Wi-Fi connects electronic devices to wireless computer networks (wireless LAN) using electromagnetic radiation. They're installed in homes, schools, offices, stores, hotels, coffee shops, airports, libraries, hospitals, public buildings and even entire sections of cities. Wi-Fi signals are, unlike TV and radio signals, strong enough to penetrate concrete walls. Many health experts consider Wi-Fi radiation to be extremely dangerous to long-term health.
Based on the existing science, many public health experts believe it is possible we will face an epidemic of cancers in the future resulting from uncontrolled use of cell phones and increased population exposure to WiFi and other wireless devices. Thus it is important that all of us, and especially children, restrict our use of cell phones, limit exposure to background levels of Wi-Fi, and that government and industry discover ways in which to allow use of wireless devices without such elevated risk of serious disease.
We need to educate decision-makers that ‘business as usual’ is unacceptable. The importance of this public health issue can not be underestimated,” said Dr. David Carpenter, Dean at the School of Public Health, State University of New York.
Since Wi-Fi is so recent, no studies have yet been done on the long-term health effects of Wi-Fi. However, thousands of studies have been done on the health effects of mobile phones and mobile phone masts. These studies have found that mobile phone radiation can cause cancer!
Wi-Fi radiation penetrates the body, affects cell membranes and over time cells to lose their ability to function properly. It disturbs the body's natural energy field causing stress, fatigue and a weakened immune system. It can also cause headaches, concentration problems, dizziness, anxiety, memory loss, depression, hyperactivity, abnormal heart rates, seizures, epilepsy, nausea, skin rashes, insomnia, ringing ears, high blood pressure, brain damage, autism, diabetes, fibromyalgia, infertility, birth defects, DNA damage, leukemia, cancer, etc.http://safespaceprotection.com/harmful-effects-electromagnetic-fields.aspx
Children are especially vulnerable to Wi-Fi radiation signals because their nervous systems and brains are still developing. Their skulls are thinner and smaller, so the radiation penetrates their brains more deeply. Many schools are now using Wi-Fi but this is negatively affecting the learning abilities of children!

In the real world, true evidence of safety is the healthy functioning of the most vulnerable -- pregnant women and children -- when they are intentionally, unavoidably, or accidentally exposed to microwave radiation at approved levels. Yet an increasing number of people (around 15% according to Dr. Magda Havas), including children all over the world, are showing symptoms of ill health after exposure to WHO-approved levels of microwaves from transmitter towers, wireless internet and phones. The scientific research was there all along to show that this would happen, especially to children, but the science was simply not used by the WHO committee setting the standards.
To match the exponential growth in phones used by children, school boards are being persuaded that it’s necessary to install Wi-Fi transmitters every few meters in ceilings and walls throughout the entire building to give children a “21st-century learning environment.” Wi-Fi is apparently affordable even when school boards are too strapped to buy current textbooks and keep libraries open. Teachers and students aren’t hampered by limited access to inconvenient cables and plugs, but can download and upload anything from high resolution video to updated curriculum text, anywhere, anytime. This is the sales pitch from Cisco which seems irresistible.
According to the non-industry-funded research on health effects at these power levels, the schools’ Cisco Wi-Fi transmitters have overlapping zones of microwaves powerful enough to break DNA strands and cause the brain to release heat-shock proteins into spinal fluid.
In addition to microwaves from a phone held next to the head or in the hands above the lap, the exposed children are constantly absorbing powerful carrier waves with varying pulsed signals intended for thousands of users that are nowhere near the school. Millions of massively electrified antenna towers are on rooftops everywhere to send the signals to phones and wireless internet ports. They are blanketing us with an invisible fog of pulsed frequencies that can prevent our brains from making melatonin at night, at power levels capable of commandeering the heart’s own electrical rhythm.
It's time to tighten the standards and force manufacturers to comply so those documented biological effects do not occur, instead of discarding the victims and embracing the harmful standard. Other countries like France and Germany have done it for their children. It's time others countries follow suit.

Electromagnetic Radiation From Laptops and Wireless Devices Nuke Sperm in Proximity
In a report in the venerable medical journal Fertility and Sterility, Argentinian scientists describe what happened with sperm samples from healthy men were placed under a laptop.
The scientists got semen samples from 29 healthy men, placed a few drops under a laptop connected to the Internet via Wi-Fi and then hit download.
Four hours later, the semen was, eh, well-done.
