Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U.S. and European standard thresholds. A computer simulation was designed to obtain laptop heat flux from SolidWorks flow simulation. Increase in body temperature due to heat flux was calculated, and antenna radiation was calculated using Computer Simulation Technology (CST) Microwave Studio software. Steady state temperature and specific absorption rate (SAR) distribution in user's body, and heat flux beneath the laptop, were obtained from simulations. The laptop in its high performance mode caused 420 (W/m2 ) peak two-dimensional heat flux beneath it. The cumulative effect of laptop in high performance mode and 1 W antenna radiation resulted in temperatures of 42.9, 38.1, and 37.2 °C in lap skin, scrotum, and testis, that is, 5.6, 2.1, and 1.4 °C increase in temperature, respectively. Also, 1 W antenna radiation caused 0.37 × 10-3 and 0.13 × 10-1.

If you are concerned about the possible health effects of radio wave radiation emitted by your cell phone, your options are simple and cheap. This kind of radiation is at its highest levels nearest the antenna. Also, not all cell phones are created equal. Sar Shield offers a useful radiation chart for cell phones that provides an accurate "Sar rating" for every cell phone model. It's important to realize that at these low radiation levels, if you keep the cell phone away from your head and body, you are perfectly safe. However, if you'd rather not use a headset, then there are plenty of resources to obtain a radiation shield for your phone.
According to a peer-reviewed Nov. 2008 study in the journal Epidemiology, exposure to cell phone radiation while in the womb "was associated with behavior difficulties such as emotional and hyperactivity problems around the age of school entry." [65] A Dec. 2010 study replicated those findings. [67] A peer-reviewed Mar. 15, 2012 study found that mice exposed to cell phone radiation in the womb "were hyperactive and had impaired memory" as adults. [66]
I’ve started to shut off my WIFI from midnight until about sundown the next day. The results have been astounding. I’ve been having serious joint aches and I’m not THAT old. Enough that it was hampering my quality of life. So I did an experiment. I turned off my WIFI router and took out the battery. Been doing this now for 2 days and I’m telling you I’m a new woman. I’m a little stiff getting out of bed in the morning but nothing like I was.
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.
Of course, trying to avoid radio wave exposure is more or less impossible if you live in modern society. Moskowitz advises keeping wireless devices away from your body and turning off wireless networks when they’re not in use. While any health risks are still theoretical, “I think trying to minimize exposure is the best advice at this point,” Moskowitz adds.
In response to public concern, the WHO established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz. They have stated that although extensive research has been conducted into possible health effects of exposure to many parts of the frequency spectrum, all reviews conducted so far have indicated that, as long as exposures are below the limits recommended in the ICNIRP (1998) EMF guidelines, which cover the full frequency range from 0–300 GHz, such exposures do not produce any known adverse health effect.[2] Stronger or more frequent exposures to EMF can be unhealthy, and in fact serve as the basis for electromagnetic weaponry.
2. The power, or heating effect, of the phone is only one of many possible factors impacting cell phone ‘safety.’ Certainly it is useful to know if your phone has a high SAR value, but exposures to the radiation from the cell phone at non-heating levels have been linked to many serious biological effects, and the SAR value is not capturing anything about these harmful non-thermal exposures.
In one type of study, called a case–control study, cell phone use is compared between people with these types of tumors and people without them. In another type of study, called a cohort study, a large group of people who do not have cancer at study entry is followed over time and the rate of these tumors in people who did and didn’t use cell phones is compared. Cancer incidence data can also be analyzed over time to see if the rates of brain tumors changed in large populations during the time that cell phone use increased dramatically. These studies have not shown clear evidence of a relationship between cell phone use and cancer. However, researchers have reported some statistically significant associations for certain subgroups of people.
The purpose of this investigation was to analyze the effects of chronic 2.45 GHz leakage microwave irradiation on thyroid hormones and behavior of male rats. Behavioral changes were found to be significantly changed from controls for immobilization, rearing and ambulation behavior. Changes in behavioral parameters are also correlated with the trend of changes, compared to control animals, in hormonal blood levels of T3 and T4. Researchers concluded that low energy microwave irradiation may be harmful as it is sufficient to alter the levels of thyroid hormones as well as the emotional reactivity of the irradiated compared to control animals.

