Pregnancy and EMFs


How to protect yourself and your Unborn Baby from EMfs

Pregnancy and EMFs: Protection for Both Mother and Baby

The development of your child in utero is an absolute miracle of pregnancy. This guide will help you limit your EMF exposure during these important developmental months.  We’ll focus on the four man-made EMFs and give you mitigation tips for each.

The mitigation steps undertaken here will lower the exposure of the rest of your family and your pets, as well.

Below are a distillation of those tips and the highlighting of some of the more important ways to reduce or eliminate the EMF radiation exposure for women during their pregnancy.

If you have any questions, please contact us!

Most of these tips are applicable to making your home a low-EMF environment for everyone in your family, in utero or not.

Worth the read, if even a small reduction in EMF exposure can be attained.


Radio Frequency Radiation Sources To Be Aware of While Pregnant

To learn more about radio frequency (RF) fields, please click the following link to visit our chapter on the subject.

Learn about Radio Frequency Fields.

Below are some point sources of radio frequency radiation. Many are common and thankfully most can be mitigated without a lot of effort.


Cell Phones and Pregnancy

Cell phones are continually giving off radio frequency radiation as the devices communicate with cell towers, wifi routers and bluetooth devices.

Here are three tips:

01 – A simple solution to reduce this exposure for you and your child is to place your phone in airplane mode when you’re not waiting for an important phone call.01

02 – Another important habit to get into is to not sleep next to your cell phone if it isn’t in airplane mode. This is an important reduction in RF radiation for you and your unborn child.

03 – When you are browsing, texting or calling on your phone make sure you aren’t resting the phone on your belly, directly adjacent to your child. Keep it at arm’s length, as much as possible.

01 – Airplane Mode & Cell Phones

Our chapter on how to place your phone in airplane mode will be coming shortly.


Wifi and Wifi Extenders

Wi-fi routers and extenders/boosters, like cell phones, are a common source of radio frequency radiation.

If you can stop using wi-fi entirely and only use hardwired internet connections, please do so. Hardwiring your internet isn’t difficult and will eliminate your family’s exposure to this entirely.

If you’re unable to do so, due to security, medical or housing arrangements, get in the habit of keeping it off as much as possible.

Additionally, try to spend as much time or sleep in areas of your home as far away from the router and other transmitters as possible.02

One product we recommend to our clients is an infra-red remote on/off switch. This switch basically plugs into a socket and then your router is plugged into the switch and can be turned on and off with a remote control.

If you have to occasionally use wifi, you can utilize this to turn the router on and then immediately turn it off after you’re done.

Learn more about this on/off switch.


02 – On/Off Switches

Turning off you Wi-Fi can be achieved by the following means:

A – Some internet providers that have a wireless router bundled with their service modem have apps that you can use to remotely turn the wireless router on and off.

B – Put your wireless router on a mechanical timer that you plug into your electrical outlet. This will turn it off every day at a selected time.

C – Utilize a remote IR kill switch. Right before you go to bed, you can turn off your wireless router with the click of a button and then turn it back on when you wake up.


Cordless Phones

Cordless phones produce a shockingly high amount of RF radiation and the docking stations are often found in multiple rooms.

When you’re pregnant or have young children it’s best to just get rid of these and utilize a corded land-line.


Baby Monitors

If you have other young children, you probably are utilizing baby monitors. Most, if not all, of these produce radio frequency fields as they communicate.

Luckily, these can be hardwired to eliminate the RF exposure to you and the rest of your family.

Read our Low EMF Nursery guide to learn more.


Entertainment Technology

Entertainment consoles are littered with all types of devices that produce radio frequency radiation through the use of wifi, bluetooth and/or cellular technology.

Common sources of radio frequency radiation in the average living or TV room are:

– Smart TVs
– Wireless Cable Boxes (Comcast, DirectTV, Dish Network)
– Gaming systems (Playstations, Xbox and Nintendo)
– Smart Speakers (Alexa, Google Home)
– DVD players with smart features
– Digital Media Players (Fire TV, Apple TV, Roku)
– Wireless speakers (Sonos, Bose)
– Bluetooth computer peripherals (wireless mouse and keyboard)

These fields can be mitigated by turning off the wireless and bluetooth functionality and running a hardwired ethernet connection to the devices instead.

At a minimum, put the devices on a power strip that can easily be turned off when not in use.


Smartwatches and Fitness Trackers

These should be in airplane mode with wifi and bluetooth turned off. Read our guide on how to do this.

Otherwise you and your child will be getting RF exposure all day and night.


Other Internal RF Sources

Other common internal sources of radio frequency radiation are:

– Wireless security systems
– IoT (The Internet of Things or smart home products)
– Bluetooth children’s toys

Click on the links above to reduce your exposure to and learn more about each.


External RF Sources

Two common sources of external radio frequency sources are wireless utility meters and close proximity cell towers.

Wireless utility meters can be swapped out for non-transmitting models.

Cell phone towers should be avoided as much as possible.

Read our guide on locating cell towers to lower your EMF exposure.