A quarter of the sperm were no longer swimming around, for instance, compared to just 14 percent from semen samples stored at the same temperature away from the computer.
And nine percent of the sperm showed DNA damage, three-fold more than the comparison samples.
The culprit? Electromagnetic radiation generated during wireless communication, say Conrado Avendano of Nascentis Medicina Reproductiva in Cordoba and colleagues.
The safety risks of mobile phones, and wireless devices is a matter of constant contention between scientists and grave concern for consumers.
Just a fortnight ago an influential Council of Europe committee warned wireless devices, mobile phones and wireless internet should be banned from schools because they pose too great a risk to children̢۪s health.
"Our data suggest that the use of a laptop computer wirelessly connected to the internet and positioned near the male reproductive organs may decrease human sperm quality," they write in their report.
"At present we do not know whether this effect is induced by all laptop computers connected by Wi-Fi to the internet or what use conditions heighten this effect."
A separate test with a laptop that was on, but not wirelessly connected, found negligible EM radiation from the machine alone.
The findings fuel concerns raised by a few other research teams.
Some have found that radiation from cell phones creates feeble sperm in the lab, for example. And last year urologists described how a man's sitting with a laptop balanced on his knees can crank up the temperature of his scrotum to levels that aren't good for sperm.
So between the heat and the radiation from today's electronic devices, testicles would seem to be hard-pressed.
But that is not at all clear, said Dr. Robert Oates, who has managed to father two kids despite having both a laptop and an iPad.
The president of the Society for Male Reproduction and Urology, Oates told Reuters Health he doesn't believe laptops are a significant threat to male reproductive health.
"This is not real-life biology, this is a completely artificial setting," he said about the new study. "It is scientifically interesting, but to me it doesn't have any human biological relevance."
He added that so far, no study has ever looked at whether laptop use has any influence on fertility or pregnancy outcomes.
"Suddenly all of this angst is created for real-life actual persons that doesn't have to be," said Oates, also of Boston Medical Center.
According to the American Urological Association, nearly one in six couples in the US have trouble conceiving a baby, and about half the time the man is at the root of the problem.
While the impact of modern technology is still murky, lifestyle does matter, researchers say.
Earlier this month, a report in Fertility and Sterility showed that men who eat a diet rich in fruit and grains and low in red meat, alcohol and coffee have a better shot at getting their partner pregnant during fertility treatment.
"You should be keeping yourself healthy," including staying lean, eating healthy foods, exercising, not taking drugs and not smoking, agreed Oates.
And for those laptop worries, he mused, "I don't know how many people use laptops on their laps anyway."

Authoritative Verdict: WHO Admits That Cell Phones Cause Cancer
The UN’s health agency advised ‘pragmatic’ measures to reduce exposure, such as using hands-free kits and texting instead of calling.
The disturbing report marks the first time the WHO has linked mobiles with cancer, and follows earlier research linking just half an hour’s use a day with up to 40 per cent higher odds of brain cancer.
However the mobile phone industry was quick to point out that the devices had not been directly shown to cause cancer.
More than 70million mobile phones are now in use in Britain – more than one for every man, woman and child. Worldwide, the total tops five billion.
Dr Christopher Wild, director of the WHO’s International Agency for Research on Cancer, said: ‘Given the potential consequences for public health, it is important that additional research be conducted into the long-term, heavy use of mobile phones.
‘Pending the availability of such information, it is important to take pragmatic measures to reduce exposure, such as hands-free devices and texting.’
IARC’s conclusion follows a week-long review of all available scientific evidence by 21 scientists from 14 countries, including fresh research that has yet to be published.
The working group concluded that mobile phone use is ‘possibly carcinogenic’, a term which places the phones in the middle of five tiers of possible carcinogens.
They are below smoking, asbestos, sunbeds and other things which definitely cause cancer, but still a potential risk.
The review’s results could lead to the WHO redrawing its guidelines on mobile phone use. Until now, it has stated that there are no adverse health effects associated with it.
Dr Jonathan Samet, chairman of the working group, said while the evidence is still accumulating, it is strong enough to support the classification.
He added: ‘The conclusion means that there could be some risk and therefore we need to keep a close watch for a link between cell phones and cancer risk.’
The working group did not quantify the risk – but pointed to a study from last year that linked just half an hour of mobile phone use a day for ten years with an increased use of glioma, a type of brain tumour.
