Hydrosun Irradiator

The Hydrosun Irradiator reproduces the combination of the sun and the humid atmosphere.

Without producing ultraviolet rays, its emission lies in the deep penetrating area of infrared-A with wave-lengths from 0.78 to 1.4 micrometers.

The water-filtered infrared-Aradiation of the hydrosun® Irradiator allows a locoregion al heating of human tissue with a higher penetration depth than that of convention al infrared therapy.

The unique principle of operation involves the use of a hermetic ally sealed water filter in the radiation path to absorb those infrared wavelengths emitted by conventional infrared lamps which would otherwise harm the skin.

This absorption results of the activation of the OH-groups at 940, 1180, and 1380 nanometers.

Hence, with the higher radiation intensity, therapeutic heating of deeper tissue layers over longer periods of time can be achieved.

Since with the application of heat therapy in the area of physical medicine an improved blood circulation in deeper tissue layers is desirable to increase meta -bolism and to wash out metabolites.

Working mechanisms of WIRA water-filtered infrared-A

WIRA acts both by thermal effects as well as by non-thermal effects. The production of a therapeutically usable field of heat in tissue and the energy-related aspects derived from this belong to the thermal effects of WIRA.

As an effect related to the transfer of heat radiation energy to tissue WIRA produces a therapeutically usable field of heat in tissue by:

  • Reaching capillaries of the skin by the infrared-A radiation (primary warming)
  • Heat distribution by the blood (cooling of tissue areas near the surface of the skin, spreading of the eat into the depth)
  • Increasing capillary blood-flow with expansion of the blood flow areas accessible to the radiation and by this augmenting the second mechanism
  • Conduction of heat into the depth
  • Secondary energy release by stimulation of metabolism (increase of metabolism) caused by the increase of temperature (in accordance with the reaction velocity temperature rule a 3°C higher temperature means approximately 30% more speed of reaction and by this more energy provision and release in the tissue)
  • Relatively high primary depth effectiveness of WIRA.

Research showed that WIRA, apart from the temperature, considerably increases the oxygen partial pressure and the blood flow in tissue – two factors which are crucial for an improvement of wound healing as well as for infection defence. Remarkable pain relief could be observed.
