What's Wi-Fi Doing to Us? Wi-Fi Could Harm Your DNA

Team - 4:53 AM

We are engulfed by electromagnetic fields all day everyday, and the fields are only getting stronger as technology progresses and spreads. The health effects are of increasing concern, as it has been shown they not only affect individuals, but also harm DNA passed along to offspring.

Wi-Fi routers, cell phones, cordless phones, baby monitors, electric blankets, alarm clocks—all of these devices are damaging, says electrical engineer and environmental consultant Larry Gust. He discussed the dangers and how people can protect themselves in a video presented by Electromagnetic Health this week.

Here’s a look at the health effects, recommended maximum levels of exposure, the levels most people are exposed to, and tips on how to protect yourself.

Wi-Fi routers, cell phones, cordless phones, baby monitors, electric blankets, alarm clocks—all of these devices create electromagnetic fields that can damage DNA, affecting cell growth and processes as well as offspring.

Health Effects Overview

Dr. Martin Blank, who studies the effects of electromagnetic radiation at Columbia University, pointed out in a 2012 lecture uploaded to YouTube that the damage to DNA disrupts normal cell growth and protein production.

He cited studies that have shown DNA damage causes cancer. Illustrating the impact of the field emanated from a simple daily device, he said it has been shown electric blankets greatly increase a woman’s chance of miscarriage.

Electric field health effects:

-Aggravated allergies
-Disturbed sleep
-Night sweats
-Heart palpitations
-Muscle and nerve pain
-Waking tired
-Daytime irritability
-Bed wetting in children

Radio frequency health effects:

-Headaches
-Irritability
-Memory problems
-Inability to concentrate

Electric, Magnetic Field Exposure

Recommendations for the maximum exposure in electric fields vary from about 3 volts per foot at the upper end of the spectrum to 1.5 volts or fewer per foot at the lower end. The typical bedroom has 3 to 9 volts per foot.

The World Health Organization (WHO) reports that the maximum level for a magnetic field in a home should be 3 to 4 milliGauss.

In Marin, Calif., a 4-year-old girl had an 80 milliGauss field around her bed and in the play yard she frequented, recalled Gust. She was lethargic, had no appetite, and had rectal bleeding. As soon as the field was cleared, her symptoms vanished.

Maximum Recommended Levels of Radio Frequency Exposure


The BioInitiative Report was produced by a working group of doctors. Dr. David Carpenter, director of the Institute for Health and Environment at the University of Albany co-edited it. The Building Biology Report was released by the International Institute for Building-Biology & Ecology, a non-profit research and advisory institution.

Experiment finds that shrubs die when placed next to wireless routers

Plants and people have been shown to absorb radio signals Wi-Fi emits Scientists divided over whether this is enough to cause damage to tissue Some experts believe the negative effects observed in the latest study could be due to heat emitted by the Wi-Fi routers

A group of schoolgirls claims to have made a scientific breakthrough that shows wifi signals could damage your health – by experimenting with cress.

In a twist on the traditional science project of growing cress on a paper plate, the 15-year-olds set out to test whether mobile phone signals could be harmful.

They say the result could affect millions of people around the world.

An experiment in Denmark claims to show that Wi-Fi signals are powerful 
enough to kill cress seeds after just 12 days of exposure

Pupil Lea Nielsen said: ‘We all thought we experienced concentration problems in school if we slept with our mobile phones at the bedside, and sometimes we also found it difficult sleeping.’

However, because they were not able to monitor their brain activity at their school in Denmark, they chose to monitor plants near wireless routers, which emit similar radio waves to mobile phones.

When the girls grew trays of garden cress next to wifi routers, they found that most of the seedlings died.

In the experiment, they placed six trays in a room without any equipment and another six trays in a room next to two routers.

Over 12 days many of the seedlings in the wifi room turned brown and died, whereas those in the others room thrived.

But critics claim that the cress seedlings left next to the routers probably struggled because they were dried out by heat emitted from the devices.

Kim Horsevad, the students’ biology teacher at Hjallerup School, said: ‘This has sparked quite a lively debate in Denmark regarding the potential adverse health effects from mobile phones and wifi equipment.’

The results will bolster the findings of researchers in Holland, who found that trees exposed to wireless radio signals suffered from damaged bark and dying leaves.

There is little evidence, however, that wireless emissions pose any danger to human health. Wifi signals use very low intensity radio waves – 100,000 times less powerful than a microwave.

Sitting in a wifi hotspot for a year would only expose you to the same dose of radio waves as making a 20-minute mobile phone call.

Wireless radio waves also diminish significantly with distance.

There is some debate about whether the negative effects were due to the cress seeds 
drying from the heat emitted by the computer Wi-Fi routers

Those who want to reduce their exposure to wifi emissions should sit more than 3ft away from their router and place their laptop on a table rather than on their lap.
WHY ARE PEOPLE CONCERNED ABOUT WI-FI RADIATION?

Wi-Fi signals use very low intensity radio waves. Whilst similar in wavelength to domestic microwave radiation, the intensity of Wi-Fi radiation is 100,000 times less than that of a domestic microwave oven.

The type of radiation emitted by radio waves (Wi-Fi), visible light, microwaves and mobile phones has been shown to raise the temperature of tissue at very high levels of exposure.

This is called a thermal interaction, but researchers are divided as to whether the radiation we receive daily can cause damage.

The UK Health Protection Agency (HPA) has been monitoring the safety of Wi-Fi. It says people using Wi-Fi, or those in the proximity, are exposed to the radio signals it emits - and some of the transmitted energy in the signals is absorbed in their bodies.

However, the signals are very low power. Sitting in a Wi-Fi hotspot for a year results in receiving the same dose of radio waves as making a 20 minute mobile phone call.
But there is some debate over whether the negative effects were due to the cress seeds drying from the heat emitted by the computer Wi-Fi routers used in the experiment.

The study will raise fears that Wi-Fi radiation may also be having an effect on the human body and will lend weight to parents and teachers who have campaigned to stop wireless routers being installed in schools.

Three years ago, research in Holland showed that trees that were planted in close proximity to a wireless router suffered from damaged bark and dying leaves.

The Dutch scientists carried out their research on ash trees which had been suffering with bark bleeding and dying leaves.

The city of Alphen aan den Rijn, in the West of the country, ordered the study five years ago after officials found unexplained abnormalities on trees which they did not believe had been caused by any known viral infection.

The trees were exposed to six sources of radiation with frequencies ranging from 2412 to 2472 MHz and a power of 100 mW at a distance of just 20 inches.

Trees placed closest to the Wi-Fi radio developed a ‘lead-like shine’ on their leaves that was caused by the dying of the upper and lower epidermis.

This would eventually result in the death of parts of the leaves, the study found.

The study will raise fears that Wi-Fi radiation may also be having an effect 
on the human body and will lend weight to parents and teachers 
who have campaigned to stop wireless routers being installed in schools

In the Netherlands, about 70 per cent of all trees in urban areas show the same symptoms, compared with only 10 per cent five years ago, the study found. Trees in densely forested areas are not affected.

But scientists have expressed scepticism about research such as this.

At the time of the study, Marvin Ziskin, a professor of radiology and medical physics at Temple University in the U.S. said: 'Stuff like this has been around a long time . . . there's nothing new about Wi-Fi emissions. Scientifically there's no evidence to support that these signals are a cause for concern.’
