Is EMF Really That Harmful? Answers from the Latest Research

Technology has permeated into every area of our lives. Between smartphones, Wi-Fi routers, laptops, gaming systems, and wireless accessories, we're constantly "plugged in." With our increasing reliance on technology, people have started to ask questions about our exposure to electromagnetic fields (EMFs). The biggest question on everyone’s mind is: Are EMFs harmful to our health?

Global health organizations have acknowledged the potential risks of EMF exposure, but positions vary. The World Health Organization (WHO) established the International EMF Project to assess health and environmental impacts of EMF in 1996 to encourage “focused research to fill in gaps in knowledge and to facilitate the development of internationally acceptable standards limiting EMF exposure.”

The research is out there, but it’s not often talked about. You’ll find a lot of conflicting information from a wide range of sources, so it’s important to do your own research. Let’s take a look at the most up-to-date science and see what these recent studies have concluded about the risks of EMF exposure. 

Before diving in, it’s important to understand what exactly EMFs are. There are two types of electromagnetic fields:

• Ionizing radiation: This is the high-frequency radiation from X-rays and other sources that have been proven harmful in large amounts.

• Non-ionizing radiation: This is the low-frequency radiation emitted by our everyday electronic devices such as cell phones, laptops, and microwaves.

The non-ionizing EMFs are the cause for concern right now because we are exposed to this radiation nearly all day, every day. For years, we have been told the radiation from our phones and wireless devices is perfectly “safe.” But between outdated regulations and the lack of long-term data to back this claim, many people are starting to wonder if EMF could be causing more harm than we realize. And as our reliance on technology grows, our cumulative exposure is becoming significant. But is it really a threat?

In 2011, the World Health Organization released a statement classifying electromagnetic fields (EMFs) as “possibly carcinogenic” to humans. According to the Chairman of this study, Dr. Jonathan Samet, “The evidence, while still accumulating, is strong enough to support a conclusion and the 2B classification. The conclusion means that there could be some risk, and therefore we need to keep a close watch for a link between cell phones and cancer risk.”

Fast forward a couple of years to 2018, when the National Toxicology Program concluded that there was “clear evidence that male rats exposed to high levels of RF-EMF like that used in 2G and 3G cell phones developed cancerous heart tumors.”

The question whether or not EMF causes cancer is not something that can be easily answered with a definitive “Yes” or “No.” It’s difficult to pinpoint exactly what causes cancer, so we rely on epidemiological studies which investigate patterns and causes of health issues in a population. In EMF research, they help scientists understand potential links between EMF exposure and health effects like cancer, by studying large groups of people over time. Based on one of the most recent epidemiological studies conducted in 2022 by the International Journal of Molecular Sciences , “There is a consensus on the positive relationship between residential/domestic exposure to EMF and the occurrence of brain cancer.”

Another area of concern is how EMF could be affecting the brain - specifically memory, attention, and overall cognitive function. Especially in children, whose brains are still developing, there has been compelling evidence that EMF exposure is potentially harmful to brain function

• A  2017 study conducted by the Journal of Microscopy & Ultrastructure  determined that the use of mobile phones for more than 90 minutes per day was linked to increased concentration and attention problems. 

• A 2015 study published by Environment International investigated how RF-EMF from wireless device usage affected memory performance. Researchers concluded a decline in memory performance after one year associated with longer durations of cell phone use and more strong RF-EMF doses.

• Another study conducted by researchers at Monash University in Australia studied cognitive function among secondary students based on their cell phone usage. Over the course of their study, they recorded poorer working memory, reaction time, learning response time, and accuracy among children who reported a higher number of mobile phone calls.

• A 2013 study by the Indian Journal of Biochemistry and Biophysics showed significant impairment in cognitive function and an increase in oxidative stress, a condition in which the body does not have enough antioxidants to fight the amount of free radicals.

The blood-brain barrier is the brain’s defense against harmful substances. It regulates the movement of substances between the blood and the brain, and it protects the central nervous system. Research has shown that EMFs increase the permeability of the blood-brain barrier, making it easier for toxins to get through and reach the brain.

Research is ongoing, but these findings suggest that heavy and prolonged exposure to EMFs could impact brain health, especially in younger individuals.