Electromagnetic Fields (EMF) are invisible. You can’t see, touch, or feel them, but doesn’t mean they’re not there. As awareness about possible negative effects of wireless energy grows, curiosity simultaneously rises. More and more people ask me about how far they need to be and where the optimal placement is of their routers are for they’re health and safety.


I thought I was getting Alzheimers until I read this study. I also had insomnia. I couldn’t focus, concentrate or remember anything. My energy levels were tanked. I felt like I was turning into a vegetable. I was ready to leave the planet, I was getting So depressed… I immediately disabled the wifi and put 2 laptops on an ether net and EVERY SINGLE SYMPTOM CLEARED UP!!!
Lloyd is correct. I’ve worked in wireless equipment design for over 30 years, from 30kHz to 3GHz, milliwatts to many-watts. In the late 2000’s I personally set the safety standards for wireless charging (WPC’s “Qi” format) after lengthy research. Starting at 400MHz and above, DNA strands can be broken or inflicted with sequence translocation when the applied fields excite mechanical shake, twist, and compression resonances of the helixes. Those would be cancer-provoking damage. Below 300MHz I’m not aware of significant non-thermal biological effects, which explain how we’ve been “lucky” with AM/FM radio, walkie talkies, CB’s, shortwave, and VHF TV not harming people en masse.
39. Beware of cyberbullying. Cyberbullying is yet another reason to monitor your child’s smartphone usage including call and text message records. While your child may not always tell you when they’re being mistreated by a friend or acquaintance, seeing threatening or bullying messages on your child’s phone will allow you to address issues before they escalate to dangerous levels. “Cyber bullies, adults and children alike, harass others by sending threatening or rude texts to cell phones.” – What Are Some Cell Phone Safety Tips For Kids?, How Stuff Works; Twitter: @HowStuffWorks
You probably can’t get away from the effects of Wi-Fi. Even if you disconnect your own router – which probably would be very disruptive to your life – you are exposed to Wi-Fi at work, where you shop and in your neighborhood. You can protect yourself, though, with a range of effective and affordable products from SafeSpace. For more information, click here.
14. Clean your phone regularly. “Newsflash: Your phone is dirty. Like, really dirty. It’s crawling with germs and bacteria that can cause acne and even nasty rashes. And if you take your phone to the bathroom often, it could also be covered in fecal matter.” – Amanda Hawkins, 5 Ways Your Phone Is Ruining Your Skin, Good Housekeeping; Twitter @goodhousemag
By comparison, even a very powerful high-end Wi-Fi router only produces around 1 watt of microwave energy and, unlike the magnetron in a microwave oven, a Wi-Fi router radiates that minuscule 1 watt of power in a bubble-like-cloud around the router. In other words, if you wanted to heat up even a milliliter of water above room temperature using this energy, you’d be waiting…well, forever.

In the Lancet article outlining their considerations, that IARC states that epidemiological studies that follow humans who use WiFi and cell phones for a few years are not conclusive. However, rodent studies that follow the animals throughout their lifetime find that wireless radiation does cause cancer or worsen cancer prognosis. The same animal studies also observed other changes in the brain and blood brain barrier in animals that are exposed to the radiation.


Wireless internet (Wi-Fi) providers have become essential in our daily lives, as wireless technology is evolving at a dizzying pace. Although there are different frequency generators, one of the most commonly used Wi-Fi devices are 2.4GHz frequency generators. These devices are heavily used in all areas of life but the effect of radiofrequency (RF) radiation emission on users is generally ignored. Yet, an increasing share of the public expresses concern on this issue. Therefore, this study intends to respond to the growing public concern. The purpose of this study is to reveal whether long term exposure of 2.4GHz frequency RF radiation will cause DNA damage of different tissues such as brain, kidney, liver, and skin tissue and testicular tissues of rats.
We investigated the effect of olive leaves extract administration on glucose metabolism and oxidative response in liver and kidneys of rats exposed to 2.45 GHz radiofrequency radiation (1h/day for 21 days). This exposure was shown to induce a diabetes-like status and also decreased the activities of glutathione peroxidase, catalase, superoxide dismutase, and groups thiol amount in liver and kidneys. Olive leaves extract administration (100 mg/kg, ip) in RF-exposed rats prevented glucose metabolism disruption and restored the activities of GPx, CAT and SOD and thiol group amount in liver and kidneys and was able to bring down the elevated levels of MDA in liver but not in kidneys. Our investigations suggested that RF exposure induced a diabetes-like status through alteration of oxidative response, while olive leaves extract was able to correct glucose metabolism disorder by minimizing oxidative stress induced by RF in rat tissues.
We’re living in a wireless technology age, but there’s some evidence that exposure to electromagnetic radiation from cell phones and wireless devices could increase your risk of certain cancers and tumors. However, more research is needed. In the meantime, I recommend practicing the precautionary principle. Some great cell phone safety tips include:

Here we studied the influence of microwave irradiation at bands corresponding to wireless router (WLAN) and mobile devices (GSM) on leaf anatomy, essential oil content and volatile emissions in Petroselinum crispum, Apium graveolens and Anethum graveolens. Microwave irradiation resulted in thinner cell walls, smaller chloroplasts and mitochondria, and enhanced emissions of volatile compounds, in particular, monoterpenes and green leaf volatiles. There was a direct relationship between microwave-induced structural and chemical modifications of the three plant species studied. These data collectively demonstrate that human-generated microwave pollution can potentially constitute a stress to the plants.
DefenderShield Cellphone Radiation Case also claims independent testing and says in their website: That a "sophisticated layering of separate non-toxic, human safe materials processed for maximum radiation blocking efficiency. Each material has unique and targeted radiation-shielding characteristics designed to work in unison to eliminate all radiation emissions from 0 to 10 GHZ and Defender Shield technology refracts, conducts and finally absorbs all these potentially harmful emissions."  In this demonstration, the radiation level measured when DefendeShield case was on is still quite a bit above the level of exposure that I would recommend. I personally do not recommend-holding a phone with a shielding case to your head as the DefenderShield website shows a young woman doing as she demonstrates the product. 
was since I had Wi-Fi that it had started so turned it off and after a few days I had improved just to check I turned it back on and immediately I felt the effect and stared feeling ill. I no longer go to my sons as he lives in a block of flats with lots of signals also have avoid shops and areas with Wi-Fi cannot visit friends and family even church, I’ve had to put foil on my walls to reduce the neighbours signals, feel like a prisoner and can hardly go anywhere, really hard when needing doctors, dentist, hospital, council etc. I’m sick of it now there’s no need for so much and one day more people will suffer these affects.
I turn my router off every night before bedtime. If it gets left on by a kid, I can tell immediately when I wake up in the morning because I do not feel nearly as rested. I am certain that the router for my level of sensitivity acts like a stimulant. When it is on and I am trying to go to sleep I feel as if I have had a couple cups of coffee. If it has been left on all night, when I wake up I feel just the same as if I had drank coffee close to bedtime and did not sleep soundly.
A series of studies testing different scenarios (called simulations by the study authors) were carried out using incidence data from the Nordic countries to determine the likelihood of detecting various levels of risk as reported in studies of cell phone use and brain tumors between 1979 and 2008. The results were compatible with no increased risks from cell phones, as reported by most epidemiologic studies. The findings did suggest that the increase reported among the subset of heaviest regular users in the Interphone study could not be ruled out but was unlikely. The highly increased risks reported in the Swedish pooled analysis were strongly inconsistent with the observed glioma rates in the Nordic countries (24).
Recall bias, which can occur when data about prior habits and exposures are collected from study participants using questionnaires administered after diagnosis of a disease in some of the participants. It is possible that study participants who have brain tumors may remember their cell phone use differently from individuals without brain tumors. Many epidemiologic studies of cell phone use and brain cancer risk lack verifiable data about the total amount of cell phone use over time. In addition, people who develop a brain tumor may have a tendency to recall cell phone use mostly on the same side of the head where their tumor was found, regardless of whether they actually used their phone on that side of the head a lot or only a little.
We investigated the long-term effects of radiofrequency radiation (RFR) emitted from Wi-Fi systems on hearing. Sixteen Wistar albino rats were divided equally into two groups: sham control and exposure groups. The rats in the experimental group were exposed to 2.4 GHz RFR emitted from a Wi-Fi generator for 24 h/day for one year. The same procedure was applied to the rats in the sham group, except that the Wi-Fi generator was turned off. All groups were kept in Faraday cages during the 12 months to eliminate external electromagnetic fields. The distance between the Wi-Fi generator antenna and the exposure cages was 50 cm. Pre-exposure distortion product otoacoustic emissions (DPOAE) of all rats were measured at the beginning, 6th and 12th months of the study. The DPOAE values of the sham, baseline and exposure groups were compared statistically. For the 6000 Hz hearing frequency, the DPOAE values in the exposure group were lower than those in the sham group (p < 0.05). Similarly, the 6000 Hz hearing frequency values obtained at the end of the 12th month were also lower than the baseline and 6-month values in the exposure group (p < 0.05). In contrast, the DPOAE values at the 6th and 12th months of exposure for the 2000 Hz hearing frequency were higher than the baseline value (p < 0.05). These results indicated that 12 months of RFR (24 h/day) at 50 cm from a 2.4 GHz Wi-Fi source can affect hearing. However, further studies are necessary.
RF Safe methodologies for shielding the cell phone radiation only use technologies to deflect radiation which is directed towards the user’s body and will not cause the phone to increase output power. RF Safe’s technical goal is only blocking RF radiation that your body would have absorbed (line-of-sight radiation, in relationship to the device itself and your body) — radiation absorbed into your body wasn’t helping the cell tower connection or your health either. Keeping this in mind, only the front shielded part of the phone should be facing your body at all times.
Sexting: The vast majority of kids are smart and don’t take, send, or post or even store nude photos of themselves or peers on their phones. People who do so can be charged with production, distribution, or possession of child pornography, a serious crime. They can also be subjected to jokes, bullying, blackmail, expulsion from school, loss of a job, etc. and the images can circulate forever. Just don’t go there.