How to Test for RF Fields

You can survey radio frequency fields with an RF Meter.

Our current favorite beginner’s RF meter is the Trifield TF2.

Visit our Best EMF Meters of 2020, to learn more about the Trifield TF2 and other beginner, intermediate and professional level RF meters.


AC Magnetic Field Sources
To Be Aware of While Pregnant

These are all the common sources, internally and externally, that can affect you, your unborn child and your family.

Not familiar with AC magnetic fields? We have a chapter solely devoted to the subject.

Learn about AC magnetic fields.


Power Lines

Overhead and underground power lines are common sources of elevated magnetic field levels within homes.

Shielding these can be difficult, so your best bet is to increase your distance from the source.

You don’t want to sleep in areas with elevated magnetic field levels. This is a universal tip and not solely applicable to when you are pregnant.

Sometimes you may come across an unavoidable source (like a fridge or breaker box on the other side of a wall). You may need to try and shield against it in those circumstances.

Learn more about magnetic field shielding.


Kitchen Appliances

Anything with a motor, condenser, or an electric clock will have some magnetic fields.

Examples of these are refrigerators, furnaces, stoves and dishwashers.  Microwave ovens produce RF radiation and are another to look out for.

The kitchen can be a real exposure problem as pregnant mothers can often spend a lot of time around these appliances with their unborn baby directly adjacent to the source.

It’s important to understand the high exposure areas of the kitchen and to seek out the lower exposure areas when in the area.

An EMF consultant can survey for you or you can get an EMF meter and do the sleuthing yourself (see below).


Wiring Errors

Electrical wiring errors are also common causes of elevated magnetic fields in homes.  These can be quite large and are important to survey for.  Especially in the bedrooms and other places of the home that are occupied frequently.

Click here for more information on how to mitigate these errors.


Stray Current on Utility Lines

A surprising, yet not uncommon, source of magnetic fields are the stray electrical amperage coming into a home from water, gas, telephone and cable utility lines.

Learn more about this phenomena.

How to Test for Magnetic Fields

You can survey magnetic fields with a gaussmeter. Decent gaussmeters are affordable and easy to use.

Visit our EMF Meter Reviews page to learn which gaussmeter or multi-use meter we recommend.


AC Electric Field Sources To Be Aware of

If you’re not familiar with AC electric fields, please click on the link below to read our chapter on the subject.

Learn about AC electric fields.

AC electric fields can originate from external sources such as overhead powerlines, but a majority of the exposure is from internal sources.

Below are some of the internal sources to keep an eye out for in relation to areas where you sleep and spend a lot of time.


Energized Electrical Circuits

In most homes, if an electrical circuit is energized you’re going to have the presence of electrical fields. 

Having an electrician install an on-demand switch to de-energize the room will alleviate the fields.

Some people recommend turning off the breakers manually to achieve the same effect, but we don’t recommend doing this without having a certified electrician come out and sign off on the safety and the condition of the breaker box.



Cords, Cords and More Cords

Power and charging cords effectively become extensions to the energized electrical circuit. If not properly shielded, they will produce electric fields, as well.

Examples of these are:

– light cords
– plug-in strips
– extension cords
– phone charger cords
– product cords

When we do surveys, we’ll sometimes see half a dozen cords snaking around and underneath people’s beds. If you can’t get a shut-off switch installed, get rid of all these cords.

You can purchase battery powered clocks and lights and all your charging should be done in a different room entirely.

How to Test for Electrical Fields

 You can survey AC electric fields with an electrical field strength meter.

Visit our EMF Meter Reviews page to learn which field strength meter or multi-use meter we recommend.


Dirty Electricity Sources
and Pregnancy

We have a full chapter on dirty electricity in our guide. Click the link below to view it.

Learn about Dirty Electricity.

Dirty electricity can be a little tricky, so we recommend getting a power line meter (more information below) to measure the rooms in your home. 

Elevated levels can be reduced with plug-in filters (more information below). If the levels are extreme there are whole home filters that electricians can install.

DE is most commonly caused by lighting fixtures, light bulbs and various tech devices.


Light Bulbs

Many of the newer light bulbs achieve their cost savings by continually turning on and off at extremely high rates.  Thes include CFL/LED/Fluorescent/Halogen light bulbs.

This causes dirty electricity and can be less pleasing to the eye. To ensure your a comfortable environment during your pregnancy, we recommend the use of traditional incandescent bulbs.


Dimmer Switches

Dimmer switches work in the same manner as the newer light bulbs.

We recommend swapping these out for normal light switches, but if you decide to keep them make sure you aren’t sleeping or spending time in close proximity to the fixture.


Device Power Supplies

Most devices have power transformers that can influence the dirty electricity levels on your room’s electrical circuit.

Just something to be aware of when testing for levels.

How to Test for DE

You can test your home for elevated dirty electricity levels with a power line meter.

Two popular meters are the Greenwave and Stetzerizer meters.

Visit our Best EMF Meters of 2020, to learn more about our meter recommendations.


A Recap of How to Limit Your
EMF Exposure While Pregnant
