Due to its numerous health benefits, far infrared or FIR saunas continue to rise in popularity. They have been known to help people lose weight, reduce stress, ease chronic pain, and help the body detox. However, not all FIR saunas are created equal when comparing the level of exposure to EMF or electromagnetic fields. For this reason, it’s important to have an understanding of EMF and ELF when purchasing a sauna.


Most people who buy saunas use them multiple times a week for up to 30-40 minutes per session. Repeated exposure to a high level of EMF could be harmful to their health. Not all sauna models conduct the same frequency levels, and the good news is there are low EMF saunas available.

The solution is to ensure the far infrared sauna you are buying or using does not expose you to a high-EMF environment. With updated technology and modernized design, FIR saunas with low EMF and ELF are an option. Understanding how a FIR sauna works and the associated safety information is important to know before purchasing a sauna for your home or business.

What Is EMF?

Radiation is the invisible energy produced by electricity. Also referred to as electric and magnetic fields, these areas move a current through a wire and are all around us. The EMF fields are measured in milligauss (mG) and the ELF fields are measured in volts per meter. People who are highly sensitive to EMF can reduce exposure by eliminating or reducing the use of electrical devices in the home. Electromagnetic fields (EMF) are energy waves with frequency levels below 300 hertz or cycles per second.

There are two types of EMFs: higher-frequency and low- to mid-frequency. Someone exposed to a higher-frequency EMF, is subject to possible DNA or cell damage. While the research does not show low-frequency levels to be as harmful as higher frequencies, some people are very sensitive to the low-frequency.

What Is ELF?

Extremely low frequency (ELF) are electric fields with frequencies from 3 to 30 hertz. It is a non-ionizing radiation and sits on the low end of the electromagnetic spectrum.

Although most devices sit on this low frequency field, flat screens that use cathode ray tubes may expose people to a higher level of ELF radiation, but the amount still falls well below the government threshold. People can reduce their exposure to ELFs by turning off electrical devices not in use and immediately repair any faulty wiring which may generate higher ELF levels.

Health Concerns Linked to EMF

Different studies show varying results that increased exposure to high levels of EMF can lead to health problems including cancer, birth defects, and Lou Gehrig’s disease. EMF levels at increased rates have also been linked to symptoms such as headaches, fatigue, dizziness, and skin rashes.


Most of what we are exposed to in our typical environments are at such low EMF levels, we are not at risk. However, with the increase of technology and electrical devices we occupy ourselves with on a daily basis, any chance we have to reduce our exposure is best for our health.

Choose a Low EMF Sauna

To receive maximum benefit from your infrared sauna you will want to use your sauna 3-5 times per week.  The more you use your infrared sauna, the more important it is to choose a low EMF and low ELF infrared sauna.


Far infrared saunas have a number of health benefits to offer every user. With infrared heating, the air temperature stays low. It is less about heating the air in the sauna itself and more about heating the human body and raising your core body temperature.

With the understanding of EMF, the general recommended use for a FIR sauna is 20-40 minutes a day, 3 to 5 times a week. Also, because the heat of the sauna helps a body sweat out toxins, it’s best to rinse off afterwards so the toxins are not reabsorbed into the skin.

In order to take advantage and not negate any of the therapeutic and wellness benefits a FIR sauna provides, it’s best to choose a low EMF infrared sauna option to limit exposure to harmful rays.


Now that you’ve decided to enhance your overall health and wellness with an infrared sauna, how do you decide which one to purchase? Although the sauna selection process may seem overwhelming, it doesn’t have to be. Here are 10 helpful tips to ensure you make a sound investment when selecting an infrared sauna.

1: Decide on DIY or Kit

You can choose to build your own custom sauna or you can select from a variety of sauna kits that come with everything you need and install in about an hour.

Ask yourself: ‘How handy am I?’ If your idea of being handy is changing the occasional lightbulb, set your sights on an easy-to-assemble package ready to be put together this weekend. Now, if you’re the jack-of-all-trades, get-it-done-myself type, prove your worth and DIY it from the ground up!

