Foster was Moulder’s coauthor on that 2013 review of Wi-Fi’s health effects. He says that, based on our current understanding of radio wave strengths and risks, world health authorities have set safety standards for all devices and appliances that emit electromagnetic radiation—from phones and microwaves to your car’s keyless entry fob. “The exposure you get from your Wi-Fi router is orders and orders of magnitude below those safety limits,” he explains.
Wireless internet (Wi-Fi) electromagnetic waves (2.45 GHz) have widespread usage almost everywhere, especially in our homes. Considering the recent reports about some hazardous effects of Wi-Fi signals on the nervous system, this study aimed to investigate the effect of 2.4 GHz Wi-Fi radiation on multisensory integration in rats. This experimental study was done on 80 male Wistar rats that were allocated into exposure and sham groups. Wi-Fi exposure to 2.4 GHz microwaves [in Service Set Identifier mode (23.6 dBm and 3% for power and duty cycle, respectively)] was done for 30 days (12 h/day). Cross-modal visual-tactile object recognition (CMOR) task was performed by four variations of spontaneous object recognition (SOR) test including standard SOR, tactile SOR, visual SOR, and CMOR tests. A discrimination ratio was calculated to assess the preference of animal to the novel object. The expression levels of M1 and GAT1 mRNA in the hippocampus were assessed by quantitative real-time RT-PCR. Results demonstrated that rats in Wi-Fi exposure groups could not discriminate significantly between the novel and familiar objects in any of the standard SOR, tactile SOR, visual SOR, and CMOR tests. The expression of M1 receptors increased following Wi-Fi exposure. In conclusion, results of this study showed that chronic exposure to Wi-Fi electromagnetic waves might impair both unimodal and cross-modal encoding of information.
This is an animal experimental study, which was conducted in the Department of Anatomical Sciences, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, IRAN, from June to August 2014. Three-month-old male Wistar rats (n=27) were exposed to the 2.45 GHz radiation in a chamber with two Wi-Fi antennas on opposite walls. Animals were divided into the three following groups: I. control group (n=9) including healthy animals without any exposure to the antenna, II. 1-hour group (n=9) exposed to the 2.45 GHz Wi-Fi radiation for 1 hour per day during two months and III.7-hour group (n=9) exposed to the 2.45 GHz Wi-Fi radiation for 7 hours per day during 2 months. Sperm parameters, caspase-3 concentrations, histomorphometric changes of testis in addition to the apoptotic indexes were evaluated in the exposed and control animals.
"To expect relief from radiation exposure from one specific device, is nearly impossible. It’s crucial to weigh in the MANY environmental factors; such as, temperature, atmospheric pressure, other radio waves, emissions from other devices, energy shifts from others around you, and Schumann Resonance shifts. Therefore," he explains that “relying on alteration of the environment as a safety precaution is always a game of chance…and signals affect people differently,” which adds another variables in the game of chance.
Lloyd’s precautions are good ones, although he doesn’t cover cell phone use. I’ve worked on cellular telephony for the last 18 years, coming to the same conclusions about cell phones about ten years ago, the science had gotten conclusive enough for me, as I doubted at first that they could be a problem. As you may have heard, you don’t want to talk on them next to your head if you can help it, use speakerphone mode or wired or Bluetooth headset (BT is very low power, usually keeping itself around only a milliwatt, although wired or speakerphone is better). Don’t park it all day long on any body parts you want to keep cancer-free, especially the pelvic and pectoral regions (trying to keep it classy here). I wouldn’t advise living within a third of a mile of a cell phone tower, or within a mile of a TV tower, if you can help it. Best wishes all.
It should be noted that the given values of SAR were normalized to 1 W peak antenna power output, while typically a WLAN antenna radiates about 10 mW; therefore, for a real world operating system, maximum SAR of 0.37 × 10−3 and 0.18 × 10−3 (W/kg) is expected for 2 and 1 active antennas, respectively, which are 104 times lower than the European safety limit (2 W/kg) [IEEE Standard for Safety Levels with Respect to Humans, 2005].
Long-term exposure to Radio Frequency waves or microwave radiation has long been studied and shown to produce all sorts of adverse health effects. See my post on EMF Radiation Exposure Symptoms for a full list of common symptoms. Even the American Cancer Society, who in large part will not fully say that EMF radiation causes long-term harm, and instead errs on the side of not enough research, admits on their website, that:
c) and before you raise the argument that visible light is itself electromagnetic radiation, with even shorter wavelengths than microwaves, electromagnetic radiation within the visible light range does not penetrate living cells and other molecular materials as X-Rays (ionising radiation) or microwaves (non-ioninsing radiation) do. Practically all visible light is reflected by our bodies, and therefore it’s energy is not absorbed by our cells and is therefore harmless.
The possible effects of RF-EMR due to cellular phone and Wi-Fi usage should be investigated by researchers in more detail because the harmful effects should be proven instead of just implying the possible detrimental effects. Our findings display contrast results when we compared them with existing information and beliefs. We have not seen any difference between sperm parameters and cell phone and wireless internet usage. Larger population based studies combined with the laboratory results are needed to reach a definitive conclusion.
37. Be careful when sharing your phone number. Teenagers may be so excited to finally have their own cell phone or smartphone that they immediately give out their number to everyone they know – or worse, publish it online on their social media profiles. “Only give out your phone number to people you know for sure you can trust.” – Sameer Hinduja, Ph.D. and Justin W.

