|The experience of the pleasant heat of the sun in moderate climatic zones arises from the filtering of the heat radiation of the sun by water vapour in the atmosphere of the earth In contrast to this in the desert the sun is stinging and burning, as the water vapour is missing there in the atmosphere of the earth.
The filter effect of water attenuates those parts of infrared radiation (most parts of infrared-B and -C and the absorption bands of water within infrared-A), which would cause – by reacting with water molecules in the skin – only an undesired thermal load to the surface of the skin.
Due to the filtering effect of water typical wIRA radiators emit nearly no infrared-B and -C radiation and have decreased water absorption bands within infrared-A.
In contrast to the sun typical wIRA radiators emit no ultraviolet (UV) radiation, the amount of infrared-A (wIRA) radiation in relation to the amount of visible light is emphasized (e.g. approximately 75% wIRA).
This results in: good penetration properties of wIRA into tissuewith low thermal load to the skin surface.
This allows: compared to unfiltered heat radiation – a multiple energy transfer into tissue without irritating the skin.
|wIRA is used in wound healing, skin diseases, oncological hyperthermia, pain therapy, poor peripheral circulation, and in the treatment of chronic inflammation and musculoskeletal pain.
|Unique features of wIRA
No overheating of superficial skin layers
- No dehydration of the skin
- Deep penetration and improved circulation in deeper tissues
|The technique of wIRA
Technically water-filtered infrared-A (wIRA) is produced in special radiators, whose full spectrum of radiation of a halogen bulb is passed through a cuvette, containing water, which absorbs or decreases the described undesired wavelengths of the infrared radiation.
Production of a therapeutically usable field of heat in the tissue:
Three vital factors for a sufficient tissue supply with energy and oxygen (decisive for processes of regeneration and healing, e.g. of hypoxic wounds)
- oxygen partial pressure and
- perfusion in the tissue
Based on putting direct stimuli on cells and cellular structures.
Non-thermal effects have been described especially of the energy-rich wavelengths near to visible light - approximately 780-1000 nm - both in vitro and in vivo, and these wavelengths seem to represent the clinically most important part within infrared-A and wIRA.
This could lead to improved cell regeneration and wound healing and to antibacterial effects and to infection prevention.
|Clinical effects of wIRA
wIRA can show:
- pain (and required dose of analgesics)
- positive immunomodulatory effects
|Clinical application of wIRA
The typical heat applications (preventive, therapeutic, regenerative, rehabilitative)
Physical therapy / Sports medicine / Orthopedics: Myogeloses, lumbalgia, Ankylosingspondylits (Bechterew disease), arthritis, tendonitis; fibromyalgia, regeneration after sport activities (wIRA also in combination with physical activity: wIRA + cycle ergometer)
General medicine / Rheumatology: Chronic inflammations, chronic degenerative-rheumatic illnesses, pain treatment: Muscle pain, neuralgias, muscular cephalgia, lumboischialgia.
ENT medicine e.g.
- Chronic remitting nasal sinusitis
- Otitis media
- Otitis externa
- Maintenance of the body temperature, "heat depot" before transportation
- Heat source at baby changing facilities, resuscitation units and during the care in incubators
|Based on 6 clinical studies, the following has been proven with a level of evidence of 1 a/b:
Clinical effects of wIRA on wounds
As a trend the following has been found:
- Acute pain reduction during wIRA irradiation
- Reduction of the required dose of analgesics
- Faster reduction of wound area
- Better assessment of wound healing
- Better overall evaluation of the effects of irradiation (including pain, wound healing, cosmesis)
- Higher tissue oxygen partial pressure during wIRA
- Higher subcutaneous temperature during wIRA
- Better cosmesis
- Lower rate of wound infections
- Shorter postoperative hospital stay
- Reduction of inflammation
- Reduction of hypersecretion