2: Select the Appropriate Sauna Size

Will it just be you or will others be enjoying the sauna as well? Some infrared saunas only accommodate one person at a time. These models may work well if you are looking for a private sanctuary, but can be limiting if used in a family or group setting. A variety of different size FIR saunas are available to ensure you can find a model during your sauna selection to accommodate your individual needs.

3: Choose the Location

Measure the location where the sauna will be placed. What are the dimensions of the allotted space and is there an adequate electrical outlet nearby?


Although infrared saunas have far fewer space and electrical requirements than a steam room, there are a few things to think about before deciding on a location and a model. Factors like ease of access, impact on existing location utility, and the view from inside are important to keep in mind.

4: Find the Right Sauna Wood

Infrared saunas can be composed of various types of wood. Durable wood choices like spruce or cedar are premium sauna selections and should be preferred over materials such as plywood. Cedar, in particular is highly resistant to splitting and shrinking. During the sauna selection process this is something to consider for sweating and detoxifying.

5: Understand the Heating System – Ceramic vs. Carbon vs. Both

Ceramic heaters represent the original infrared sauna heater and have been around for many years. They can get much hotter than a carbon heater and have a longer warm up time to reach their optimal temperature. They are also challenged when providing an even room temperature and often create hot or cold areas.  The surface area of these heaters can get quite hot and produce a relatively short infrared wavelength so will not offer as much benefit as a carbon based heater.

Carbon heaters are thin, light, and provide an even and safe surface temperature and they can last up to 50 years! One of the most distinctive features of a carbon heater is its ability to distribute heat evenly throughout the sauna. It heats up quickly (in about 10 minutes) which results in a less expensive energy bill, yet they are not as hot as a ceramic heater when touched.  Carbon heaters produce a longer infrared wave and will be more in tune with the human body.


Each heater delivers pros and cons, but which one is best? Clearlight Saunas® is in the process of patenting the only Carbon/Ceramic infrared sauna heater to offer the best of both worlds. The Clearlight True Wave II infrared sauna heater provides the long beneficial waves of a carbon heater and the high output of a ceramic heater combined into one heater.

Also, make sure your infrared sauna has heaters all around you.  Many companies do not use front wall heaters in their saunas.  All Clearlight Saunas® have heaters on the back wall, front wall, side walls, under the bench, by your calves and in the floor.  You are surrounded by infrared heat.

6: Think Safety

Most FIR sauna users are looking to improve health, making safety an important consideration when deciding what sauna to buy. When purchasing an infrared sauna, it is crucial to consider the Electromagnetic Fields (EMF) and Electric Fields (ELF). The EPA has put in place a 3mG (milligauss) safety limit for EMF levels for human exposure.  Where you are sitting in the a Clearlight Sauna® , the EMF levels are virtually zero.

7: Ensure Quality

Look for the highest quality and craftsmanship possible during your sauna selection process. This will ensure you are making a solid investment in a sauna that is built to last.

Here are a few important quality factors to consider:
• No VOC glues should be used to ensure there is no unhealthy outgassing.
• A timer to monitor your sessions to ensure you are following recommended duration times.
• Kiln-dried/air dried, fine-grain wood construction to minimize warping and cracking and to offer a beautiful look.• An even heat that radiates from all areas of the sauna to ensure a consistent temperature throughout and infrared heat over your entire body.

8: Get an Optimal Warranty

Gather all information about the warranty and what coverage entails. If you are buying from a third party, it may be difficult to get in touch with the manufacturer and the warranty may be limited. Here are a few things to ensure are covered in your infrared sauna warranty.

• Heating System
• Power Supply
• Control Panel
• Wood
• Glass

9: Demand Stellar Customer Service

Consider your FIR sauna purchase an investment. Like any other major purchase, you will want peace of mind in knowing you will be well taken care of if anything happens to go wrong.

Much like the warranty considerations, buying from a third party vendor can leave you without adequate customer service. Be sure that you know where to call with any questions or concerns before you decide to buy.

10: Make it Fun with Customization!

Are you interested in light therapy? How about an audio system? There are a variety of entertainment options that can be added to your infrared sauna to make your experience more exciting and customized to your tastes.

