Is It Safe To Be Near a WiFi Router?

Trust your own experience instead of waiting for studies that may never exist. Exposure to certain frequencies do affect how human bodies function, but most studies are hard to trust based on their funding source and obvious bias. Wireless routers – as well as Bluetooth, cell towers and similar wireless systems – emit electromagnetic radiation in the low-gigahertz frequency. This level is considered potentially dangerous to people, and the danger is compounded by several factors: just like the wireless signals themselves, the electromagnetic frequencies (EMFs) can pass through walls and penetrate into human tissues.

Symptoms may increase if the person has a thinner layer of protective fat (often due to a diet deficient in quality fats, e.g vegans and vegetarians) shielding the brain and central nervous system from radiation

Is WiFi radiation harmful?

Much of North America and Western Europe, Japan, Australia and New Zealand rely on guidelines put out in 1998 by the International Commission on Non-ionising Radiation Protection (ICNIRP). ICNIRP guidelines allow exposure of the public to radiation at the frequencies emitted by cellphone towers and WiFi transmitters up to a power density of 10 watts per square meter.

According to the government of Canada, the amount of radiofrequency EMF emitted by WiFi that is absorbed in your body largely depends on:

Electromagnetic radiation is generally divided into two classes: ionising and non-ionising.

Ionising radiation (gamma rays, x-rays and ultraviolet light) has enough energy to knock electrons off molecules, and is a known carcinogen.

Non-ionising radiation (visible and infrared light, microwaves and radio waves) carries less energy than needed to knock electrons off molecules, and in the past has been thought to affect biological tissue only by means of heating it. Hence many of the regulatory standards used around the world permit exposure of the public to non-ionising radiation up to limits based solely on intensities that cause tissue heating.

There is laboratory evidence that RF at power densities a tiny fraction of those permitted by official guidelines causes

These are some mechanisms by which RF exposure might cause any number of disease states, including cancer.

Worryingly, there seems to be no lower limit on the amount of RF that can cause harm. Exposure of quail eggs to 900 MHz (0.9 GHz) RF at doses as low as 0.0025 watts per square meter (cf ICNIRP’s guideline of 10 watts per square meter) causes significant oxidative stress—overproduction of free radicals/reactive oxygen species—and oxidative damage to DNA.

Statistically speaking, papers funded by the wireless industry are twice as likely as papers not funded by the wireless industry to report no harmful effects of radio frequencies.

Given that oxidative stress is common for many types of cancer cells that are linked with altered redox regulation of cellular signalling pathways and has also been linked to artherosclerosis, Alzheimer’s disease, arthritis and diabetes, there would seem to be significant reason for concern about allowing the public to be routinely exposed to 4,000 times the level of RF known to cause oxidative stress (10 W/m2 = 4,000 times 0.0025 Watts/m2).

Is it safe to use a cell phone?

There are several studies trying to determine the safety of cell phone use. Estimating emissions is not as straightforward as it seems: measurements made by the French Government in 2015 showed that 90% of the hundreds of phones tested emitted significantly more than the RF figures claimed by the manufacturer.

What can you do to limit or block radiation exposure from wireless devices?

How far away should you be from a WiFi router?

It is safe to sleep next to a wireless router? I would not sleep within 20 feet of any wireless router. Although it produces radio waves that, unlike X-rays or gamma rays, do not break chemical bonds or cause ionisation in humans, levels of concern are commonly observed when closer than 15 to 20 feet to a WiFi router.
