Full Spectrum Infrared Sauna

Health Benefits

In our infrared saunas, the average person sweats out 20% toxins and 80% water, while in a conventional sauna, the average person sweats out 3% toxins and 97% water.

Weight Loss

As the body works to cool itself while using an infrared sauna, there is substantial increase in metabolic rate. Use the sauna with exercise to reduce recovery time and increase results.


With the infrared heat found in Solocarbon ® heating technology, our saunas are guaranteed to help you relax with an invigorating sweat that will have you feeling stress free with each session.

Improved Circulation

Blood flow during infrared sauna use has been reported to rise from a normal rate of 5-7 quarts per minute to as much as 13 quarts per minute.

Frequently Asked Questions (F.A.Q.)

Are children allowed to use the sauna? What should I consider with this?

The core body temperature of children rises much faster than adults. This occurs due to a higher metabolic rate per body mass, limited circulatory adaptation to increased cardiac demands and the inability to regulate body temperature by sweating. While you may choose to allow it in personal settings, Fox River Spa does not allow children under the age of 17 to use the sauna.

Is it ok to use the sauna while breastfeeding?

Please consult with your physician, as this answer is usually yes, but may be no depending upon your specific circumstances.

What should I wear in the sauna? Can I go nude?

You can go nude if you would like, but be sure to put down towels to absorb your sweat. Men typically wear workout or swim trunks; women typically wear a swimsuit or workout shorts and a tank top or sports bra. You may also wrap yourself in a towel or robe and use the sauna that way. Going nude vs. wearing light clothing will not alter the effectiveness of your sauna session.

What time of day should I use the sauna (am or pm)?

It is completely up to you and your lifestyle. There is no data showing more of a benefit in the morning or evening.

How do you keep the saunas clean?

We use an all-natural sauna cleanser and sanitizer after every guest and wipe down all surfaces with Sunlighten’s approved product. Infrared saunas are generally maintenance-free and easy to keep clean with this routine.

How long is a typical session? And how often can I take a session?

Most people partake in a 30-45 minute session, 3 -4 times a week, but it is safe to use every day and at whatever heat suits you best.

What health benefits are associated with infrared heat, and which have been proven and documented?

All of Sunlighten’s health benefits have been either clinically shown on our heaters or are based on studies of infrared wavelengths that are precisely mimiced in their heaters. Sunlighten saunas are proven up to 99% effective at emitting the highest quality and quantity of infrared heat required for delivery a full range of health benefits.

What is EMF? Is it harmful to the body?

EMF (electric and magnetic fields) are waves of electric and magnetic energy radiating through space. High EMF levels are often associated with power lines. EMF is everywhere in our homes and offices. The electrical appliances we use (an electric can opener at close range emits substantial EMFs), computers, monitors, keyboards and mice, wireless modems, cordless phones, clock radios, hair dryers, mobile phones, microwave ovens and more – all produce EMFs.

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 that reason, we have limited the levels of EMF from our heaters as much as possible. If you are concerned at all about EMF, our Signature and Solo contain our Ultra Low EMF Solocarbon heaters. Our exclusive manufacturing process allows us to cancel out EMF to levels that are virtually undetectable.

What is the difference between ceramic and carbon infrared technology?

Both technologies are ways to deliver infrared heat, but ceramic rods have now been surpassed by carbon panel technology thanks to the latter’s ability to produce a more consistent infrared output at lower temperatures given its surface area. Ceramic rods must be brought to excessively high heats, resulting in hot and cold spots throughout your sauna. All Sunlighten saunas use carbon-based technology, and in fact, are the only carbon-based heaters with clinical backing.

Does infrared technology interfere with implants (metal, silicone, etc.)?

Metal pins, rods, artificial joints or any other surgical implants generally reflect infrared waves and thus are not heated by this system. Nevertheless, you should consult your physician prior to using an infrared sauna.
