Wi-Fi is convenient but many have raised doubts concerning the safety of unseen forces that permeate everything around us. Since the introduction of Wi-Fi in 1997, researchers have performed dozens of studies to explore the subject. The results are clear and shocking — Wifi can negatively affect overall health and brain health, especially in children.

The highest typical daily exposure, according to a study of 2009, came from cellphone base stations, cellphones and DECT cordless phones, with the highest exposure locations in trains, airports and buses.[17] The typical background power of electromagnetic fields in the home can vary from zero to 5 milliwatts per meter squared.[citation needed] Long-term effects of these electromagnetic fields on human and animal health are still unknown.


Anything you can do to keep the phone away from your head will help. (Even cell phone manufacturers warn consumers about this. See the previous post Cell Phone Manual Warnings for examples of warnings from Samsung, Apple and more.) If you hold the phone 2 inches away, the signal is about one-fourth the original strength. At four inches away, it’s about 1/16th as strong. Even better is a hands-free kit with a wireless air tube nearest the earpiece. (A regular wired headset can act as an antenna and make matters worse.)
An Oct. 20, 2011 study of 358,403 Danish citizens – the largest study of its kind to date – concluded that "there was no association between tumors of the central nervous system or brain and long term (10 years +) use of mobile phones." [39] A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents. [50] Numerous other studies published from 2001-2013 have similarly concluded that there is no association between cell phone use and the development of brain tumors. [1] [41] [42] [45] [46] [49]
In the current study, the pattern of the response of E coli to Wi-Fi and RF simulator radiation was identical. The maximum differences in the diameters of inhibition zones were observed between 6 and 9 hours of the bacterial exposure to radiation (Figures 1 and 2). After 12 hours of exposure, the bacterial responses to radiation as a stressor led to returning to the preexposure status.

Finally, if my phone is NOT in airplane mode… and I turn it off, are the RF signals still going?? I was thinking that turning the phone off is not enough.. you must have it in airplane mode (when phone is off or on) for the RF signals to stop. But #5 says “Make it a habit to either switch to flight mode or turn it off altogether when not in use.” Thanks for clarifying this; I am not a techie, so I just don’t know…


A 2012 study by NCI researchers (25) compared observed glioma incidence rates in U.S. SEER data with rates simulated from the small risks reported in the Interphone study (6) and the greatly increased risk of brain cancer among cell phone users reported in the Swedish pooled analysis (19). The authors concluded that overall, the incidence rates of glioma in the United States did not increase over the study period. They noted that the US rates could be consistent with the small increased risk seen among the subset of heaviest users in the Interphone study. The observed incidence trends were inconsistent with the high risks reported in the Swedish pooled study. These findings suggest that the increased risks observed in the Swedish study are not reflected in U.S. incidence trends.
The easiest thing for you to do is to put a passcode on your phone. Having a passcode will make it harder for someone to pick up your phone to scroll through, access your accounts, or install something malicious. In the event that your phone gets stolen or you lose it, it’ll make it a bit harder for others to get into your phone. Most phones just ask for a 4-digit passcode, but some phones will allow you to use a more complex passcode.

Moving the meter around the case, we detect readings on the side, back and front of the case. We use the multi-directional TES 593 meter which measures 10 MHz to 8GHz. We use the unit of micro-watts per square centimeter, which looks like this little symbol: μW/cm² and we use it on the max setting which shows the maximum measured value. In non-science speak: the highest level of RF we see, which could be from the back the side or the front. 


Users of wireless devices are typically exposed for much longer periods than for mobile phones and the strength of wireless devices is not significantly less. Whereas a Universal Mobile Telecommunications System (UMTS) mobile phone can range from 21 dBm (125 mW) for Power Class 4 to 33 dBm (2W) for Power class 1, a wireless router can range from a typical 15 dBm (30 mW) strength to 27 dBm (500 mW) on the high end.[6]
An analysis of data from all 13 countries participating in the Interphone study reported a statistically significant association between intracranial distribution of tumors within the brain and self-reported location of the phone (7). However, the authors of this study noted that it is not possible to draw firm conclusions about cause and effect based on their findings.
We do have evidence that cellphones (or WiFi) do NOT cause an increase in brain tumors. Look at the time period over which cellphone use became common -- say, over the last twenty years. During that time, the incidence of brain tumors has remained absolutely flat. With over four billion people using cellphones (or WiFi) today, if there was any influence on the development of brain tumors, we would be seeing that by now.

