For years, the healthcare industry recommended infrared heat lamps as a source of infrared therapy, but the lamps were cumbersome, dangerously hot, and difficult to maintain at a constant temperature. Today, many healthcare professionals use a new generation of infrared heaters to treat a variety of diseases throughout the world.

How Does Far Infrared Therapy Work?

Infrared is the longest wavelength of light energy, and can penetrate deep into the body to activate sweat glands. Since sweat is one of the few mechanisms the body has to get rid of toxins, and the skin is the largest organ in the human body, use of infrared energy is a very effective means for the decontamination of the body.

When far infrared waves are applied to water molecules (which make up to 70% of our bodies), the molecules begin to vibrate. This vibration weakens ionic bonds, and the eventual breakdown of the water molecules causes encapsulated gasses and other toxic materials to be released. Far infrared energy can also penetrate fat cells causing vasodilation.

As fat cells vibrate, they expel toxins, resulting in greater levels of decontamination, while causing significant metabolic stimulation that can aid in weight loss.


Infrared therapy is low temperature therapy. Infrared saunas use carbon/ceramic to produce invisible, far infrared heat. Infrared heat is very safe (depending on which sauna brand you choose), and not at all like the heat produced by microwaves. In an infrared sauna, 20% of the energy is used to heat the air, while the rest works directly on heating the body. This radiant heat penetrates deep below the skin, producing a gentle, gradual warming of the body’s core temperature.

The temperature inside a far infrared sauna is adjustable and averages a comfortable 100°F to 135°F. These lower temperatures allow you to sweat faster and tolerate a longer sauna session, enabling greater therapeutic benefit. A typical infrared sauna sessions last 20 to 45 minutes and can be repeated throughout the week to maximize the benefits. Infrared saunas leave you feeling invigorated, not depleted like conventional saunas.

The Fever Effect

The goal of every infrared sauna session is to imitate the practical effects of a “fever” that can deliver a healthy, deep decontaminating sweat at the cellular level (where the majority of toxins reside) in order to dissolve harmful substances and drive them to the surface via sweat for easy elimination. You can literally ‘sweat out’ toxins, and wash them off afterwards. But there’s more to it than that.


One of the keys to effective detoxification in an infrared sauna is warming your body and raising your core body temperature. You want to find a sauna that heats both the back and front of your body. Many saunas on the market today leave the front heaters out or have very small front heaters for aesthetic reasons. This is a mistake; you simply cannot effectively detox in an infrared sauna without warming your front body core.

Some brands will needlessly run their heaters close to the ceiling. As we all know, heat rises. There is no need to heat the cabin air above your head, unless you plan to stand on the bench. High quality, effective infrared heaters are designed specifically to heat the body. Look for a sauna that has heaters installed in close proximity to where the body will be sitting, such as on the front wall, back wall, side walls, underneath the bench, close to your calves and in the floor.

Some heaters on the market consist of a single, thin rod in front of a metal reflector. Generally, these heaters produce lower-quality, far infrared heat when compared to a large flat-panel far infrared heater. The single-rod heater must run at a much higher surface temperature than a large, flat radiant heater to produce sufficient infrared heat. As an interesting (and potentially shocking) side note, many such heaters were designed to cure paint in industrial settings.

With carefully placed, high efficiency far infrared output (emissivity) of heaters like those found in Jacuzzi® Infrared Saunas, you not only get the highest quality infrared heat, but you get a lot of it—right where you need it.

“Our Clearlight Sauna has been a game-changer for surviving Wisconsin winter! It has become a daily post-workout ritual of stretching and re-centering. Best purchase of the year. Thanks to Jen Rudis at Jenerate Wellness. Can’t say enough about the awesome customer service both pre-delivery and for post-delivery set-up help.”
