How Your Cell Phone Can Make Mold More Toxic

Toxin Education
Written By Ivy Ham

Most of us know mold thrives in damp, poorly ventilated spaces. But what if another hidden factor in our modern homes is making it worse? Growing evidence suggests that electromagnetic fields (EMFs), which is basically just radiation that is put out from many electronics nowadays such as Wi-Fi routers, cell phones, and other devices, may actually increase mold growth and toxicity.

Fungi and Electromagnetic Fields

One of the first clinicians to raise awareness of this connection was Dr. Dietrich Klinghardt, MD, PhD. In a simple but mind-blowing experiment, he put identical mold cultures in two conditions: one shielded from EMFs, and one exposed to normal background radiation from Wi-Fi and nearby devices. The result was that the unshielded mold grew more aggressively and produced more spores, while the shielded culture showed far less activity. His conclusion: EMFs may act as a stimulant, pushing mold to become more biologically active.

Those of us that know about study design may question the replicability of this small-scale experiment, but we can actually see this happen in the real world as well. Fungi appear uniquely sensitive to radiation, even outside the lab. In fact, after the Chernobyl nuclear disaster, researchers exploring the damaged reactor were surprised to find black, melanin-rich fungi growing and thriving in one of the most radioactive environments on Earth. Later studies showed these fungi could actually use radiation as an energy source, similar to how plants use sunlight for photosynthesis.

Together, these findings suggest that fungi can detect and respond to electromagnetic and radioactive fields in their environment. While Chernobyl represents an extreme example of ionizing radiation and Klinghardt’s experiment focused on common wireless EMFs, both point to the same property: fungi don’t just passively grow, they adapt to and can even harness energy from invisible forces around them like EMF radiation.

EMFs and Fungal Behavior Studies

Electromagnetic fields are invisible waves from both natural and man-made sources. Non-ionizing EMFs (like Wi-Fi, Bluetooth, and cell phones) don’t break chemical bonds, but studies show they can still influence living cells. Studies are beginning to show that fungi and mold species seem especially sensitive.

  • A lab study on Aspergillus oryzae found that just 10 minutes of RF-EMF exposure triggered the fungus to secrete more proteins and enzymes, alongside a spike in calcium signaling, which is the same pathways molds use to release toxins.

  • Other research on entomopathogenic fungi showed changes in colony growth and spore production depending on frequency, with some molds thriving more at 900 MHz exposure.

  • Even common airborne fungi like Cladosporium have shown altered growth and pigmentation when exposed to electromagnetic wavelengths.

While not all studies measure mycotoxin output directly, the evidence suggests that EMFs can act as a stressor, pushing molds to become more active, grow more rapidly and become potentially more toxic.

Why This Matters

Indoor mold is already a major health concern, linked to allergies, respiratory issues, and immune disruption. If EMFs amplify toxin release, our increasingly wireless homes may be making existing mold problems harder on the body. Some researchers and clinicians, like Dr. Dietrich Klinghardt, have warned that EMFs could “wake up” dormant mold, pushing it to release more aggressive toxins.

If you know me in real life, you know that Rob and I run another small business that sells refurbished networking equipment, which requires testing hundreds of wireless routers and modems every day. This whole concept has me concerned because I believe our current rental home has several visible mold sources, some of which have been growing rapidly despite our best efforts.


Practical Takeaway

We can’t eliminate EMFs entirely, but being mindful of our exposure and our body’s terrain can definitely help — especially if you’re dealing with water damage or a known mold problem in your home. Try reducing your EMF load at night so your body (and your home environment) can rest, and then obviously you’ll need to address the mold situation by either removing yourself from the mold or by removing the mold from your home.

For my family, we are in a rental right now, and so we are limited with what we are aloud to do. We currently have several HEPA filters throughout the house to help reduce the amount of mold particles in the air, and we do our best to reduce EMF exposure by turning off most devices at night. I’m looking into grounding mats, grounding sheets and other ways to reduce our exposure, however we are also in the process of moving over the next few months, so it’s also a balance of what makes the most sense for our efforts.

Common household EMF sources to consider turning off at night:

  • Wi-Fi routers and mesh systems

    • Newer devices may have settings in their WiFi-management app that allows you to turn off WiFi on a schedule.

    • Older devices you can buy an outlet timer, and set it to turn off whatever is plugged into it during certain hours. They’re usually really cheap and easy to use.

  • Cell phones (especially charging on the nightstand)

    • Charge and store these at night in a different room from where you sleep. Blue light is bad for your circadian rhythm anyway, and this will help keep you from doom-scrolling into the night as well.

  • Bluetooth devices like earbuds, speakers, or fitness trackers

    • Many of these devices use Bluetooth, which produces a lot of EMFs.

  • Smart TVs, game consoles, and streaming boxes

    • Again, blue light is bad for your sleep rhythm since it mimics the sun and activates your brain into a more wakeful mode, messing with your sleep.

  • Cordless phones and baby monitors

    • These devices put off EMFs, and should not be near you while you’re sleeping.

The bottom line: Mold needs moisture to grow, but EMFs may be making it more aggressive. By controlling both humidity and unnecessary EMF exposure, you create a healthier environment for yourself and your family.
