What EMF Exposure Does to Humans—and Why Lower Is Better in Saunas

If you're considering an infrared sauna, you've probably come across the term EMF. Short for electromagnetic fields, EMFs are emitted by most electric devices—including sauna heaters. But how do EMFs affect your body, and does it really matter how much you're exposed to during a sauna session?

In this article, we break down what EMF exposure does to the human body and why choosing a low-EMF infrared sauna is one of the most important decisions you can make for your health and wellness.

What Are EMFs?

Electromagnetic fields (EMFs) are invisible areas of energy, often referred to as radiation, associated with the use of electrical power and various forms of natural and man-made lighting. There are two main types:

Low-frequency EMFs: From household appliances, wiring, Wi-Fi routers, and electric sauna panels
High-frequency EMFs: From cell phones, microwave ovens, and X-rays

While low-frequency EMFs are generally considered less hazardous than ionizing radiation, there is growing concern about the potential long-term health effects of daily exposure—especially in enclosed environments like saunas.

How EMF Affects the Human Body

Some studies suggest that prolonged exposure to elevated EMF levels may contribute to a range of biological effects. Though research is ongoing, reported risks include:

Sleep disruption and melatonin suppression
Cellular stress and oxidative damage
Hormonal imbalance (affecting thyroid and adrenal glands)
Electromagnetic hypersensitivity (EHS) symptoms such as headaches, fatigue, and brain fog
Potential links to cancer and fertility issues (as noted by the WHO and IARC)

While EMF exposure from a single device is typically minimal, the cumulative effects from multiple sources—especially in a confined space like a sauna—are a concern for many health-conscious users.

Why EMF Levels Matter in Infrared Saunas

Infrared saunas use heating panels powered by electricity, and those panels can generate varying amounts of EMF depending on their design and shielding. During a session, your body is sitting inches from these active sources for 20–40 minutes at a time.

The lower the EMF levels, the safer and more relaxing your sauna session will be.

Premium brands like Finnmark Designs, Dynamic, Golden Designs, and Maxxus offer low-EMF, ultra-low EMF, or Near Zero EMF saunas, lab-tested to be < 2.0 mG at body contact range
Cheaper models may advertise "low EMF" but lack third-party verification
Red light panels and hybrid saunas should also be evaluated for EMF output

Recommended EMF Thresholds for Sauna Safety

EMF (Electromagnetic Field) levels are measured 6-8 inches from the heating panels. All our saunas are safe and well below harmful levels:

Low (6-10 mG): Most affordable option, typical for infrared saunas, and perfectly safe for everyday use.
Ultra Low (Under 3 mG): Lower exposure for added peace of mind, still budget-friendly.
Near Zero (Under 2 mG): Lowest possible EMF for those most sensitive or concerned about exposure, with premium features.

Choose 'Low' for the best value, or 'Near Zero' if minimizing EMF is your top priority.

These levels are typically measured at the point of contact where your back, legs, or arms would touch the sauna panel or bench during a session.

How to Reduce EMF Exposure in Your Sauna

Buy a sauna from a trusted brand that lists third-party EMF test results
Use shielded wiring if you're building a DIY sauna
Keep electronic devices (phones, tablets) out of the sauna during sessions
Opt for ceramic or carbon panels that are certified low-EMF

Final Thoughts: Your Health, Your Environment

Infrared saunas can offer amazing benefits—from detoxification and pain relief to mood and immune support. But if you’re using a unit that exposes your body to high levels of EMFs, you may be adding an invisible stressor that cancels out the wellness gains.

That’s why we always recommend choosing a low-EMF, ultra-low, or Near Zero EMF infrared sauna—especially if you plan to use it frequently or have any sensitivity to EMFs.
