Electronic devices we use every day, have not been around very long. For example, although the cell phone has grown over the past twenty years, it is only recently that they have become pervasive. Everyone now own one. As a result, it is only now that we are beginning to understand what the long-term health effects of low levels of Electromagnetic Radiation (EMF) emitted from these electronic devices.
The growing body of scientific research indicates that electronic emissions do have an effect on human biology. There are health risks linked to exposure, and we should expect more studies designed to improve our understanding.
The following is a list of health concerns linked to Electromagnetic Radiation exposure and synopsis of current research findings:
Studies by Health Concern
In a study, researchers found that babies born to women who were exposed to stronger EMFs during pregnancy had more than 3x the risk of developing asthma than babies born to mothers exposed to weaker EMFs. In Australia, the Institute of Health announced in 2007 that the 5 leading causes of non-fatal illness for the country were: diabetes, ischemic heart disease, dementia, asthma, anxiety and depression. All of these were linked to the sudden explosion of wireless technology ~15 years ago.
Autism Spectrum Conditions (ASCs) involve multi-level disturbances of underlying biology. They have been indicted as a result of biological effects of Radio Frequency (RF) EMF radiation exposure. It is hypothesized that the Electromagnetic Radiation exposure causes oxidative damage and cellular stress to proteins, which results in neurological harm. Electromagnetic Radiation is purported to set the biological balance out of tune and exacerbate symptoms of ACS for those who possess the disorder.
Non-ionizing radiation leads to heat generation. Thermal effects can lead to burns. Two patients suffered inadvertent injury to their oral mucosa, requiring medical treatment, after the ingestion of microwave-heated food. Thermal burns can also be caused by exposure to laptops or other electronic devices. Care must be taken to be cognizant of the heat generated by electronic devices.
Laptops, tablets and cell phones emit both Radio Frequency (RF) and Extremely Low Frequency (ELF) radiation, which can be absorbed the tissues closest to where the device is used. Some research has associated radiation exposure to multiple forms of cancer. More research is needed because how people are using their electronic devices vary along with their ages getting younger and younger. More evidence is needed, as skeptics challenge the conflicting reports.

Typically, brain cancer is a rare condition. Epidemiological studies indicate brain tumors account for 1.4% of all cancers and 2.4% of all cancer-related deaths. Nonetheless, statistical evidence has pointed to the increased incidence of rare forms of brain cancer and evidence has pointed to EMF exposure as one possible cause.

In 2013, an article was published which received a good deal of short-term media attention. Public awareness seems to have faded since then. The study showed the cause of 4 women under age 40 whom had developed breast cancer without previous family history or genetic disposition. These young women, ages 21 to 39, were found to have developed breast cancer in the shape of their cell phones in the region of the breast tissue, where they had kept their cell phones daily over the course of 10 hours a day for several years. In a more recent 2014 study, researchers found that Extremely Low Frequency (ELF) EMFs may be increase the risk of human breast cancer and that a woman’s exposure to ELF-EMFs may be the risk factor of breast cancer when they are non-menopausal.

