Irritants found in ambient air can cause problems for some, while others are seemingly unaffected. Rhinitis, sinusitis, and asthma can result from irritant reactions as well as allergic ones. Often accompanied by watery and red eyes. Rhinitis is usually caused by an allergic, irritant, or infectious process. The nose and nasal cavity is the entry point for air into the body.
Air is moisturized, warmed, and filtered as it moves through the passages.
Allergic Rhinitis Allergies that effect the nasal passages are common. It is difficult for those that do not suffer to understand that these allergies cause much more than a runny nose and sneezing. While these allergies are generally not life threatening, they do effect quality of life and can lead to more serious problems. While over two thirds of those having allergic episodes continue to function in their jobs and daily lives, they do not feel well and often curtail activities because of their allergies. Allergic rhinitis is treated by environmental controls to reduce exposure to allergens and medication.