So many factors can impact fertility, and researchers have been looking into environmental toxins, including EMF, as possible contributing factors to infertility. With our heavy tech use in modern society, studies are looking into whether long-term exposure to EMFs - specifically from phones and laptops in close proximity to reproductive organs - could be impacting fertility. 

There have been a number of studies recently published that report male reproductive organs are susceptible to EMFs. This isn’t something that can be tested on humans directly, so scientists are relying on other mammal studies to determine whether or not this radiation is harmful to the testes. 

• This  2018 study  concluded that 2.45 GHz radiation exposure caused oxidative stress in testes and could be leading to negative effects on fertility potential of the rodents tested. For comparison, our cell phones emit between 600 MHz and 39 GHz.

• Another recent study, also conducted on rodents, found that 5 weeks of RF-EMF exposure of less than 1 GHz adversely impacted the vitality and motility of sperm.

• A study conducted by Frontiers in Public Health exposed the test subjects to 1.8 GHz of radiofrequency EMF and determined that this exposure is capable of generating  reactive oxygen species (ROS). This is a type of unstable molecule that reacts with other molecules in a cell, and build-up of ROS in cells can lead to DNA and RNA damage.

For females, there are two major areas of concern when looking at EMFs and reproductive health: fertility and pregnancy. Animal studies conducted within the past decade suggest that EMF exposure during pregnancy could impact fetal development. Human studies are limited, but observational data indicates a potential risk as well.

• A study from the Clinical and Experimental Reproductive Medicine journal found that EMF exposure altered the reproductive endocrine hormones, embryonic development, and fetal development in rodents.

• A 2017 study  found that mobile phone radiation induces oxidative stress, which affects the reproductive performance of the test subjects.

• A study published by the Malaysian Journal of Medical Sciences in 2023 found EMF exposure could increase miscarriage risk during pregnancy. The study explored several theories for this connection, such as the possibility that EMF may alter chemical interactions in cell membranes, they may increase free radicals in the body, they could damage cell proteins, and they may decrease permeability of cell membranes which leads to decreased cell connections. 

Experts recommend anyone who is pregnant or trying to conceive reduce their overall EMF exposure to mitigate the potential risk. Remember - proximity increases exposure, so limit direct body contact with phones and tablets, and think about investing in some EMF protection devices. 

Sleep problems are one of the most common complaints associated with EMF exposure. Our bodies’ circadian rhythms are finely tuned to natural electromagnetic signals, so it’s no wonder that artificial EMFs from the devices we’re handling all day could be disrupting these rhythms.

• EMF exposure affects the pineal gland, which results in suppressed melatonin production. Not only does melatonin regulate our sleep cycles, but it also has anticarcinogenic and free radical scavenging properties. With that in mind, reducing melatonin impacts sleep and overall health.

• Another recent study identified that the pineal gland is likely to sense EMFs as light, therefore it may reduce the melatonin production.

Experts recommend reducing EMF exposure through lifestyle changes and utilizing EMF protection devices, such as the Lifetune devices from Aires Tech, to mitigate potential risks from EMFs.

Today’s children were born into an EMF-saturated world. Their exposure to Wi-Fi and cell phone signals began on day one, so their cumulative exposure to EMFs is much higher than the average adult. At the same time, their developing brains and bodies are also more vulnerable to EMF radiation.

• A 2020 study published by Clinical and Experimental Pediatrics identified that while the skull thickness of an adult is approximately 2mm, the skull thickness of a 5-year-old child is only about 0.5mm. Therefore, radiation penetration is greater in children.

• Safety guidelines for cell phone compliance are tested through SAM (Standard Anthropometric Mannequin), which is a fluid-filled model that would be the same size as a six foot, two inches, 220lb male. This measures how much tissue is heated to determine the SAR (Specific Absorption Rate) of a cell phone. These safety guidelines do not take children into account.

• Other studies have found that RF-EMF can pose a risk for demyelination , or the breaking down of myelin - a fatty substance that insulates neurons. Children, whose myelin is still not fully developed in certain areas of the brain, have a higher risk of myelin degeneration.

Mitigating risk from EMFs by reducing exposure and using EMF protection is especially important in homes with children, whose developing bodies and brains are the most vulnerable to the effects of EMF.