SafeSleeve's report is right up front about showing that they do not test or certify the Safe Sleeve case, rather they are simply testing the material they put into the case in a completely artificial environment, in a laboratory setting, using a signal generator and a power amplifier. Safe Sleeve includes photos showing how the measurements are taken. But that may not be how anyone will ever use their phone.

There was no significant difference between sperm counts and sperm morphology excluding sperm motility, due to mobile phone usage period, (p = 0.074, p = 0.909, and p = 0.05, respectively). The total motile sperm count and the progressive motile sperm count decreased due to the increase of internet usage (p = 0.032 and p = 0.033, respectively). In line with the total motile sperm count, progressive motile sperm count also decreased with wireless internet usage compared with the wired internet connection usage (p = 0.009 and p = 0.018, respectively). There was a negative correlation between wireless internet usage duration and the total sperm count (r = −0.089, p = 0.039).
You know what’s equally as concerning? Even though we don’t fully understand the impacts of long-term wireless radiation, we’re forging ahead with 5G wireless technology. Within a few years, this technology could mean millions of mini cell towers could pop up on street corners, according to the Federal Communications Commission chairman. (3) Developing a 5G network is moving forward despite the fact that we don’t even remotely understand 5G health effects.
In response, we would state that all wireless frequencies currently used by the public are categorized as radiofrequency radiation. People have not been using Wi-Fi for as long as they have been using cell phones, so the research that has looked at long term use of cell phones is very important in considering the long term health risks from wireless and Wi-Fi specifically.
The objective of this study was to investigate effects of 2.437 GHz radiofrequency radiation (24h/day for 20 weeks) emitted from indoor Wi-Fi Internet access devices on rat testes using histological and immunohistochemical methods. Researchers observed significant increases in serum 8-hydroxy-2′-deoxyguanosine levels and 8-hydroxyguanosine staining in the testes of the experimental group indicating DNA damage due to exposure (p < 0.05) as well as decreased levels of catalase and glutathione peroxidase activity in the experimental group, which may have been due to radiofrequency effects on enzyme activity (p < 0.05). These findings raise questions about the safety of radiofrequency exposure from Wi-Fi Internet access devices for growing organisms of reproductive age, with a potential effect on both fertility and the integrity of germ cells.
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
It’s also packing a decent camera, so your kid can share selfies without worrying about the quality. It’s not perfect, and the battery life might not last as long as you’d like — but Motorola’s TurboPower charging means 15 minutes of charging can give six hours of battery life. Sit your kid down to dinner and plug their phone in, and it should be more than ready to see them through to bedtime. All in all, the Moto G6 is an extremely solid phone that should serve your child well.
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.
Non-ionizing radiation at 2.45 GHz may modify the morphology and expression of genes that codify heat shock proteins (HSP) in the thyroid gland. The present study used a diathermy model – the therapeutic application of non-ionizing radiation – on laboratory rats subjected to maximum exposure non-ionizing radiation (30 min, 10 times in two weeks) in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue.Ninety minutes after radiation with the highest SAR, the central and peripheral follicles presented increased size and the thickness of the peripheral septa had decreased. Twenty-four hours after radiation, only peripheral follicles radiated at 12 W were found to be smaller. Morphological changes in the thyroid tissue may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic-pituitary-thyroid axis.
You are being trolled people. This article is so obviously not correct. All of the examples given are so subjective and there are hints in there that they are having a laugh at you for believing this. “When a group of Danish ninth graders experienced difficulty concentrating after sleeping” Come on, really? It wasn’t because they were playing games or chatting to their friends that their minds were too stimulated to sleep straight away?
Studies have shown an association between cell phone use and a decreased risk of certain brain tumors. According to a peer-reviewed Dec. 2006 study of 420,095 cell phone users in Denmark, the results showed a "reduced brain tumor risk" among long-term subscribers.  Two other peer-reviewed studies also found that cell phone users had a slightly decreased risk of developing brain tumors. A July 20, 2005 Danish study  found a "decreased risk for high-grade glioma," a malignant brain tumor, and a 2005 Swedish study  also found a "decreased odds ratio" for developing glioma as well as meningioma, another type of brain tumor.
*The ability to browse the internet (for tweens and teens that have access to the internet on their cell phone) opens up an entirely new area of safety concerns. Not only can kids search the web more discreetly, most parents do not view this activity as of much of a risk as they do allowing their kids to search on a regular computer. The fact is, the dangers are just as real and even worse when you consider that with a smart phone, kids can search the internet outside of the watchful eye of parents while using their cell phone in school.
Conclusions: Based on the extensive body of research and the adverse health effects demonstrated in the majority of the studies, it is recommended that steps should be taken to minimize RF radiation exposure in accordance with official recommendations. Wired solutions should be given preference. Current exposure limits and SAR values do not protect from health risks associated with Wi-Fi radiation. The adverse effects on learning, attention, and behavior serve as a basis for educational institutions of all age groups to forgo the use of Wi-Fi applications. Due to cytotoxic effects, Wi-Fi technologies are not suitable for hospitals and telemedicine. Wi-Fi technologies should not be used in bedrooms, work spaces, common lounges, hospital rooms, lecture halls, classrooms, and public transport. The possible risks associated with Wi-Fi radiation could be avoided by testing alternative technologies at other frequency bands like optical VLC/Li-Fi technologies (visible light communication). When Wi-Fi cannot be avoided as a transition solution, the ALARA principle must be applied: no continuous transmission, instead Wi-Fi networks that can be turned off and feature dynamic power management.
“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.
