wIRA® - derived from nature

What today is called bionics describes interdisciplinary science, in which methods and systems found in nature are transferred to everyday life; in other words, derived and learned by nature.

From the very beginning, Hydrosun has based its development on findings from nature. Through the development of medical wIRA®, this has been achieved in the best possible way. 

Solar radiation is a prerequisite for the development of life on our earth.
One spectrum out of it is infrared radiation, one of the most natural sources of heat. However, too much solar radiation is harmful. The high infrared portion of the solar spectrum is only tolerable for humans because the radiation is filtered by the earth's humid atmosphere.

This principle was the basis for the development of the hydrosun®-radiators. The light from an incandescent lamp with a spectrum similar to the sun is filtered through a special hydrocuvette, which takes out the radiation components that are harmful to the skin.

It reproduces the interaction of the sun's heat and the filtering effect of the earth's atmosphere. The result is therapeutic radiation in the infrared range, which is characterised by its tolerance and special depth effect: wIRA

Not all infrared is the same

Infrared radiation was discovered in 1801 as a component of the solar spectrum by the english astronomer Sir William Herschel. It is one of the most natural sources of heat and is also called thermal radiation. It stimulates the natural vibration of molecules and is perceived as heat by receptors in the skin.

Infrared radiation is invisible and is historically divided into -A, -B and -C:

Infrared-A   780 nm - 1400 nm

Infrared-B 1400 nm - 3000 nm

Infrared-C 3000 nm - 1 mm

Too much unfiltered infrared is harmful to humans and heat damage can occur. In nature, air and atmospheric moisture filter out infrared-B and -C radiation or at least attenuate it very much.

The long-wave infrared-C is already strongly attenuated in the air and is also absorbed by water. Likewise, infrared-B is largely absorbed by water molecules.

Water is also present in high quantities in our uppermost skin layers. Thus, infrared-B and -C can essentially only heat the uppermost layers of the skin and have a superficial effect without any significant depth effect. The water in the skin forms an impenetrable barrier for them. Infrared B and -C can lead to massive heat stress on the skin surface through absorption.

Only small amounts of infrared-B and a large amount of infrared-A penetrate the skin barrier. But even in the infrared-A spectrum, which is basically well tolerated, a few absorption bands are harmful to the skin. 

To provide deep-acting, skin-friendly infrared radiation for therapy, there are therefore basically two possibilities:

1. To use infrared sources that primarily do not have any skin-damaging components in their radiation spectrum. This is the case with most infrared lasers because they have only one wavelength.
   Their disadvantage is the tiny small size of treatment area.
2. The skin-damaging, only superficially effective spectral components are filtered out of the radiation of an infrared source. The advantage of this method is the ability of an intensive and large-area treatment. 

The method of filtering was used as the basis for the development of diverse hydrosun devices. The sun-like radiation of an incandescent lamp is filtered through a special cuvette, which removes the radiation components that are harmful to the skin. The hydrosun® radiators thus reproduce the described solar atmosphere system, i.e. the interaction of solar heat and the filtering effect of the earth's atmosphere. The result is a deep-penetrating therapeutic radiation in the infrared range (without UV radiation!), which is characterised by its tolerance and depot effect. This can be called medical infrared, as it contains only the therapeutically depth-effective radiation components, while filtering out those components that can cause a burning sensation on the skin or real burns.

The unique hydrosun® radiators are powerful, easy-to-use mobile medical infrared devices that require no connections other than a power socket.

wIRA® shows a much deeper penetration compared to conventional infrared therapy yet it is gentle to the skin. This allows the application with higher intensity, which leads to increased effectiveness.

The hydrosun® single devices are mobile, easily operated medical devices that clearly supersede conventional infrared lamps regarding performance and scopes of application or rather indication.

wIRA therapy may be used in many fields of medicine.
