Far Infrared is 100% natural

Far Infrared is radiant heat which we ourselves as human beings naturally emit. This is the same heat we feel from an environment warmed by the sun.  It is completely natural and 100% safe.

Human & animal sense of comfort has evolved from radiant heat from the sun. Our skin naturally tans, reflects and prompts us to avoid the suns hottest waves in the hundreds to thousands of degrees Centigrade – called Middle and Near (or Medium and Shortwave) infrared. The waves we find most comfortable are those that are absorbed by our environment and radiated back in the tens of Degrees Centigrade – called Far (or Longwave) infrared.

It is no surprise that it is Far Infrared that our skin and common materials in our environment absorb and emit the most efficiently and 100% naturally.

 

Human body's sensitivity to radiant heat

Radiant heat is biologically the most significant (60%) to our body’s sense of comfort. Convection (movement of hot or cold air) represents only 15% of our feeling of comfort, with evaporation and conduction of heat from our bodies to our clothing or other objects accounting for the remaining 25%.

We’re most sensitive to radiant heat from the top of our bodies downwards (no surprise in evolutionary terms) and we also radiate it back out most readily towards the top of our bodies too.

Far infrared is the most significant wavelength for us biologically, because it is the wavelength most efficiently absorbed by the water in our skin. The 8 – 12 micron waveband of the Far Infrared is often referred to as the “Vital” range because of its vital warming properties, of human comfort and biological significance, and used elsewhere in baby incubators and in the wellness industry.

Far Infrared is not:

  • Ultraviolet. Ultraviolet is a photochemically altering wavelength from the sun in the high energy side of the Electromagnetic spectrum before the visible colour Blue.
  • Microwaves. Microwaves are a longer wavelength, higher amplitude part of the Electromagnetic spectrum posessing very different physical properties from Far Infrared.
  • “Electro-Smoggy”. Resistance-based heaters form the lowest category of electromagnetic emitters of any electrical devices.
Condensation on a window

Far Infrared reverses the conditions necessary for damp to form in a building. It warms up walls and it doesn’t warm up the air. (Convection heaters do the opposite: they warm the air and don’t warm the walls. Perfect conditions for condensation to form.) This Far Infrared environment is also very beneficial for health, because dampness forms a breeding ground for mould, fungus and other bacteria that contribute to the causes of ill health.  Far Infrared produces a warm, dry environment.

Far Infrared is also non convective, meaning it does not, in itself, create air flows within a house which convection heaters by their very nature (movement of warm air) do. Intrinsically wasteful of the heat (which rises upwards), convector heaters encourage the movement of damp, dust and airborne allergens, as well as creating layers of uneven warmth in a house, all of which contribute to ill health.

The preferred wavelengths for comfort heating

Heat absorbtion of water Water – which comprises 80% of human and animal skin absorbs most efficiently from 3 microns and lower which is Far Infrared (longwave). This implies both people and animals can be warmed effectively and comfortably and effectively by the correct use of Far Infrared, not Shortwave (Tungsten Halogen) or Medium wave IR (Quartz).
