| How does pollen trigger allergy symptoms or hay fever? | |
|
People with "hay fever" react to one or more specific allergens such as pollen or mold. A number of weed, tree, or grass pollens can cause "hay fever", depending on your specific allergies. Pollen in the air is inhaled and pollen grains land on the lining of the nose or bronchial tubes in the lungs. This does not cause a problem for most people.
In allergic individuals,
The inflamed linings of your nose, sinuses, and eyes result in runny nose, irritated throat, nasal congestion, sneezing, and watery eyes. Symptoms often intensify several times a day during pollen season. Symptoms can disturb sleep and trigger asthma, headaches, recurrent sinusitis, recurrent sore throats, fatigue and irritability. |
