The Ultimate Guide to Red Light Therapy
Another study used a combination of visible and infrared light, applied directly inside the nose, to treat 22
patients with confirmed allergic rhinitis over a four-week period.
27
To track the effectiveness of the treatment,
patients filled out weekly questionnaires about their symptoms.
The researchers also collected samples of nasal fluid before and after the treatment course.
27
These samples
were analyzed using a sophisticated technique called fluorescence-activated cell sorting, which allowed
them to count specific types of immune cells involved in allergic reactions.
After four weeks of treatment, patients reported significant improvements in various symptoms, including
itching in the nose, eyes, throat, and ears, as well as reduced nasal discharge, congestion, and sneezing.

While these findings suggest that intranasal light therapy could be an effective treatment for allergic rhinitis,
leading to noticeable symptom improvements, the changes in immune cell populations warrant further
investigation to fully understand the mechanism behind these effects.
