Safety Tips for Wireless Devices

Updated 4/2/20

Reduce Your Exposure

There is enough science revealing adverse biological effects of electromagnetic radiation to be seriously concerned about our long term exposure, especially for children.  Even though more research is needed, current scientific literature points to broad health effects and precaution is warranted. Below is information and safety recommendations from a variety of medical, governmental and non-governmental sources to help you reduce exposure and protect yourself and your family from potential risks of wireless non-ionizing radiation. The first major governmental organization to provide more comprehensive safety guidelines, the California Department of Public Health, did so on December 13, 2017.

Cell Phone & Wireless Safety Tips

Reducing Your Exposure

Background: There is substantial and increasing research showing that non-ionizing  wireless (microwave) radiation acts as a broad biological toxin, similar to other chemical toxins we are exposed to. These microwaves are emitted from wireless devices we commonly use such as cell phones, cordless phones, tablets, laptops, wireless routers, wireless home monitoring systems, Smart Meters and cell towers. There are now many Baby Products on the market that are wireless. While small short exposures may not cause symptoms or much harm, we are now continuously and increasingly exposed to this radiation. Damage to cellular structures is cumulative. Reducing your exposure is recommended by the California Department of Public Health and an increasing number of physicians and scientists.

Biological harm demonstrated: Includes DNA damage, lipid injury, reproductive harm (sperm, ovary and embryo abnormalities), inflammation/oxidation, lower melatonin levels, immune dysfunction, stress protein synthesis, damage to the brain and nervous system, opening of the blood brain barrier, brain cancer, cancer promotion, harm to wildlife and plants. People with electrosensitivity report symptoms including headaches, fatigue, sleep disorders, heart palpitations, memory problems when around wireless devices. Electro sensitivity is recognized in Sweden as a true medical disorder and it is estimated that about 3% of the population experience it. A new review of the literature indicates about 18% of people have the condition to one degree or another and 0.65% cannot work because of it. (Bevington 2019)

Increasing exposure: We are increasingly exposed to a number of wireless devices in our homes and workplaces. These devices act as small cellular antenna similar to a cell towers that emit and receive information via radiofrequency radiation but at a lower power.

Current FCC safety standards are obsolete as they are based only on heat and not biological effects seen in lab and human experiments at far lower levels than currently allowed. Children are more vulnerable as their bodies are still developing, cells are more rapidly dividing thus they are more prone to DNA/cellular damage. Pregnant women are also highly vulnerable. Harm is cumulative. Precaution is critical.

Recommendations for safer use of wireless devices

1)       Wireless Devices are not Toys. Do not let babies or young children use a cell phone, tablet or laptop. AAP recommends no screen time age 2 or below unless FaceTime. Age 3-5 no more than 1 hour a day

2)       Children should use a cell phone for emergencies only. Consider giving your child a cell phone at an older age (14 years or above)

3)       Avoid sleeping with your cell phone next to your head or as an alarm unless phone is on Airplane Mode (it still works as an alarm when on Airplane Mode) Keep in another room. Use landline at night for emergencies

4)       Turn off Wi-Fi router at night and plug into an on/off surge protector for ease of use

5)       Hardwire Computers. Convert back to a wired connection in your house we all used to have. It is easy. Hardwire tablets as well. Visit

6)       Remove Cordless Phones. A cordless phone has essentially the same radiation as a cell phone and the base emits radiation as well. Use the landline for long calls. Replace the DECT cordless phone with a landline corded phone. Keep your landline if you have one

7)       Distance Matters.  Keep wireless devices away from the body. Keep tablets and laptops on the tabletop and not on the lap. FCC standards are for 7 inches (20 cm) away from the body.  No Cell phone in bra or pocket unless in Airplane Mode

8)       Airplane Mode When Not in Use and at night.  Download movies or games first for kids then view on Airplane Mode. Keep cell phones away from the head

9)       Do not keep router in the bedroom or near child’s room. The farther away the better. Turn router off at night

10)     When traveling in a bus or car download games or google map then turn your devices on airplane mode as the radiation is much higher as the device connects and disconnects to different cell towers as you move

11)     In the Car. Turn off bluetooth in the car when not in use and minimize use of cell phones in the car as the metal shields the wireless radiation and increases the levels in the car by a factor of 2 or more

12) Avoid Bluetooth and Wireless Earbuds as these put the RF radiation in the ears and in close proximity to the body and brain. Although lower in emissions long term use increases risk of health impacts.

13) Keep Your Landline.  A landline is still the most sophisticated and effective emergency line and essential for those who are electrosensitive or who wish to reduce their risk of brain tumors from using a cordless phone. You can purchase a corded phone, we all used to have, at number of retail outlets.

14)    Consider removing your Smart Meter and switch back to analogue with a human meter reader. Lamech in 2014 reported an increase in symptoms when Smart meters were rolled out in Australia.  In California call PG&E Opt Out  at 1-866-743-0263 and ask to Opt Out or call your local utility as 24 states now have laws that allow you Opt Out of Smart Meters.

