Low EMF sauna facts

Most infrared sauna users are looking to improve health – making safety an important consideration when deciding what sauna to buy.

One thing to look out for when purchasing an infrared sauna are the Electromagnetic Fields (EMF) and Electric Fields (ELF).

The best infrared saunas have low EMF and ELF levels. Why is this important? Keep reading to find out.

What are EMFs or Electromagnetic Fields?

EMFs are energy waves with frequencies below 300 hertz or cycles per second. Magnetic fields are present whenever an appliance is using an electrical current.

The US Environmental Protection Authority has put a 3mG (milligauss) safety limit in place for EMF levels for human exposure.

Although the current scientific evidence provides no definitive answers regarding EMF, there is enough uncertainty that some people want to reduce their exposure to EMF.

What are ELFs or Extremely Low Frequencies?

ELF is the electric field with frequencies from 3 to 30 hertz. The most common ELF field is radiated by utility power lines.

You’re exposed to these fields whenever you’re near electrical appliances of any kind. The Threshold of Concern level for ELF is 1,000 mV.

Where do EMFs and ELFs come from?

EMFs and ELFs are all around us.

The EMFs and ELFs we encounter in our daily lives come from everyday things such as:

  • Power lines
  • Radar and microwave towers
  • Television and computer screens
  • Fluorescent lights
  • Microwave ovens
  • Cell phones
  • Electric blankets
  • House wiring

Plus hundreds of other common electrical devices – including infrared sauna heaters.

What are the risks of EMF emissions?

As mentioned above, EMFs are all around us. Hundreds of common electrical devices emit EMFs including televisions, computer screens, microwave ovens, cell phones and infrared sauna heaters.

The World Health Organisation states that: “While these devices have made our life richer, safer and easier, they have been accompanied by concerns about possible health risks due to their EMF emissions.”

This reputed sensitivity to EMF has been termed “electromagnetic hypersensitivity” or EHS.

The EHS symptoms most commonly experienced include:

  • dermatological symptoms (redness, tingling, and burning sensations) as well
  • neurasthenic and vegetative symptoms (fatigue, tiredness, concentration difficulties, dizziness, nausea, heart palpitation, and digestive disturbances).

What are safe levels of EMF and ELF in an infrared sauna?

Although the current scientific evidence provides no definitive answers regarding EMF, there is enough uncertainty that some people want to reduce their exposure to EMF.

For peace of mind, you’ll want to consider the Electromagnetic Fields (EMF) and Electric Fields (ELF) when purchasing an infrared sauna. Be sure to ask the retailer if their saunas are both low EMF and low ELF.

The guidelines for safe levels of EMF and ELF in your sauna are:

  • EMF Guidelines. The US Environmental Protection Authority has put a 3mG (milligauss) safety limit in place for EMF levels for human exposure.
  • ELF Guidelines. The Threshold of Concern level for ELF is 1,000 mV. With both EMF and ELF look for the lowest possible levels - 0 to 3mG for EMF and 200 mV to 1000 mV for ELF is considered acceptable.

In summary, to reduce your exposure and minimise potential harm, choose a low EMF infrared sauna. Look for infrared saunas with undetectable or extremely low EMF and low ELF.

Check to make sure your sauna has third-party tested results on its EMF levels. Learn more about infrared sauna safety in this article.

Are infrared saunas safe?

If you’re looking at getting an infrared sauna and thinkign about safety, you may also be wondering about infrared heat and if it’s safe.

The short answer is, yes, infrared heat is completely safe. In fact, it is so safe, hospitals use similar heaters to warm newborn babies.

Infrared is a part of nature and essential for life. All objects give off and receive infrared heat. Learn more about infrared sauna safety in this detailed article.

In summary

We hope this article has answered your questions about EMF and ELF levels and why it’s important to choose a low EMF infrared sauna.