Research has indicated that there may be a slight increased risk for leukemia in children caused by exposure to electromagnetic fields. Homes with high levels of Electromagnetic Radiation, due to the proximity of overhead power cables, had an increased incidence of children whom developed this disease. Because only a small number of children got this rare condition, researchers concluded that the results could be due to other factors or chance despite the results being repeatable. International teams of scientists have since tried to study the correlation. They have been unable to explain the mechanism that causes the disease. Some argue that Electromagnetic Radiation must not cause leukemia because if it did stronger evidence would have been found by now. However, this is a mistake. Scientists themselves say it takes many years to definitively prove any theory or, for that matter, many years for the cancers to emerge once exposed. Just because not enough evidence can be found today does not mean the evidence does not exist.
Some individuals report suffering from electromagnetic hypersensitivity due to non-ionizing radiation exposure. Typical symptoms associated with this disorder include: headache, fatigue, stress, sleep disturbances, skin symptoms, muscle ache or pain, and other health problems. Presently, there is a controversy as to whether or not individuals can be electromagnetic hypersensitive because some exposed individuals were not able to distinguish between placebo and actual Electromagnetic Radiation fields. However, this is not to say that all individuals cannot be electromagnetic hypersensitive.
Electromagnetic fields effects on humans and all animals is a concern. Published in 2014, cow enzymes were studied as a model for animal exposure. Exposure to non-ionizing radiation resulted in bovine enzyme changes. Some enzymes were disabled completely. Others exhibited unusual patterns. Yet, others did not react. Thus, these findings corroborate the theory that some individuals may be sensitive to radiation while others are not.
Rabbits’ eyes were exposed to radiation, similar to that emitted by common electronic devices. Forty rabbits were tested. The eyes were then stained and measured for corneal damage and epithelial cell loss. It was found that three types of millimeter-wave antennas can cause thermal injuries of varying type and levels. These waves can penetrate below the surface of the eye.
One study has found that different health symptoms, such as depression, memory status, insomnia, and hair loss, were significantly associated with exposure to EMR from mobile towers.
Another study summarizes the evidence stating that excessive exposure to magnetic fields from power lines and other sources of electric current increases the risk of development of some cancers and neurodegenerative diseases, and that excessive exposure to RF radiation increases risk of cancer, male infertility, and neurobehavioral abnormalities.
A third study tended to suggest a need for more cautious use of cell phones with children, because children are expected to experience a longer lifetime exposure to Radio Frequency (RF) radiation from cell phones.
Several studies done in rat models have shown that electronic devices like laptops and cell phones were able to negatively impact sperm quality. Sperm became defective with DNA damage and malformations, which decreased the sperm motility. In humans, similar results were found. Thus, there is caution from the medical community for men to avoid putting cell phones in their pant pockets.

Potential correlations have been found with cell phone use and negative impact on erectile dysfunction. Research in this area is new and trending. More data is expected to come out shortly.
One current study has found that prolonged computer and mobile phone use is associated with a 6-fold increase in the risk of miscarriage. In another study, researchers found exposure to 2450 MHz EMF, particularly in the prenatal period, resulted in postnatal growth restriction and delayed puberty in female Wistar rats. According other researchers, the fetus is most susceptible to radiation during organogenesis (2-7 weeks after conception) and in the early fetal period (8-15 weeks after conception).
Research also suggests that in-utero exposure to EMF can cause childhood obesity. Children who were exposed to high level of EMF while in the mother’s womb had ~70% risk of suffering from weight problems or obesity during childhood than children who had low in-utero exposure to magnetic fields.
At high levels of radiation exposure, the following can occur: spontaneous abortion, growth restriction, mental retardation, childhood obesity and cancer. Some articles argue that studies have not consistently found a link between non-ionizing radiation and disease. However, the fact that some links have been found is disconcerting. Caution is advised to pregnant women to avoid an unnecessary radiation exposure.

Studies have found that Extremely Low Frequency (ELF) and Radio Frequency (RF) Electromagnetic Radiation can cause impairment and mutations in DNA, which can lead to cancer. Other studies find that Electromagnetic Radiation may lead to changes in the physiological indices, genetics, and immune function of the operators.

In a Chinese study, published in May 2014, Electromagnetic Radiation induced by a 900 MHz cell phone was determined to affect the expression of the Nrf2 protein and induce abnormal morphology of liver cells, causing oxidative injury. The publication was looking for ways to reverse damage to the liver caused by cell phone radiation.
Studies have been published describing cognitive and physiological effects of extremely low frequency magnetic field exposure.
Radiation is energy. Too much of it can cause an adverse effect. According to the EPA, there are two types of health effects associated with exposure to radiation. The two categories are: those arising from stochastic or long-term, low-level chronic exposure and those arising from non-stochastic or high levels of radiation exposure. Generally, non-ionizing radiation effects are deemed to be stochastic in nature, as the radiation is considered lower energy and therefore may take time to show noticeable effect. A variety of ailments are associated with stochastic radiation exposure. Radiation has even been indicted as an environmental toxin, which synergizes with other pollutants to cause an exacerbated negative effect.
Laptops can reach temperatures upwards of 110-115 ºF. Toasted skin syndrome is a condition in which reddish-brown hyperpigmentation is seen on the surface of the skin, caused by heat and radiation exposure from laptops.The pigmentation change was, thus far, irreversible.
