As a non-invasive method for alleviating allergic rhinitis, there has been a recent ongoing research in the treatment of light from light emitting diodes (LEDs) and lasers. A total of 15 subjects diagnosed with allergic rhinitis were selected for this study. Red and near infrared light emitted from LEDs with wavelengths of 660nm and 940nm were illuminated three times daily (three minutes per cycle) for a total of two weeks. The degree of nasal congestion, runny nose, sneezing and nasal itching was evaluated by questionnaires before and after the test. Also, the serum IgE (Immunoglobulin E) was measured and compared before and after the test. As a result, the total score of symptoms of allergic rhinitis was decreased by 67% after the test (P<0.01). The level of IgE was decreased by 17% after the test (P<0.05). In conclusion, the non-invasive LED phototherapy method using red and near-infrared LED light was effective in alleviating symptoms of allergic rhinitis. There were no adverse effects or complications reported during and after the test.
