When you’re thinking about buying an infrared sauna, EMF (Electromagnetic Fields) and ELF (Extremely Low Frequency) might not be the first things on your mind, but they’re worth considering. These are energy fields that surround electronic devices—including saunas—and some people worry about the potential health effects of long-term exposure.

In this article, we’ll break down what EMF and ELF really are, how they relate to infrared saunas, and whether or not you should be concerned.

More importantly, we’ll look at how you can minimize your exposure while still enjoying the benefits of a sauna.

What Are EMF and ELF?

EMF, or electromagnetic fields, are areas of energy that form around any device that uses electricity. This includes everything from your phone and computer to household appliances like microwaves.

In infrared saunas, the EMF comes from the electrical components used to generate heat. ELF, or extremely low frequency, is a specific type of EMF that has very low energy but can still be found in things like power lines and electrical wiring.

The difference between EMF and ELF lies in their frequency. EMF can cover a wide range of frequencies, from low to high, while ELF only refers to the lower end of the spectrum. Both EMF and ELF are measured in specific units—milligauss for ELF and volts per meter for EMF.

You’re likely exposed to EMF and ELF every day, even without stepping into a sauna. From your morning cup of coffee heated in the microwave to charging your smartphone, these fields are always around.

However, many people are becoming more aware of their potential effects on health, especially when they’re emitted by devices like saunas that are used regularly and for longer periods.

How EML and ELF Works in Infrared Saunas

There are three types of infrared light used in saunas—near, mid, and far infrared. Each type reaches different depths in your skin, with far infrared being the most commonly used in saunas. The downside? The electrical components used to produce this heat also generate EMF and ELF.

While the focus is on the heat and health benefits, the EMF and ELF levels these saunas emit can sometimes be overlooked. Knowing how infrared saunas work can help you understand why these fields are present and whether they’re something to be concerned about.

Most users prioritize the relaxing heat and sweat-inducing effects of the sauna, but it’s good to also be aware of what’s happening behind the scenes.

Typical EMF and ELF Levels in Infrared Saunas

Infrared saunas do emit EMF and ELF, but how much varies depending on the brand and model. Most saunas on the market aim to keep these levels as low as possible, but they can still range between 1 and 10 milligauss for ELF and 0.5 to 20 volts per meter for EMF. To put this into perspective, household appliances like vacuum cleaners can emit far higher levels of EMF, often reaching up to 100 volts per meter when in use.

When comparing saunas, you’ll notice that some advertise as "low-EMF" or "low-ELF." These labels indicate that the sauna has been specifically designed to minimize exposure. Many brands have made reducing EMF and ELF a key feature of their products, often including certifications or test results to back up their claims.

Global safety limits set by organizations like the World Health Organization (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) provide guidelines for exposure. These limits suggest that anything under 2000 milligauss for ELF and 100 volts per meter for EMF is considered safe for the general public. Most infrared saunas stay well below these limits, but it’s always worth checking the specifications if this is a concern for you.

Understanding the typical levels found in saunas can help you make a more informed choice. While many users don’t notice any immediate effects from EMF and ELF exposure, it’s always good to know what’s happening behind the relaxing heat.

Potential Health Risks of EMF and ELF Exposure 

One of the main concerns with EMF and ELF exposure is the potential long-term health effects. While research is still ongoing, some studies suggest that high levels of EMF exposure could be linked to various health issues.

However, it’s important to keep in mind that most of these studies focus on environments with much higher EMF levels than what’s found in infrared saunas.

• Headaches: Some studies suggest a potential link between high EMF exposure and frequent headaches.
• Sleep disturbances: Exposure to higher levels of EMF may interfere with sleep patterns.
• Other serious conditions: Long-term exposure to high EMF levels has been studied for potential links to conditions such as cancer, although the evidence is not conclusive.

ELF exposure has also been researched, particularly for its effects on the nervous system and cells. However, the levels emitted by most household appliances and infrared saunas are generally considered too low to cause significant harm.

Both the World Health Organization (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) agree that the EMF and ELF levels found in everyday electronics, including saunas, fall within safe exposure limits.

That said, some people do report experiencing symptoms after using devices that emit EMF or ELF. These symptoms include:

• Headaches
• Dizziness
• Fatigue

However, these reports are often anecdotal and not necessarily tied directly to sauna use. For most people, the health benefits of using an infrared sauna—such as improved circulation, relaxation, and detoxification—far outweigh the potential risks of EMF and ELF exposure.

How Infrared Saunas Minimize EMF and ELF Exposure

Manufacturers of infrared saunas are well aware of the concerns around EMF and ELF exposure, and many have taken steps to minimize these fields in their products.

One way infrared saunas reduce EMF and ELF is through the use of carbon-based heating panels, which tend to produce less electromagnetic radiation compared to older ceramic heaters. Another technique is shielding the electrical components to prevent unnecessary EMF emissions. These methods, combined with strategic placement of heating elements, help ensure that the areas where you sit or lie down in the sauna are exposed to minimal EMF and ELF.

If minimizing exposure is important to you, it’s a good idea to look for infrared saunas that advertise low-EMF and low-ELF designs. Brands that go the extra mile often provide certifications or test results to prove their claims. This way, you can verify that the sauna you’re buying has been designed with your safety in mind.

While no sauna can be entirely free of EMF and ELF, choosing one with these reduction technologies will help you enjoy the benefits of infrared therapy with peace of mind.

How to Test and Measure EMF and ELF in Your Sauna

If you want to be absolutely sure of the EMF and ELF levels in your sauna, you can test them yourself with a handheld EMF meter. These devices are affordable and easy to use.

They measure both EMF and ELF levels in your environment and give you a clear picture of how much exposure you’re dealing with.

Here’s how to test your sauna:

• Turn on the sauna: Let it heat up for about 10-15 minutes, as this is when the electrical components are most active.
• Use the EMF meter: Take readings around the interior of the sauna, focusing on areas where you’ll be sitting or lying down.
• Compare the readings: Check the readings against the safety limits: under 2000 milligauss for ELF and under 100 volts per meter for EMF.
• Adjust your position if needed: If the levels are higher than expected, try adjusting where you sit to reduce your exposure.

If you find that your sauna’s EMF or ELF levels are higher than advertised, it’s worth reaching out to the manufacturer to discuss your concerns. Some saunas may require slight adjustments to reduce these levels, or the manufacturer may offer advice on how to minimize exposure further.

Testing your sauna gives you control and ensures you know exactly what kind of environment you’re exposing yourself to. It’s a simple step that can provide extra reassurance.

Should You Be Concerned About EMF and ELF in Infrared Saunas?

The short answer is: probably not.

Most infrared saunas on the market today are designed with EMF and ELF safety in mind. Even if you’re exposed to these fields, the levels are typically well below the safety limits set by health organizations.

For the average user, EMF and ELF exposure in saunas is unlikely to pose any serious health risks. The technology has advanced to the point where manufacturers are actively reducing these fields to keep customers safe. Plus, the health benefits of using an infrared sauna—improved relaxation, detoxification, and circulation—are well-documented and can contribute to overall wellness.

That said, if you’re someone who is particularly sensitive to EMF or simply prefers to limit exposure, there are plenty of low-EMF sauna options available. And, as mentioned earlier, you can always test the levels yourself to make sure they fall within the safe range.

Ultimately, EMF and ELF shouldn’t be a major concern when using an infrared sauna. As long as you’re using a reputable brand and following safety guidelines, you can enjoy the benefits of infrared therapy without worrying too much about these fields.