California Department of Public Health Guidelines on Cell Phone Radiation

December 13, 2017 the California Department of Public Health (CDPH) released its guidelines on “How to Reduce Exposure to Radiofrequency Radiation for Cell Phones”  CDPH Press Release Dec 13, 2017 . The CDPH notes that cell phone use is increasing dramatically thus guidelines are needed. See our blog for more information MDSafeTech Blog

The new CDPH guidelines  provide practical steps to reduce exposure to radio frequency energy from cell phones. That includes:

  • Keeping the phone away from the body
  • Reducing cell phone use when the signal is weak
  • Reducing the use of cell phones to stream audio or video, or to download or upload large files
  • Keeping the phone away from the bed at night
  • Removing headsets when not on a call
  • Avoiding products that claim to block radio frequency energy. These products may actually increase your exposure.

Cell Phone Radiation & Children’s Health: What Parents Need to Know

Pediatricians remind us that children are not just little adults but are developing humans that are especially susceptible to the environment and toxic exposures. They state, ” The AAP reinforces its existing recommendations on limiting cell phone use for children and teenagers. The AAP also reminds parents that cell phones are not toys, and are not recommended for infants and toddlers to play with.

Here are their recommendations. You can also visit the AAP site AAP Cell phone tips

Cell Phone Safety Tips

for Families

  • Use text messaging when possible, and use cell phones in speaker mode or with the use of hands-free kits.
  • When talking on the cell phone, try holding it an inch or more away from your head.
  • Make only short or essential calls on cell phones.
  • Avoid carrying your phone against the body like in a pocket, sock, or bra. Cell phone manufacturers can’t guarantee that the amount of radiation you’re absorbing will be at a safe level.
  • Do not talk on the phone or text while driving. This increases the risk of automobile crashes.
  • Exercise caution when using a phone or texting while walking or performing other activities. “Distracted walking” injuries are also on the rise.
  • If you plan to watch a movie on your device, download it first, then switch to airplane mode while you watch in order to avoid unnecessary radiation exposure.
  • Keep an eye on your signal strength (i.e. how many bars you have). The weaker your cell signal, the harder your phone has to work and the more radiation it gives off. It’s better to wait until you have a stronger signal before using your device.
  • Avoid making calls in cars, elevators, trains, and buses. The cell phone works harder to get a signal through metal, so the power level increases.
  • Remember that cell phones are not toys or teething items.

Environmental Working Group

The Environmental Working Group released cell phone warnings in 2009 and 2013. Their latest 2016  version, Easy Ways to Reduce Kids’ Exposure T Cell Phone Radiation, notes that 5 countries have issue warnings to reduce exposure to cell phone radiation. Their tips for reducing a family’s exposure include:

Limit children’s use of cell phones

  • Choose a landline for everyday calls.
  • Don’t offer the phone as a toy while on the go or running errands.
  • If your kids use your phone to play games, switch on airplane mode.

Keep your distance

  • Use a headset or speaker while talking on the phone, rather than holding it directly to your ear.
  • While on a call, keep the phone away from your body – say, on a table in front of you, instead of your pocket.
  • Store your phone away from your body, not under your pillow or clipped on your belt.

Choose a good case 

Some cell phone cases may minimize radiation exposure, while others force the phone to work harder and emit more radiation. Click here to learn more about how to choose the best cell phone case.

Text when possible

Texting emits less radiation than voice calls.

Seek a strong signal

Radiation levels are significantly higher when your signal is poor.

  • Use a headset or speaker while talking on the phone, rather than holding it directly to your ear.
  • While on a call, keep the phone away from your body – say, on a table in front of you, instead of your pocket.
  • Store your phone away from your body, not under your pillow or clipped on your belt.


Dr. Joel Moskowitz

Dr. Joel Moskowitz , Director of the Center for Family and Community Health, School of Public Health, University of California, Berkeley, has also written a list of cell phone safety tips with a call to action.  He highlights the fact that over 230 scientists have signed on to the international Scientists Appeal, at, asking the World Health Organization to reevaluate it’s safety standards to include consideration of biological effects, additive effects and sensitive populations such as those with electrosensitivity.  His safety tips include using your landline for long calls, keeping a distance between you and your device as much as possible and waiting for a good signal to make a call as  your device will emit less radiation if the signal is strong.

World Health Organization

The World Health Organization has weighed in with information on health effects of cell phones and state that “Given the large number of mobile phone users, it is important to investigate, understand and monitor any potential public health impact.” They acknowledge that the WHO group the international Agency for Research on Cancer (IARC)  has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B). They also note that “The international pooled analysis of data gathered from 13 participating countries found no increased risk of glioma or meningioma with mobile phone use of more than 10 years……The researchers concluded that biases and errors limit the strength of these conclusions and prevent a causal interpretation.”

Their current conclusion, however,  is “To date, research does not suggest any consistent evidence of adverse health effects from exposure to radiofrequency fields at levels below those that cause tissue heating”.  WHO Info on cell phones and health
