Is a Far Infrared or Full Spectrum Sauna Best?


Wellis New England’s selection of Clearlight Saunas come in either far infrared or full spectrum sauna models. Deciding which kind is best for you depends on what you are trying to accomplish in your sauna sessions. The key is to be very specific about what physical conditions or ailments you want to address so that you can research the saunas before making a purchase.

Here, we give an in-depth description of how both far infrared and full spectrum saunas work, as well as how to best put them to use.

Far Infrared or Full Spectrum Sauna. What’s the difference?

The terms “far Infrared” and “full spectrum” refer to levels of infrared heat emitted inside your sauna to make it warm. In order to understand the difference between the two, we need to cover some basics.

Infrared heat is categorized by three levels:

  • near infrared
  • mid infrared
  • far infrared

Each one penetrates the skin to a different degree. As a result, different physical conditions are targeted at each level. An easy way to think of it is like this:

  • near infrared = deep
  • mid infrared = deeper
  • far infrared = deepest

A far infrared sauna, as its name suggests, only emits far infrared heat. A full spectrum sauna, on the other hand, emits all three levels of infrared heat (i.e., near, mid, and far). 

The Benefits of Infrared Heat

According to the National Institute of Health (NIH), these different combinations of infrared heat in saunas promote a wide variety of wellness goals. It all comes down to how your many physiological systems respond to the different wavelengths. The important thing to remember is that each wavelength, be it near, mid, or far, is still within a range that is safe for the human body.

Far Infrared Sauna Uses

Far infrared saunas are the best fit for wellness goals that aren’t tied to a severe health condition. They stimulate detoxification, weight loss, boosted immunity, reduced blood pressure, better circulation, and improved cardiovascular health. 

Heat in a far infrared sauna is good at penetrating your body’s soft tissue and, thereby, raising your core temperature. This begins a chain reaction in which the heart rate increases, profuse sweating occurs, and your circulation improves. You, ultimately, create a response in your body similar to the one you would experience through a moderate jog. 

Full Spectrum Sauna Uses

Full spectrum saunas are unique in that they emit near, mid, and far infrared heat all at once. This means that in addition to the far infrared benefits listed above, full spectrum saunas can be good for localized pain relief, cell health, skin renewal, and wound healing.

Adding near infrared heat to the mix is this sauna’s super power. Every cell in our body contains a structure called the mitochondria (a.k.a., “the powerhouse of the cell”). All of our bodily functions rely on them working at full capacity. Lazy or fatigued mitochondria result in dysfunctional systems that many experts argue contribute to conditions like heart disease, Alzheimer’s disease, autoimmune disorders, arthritis, thyroid and/or adrenal imbalances, and even lingering athletic injuries.

However, surrounding the mitochondria are tiny photoreceptors. When exposed to near infrared heat, these receptors cue the mitochondria to pump more oxygen into your bloodstream. These re-energized mitochondria, then, help reverse the damage in the system and, thus, ease the severity of symptoms.

Far Infrared or Full Spectrum Sauna: What will you choose?
