your man-made EMF exposure.

Below are some commonly found furniture components to be aware of:


Metal Bed Frames

Metal bed frames and components can amplify both AC electric fields and radio frequency fields.

Wooden bed frames are common, and often more attractive, alternative.

This isn’t to say that you can’t have any metal components (drawer slides, etc…), but minimizing these will keep your exposure levels lower.


Traditional Mattresses and Boxsprings That Have Metal Springs

The presence of metal springs in mattresses and boxsprings can accentuate electric fields around the people (or pets) sleeping on them.

We recommend switching to models of both that don’t have metal springs.

Here’s an example of an all latex bed that doesn’t have springs.



Adjustable Beds

Many adjustable beds are continually plugged in and made of a lot of metal parts. This will subject the occupants to increased AC electric fields.

We recommend the use of standard, wooden platform beds without metal springs.



Waterbeds may lead to increased electric field levels for the occupants due to the conductivity of the water itself.


Smart Mattresses

There are mattress models on the market now that will track your sleep duration and quality.

One can see the allure of this functionality, but, in order to communicate this information, mattress chip components will produce radio frequency radiation.

This is in addition to any elevated electric and magnetic fields produced by the electronics within the mattresses.

A Low EMF Solution

If you’re able to keep things simple by purchasing a wooden bedframe and a mattress that doesn’t have metal springs within.

A latex mattress could be a good choice for many.
