| There is a lot of conflicting information regarding FIR. People  who sell space heaters, saunas, and medical devices are all making claims that  their product produces far infrared rays. Here, we will try to clarify and  remove the confusion about infrared wavelengths and classifications. This will  make it easier for you to make an informed decision when you get ready to  purchase a product that produces far infrared rays.   First, we need to understand that the infrared spectrum is  invisible to the human eye.  Therefore,  if you can see the ray, that is not infrared. There might be invisible rays  combined with visible rays, however any ray you are able to see with your eyes  is not infrared.  Every object including animals to minerals can radiate  infrared as long as its temperature is over absolute zero. Infrared is produced  from a campfire, a glowing heating element in a space heater, or the glow from  simple light bulb. However, these either do not produce biological grade far infrared  rays, or there are simply not enough far infrared rays to benefit the human  body. To truly get concentrated far infrared rays, use specially designed  products like the Crystal Rays Mats. Crystal Rays products in particular,  are designed to emit the beneficial biological grade far infrared spectrum at high  concentrations. When researching about far infrared online, you need to be  aware of a few things. First, there are  no two organizations that define infrared the same. This does not mean that  there is no true information regarding infrared out there; it means, rather,  that you will have be diligent in your research and carefully read what is  written. The International  Commission on Illumination (CIE) is one of the most well recognized organizations which define infrared as  narrow wavelengths. Additionally, most white papers in the study of  human or animals and infrared, show that FIR is the most active between 3-12  micrometers. Please be aware that the CIE is not the only organization that defines Infrared.  Others have defined infrared differently than the  CIE. Examples include: the Astronomy division scheme, the ISO  20473 scheme, the Sensor response division scheme, and Telecommunication bands  in the infrared – which could be controlling you television’s remote control.   The key to understanding infrared is the wavelength.  So when reading websites, books, or clinical  studies, the mere mention of infrared, far infrared, or mid infrared is not a true indicator of whether  biologically active far infrared is being produced. (These terms are often used  for sales, search engine, and metadata search results to drive traffic to their  products.) You must know what wavelength is being produced and studied. For without the all-important wavelength data, it is impossible to know if you are  looking at a product that produces biological grade, far infrared rays  which can greatly benefit the human body.  NASA white papers define infrared differently than the CIE. NASA defines mid-infrared as 5 (25–40) µm, using the Astronomy  division scheme. When contrasted  with CIE standards, NASA’s definition of “Mid-Infrared” is clearly biological  grade far infrared, not mid-infrared as  shown earlier on our chart.  So, which is correct? The truth is that both are correct. They both notify  the reader of the wavelength they are using.   It is the wavelength that is important, not the classification. When  looking for biological grade infrared, realize that only a few inches or  centimeters from the source defines this wavelength.   When buying products that emit infrared rays,  understand that wavelength defines what the device is able to deliver. However,  there is much more to consider than just wavelengths.  |  |
