A diagnosis of allergic rhinitis is connected to a set of symptoms that affect the nose. These signs appear when you breathe in an allergen, such as pollen, dust, or animal dander. When you consume a food to which you are allergic, symptoms may also appear.

Something that causes an allergy is known as an allergen. The body releases chemicals that induce allergy symptoms when a person with allergic rhinitis breathes in an allergen such pollen, mould, animal dander, or dust.

Several allergens, such as the following, can cause seasonal and year-round allergies:

• Dust mites that reside in furniture, bedding, draperies, and carpets.
• Tree, grass, and weed pollen.
• Pet hair (tiny flakes of dead skin).
• Spores of mould.
• Cockroaches, along with their excrement and saliva.

Whether or not hay fever symptoms appear can depend on the amount of pollen in the air.

• Pollen levels in the air are more likely to be high on hot, dry, windy days.
• The majority of pollen is washed to the ground on cool, wet, rainy days.

Many allergy drugs can reduce symptoms and make living with hay fever easier. These medications can be taken as liquids, pills, eye drops, nasal sprays, or injections, among other delivery methods. Before taking any drug, especially if you're pregnant or have other health issues, consult your doctor. Hay fever cannot be prevented, but you can manage your allergies with a change in your way of life. By minimising your exposure to irritants, you can reduce the symptoms of hay fever.
