Causes Of Allergic Rhinitis

Allergen is something that triggers the allergy. When a person is allergic rhinitis, inhaled allergens such as pollen or dust, the body releases chemicals such as histamine. This causes allergy symptoms such as itching, swelling, and mucus production.

Hay fever involves an allergic reaction to pollen. (A similar reaction occurs with allergy to mold, animal dander, dust and similar inhaled allergens).

The pollens that cause hay fever vary from person to person and from region to region. Small, hard to see pollens often cause hay fever. Examples of plants commonly responsible for hay fever include:

Trees (deciduous and evergreen)

Herbs

Ragweed

The amount of pollen in the air can play a role in whether hay fever symptoms develop. Hot, dry and windy weather are more likely to have increased amounts of pollen in the air cool and damp, rainy days when most pollen is washed to the ground.

Some disorders may be associated with allergies. These include eczema and asthma.

Allergies are common. Your genes and environment can make you more susceptible to allergies.

Or are you more likely to develop allergies is often transported to the families. If both parents have allergies, you probably suffer from allergies. The opportunity is greater if the mother has allergies.
