The infrared spectrum is divided into three regions: near-infrared, intermediate-infrared, and far-infrared. The borders between the near-infrared, mid-infrared, and far-infrared sectors are not well-defined and can shift. The type of detector technology used to gather infrared light is the major component that decides which wavelengths are included in each of these three infrared areas.
The visible and microwave sections of the electromagnetic spectrum are separated by infrared light. The wavelength of infrared is similar to visible light whereas, the wavelength of far-infrared is near to microwaves in the spectral region.
In short, far-infrared light is the region of the infrared spectrum.
We are constantly exposed to infrared radiation in the form of heat! Infrared is the heat we feel from the sun, a fire, a radiator, or a heated sidewalk. The temperature-sensitive neuron endings of our skin can feel the difference between our body’s internal temperature and the outside temperature of the skin.
Infrared light is utilized to heat food in some cases; fast-food restaurants frequently employ special lights that create thermal infrared waves!
The section of the electromagnetic spectrum that extends from the long-wavelength or end of the visible-light range to the microwave region is known as infrared radiation. It is undetectable to the naked eye, but it can be felt as a warm sensation on the skin.
Infrared radiation is a form of electromagnetic wave that is produced when atoms absorb and then release energy in a continuous range of frequencies. Electromagnetic radiation includes gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves, from highest to lowest frequency. The electromagnetic spectrum is made up of all of these different types of radiation in a spectral region.
According to NASA, an experiment is performed in which thermometers are placed in the path of light rays within each color of the visible spectrum to measure the difference in temperature between the colors. The researcher noticed a shift in temperature from blue to red, and he discovered an even warmer temperature reading just beyond the visible spectrum’s red end.
How can we see infrared rays?
Heat or thermal radiation is the major source of infrared radiation. Infrared rays are also emitted by extremely cold items. When an object isn’t hot enough to emit visible light, it emits the majority of its energy in the infrared spectrum. For example, hot charcoal does not emit light but does emit infrared radiation, which humans perceive as heat.
Far-infrared (FIR) is a region of electromagnetic radiation in the infrared spectrum. Far-infrared is commonly described as any radiation having a wavelength of 15 micrometers to 1 millimeter (equivalent to a range of around 20 THz to 300 GHz), which falls within the CIE IR-B and IR-C bands. These FIR electromagnetic radiations are introduced in therapy devices available at Healthy Line to provide comfort and reduce pain.
What does Far-infrared do?
Far-Infrared Rays are invisible to the naked eye waves of energy that penetrate the skin’s surface and gently raise the body’s surface temperature to 107.6F/42oC and above, while positively activating physiological systems and functions.
Because far-infrared is absorbed primarily by water in our bodies, it hardly penetrates 0.1mm beneath the skin. FIR light can cause changes to the body’s protein structures despite being absorbed by the body’s water.
Health benefits of Far-infrared rays
Far-infrared radiations have many benefits to improving a healthy lifestyle by enjoying a therapy session from FIR devices available at Healthy Line:
· Arrhythmias in those with chronic heart failure are being reduced, while blood vessel health indices in people with heart attack risk factors are improving.
· Reducing rheumatoid arthritis and ankylosing spondylitis patients’ pain and stiffness
· Provide recovery from type 2 diabetes and improve the quality of life
In this article, we have explained the difference between infrared rays and far-infrared rays. Both are in the same range of electromagnetic spectra and provide relief from various health issues.
