Far Infrared VS Full Spectrum Saunas

Why Far Infrared is the Superior Choice

In this article, we take a deep dive into the details and explain why we made the decision to discontinue our full-spectrum saunas in order to focus exclusively on Far Infrared (FIR) saunas. Infrared (IR) therapy has gained widespread attention for its potential health benefits, particularly in areas such as pain relief, improved circulation, and detoxification. Within the IR spectrum, there are three primary categories: Near Infrared (NIR), Mid Infrared (MIR), and Far Infrared (FIR). While full-spectrum infrared therapy claims to incorporate all three, the reality is that most of the benefits come from Far Infrared (FIR), making full-spectrum infrared more of a marketing gimmick than a truly superior product.

Full Spectrum: A Marketing Ploy?

The concept of "full-spectrum infrared" is often used as a marketing tool to justify higher prices on infrared saunas and devices. However, research overwhelmingly supports Far Infrared (FIR) as the most beneficial and scientifically backed form of infrared therapy. Near Infrared (NIR) and Mid Infrared (MIR) have limited penetration and efficacy in comparison to FIR, with many of their supposed benefits being anecdotal or exaggerated by manufacturers.

1. Most Benefits Come from Far Infrared
   The majority of studies on infrared therapy focus specifically on Far Infrared Radiation (FIR) due to its deep tissue penetration and ability to promote circulatory, metabolic, and cellular benefits (Vatansever & Hamblin, 2012). Despite claims that full-spectrum infrared is "more complete," the reality is that most of the clinically proven benefits come exclusively from FIR.

2. Near and Mid Infrared Have Minimal Additional Benefits

   • Near Infrared (NIR) is often associated with skin-level benefits, such as light therapy for wounds, but in infrared saunas, NIR is typically not intense enough to produce these effects.

   • Mid Infrared (MIR) has slightly deeper penetration than NIR, but it does not compare to FIR in terms of therapeutic effectiveness.

   • The added presence of NIR and MIR in "full spectrum" devices is more about marketing than meaningful health improvements.

3. Full Spectrum Infrared Tends to Have Higher EMF Levels
   Another major downside of full-spectrum infrared saunas and devices is their higher electromagnetic field (EMF) emissions. Many full-spectrum models incorporate multiple heat sources and emitters, which increases electrical interference and EMF exposure.

   • Studies suggest that prolonged exposure to high EMF levels may lead to cellular stress, inflammation, and potential health concerns.

   • FIR saunas, on the other hand, are often designed to be low-EMF, making them a safer and more effective option (Chiang et al., 2017).

4. No Harmful UV or Blue Light Exposure
   Unlike full-spectrum devices that may emit low levels of UV or blue light (potentially harmful to the skin and eyes), FIR completely eliminates these risks, making it a safer, non-invasive therapy (Itakura et al., 2003).

The Proven Benefits of Far Infrared

1. Deeper Penetration & Cellular Effects
   Far Infrared wavelengths (3-100 μm) penetrate the skin and tissues more effectively than near or mid-infrared wavelengths. FIR therapy stimulates microcirculation, promotes cellular repair, and enhances mitochondrial function, making it particularly useful for chronic pain, inflammation, and recovery (Vatansever & Hamblin, 2012).

2. Safer and More Targeted Than Full Spectrum
   Unlike full-spectrum infrared, which includes near and mid-infrared, FIR emits heat without excessive surface heating. This makes FIR saunas and therapy devices safer and more comfortable, especially for individuals with sensitive skin or heat intolerance (Gruyter & Infrarotstrahlung, 2012).

3. Proven Medical Applications
   FIR has been successfully used in various medical fields, including:

   • Cardiovascular Health: FIR improves blood flow, reduces hypertension, and enhances vascular function (Lin & Lin, 2021).

   • Detoxification: FIR promotes sweat-induced detoxification, assisting in the elimination of heavy metals and toxins.

   • Pain Relief & Inflammation Reduction: FIR therapy significantly reduces muscle and joint pain and is being used in arthritis and fibromyalgia treatments (Chiang et al., 2017).

   • Wound Healing & Skin Health: FIR enhances collagen production, accelerates wound healing, and improves skin elasticity (Pastore et al., 2020).

Conclusion

While full-spectrum infrared therapy is marketed as "more complete," it is largely a gimmick designed to upsell infrared therapy products. The scientific consensus overwhelmingly supports FIR as the most effective and well-researched form of infrared therapy. With proven health benefits, lower EMF exposure, and superior safety, Far Infrared Radiation (FIR) remains the gold standard for infrared therapy, offering real therapeutic advantages without unnecessary marketing hype.