40. Set clear rules and guidelines for downloading media and apps. Giving your kids free reign to use all the features on their smartphones can quickly rack up your wireless bill and introduce security risks to their devices. “Downloading new ringtones or games can add unwanted expenses or hidden bugs. Set limits and rules about downloads.” – Amanda Martin, Cell Phone Safety Tips for your Child, Securemama.com; Twitter: @securemama
Researchers at Wageningen University in the Netherlands have reported that radiation from WiFi networks is harmful to trees. Problems observed included growth variations, and bleeding and fissures in tree bark. The researchers exposed 20 ash trees to various sources of radiation for three months. The tress closest to the WiFi source exhibited a lead-like shine on the leaves. The researchers also found that WiFi radiation is harmful to growing corn.

METHODS: Standard class V cavities were prepared on the buccal surfaces of 20 non-carious extracted human premolars. The teeth were randomly divided into 2 groups (n = 10). The control group was stored in non-environment. The specimens in the experimental groups were exposed to a radiofrequency radiation emitted from standard Wi Fi devices at 2.4 GHz for 20 min. The distance between the Wi-Fi router and samples was 30 cm and the router was exchanging data with a laptop computer that was placed 20 m away from the router. The concentration of mercury in the artificial saliva in the groups was evaluated by using a cold-vapor atomic absorption Mercury Analyzer System. The independent t test was used to evaluate any significant differences in mercury release between the two groups.
Since children’s skulls are thinner than adults’ and their nervous systems are still developing, researchers believe they may be at a greater risk for cell phone-related cancers. They’ll also be exposed to the potentially harmful radiation significantly longer than their parents’ generation. Until more is known about the possible carcinogenic effects of cell phone use, curb your kids’ cell phone habits by encouraging texting or using a landline instead—if they can actually recognize a landline anymore, that is.
For adults and children alike, the process by which wireless radiation may cause cancer remains uncertain, but it is thought to be indirect. Wireless radiation has been shown to damage the blood-brain barrier, a vital defense mechanism that shields the brain from carcinogenic chemicals elsewhere in the body (resulting, for example, from secondhand cigarette smoke). Wireless radiation has also been shown to interfere with DNA replication, a proven progenitor of cancer. In each of these cases, the risks are higher for children: Their skulls, being smaller, absorb more radiation than adults’ skulls do, while children’s longer life span increases their cumulative exposure.29
RESULTS: The results revealed that long-term exposure of 2.4 GHz Wi-Fi radiation can alter expression of some of the miRNAs such as miR-106b-5p (adj p* = 0.010) and miR-107 (adj p* = 0.005). We observed that mir 107 expression is 3.3 times and miR- 106b-5p expression is 3.65 times lower in the exposure group than in the control group. However, miR-9-5p, miR-29a-3p and miR-125a-3p levels in brain were not altered.
BACKGROUND: The use of devices emitted microwave radiation such as mobile phones, wireless fidelity (Wi-Fi) routers, etc. is increased rapidly. It has caused a great concern; the researchers should identify its effects on people's health. We evaluated the protective role of Vitamin C on the metabolic and enzymatic activities of the liver after exposure to Wi-Fi routers.
Anti-radiation or radiation blocking or phone shield cases. Do they Work? SafeSleeve, DefenderShield, Vest, Alara, Pong, Reach and ShieldMe  and other EMF protection phone cases claim to block the radiation from your cellphone or smartphone. Anti-radiation cellphone case brands make enticing claims like this: ". . .eliminate up to 99% of the harmful radiation coming from the phone!"

The aim of the present study was to investigate the effect of 2.45-GHz electromagnetic radiation (60min/day for 4 weeks) on the oxidant and antioxidant status of skin and to examine the possible protective effects of β-glucans (50 mg/kg/day before each EMR exposure) against the oxidative injury in male rats. EMR exposure caused a significant increase in malondialdehyde levels and catalase activity, while the activities of superoxide dismutase and glutathione peroxidase decreased in skin tissues. Systemic β-glucan significantly reversed the elevation of MDA levels and the reduction of SOD activities. β-glucan treatment also slightly enhanced the activity of CAT and prevented the depletion of GSH-Px activity caused by EMR, but not statistically significantly. The present study demonstrated the role of oxidative mechanisms in EMR-induced skin tissue damages and that β-glucan could ameliorate oxidative skin injury via its antioxidant properties.
31. Read the fine print. “Buried in cell phone manuals, cell phone companies specifically instruct us that phones should not be held close to the body. For example, the iPhone 5 manual states “Carry iPhone at least 10mm away from your body to ensure exposure levels remain at or below the as—tested levels. Cases with metal parts may change the RF performance of the device, including its compliance with RF exposure guidelines, in a manner that has not been tested or certified.” The Blackberry Bold states, “keep the BlackBerry device at least 0.59 in. (15 mm) from your body (including the abdomen of pregnant women and the lower abdomen of teenagers) when the BlackBerry device is turned on and connected to the wireless network.
43. Search for the unknown callers. Discovering unknown or anonymous numbers on your child’s phone can be alarming, but a bit of detective work can lead you to answers. “Now that you know who your kid chats with, you can see if there are any messages that make you suspicious. If you spot a phone number you don’t recognize, do a reverse phone lookup to discover exactly who they are talking to. By searching any domestic number, you may discover the texter’s name, carrier, and address.
As a result, it is observed that the long-term exposure to Wi-Fi 2.4 GHz Radiofrequency radiation caused an increase in the DNA damage of the brain, liver, kidney, and skin tissue of rats, but this increase was not significant. Therefore it is determined that the long-term exposure to Wi-Fi 2.4 GHz Radiofrequency radiation does not cause the DNA damage of the brain, liver, kidney, and skin tissue of the rats. However it is concluded that the long-term usage of 2.4 GHz Radiofrequency wireless internet providers could cause a potential risk of DNA damage in the testes.

