Also known as allergic rhinitis, hay fever is an all-too-common allergic condition that affects 19.2 million people in the United States alone, based on the results of the 2018 National Health Interview Survey.

What are the symptoms of hay fever?

Hay fever happens due to an allergic reaction in response to various kinds of allergens. These allergens include dust, pollen, tiny bits of animal fur and skin, and the like. It usually lasts for as long as the person is exposed to the sources of these allergens.