The considerations may seem endless when shopping for the right infrared sauna. Using these sauna selection tips as you start your search can help you make an informed decision in no time! Taking the time to research the specific models, materials, and companies ahead of time will ensure you find a reputable infrared sauna company and the right sauna for you.

Sweating is great for your body. It is not only an organic cooling mechanism and immune response to certain illnesses, but also a means of natural detoxification as it carries heavy metals and other harmful substances out of your system. If you’ve ever wondered where the phrase “work up a healthy sweat” comes from, you can be sure these terrific benefits had something to do with it.

But who has time to run five miles or play a competitive game of hoops every day in order to enjoy the healthful effects of a good sweat? Devoting a couple hours to exercise simply isn’t feasible when work and family commitments constantly vie for your attention, which is why many folks are turning to infrared saunas instead.

Infrared saunas generate heat waves that penetrate deep into the body and produce the same kind of sweat you would experience with vigorous exercise. This means you also derive the same amazing benefits, including the following:

  • Detoxification
  • Weight loss
  • Improved circulation
  • Unclogged pores and better looking skin
  • Stronger immune system
  • Stress reduction

There’s no question that the realities of daily life can interfere with your best intentions and prevent you from doing things you know are vital for your health. But even if you don’t have time to hit the gym as often as you’d like, you can still enjoy the advantages of working up a healthy sweat by spending as little as 15 minutes a day in one of our Clearlight infrared saunas. Visit our website today to discover which home sauna model would be right for you.


While saunas may not be the perfect substitute for a yoga studio, you might be surprised at how much you can actually do – especially in a relatively spacious unit like our Clearlight Sanctuary model. Standing poses or moves that require vertical rather than horizontal movements are obviously easier to perform; but many supine poses may be achieved as well.

Since yoga yields many of the same positive outcomes as heat therapy, going through a short routine in your infrared sauna will accelerate the beneficial results. Depending on your fitness level, yoga program, and length of time spent in your Clearlight unit, these results may include:

  • Increased flexibility and loosening of stiff joints
  • Improved deep-breathing ability
  • Greater weight loss
  • Improved muscle tone
  • Stronger immune system
  • Reduction of stress and heightened capacity for relaxation/meditation

YouTube is a wonderful resource for finding individual hot yoga poses or even full workouts that can be done within the confines of an infrared sauna, so be sure to check out some videos if you want to give this a try at home.

More and more people are realizing that yoga and saunas go hand-in-hand in terms of the healthful, rejuvenating effects they have on the body. From now on, why not combine your workouts and heat therapy sessions into one activity and enjoy superior results.


In the past several years, complementary and alternative medicine (CAM) therapies, including Reiki, meditation, and infrared sauna sessions, have gained tremendous acceptance not only with patients but also with healthcare professionals in virtually all fields. This rising popularity can be attributed to factors such as affordability and safety when compared to traditional drugs and procedures, as well as overall effectiveness.

Although CAM therapies take a number of different forms, here is a brief list of some of the most common treatments used today:

  • Specialized diet: From weight loss to detoxification and disease management, larger numbers of patients are following specialized diets—Atkins, raw food, macrobiotic, gluten-free, vegan—to achieve their health goals.
  • Body manipulation: Based on the belief that mind and body should be in perfect harmony, body manipulation therapies like chiropractic, yoga, and tai chi bring spiritual tranquility in addition to physical relaxation.
  • Sauna: The health benefits of saunas have been thoroughly discussed here on our site. Pain relief, weight loss, detoxification, and stress reduction are just a few of the positive effects of heat therapy.
  • Herbal remedies: More and more people are turning away from prescription drugs in favor of natural herbs to treat their ailments. St. John’s wort, ginger, chamomile, caraway, ginseng, and Echinacea are all widely used.
  • Reiki: Performed by a trained Reiki master, this CAM therapy focuses on restoring energy balance throughout the body by means of light touch on or above specific areas in the head, neck, and elsewhere.

While complementary and alternative medicine therapies are not for everyone, their safety, affordability, and effectiveness make them worth looking into. If you’re currently experiencing health problems or would like to prevent them before they arise, getting an infrared sauna for your home, taking up yoga or tai chi, or changing your diet might be just what you need.