Supermarkets or plant nurseries (plants); WiFi hotspots are available in many homes and commercial establishments. If the student does not have a wireless device that displays WiFi signal strength, an inexpensive standalone wireless signal detector may be purchased on the Internet. Plant lights may be purchased on the Internet and at garden supply stores.


Influence of environmental stress factors on both crop and wild plants of nutritional value is an important research topic. The past research has focused on rising temperatures, drought, soil salinity and toxicity, but the potential effects of increased environmental contamination by human-generated electromagnetic radiation on plants have little been studied.
MATERIALS AND METHODS: Adult male Sprague-Dawley rats in the weight range of 230 to 260 g were divided into control, sham, Wi-Fi exposed groups. After long term exposure (4 h/day for 45 days) to Wi-Fi electromagnetic radiation, plasma levels of glucose and insulin during intraperitoneal glucose tolerance test were measured. Islet insulin secretion and content, lipid peroxidation and antioxidant status in pancreas of rats were determined.
Consider parental-control tools. There are actually two major types of parental controls. The first is family rules or guidelines that you establish with your children, and the second is technology tools provided by cellphone companies, smartphone makers and app developers. If you do use technology to monitor or limit your child’s phone activities, in most cases it’s a good idea to be up front with them and revisit it every now and then as they mature.

The word radiation is, to the lay person, a scary word. Radiation is the stuff that 1960s school children were taught to climb under their desks to avoid, and what prompted Cold-War-terrified Americans to build backyard bomb shelters. Radiation is the stuff that leads meltdowns at nuclear power plants to contaminate the ocean and make land uninhabitable for hundreds of years.
We aimed to investigate the effects of distance from sources on calcium signaling, cytosolic ROS production, cell viability, apoptosis, plus caspase-3 and -9 values induced by mobile phones and Wi-Fi in breast cancer cells. The cytosolic ROS production, Ca2+ concentrations, apoptosis, caspase-3 and caspase-9 values were higher in groups exposed to 900 MHz, 1800 MHz and 2450 MHz compared to controls at 0 cm, 1 cm and 5 cm distances although cell viability (MTT) values were increased by the distances. There was no statistically significant difference in the values between control, 20 and 25 cm. Wi-Fi and mobile phone EMR placed within 10 cm of the cells induced excessive oxidative responses and apoptosis via TRPV1-induced cytosolic Ca2+ accumulation in the cancer cells. Using cell phones and Wi-Fi sources which are farther away than 10 cm may provide useful protection against oxidative stress, apoptosis and overload of intracellular Ca2+.

Responsibility for driver cell phone safety is the part of so many distinct factions. Consumer safety advocates oppose telecommunications lobbyists, and state lawmakers seem to avoid the larger issue of driver distractions. But without all participants it’s likely that the cell phone safety debate would lose the thrust required to effect real change. And there will be change.

Central to keeping the scientific argument going is making it appear that not all scientists agree. Again like the tobacco and fossil-fuel industries, the wireless industry has “war gamed” science, as a Motorola internal memo in 1994 phrased it. War-gaming science involves playing offense as well as defense: funding studies friendly to the industry while attacking studies that raise questions; placing industry-friendly experts on advisory bodies like the World Health Organization; and seeking to discredit scientists whose views depart from the industry’s.21
“In addition to protecting your phone from scratches and breaks, a basic case can help conceal a distinctive phone’s telltale markings. That’s a detriment if you’re trying to show off your handset’s badass styling, but a benefit for maintaining a lower profile. Note: Even though they look better, a flashy designer case is like sticking a “steal me” marquee on your phone.” – Jessica Dolcourt, Keep Your Phone from Getting Stolen (and What to Do If It Is), CNET; Twitter: @CNET
