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.
As with exposure to ‘anything’ sun, pollen, pharmaceuticals, there will be a certain percent of population that is ‘sensitive or hypersensitive’ to wifi / emf frequency. I am definitely sensitive with my husband doing his own control experiment by holding his wifi phone behind by head without my knowledge and me In pain from a piercing wave going through my head. Why is it that it must be all or nothing. There are those who will never be sick from wifi/ emf and those of us who live with it everyday.
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.
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.

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.
Five properties of non-thermal EMF effects are discussed. These are that pulsed EMFs are, in most cases, more active than are non-pulsed EMFs; artificial EMFs are polarized and such polarized EMFs are much more active than non-polarized EMFs; dose-response curves are non-linear and non-monotone; EMF effects are often cumulative; and EMFs may impact young people more than adults.

As our video points out: Measurements will vary with signal strength and other factors and that includes ambient energy. I talk about ambient energy in a lot of my videos-it's the energy that's in whatever environment I happen to be measuring in that's coming from a source of wireless energy that isn't the subject of what I'm measuring. My home is not a lab of course, but fortunately it's always measured very low for RF radiation.
To date, there are a few long-term studies, very few in humans and even fewer epidemiological studies, apart from the studies on laptops with small numbers of study subjects. It is also far too early to generate reliable figures at this time. However, there are indications that especially newborns, children, or adolescents are particularly vulnerable as has been presented in detail by the research teams of Nazırogˇ lu, Atasoy, Margaritis/ Panagopoulos, Orendacˇ ova, Othmann, Ozorak, Sangun, Shahin and Yuksel. The experiments were carried out with rats or mice, in some cases as long-term studies (up to 1 year). In this context, it is important to note that rats and mice used in laboratories have a life expectancy of perhaps two years. This at least allows us to infer that human children and adolescents have to be protected from possible increased risks. In the study of Margaritis et al. (2014), the authors point out that the exposure levels from Bluetooth (0.3 V/m) and Wi-Fi routers (here 2.1 V/m) showed greater effects than cell phone radiation sources with much higher field strengths. This may coincide with the findings of the papers by von Klitzing, which stated that the power-dependent pulse of 10 Hz (1 ms) from Wi-Fi routers triggered reactions. Kumari et al. observed in a study from 2012 that higher levels of ROS in the liver suppress antioxidant enzymes and that lower levels cause an increase. This could be a key to further mechanisms as to how or whether tissue damage occurs or perhaps not. Likewise, the polarization of RF radiation (Meena et al. 2014, Panagopoulos et al. 2015) should also receive additional attention.

50. Model the behavior you want to see from your child. “Model the manners and behavior you want to see. Avoid texting in the car. Consider narrating your phone use (“I’m looking up directions to the party”) so young kids understand the utility of the device.

"S8 Good...Love it...Dropped it a few times no cracks with rhis case so far, cool leds tell time or do a little dance of music whenever you do close it, it saves my battery as well because ir prevenrs the screen from turning on when rhe case is on which prevents always on display...It's a great case, the led notifications and functions are handy, it protects the phone really well; the problem is that we bought Dex and having to remove the case to be able to use Dex with my phone is a bummer; if not this will be a 5 stars review."
In 2015, scientists from around the world united for the International EMF Scientist Appeal based on the results of over 2,000 research papers. The appeal is the collective voice of 190 scientists from 39 different countries. They are calling for tighter regulations and more security measures when dealing with electromagnetic field exposures generally, and WiFi in particular.
Like cell phones, routers use radio frequency (RF) energy—a form of electromagnetic radiation—to bring wireless internet to your computer, TV, and other devices. Bluetooth headphones and speakers also rely on RF signals to play music. Smartwatches use RF to connect to your phone. And any WiFi-connected smart devices in your home also receive and transmit data using this type of energy. Do you need to worry about any of that?
Niels Kuster, a Swiss engineer, initially filed a conflict-of-interest statement affirming only that his research group had taken money from “various governments, scientific institutions and corporations.” But after Kuster co-authored a summary of the WHO’s findings in The Lancet Oncology, the medical journal issued a correction expanding on Kuster’s conflict-of-interest statement, noting payments from the Mobile Manufacturers Forum, Motorola, Ericsson, Nokia, Samsung, Sony, GSMA, and Deutsche Telekom. Nevertheless, Kuster participated in the entire 10 days of deliberations.39
“So what can you do? Straighten up, first of all, says Kenneth Hansraj, M.D., an orthopedic surgeon in Poughkeepsie, New York. And carry device at chest height with head up, chest open and shoulder blades back. Move just your eyes downward. And then, take a break. Your neck is not supposed to stay stuck in one position for a long period. If you’re reading on a tablet or phone, stop every so often to swivel and tilt your head — up and down, then side to side.” – 3 Dumb Things We Do with Smartphones, Good Housekeeping; Twitter: @goodhousemag
