Histamine is a natural chemical that protects your body against allergens. Allergy rhinitis can be caused by this chemical. Symptoms include a runny nose and itchy eyes.
Other common allergens than tree pollen include:
- Grass pollen
- dust mites
- Animal dander is old skin.
- Cat saliva
Pollen can cause problems at certain times of the year. The spring is when pollen from trees and flowers is most common. In the summer and autumn, weeds and grasses produce more pollen.
There are two types of allergic rhinitis: seasonal and permanent. Seasonal allergies are most common in the spring and autumn seasons and usually arise due to exposure to pollen and other allergens. Perennial allergies may occur all year, or any time of the year, as a result of indoor allergens like dust mites, pet dander, and other substances.
Although allergies can affect anyone, you are more likely to get allergic rhinitis from someone with a history of allergy. Atopic eczema or asthma can increase your chances of developing allergic rhinitis.
This condition can be triggered by external factors, such as:
- cigarette smoke
- Cold temperatures
- air pollution
- wood smoke
