Infrared vs. Fir Technology: How Are They Different from Each Other? 

Far Infrared Radiation, better known as the acronym FIR, has become increasingly popular as people continue to figure out its benefits. For instance, FIR offers performance-boosting properties, therapeutic properties, and medical effects. There are a wide range of products available that deliver FIR, including heating pads, saunas, and Bright Health’s Red Light Therapy Foot Pain Relief Device. 

Despite knowing that it works, there are still a lot of unanswered questions about FIR technology such as what exactly is it and how does it work? Also, perhaps the most important question is can it help you? Keep reading to discover the answers! 

What is Infrared Energy? 

Far Infrared Radiation takes its place as one of three different classes that make infrared energy. Before we go any further, though, we must develop an understanding of how infrared energy works, as opposed to discussing the purpose of this energy. 

Infrared takes its place as part of the red color spectrum and is an example of electromagnetic radiation. Its wavelength is shorter than microwaves but longer than visible light (700 nm to 1mm). Due to its specific properties, it’s actually invisible to humans in the majority of cases. 

Infrared Energy: How Does it Work? 

Infrared leads to radiation being emitted, which in turn causes motion to occur between molecular bonds. As this motion occurs, energy is naturally released. Anything that radiates heat, has a thermal signature, etc. comes from infrared radiation. 

The Three Parts of Infrared Energy

There are three common energy classifications that were decided upon by the International Commission on Illumination (CIE): far-infrared, mid-infrared, and near-infrared. 

  • Far-infrared waves have the least energy and the longest waves. They have a wavelength between 3.0-100 μm (3,000 nm-0.1 mm). According to the NIH National Library of Medicine, this is the only class of infrared that “transfers energy purely in the form of heat, which can be perceived by the thermoreceptors in human skin as radiant heat.” Far-infrared waves are used in items like heating pads, saunas, and Red Light Therapy Foot Pain Relief Device by Bright Health.


  • Mid-infrared waves have less energy but longer waves than near-infrared. They have a wavelength of 1.4-3.0 μm (1,400-3000 nm) and are used in night vision goggles and heat-seeking missiles.  

  • Near-infrared waves have the most energy and are the shortest. Their wavelengths range from 0.7-1.4 μm (700-1,400 nm). They’re commonly used in items such as fiber optics and TV remote control signals. 

What’s the Difference Between Infrared and FIR? 

FIR and FAR are often used interchangeably, although they don’t mean the exact same thing. Sometimes it gets extra confusing as FIR is occasionally shortened to FAR. There is a difference, though. FIR refers to far-infrared wavelengths, also known as the longest wavelengths. You see, this is due to the fact that FIR is a category of infrared. Meanwhile, FAR is a commonly used abbreviation of Far Infrared or Far Infrared Radiation.

History of Far Infrared Therapy

In the 1980s, NASA scientists were working on the problem of how to grow plants in space. During this time period, the scientists were overjoyed to discover that Far infrared wavelengths that were emitted from LEDs helped their plants grow healthier and faster. 

When they conducted additional research, they found that FIR therapy worked on plants and offered positive effects on the human body. One of its many benefits for humans was that it began to heal skin lesions more quickly. Thus, the groundbreaking FIR infrared therapy was born! 

FAR Infrared Benefits 

You can receive a wide range of benefits from using FAR / FIR technology, including: 

  • Inflammation reduction 
  • Temporary pain relief 
  • Cell regeneration stimulation 
  • Increased blood circulation 

The effects also benefit you by promoting reduced stiffness and pain, faster healing time for injuries, and better overall circulation. 

How is FAR / FIR Used in Red Light Therapy? 

The FSA and HSA approved Red Light Therapy Foot Pain Relief Device is powered by FIR technology. Simply sit down and place your feet on the light device. As soon as your feet connect with the device, you’ll begin receiving therapy that goes below your skin’s surface. This will provide cellular reproduction, oxygenation, cellular repair, and cell stimulation. 

Use the Red Light Therapy Foot Pain Relief Device for:

  • Relaxes muscles, repairs tissues, and accelerates healing 
  • All-natural, drug-free pain solution 
  • Helps with pain from Arthritis, Neuropathy, Plantar Fasciitis, and Tendonitis
  • Enhances recovery from injuries and exercise 
  • Relieves stiffness and general foot pain 
  • Super easy cleanup
