Of course they’re not. But they are banning wireless communication in nursery schools, because that’s new and parents aren’t entirely sure about what makes it work. Parents are, quite rightly, very worried about how any new thing will affect their children. Some things, like the effect of texting using proper grammar or how more screen time affects attention spans, are difficult to measure and we don’t really know how people will be when they grow up. But Wi-Fi as a cause of cancer or even headaches? We can test for that. We have tested for that. It’s fine.
The present study aimed to investigate the effects of chronic low-intensity microwave exposure (900, 1800 or 2450 MHz for 180 days) on cognitive function, heat shock protein 70 (HSP70), and DNA damage in the rat brain. The results showed declined cognitive function, elevated HSP70 level, and DNA damage in the brain of microwave-exposed animals. The results indicated that, chronic low-intensity microwave exposure in the frequency range of 900 to 2450 MHz may cause hazardous effects on the brain.
If you think your heart races when surrounded by wireless networks or 3G or LTE cell phones, it may not be in your head. A study involving 69 subjects reported that many of them experienced a real physical response to electromagnetic frequencies. Exactly what was the physical response? Increased heart rate — similar to the heart rate of an individual under stress. 
There is an alternative approach, rooted in what some scientists and ethicists call the “precautionary principle,” which holds that society doesn’t need absolute proof of hazard to place limits on a given technology. If the evidence is sufficiently solid and the risks sufficiently great, the precautionary principle calls for delaying the deployment of that technology until further research clarifies its impacts. The scientists’ petition discussed earlier urges government regulators to apply the precautionary principle to 5G technology. Current safety guidelines “protect industry—not health,” contends the petition, which “recommend[s] a moratorium on the roll-out of [5G]…until potential hazards for human health and the environment have been fully investigated by scientists independent from industry.”54
Wifi routers can and have still been able to emit frequencies even while turned off. So just, beware of that. I completely got rid of my wifi router at home. It’s to that point. Also save on the cable bill now so it’s a win win. Nope. Don’t need all that radiation just to have a “stronger” Internet connection for all my wireless devices! Haha, so u know what they did? The cable company cut off some channels that were in my package. To try and make me call back and pay to have extra channels. That’s why they ask you, what channels do you watch ? Try try to up sell sell sell you to get you to watch TV all day while your body is getting radiated all day from your wifi. Wether your hyper sensitive to it or not, like some of us are greatly effected, your health is still being effected.
The present study aimed to investigate the protective effects of melatonin against oxidative stress-mediated testicular impairment due to long-term exposure (2 h/day for 45 days) of 2.45 GHz Microwave Radiation. Result shows that melatonin prevented oxidative damage biochemically by significant increase (p < 0.001) in the levels of testicular LDH-X, decreased (p < 0.001) levels of MDA and ROS in testis (p < 0.01). Meanwhile, it reversed the effects of MWs on XO, protein carbonyl content, sperm count, testosterone level and DNA fragmentation in testicular cells. These results concluded that the melatonin has strong antioxidative potential against MW induced oxidative stress mediated DNA damage in testicular cells.
People who say cell phones are not safe cite peer-reviewed studies showing an association between cell phone use and tumor growth, DNA damage, and decreased fertility. They say cancers take 20-30 years to develop and cell phone studies have monitored periods of 10 years or less. They highlight the International Agency for Research on Cancer’s classification of cell phone radiation as a possible carcinogen. Read more background...
Another place that you want to use your cell phone hands-free is in your vehicle. Driving and texting or driving and talking on a mobile device that you hold in one of your hands is dangerous and one of the leading causes of traffic accidents and deaths. However, there are times when it's necessary to use your cell phone while driving, such as when you're using a GPS app. For these times, a car-mounted mobile device holder is the answer. These attach to your vehicle's dash or windshield in several ways, including suction cups, magnets and double-sided adhesive tape. These devices allow you to rotate the cell phone so you can see it vertically and horizontally, and some make it so you can adjust the angle of sight.
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.
“There are 25,000 brain tumor cases in India’s Andhra Pradesh and Telangana states, and most of them are attributed to excessive use of cell phones, as per a recent medical survey”. Girish Kumar said that World Health Organization warned of increasing risk of cell phone brain tumor and cancer cases caused by the use of cell phones and location of cell towers in residential areas.
