Allergic Rhinitis
Allergic rhinitis affects more than 1.4 billion people worldwide and is the condition where the immune system recognizes an intruder which in this case is called an allergen. The immune system responds to the allergen by releasing histamine and chemical mediators, and these typically cause symptoms in the nose, throat, eyes, ears, skin and roof of the mouth. Pollen in the air causes seasonal allergic rhinitis (hay fever) which happens in different parts of the country during different times of the year.

Nasal blockage is the most common symptom in allergic rhinitis as well as problems sleeping, snoring, dry throat, morning headache, mouth breathing, sleep apnea, and sleeping during work or school due to a restless night of sleep. Children with nasal blockage will typically have more of these symptoms. In a study conducted in Thammasat University Hospital it was found that in children with allergic rhinitis there is a higher prevalence of sleep problems that in those without allergic rhinitis.
Allergic rhinitis (allergies) may occur year-round or seasonally. When it occurs seasonally it is usually caused by airborne particles from trees, grass, ragweed, or outdoor mold.
