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.
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:
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.
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:
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.
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.

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