Hungarian and German scientists have demonstrated in studies that direct irradiation of the nasal mucosa with a combination of ultraviolet and visible light significantly relieves hay fever symptoms such as sneezing, itching, and runny nose. The study involved 49 patients who were allergic to pollen from mugwort.
Treatment with UV light
For 21 days, patients were irradiated three times a week with a light source inserted into their nostrils. The radiation dose was five percent UV-B radiation, 25 percent UV-A light, and 70 percent visible light. During treatment, the dose was slowly increased and significant improvement in symptoms was noted.
Similar to UV-free light therapy, overactive immune cells and inflammatory cells are killed. Because direct irradiation of the nasal mucosa does not interfere with the patient’s metabolism like a drug, this procedure could be used especially in pregnant women and children.
Light on – fat off ?
Lasering instead of fasting: the research results of scientists at Massachusetts General Hospital in Boston hold out the prospect of a corresponding procedure. There, they have succeeded in heating fatty tissue with the help of infra-red laser radiation without damaging the overlying skin layers. Because fatty tissue is heated faster than water at certain infra-red wavelengths, the body can break down and eliminate the fat. This opens up new perspectives for the treatment of severe acne, cellulite or arterial sclerosis. However, it will likely be some time before the technology is ready for widespread use.
Cost coverage
Certain forms of light therapy are paid for by statutory health insurers if they are prescribed and performed by a panel physician. Also, as part of a case-by-case decision, the rental or acquisition costs incurred for certain devices may be covered by health insurance. In these cases, a corresponding, medically justified application must be submitted to the relevant health insurance fund before treatment begins. A discussion with the treating physician and the health insurance company is worthwhile in any case.
