FIR Real: The Sauna Truth You Need to Know

Why We Only Use FIR—and You’ll Be Glad We Do

Ever seen a sauna advertised as “full spectrum” and thought, that must be better, right? Not quite. At Local Motion, we’ve researched and switched to 100% Far Infrared (FIR) saunas. Here's why you’ll benefit from this choice.

What’s a Full Spectrum Sauna?

A “full spectrum” sauna includes three types of infrared light:

• Near Infrared (NIR) – Short wavelength, mostly used in red light therapy.

• Mid Infrared (MIR) – Medium wavelength, penetrates a bit deeper than NIR.

• Far Infrared (FIR) – Long wavelength, penetrates deep into muscles and joints.

  
  

What it looks like: Most full spectrum saunas have multiple light panels. Some emit a visible red or orange glow (NIR), while others provide warmth (FIR). They look impressive, but the extra lights don't always deliver additional benefits.

The Advantages of FIR Saunas

Far Infrared is the MVP of sauna therapy. Here’s what science shows about FIR:

• Deeper penetration: FIR waves penetrate 3–5 cm into the body, reaching muscles, joints, and even organs.

• Boosts circulation: FIR helps blood vessels expand, increasing oxygen flow.

• Fights inflammation: FIR is effective for chronic pain, arthritis, and post-workout soreness.

• Encourages detoxification: FIR promotes sweating, helping to flush out heavy metals and toxins.

• Improves skin health: FIR stimulates collagen, enhances elasticity, and speeds up healing.

Understanding Red Light Therapy (Near Infrared)

Red light therapy is beneficial but works best with focused, high-intensity devices, not diluted in a sauna.

• NIR targets the surface of the skin, providing benefits such as:

- Wound healing

- Improved skin tone

- Acne treatment

• In a full spectrum sauna, the NIR lacks the strength and direct focus needed to deliver the same benefits.

  
  

Bottom line: If you want red light therapy, it’s best to use the proper technology separately for optimal results.

Addressing EMFs in Saunas

EMF = Electromagnetic Fields. These are invisible energy waves that come from electrical devices—like your phone, microwave, or some saunas.

• Full spectrum saunas often have higher EMF output due to multiple light sources and complex wiring.

• High EMF exposure can lead to:

- Cellular stress

- Inflammation

- Sleep disturbances

- Headaches and fatigue, especially for sensitive individuals

Far Infrared saunas can be designed with low-EMF technology, making them significantly safer for regular use.

Why We Prefer FIR

• Scientifically supported: FIR is backed by research, not just marketing hype.

• Deeper healing: FIR effectively treats muscles, joints, and reduces stress.

• No unnecessary features: FIR saunas avoid gimmicks and superfluous light shows.

• Low EMF exposure: A safer option for regular sauna use.

• Multi-faceted benefits: FIR supports recovery, improves skin health, promotes detoxification, and enhances mood.

  
  

Bottom Line: While “full spectrum” sounds impressive, it often serves more as a marketing gimmick. Far Infrared does the heavy lifting safely and effectively, delivering genuine benefits that you will notice.
