Rhinitis, the most common type of respiratory allergies, affects 10 to 25% of the world population. The symptoms include nasal obstruction, nasal discharge, sneezing, itching in the nose, throat and eyes. There are two types of rhinitis: perennial and seasonal. The perennial is deflagrated by different environment allergens while the seasonal is associated to allergens in special seasons of the year.
Hay fever affects 15 to 20 % of the population in Britain being a seasonal rhinitis triggered by pollens. Therefore, it is more frequent in the spring (march to may), when plants blossom. There are plants like perennial rye and timothy grass (very common in England) that release pollens in different seasons, in that case, symptom peak occurs during June and July.
Pollens are extremely lightweight and disperse trough the air and when inhaled it deposits in the mucous provoking inflammatory allergic reactions. The warm, sunny, dry, and windy days are the worst days for the allergic to pollen because pollen spores are more easily spread.
Hay fever is prevalent in North Hemisphere countries and it has been increasing over the past two decades. That is in part due to the high emission levels of nitrogen dioxide, and ozone from vehicles in the industrialized countries. Exposure to air pollution and pollen exacerbates the symptoms of hay fever.
Besides being uncomfortable rhinitis symptoms affect the quality of life of patients. Amid several symptoms the most common are:
Nose
Eyes
Chest
In order to minimize symptoms and allergic crisis, medicines are necessary. Some medicines are quite expensive and bring unpleasant side effects like making people sleepy and tired, and may also have a dangerous effect on driving and a poor concentration effect in school, at work and other activities.
In 1997, the Health System in the United States of America spent about USD 7.9 billions just with rhinitis.
Preventing allergic crisis is far better than taking medicines therefore allergic people should avoid whenever possible contact with pollens.
Mainly in spring time, some preventive measures should be taken:
On top of those measures, in order to control allergies, it is essential that
remaining pollen airborne particles be destroyed. Airfree silently and
efficiently incinerates airborne organic particles like pollens. Pollens are
essentially made of protein and because of that, when submitted to high
temperatures suffer a denaturizing process resulting in alteration of its
original form and consequently being destroyed.
