The Thyroid, Adrenal, and EMF Connection

I’ve worked with thousands of people with Hashimoto’s, as well as many individuals navigating chronic infections like Lyme disease and mold exposure (both of which can be triggers for Hashimoto’s). One pattern I’ve noticed time and again is that some of the people who are most affected by these conditions also report being especially sensitive to electromagnetic fields, or EMFs.

For some, this sensitivity shows up as headaches, fatigue, brain fog, difficulty sleeping, or a feeling of being “wired but tired” after spending time around Wi-Fi routers, cell phones, or other electronic devices. While these experiences are very real for many people, the role of EMFs in human health remains a topic of ongoing research and debate.

For someone whose body is already under significant stress from autoimmunity, chronic infections, environmental toxins, nutrient deficiencies, or ongoing inflammation, EMFs may be one more burden on an already overwhelmed system.

EMFs can be a controversial topic. The science is still evolving, and we don’t yet have all the answers. I’ve learned throughout my career that many health concerns once considered unconventional eventually gain broader acceptance as more research emerges. Rather than dismissing a potential contributor simply because it isn’t fully understood, I believe it’s worth exploring with an open mind, so let’s look a little deeper at EMFs.

What Are EMFs?

Electromagnetic fields (EMFs) are invisible areas of energy generated by both natural sources, like the Earth’s magnetic field, and human-made sources, including cell phones, Wi-Fi routers, power lines, Bluetooth devices, laptops, smart meters, and power lines. As our use of wireless technology has grown, so has our daily exposure to EMFs.

While modern technology has brought countless benefits, it has also introduced levels of EMF exposure that are far greater than those experienced by previous generations. Researchers are continuing to investigate how chronic, long-term exposure may influence biological systems and whether certain individuals may be more susceptible to its effects than others.

A growing body of research suggests that EMFs deserve continued attention, particularly when it comes to understanding their potential impact on thyroid and adrenal health.

The Thyroid and EMF Connection

Because the thyroid gland is located in the neck (close to where many people hold their cell phones), it has become an area of interest for researchers studying the health effects of EMFs. While the research is still evolving, several studies suggest that chronic exposure to certain types of non-ionizing electromagnetic radiation may influence thyroid function, particularly through increased oxidative stress. (1,2)

Unlike ionizing radiation (such as X-rays), the radiofrequency (RF) waves emitted by cell phones and other wireless devices do not have enough energy to damage DNA directly. However, researchers have proposed that RF radiation may produce both thermal effects (slight tissue heating) and non-thermal effects, including changes in cellular metabolism and increased production of reactive oxygen species, which can contribute to oxidative stress.

Oxidative stress is especially relevant for people with Hashimoto’s, as it has been shown to play a role in autoimmune thyroid damage. Some studies have found that prolonged EMF exposure may alter thyroid hormone levels, including free T4, TSH, and, in some cases, T3. (3) Research involving people with occupational exposure to extremely low-frequency (ELF) electromagnetic fields, such as workers near high-voltage power lines, has also suggested that long-term exposure may impair the conversion of T4 into the active thyroid hormone T3 while increasing markers of oxidative stress. (4,5)

Other studies have explored whether frequent cell phone usage is associated with thyroid conditions and issues such as hypothyroidism, goiter, thyroid nodules, and even thyroid cancer. (6-8) While some findings have suggested possible associations, the evidence remains mixed, and researchers have not established a clear cause-and-effect relationship. More high-quality studies are needed to determine whether EMFs directly contribute to thyroid disease or whether other factors may be involved.

This research raises important questions about whether reducing unnecessary, long-term EMF exposure may be an important way to support thyroid health.

The Adrenal and EMF Connection

If you’ve been following my work for a while, you know I often talk about the relationship between the thyroid and the adrenal glands. Many people in my community report a period of significant stress before the onset of their Hashimoto’s, which is why supporting adrenal health is an important part of my root-cause approach.

Stress can go beyond psychological and emotional stress. It also includes things like blood sugar imbalances, chronic infections, mold exposure, nutrient deficiencies, emotional stress, or environmental toxins. To the body, EMFs can be interpreted as an additional stressor.

Some studies suggest that EMFs may influence the body’s stress response by increasing oxidative stress and affecting the nervous system. (9,10) In one 2018 study, rats exposed to cell phone EMFs for six hours per day, over four to eight weeks, had significantly higher levels of ACTH (the hormone that signals the adrenal glands to produce cortisol) and cortisol compared to rats that were not exposed. (11) The effects were even more pronounced after eight weeks of exposure. Researchers also observed structural changes in the adrenal glands, including an enlargement of the zona fasciculata (the region responsible for producing cortisol).

On their own, these effects may be relatively small, but when they’re layered on top of other ongoing stressors, they contribute to the body’s total stress load.

Minimizing additional stressors where you can may help create an environment that’s more supportive of healing. This doesn’t mean you need to eliminate technology from your life (and that would probably prove to be pretty challenging!), but it would be helpful to reduce your overall stress burden whenever possible.

Reducing EMF Exposure

While we can’t eliminate EMFs entirely, there are simple steps we can take to reduce unnecessary exposure. Here are a few strategies I recommend:

• Avoid carrying your phone directly against your body whenever possible. Instead, keep it in a purse, backpack, or bag.
• Use speakerphone or wired headphones for longer phone calls to increase the distance between your phone and your head.
• Keep phones, tablets, and other electronic devices away from your bed while you sleep.
• Turn off your Wi-Fi router at night (if it’s practical for your household).
• Create lower-EMF spaces in your home by limiting unnecessary wireless devices in areas where you spend the most time resting or relaxing.

As with many aspects of health, I like to start with the simplest interventions first. Reducing exposure where it’s practical is often my first recommendation because it’s inexpensive and easy to implement. For some people, particularly those who feel they are especially sensitive to EMFs, additional tools like Harmoni’s EMF-protection products may be helpful.

Harmoni creates products that help protect you and your family from everyday EMF exposure. Check out some of their most popular products:
