Understanding Far-Infrared Radiation
Before delving into its applications, it’s crucial to understand what far-infrared radiation is and how it interacts with the human body. Far-infrared is a type of radiant heat that penetrates the skin more deeply than conventional heat sources. It’s often described as a form of energy that resonates with the body’s own heat signature, potentially leading to various physiological effects.
The wavelength of far-infrared radiation typically ranges from 3 to 100 micrometers, with the most effective for biological purposes being between 4 and 14 micrometers. This radiation can be emitted by specially designed materials or generated by natural sources like the sun.
When far-infrared energy is absorbed by the body, it may cause a phenomenon known as “resonance absorption,” where the energy is thought to interact with water molecules and organic compounds in our tissues. This interaction is believed to produce a range of effects, including increased blood circulation, reduced inflammation, and improved cellular metabolism.
