FIR Rays: What They Are, Benefits and Contraindications

Find out what FIR (far infrared) rays are, how they interact with the human body and what benefits they offer for well-being and circulation.

Origin and History of FIR Rays: From Scientific Discoveries to Modern Use

By breaking down white light with a prism, you get a spectrum of colors from red to violet, passing through yellow, green, blue and various intermediate shades.

In 1800 the physicist William Herschel moving a thermometer over the various projected colors he noticed that even after the red beam the thermometer still showed an increase in temperature. He thus discovered the existence of infrared rays.

In fact, light extends towards the red up to a wavelength of 0.76 μ and from this limit the infrared rays begin. 

Infrared radiation (IR, or Infrared Radiation), also called infrared light or thermal radiation, is between microwaves and visible light. It represents about 56% of the rays radiated by the sun and has long been used in the therapeutic, medical and aesthetic fields.

What are Far Infrared Rays (FIR)?

The infrared spectrum is divided into four bands (or ranges), named with respect to their "distance" from visible red radiation.

But then, what does FIR mean?

FIR (Far Infrared Rays) are a family of electromagnetic waves that are invisible to the human eye but have excellent heating capacity.

The fact that we are talking about “radiation” should not scare you. FIR radiation is naturally emitted by any object or living being that has a temperature above absolute zero, including the human body.

Effects of FIR Rays on the Human Body: Benefits and Mechanism of Action

What happens to the human body when it comes into contact with FIR Radiation?

L'humans cannot see FIR but can perceive it through the skin in the form of heat. The human body, in addition to emitting, can absorb FIR radiation which has been shown to be able to penetrate up to 4 cm deep. This allows it to act on cells and their content, with anti-inflammatory, antioxidant and antimicrobial effects.

These effects manifest themselves in different ways, improving circulation at peripheral and deep levels, promoting the repair and “rejuvenation” of different structures including skin, muscles and tendons. Precisely for this reason they are used in medical therapy and in physiotherapy treatments.

FIR Rays and Health: Are There Any Contraindications? 

In reality, a lot depends on the therapy you choose: treatments with infrared lamps or treatments with FIR (Far Infrared Rays) fabrics.

Infrared Therapy: Differences Between FIR Lamps and FIR Fabrics

• In the first case, that is the infrared lamp, being an energy that transmits heat, must be well measured and calibrated.
  Who can't do infrared?
  Infrared lamp therapy should be used with caution in patients with heart disease and is contraindicated in those suffering from thrombosis, coagulation disorders, lupus, renal failure or if you are particularly sensitive to heat. In any case, it is always advisable for treatments to be followed by expert hands.
• In the case of the infrared fabrics contraindications are practically zero. This is because the FIR Fabric does not emit heat, but rather, thanks to bio-minerals fused inside the fiber, it reflects the same infrared rays that our body produces. Therefore, it is a 100% natural treatment. In contact with the body, FIR fabrics help prevent, control and alleviate certain pathologies. 
  Furthermore, if you take supplements or creams for cellulite reduction, the infrared fabric amplifies their potential. This allows you to have satisfactory results and in less time than a normal treatment.