Some of the scientists behind that research said the figures were flawed and urged people not to worry, but others warned against dismissing the link.
Professor Denis Henshaw, a Bristol University radiation expert, said at the time: ‘Why should it come as a surprise that pressing mobiles to people’s ears increases the risk of brain tumours?’
The new review also found a possible link between mobile phones and non-cancerous tumours of the nerve that transmits information about sound from the ear to the brain.
‘Children should only use mobile phones for essential purposes and keep all calls short.’
MOBILE PHONE DOs
- Keep your mobile phone in your bag rather than in your pocket or next to your body. One study shows that men who wear cell phones near their groin risk reductions in their sperm count by up to 30 per cent.
- Send text messages or email where possible – don’t lean it against your body as you do so.
- Use a wireless headset. Moving your phone 20cm away from your head reduces radiation doses by about 98 per cent
- Keep still when you’re using it. If you’re on the move, whether walking or in a vehicle, your phone needs to use more radiation to keep track of you.
- Hold it away from you after dialling and watch the screen to see when it connects. Most phones emit more radiation when they’re trying to make contact.
- Go low-tech. The more sophisticated functions your phone has, the more power it must use to complete tasks.
MOBILE PHONE DON'Ts
- Talk for hours on end. The longer you use the phone, the higher a dose of radiation your brain is soaking up. Even a two-minute call has been found to alter the natural electrical activity of the brain for up to an hour afterwards.
- Use a regular wired headset, like the one that came with your phone. The regular wired headset has been found to intensify radiation into the ear canal.
- Allow your children unlimited mobile phone use. Young brains encased in thinner, more fragile skulls risk greater damage
- Do not make a call when the signal strength is one bar or less. The phone must work harder to establish a connection.
- Use the cell phone in enclosed metal spaces such as vehicles or elevators, where devices may use more power to establish connection. The metal enclosure also acts as a Faraday cage that traps the radiation and reflects it back on to the occupants.
The safety risks of mobile phones is a matter of constant contention between scientists and grave concern for consumers.
Just a fortnight ago an influential Council of Europe committee warned mobile phones and wireless internet should be banned from schools because they pose too great a risk to children’s health.
The Council’s Committee on the Environment, Agriculture and Local and Regional Affairs drew up a draft resolution urging governments to ‘take all reasonable measures to reduce exposure to electromagnetic fields’ from mobile phones and similar devices.
In March, in the Government's first update to the UK Mobile Phones and Health leaflet since 2005, officials for the first time warned mobile phone users to text or use hands free kits rather than make calls.
The Department of Health said this would reduce the user's exposure to reduce radiation emitted by the devices.
It stated there had been no 'clear evidence of adverse health effects' from the use of mobiles or from phone masts.
However, it added: 'As people have only been using mobile phones for relatively few years, the HPA advises that more research be carried out, especially to investigate whether there might be longer term effects.'
The UK Chief Medical Officer restated previous advice that children under the age of 16 should only use mobile phones for 'essential purposes' and should 'keep calls short.'
This was described as a 'precautionary' move as teenagers' bodies and nervous systems are still developing.
But a month earlier a University of Manchester study found there was no link between mobile phone use and increased levels of brain cancer.
A study by scientists at the university looked at data from the Office of National Statistics on rates of newly diagnosed brain cancers in England between 1998 and 2007.
It found no statistically significant change in the incidence of brain cancers in men or women during the nine-year period.
Lead researcher Dr Frank de Vocht, an expert in occupational and environmental health in the University of Manchester’s School of Community-Based Medicine, said a cancer epidemic was unlikely.
He said: 'Our findings indicate that a causal link between mobile phone use and cancer is unlikely because there is no evidence of any significant increase in the disease since their introduction and rapid proliferation.'
But at the end of 2010 a startling survey warned pregnant women who regularly use mobile phones could increase the risk of their children behaving badly.
If their offspring then start using the devices at an early age, the chance of problems climbs to 50 per cent, according to findings published in the Journal of Epidemiology and Community Health
Researchers in California found those exposed to mobile phones in the womb had a 30 per cent rise in behavioural difficulties at the age of seven.
But those exposed before birth and in their childhood, were 50 per cent more likely to have behavioural problems than those exposed to neither.
Children who used mobiles, but were not exposed in the womb, were 20 per cent more likely to display abnormal behaviour.
These latest studies have just contributed to a contradictory canon of research into mobile phone safety.
