 Tips and resources from our partners at Environmental Health Trust 

1. Distance is Important

One basic, very important concept is “Distance Is Your Friend.” The amount of wireless radiation absorbed into people decreases very rapidly when you increase the distance from wireless devices.

Decrease your exposure by increasing your distance from wireless emitting sources. For example, always keep cell phones and wireless laptops away from your body.

2. Identify Sources in Your Home

Take a look around your home. How many wireless things do you have?

Become aware of the various emitting sources in your surroundings first so you can address each one step by step.

Keeping a distance from devices is just the first step in reducing your risk. The next step is identifying safer ways to get the connections you need but without the wireless radiation.  Here is a list of things that emit wireless commonly found in homes: computers, smart speakers, Wi-Fi router, gaming consoles, cordless phones, cordless mouse, mobile phones, and wireless security systems. 

3. Get to Know Airplane Mode

“Airplane mode”, also known as “flight mode,” is a setting on your wireless device that stops the microwave radiation emissions. It turns antennas to OFF. Learning how to use airplane mode is one of our most important tips. On some devices airplane mode only turns cellular antennas, so you also need to check and turn off other antennas that could be on such as Wi-Fi or Bluetooth. 

On every computer, laptop, tablet, or WTD, there is a function key that turns OFF the Wi-Fi transmitter. There is also a function key that turns OFF the Bluetooth transmissions.

Whenever you hand a child a technology device such as cell phone, tablet, or laptop, please set the Airplane mode to ON, and Wi-Fi to OFF, and Bluetooth to OFF.

Devices should be used on a table and never on a lap.

4. Get a Corded Landline

Home cordless phones emit radiation like cell phones. Most cordless phone base stations constantly emit high levels of microwave radiation regardless of whether or not any connected handset is in use.

Corded landlines have no wireless radiation emissions. So every home should have a corded landline (with a curly cord to the handset) if possible. Then you can forward cell phones to your home line while you are at home. Prefer the landline corded phone for most voice conversations.

If you cannot get a copper landline you can use a Voice over Internet Protocol system or purchase a telephone line connection from your Internet provider.

5. Reduce Your Mobile Phone Radiation Exposure


First, try to minimize your overall cell phone use to decrease the time you are exposed. For adults who must use a mobile phone: 

– Use speaker phone or a plug-in earpiece to keep the phone away from your brain and body, and when you are not using the phone be sure to power off or set the phone on Airplane/Flight mode and the Wi-Fi to OFF and the Bluetooth to OFF.

– Prefer texting instead of voice calls and hold the phone out, away from your body when you press “send,” and do not rest your phone against your abdomen as you text.  

– Do not carry a powered ON mobile phone in your pocket or bra. 

– Turn automatic updates off. Reduce active Apps. Cell phones emit radiation constantly, even when you are not actively using them. Even if you turn wireless antennas off, they are still emitting magnetic fields so power them 100% off before you carry them near your body.

– Children should not use mobile phones except for emergencies.

Note: The safest way to use a cell phone is to turn it off and use a corded landline. Environmental Health Trust has a detailed step by step on reducing cell phone radiation here. 

6. Turn It Off When Not In Use

We want to be clear that turning things “off when not in use”  still results in significant wireless exposure. EHT recommends you swap out wireless devices with safe wired connections. However, for many people, they feel overwhelmed or are unable to do this immediately. That is why turning things off when not in use is often the first step people take. Then we highly recommend you move to the next step which is swapping out wireless devices with safe corded connections. 

Wireless enabled devices are always transmitting radiation even when you are not surfing the internet or using the device to talk or message. The only way to stop these emissions is to set the wireless antennas to OFF.


Wi-Fi devices continuously check in with their main network (cell tower or Wi-Fi router) to be sure a connection exists. This radiation activity is called a digital handshake.

For example, a Wi-Fi router emits a beacon signal at regular intervals to signal the available network (whether or not any person or machine is using the network). Similarly, a Wi-Fi enabled tablet or other personal use devices will also signal at regular intervals hunting for a network (whether or not a person is using that connection). Those signals are all radiation emissions.

You can easily decrease your family’s firsthand and secondhand radiation exposure by turning off wireless networks and devices whenever you are not actively using them, such as at night while you sleep. 

Unplugging wireless devices (and their related gear)—for example, gaming, entertainment, and computer systems—when not in use also saves significant energy and makes all-around good sense.

Note: Turning Wi-Fi off when not in use only eliminates wireless exposures while the WiFi is OFF.  However, you will still be exposed when the Wi-Fi is ON. Therefore, be aware you are still getting significant exposure when the Wi-Fi is ON.  

7. Prefer Corded Technology Connections

For home phones (landline), internet, printer, speakers, and entertainment gear, connect by cord or cable with all wireless features off.

Wi-Fi Internet Connections at Home: As an easy first step, power off the Wi-Fi router at bedtime. Then ask your internet provider how to connect with plug-in cords and turn off the antennae feature of the modem or router. Many companies allow you to manage the wireless settings online and you can simply turn it off via the internet. Sometimes a swap to a non-wireless modem is necessary.

Wire Up Game Stations and Controllers: Choose gaming devices that have the option to connect the hand controllers with a cord.

Hardwire Accessories (Printer, Keyboard, Mouse, Speakers, etc.): Wi-Fi printers, your cordless mouse, and your virtual assistant speaker are a hidden source of constant Wi-Fi emissions, just like a Wi-Fi router or cordless phone base. 

Remember: If a user or tracking device is wireless, it has wireless radiation emissions.

8. Power Off Wireless Devices When Driving

Power off mobile phones and wireless connectivity in vehicles. Mobile devices distract drivers even if hands-free. Mobile phones and streaming tablets and laptops also emit higher power radiation during travel because the metal surroundings create radiation hotspots inside the driver and passenger areas of your vehicle. 

Use an old fashioned GPS without wireless. Plan ahead so that you do not need to use any brain phones or wirelessly enabled devices in the car. Going on a road trip and your children want to watch movies? Before you leave, download the movies onto the device so that during the trip wireless access is not necessary. Call your car manufacturer to learn how to turn the wireless antennas ( Bluetooth or Wi-Fi) to OFF in the car. 

9. Protect Children and Pregnant Women

Rethink how you use mobile phones when you are near children. Children’s skulls are thinner than adults’ and their brains are still developing. Hence, radiation from mobile phones penetrates more deeply into their brains and is likely to cause more damage.

For example, do not use a mobile phone while an infant is on your lap, and do not carry your mobile phone in your baby carrier.  Keep a transmitting mobile phone or wireless device away from a child’s brain and body.

10. Safeguard Your Sleep

Pew Research reported that 75% of children sleep every night with their mobile phone beneath their pillow. Wireless radiation and blue light impacts sleep. So be sure to power off all screens and electronics well before bedtime.

Need an alarm on your phone? You can set the phone to Airplane/Flight Mode ON and the Wi-Fi and Bluetooth to OFF and still use the alarm feature.

Many newer TVs, gaming systems, and computers plugged into electricity or on battery power will have radiation emissions even if in power off mode, so it is best to remove them from the bedroom or completely disconnect them from their power source.

Be sure to charge cell phones and tech devices outside the bedroom, because charger gear generates other types of electromagnetic fields that are also linked to health issues.

Locate screens in family areas—not in bedrooms.