Result: More than 100 studies on 2.45 GHz radiation were analyzed, most of which found changes compared to the control groups at levels below the safety guidelines of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) (issued as exposure limits of the 26th Federal Pollution Control Ordinance (BImSchV) in Germany). The available studies document damage to the reproductive system, impacts on the EEG and brain functions, as well as effects on the heart, liver, thyroid, gene expression, cell cycle, cell membranes, bacteria, and plants. As a mechanism of action, many studies identify oxidative stress. Adverse effects on learning, memory, attention, and behavior are the result of cytotoxic effects.
This is extremely controversial but we can’t ignore that plenty of animal models indicate that exposure to electromagnetic radiation increases the risk of tumor development. While human studies are rare, reports and case studies abound. One such case involves a young 21-year-old woman who developed breast cancer. What makes this case unique was that her family did not have a predisposition to breast cancer… and she developed the tumor right on the spot she carried her cell phone in her bra. [15]
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.

Want an official word on the matter? The World Health Organization, which tends to err on the side of caution before outright dismissing something as toxic, carcinogenic, or otherwise harmful, is very clear that there is no health risk from radio-frequency communication devices. (Their briefing on the matter is actually a great read that highlights how low the risk is and how even people in Wi-Fi dense locations like schools and hospitals are exposed to radio-frequency radiation at thousands of times lower than international safety standards designed to protect individuals working in related industries).

A method of simulating thermal mapping of positioning laptop on laps of an adult man was developed. To tackle this problem, we exploited computer simulation and, to make the simulation close to the actual problem, we created 3D models of an actual laptop (Sony FW 590 Gab), antennas, and human phantom with inhomogeneous body, large number of tissues, and dispersion properties. We employed a commercial laptop Wi-Fi antenna at 2.4 GHz and a dipole antenna at 5 GHz, thermal sources with radiation powers, and human body voxel consisting of 97 tissues which were described previously. In the simulation, maximum SAR in human body was calculated 0.37 × 10−3 and 0.13 × 10−1 (W/kg) at 2.4 and 5 GHz, respectively, which was negligible according to IEEE standards; thus, the major calculated temperature elevation was due to laptop thermal sources. The temperature in glans penis, lap skin, lap muscles, and testes increased up to 37.8, 42.9, 38.8, and 37.2 °C, respectively, which was in line with clinical studies of thermal effect. Hence, the proposed method can be replicated for other scenarios. It is worth noting that the presented result cannot be easily generalized to other devices or human models. However, the whole method is replicable for similar phenomena. The recommended subject for future works can be used with the presented method for determining the effect of laptop and other devices on adult pregnant women and similar cases.
25. Use your cell phone for emergencies or important calls only. “Turn your cell phone off more often. Reserve it for emergencies or important matters. As long as your cell phone is on, it emits radiation intermittently, even when you are not actually making a call. If you’re pregnant, avoiding or reducing your cell phone use may be especially important.” – Dr. Mercola, NEW Urgent Warning to All Cell Phone Users, Mercola.com; Twitter: @mercola
