Seasonal allergies — also called hay fever or seasonal allergic rhinitis — affect millions of Americans every year with discomforts such as a runny nose, nasal congestion, sneezing, and eyes that are watery or itchy. These symptoms can make it hard to breathe, get adequate sleep and focus on work — and they can make you more vulnerable to sinus infections or worsen underlying asthma.
You develop allergies because your immune system perceives something that is typically harmless — such as pollen — as harmful. This causes the immune system to generate immunoglobulin E (IgE) antibodies that remain on the alert for that particular substance. The next time you breathe in pollen, these antibodies signal your immune system to release chemicals such as histamine, which lead to the signs and symptoms of allergies.
Tree pollen is most common in the early spring, grass pollen is prevalent in the late spring and summer, and ragweed pollen explodes during the fall. However, the lengths of the pollen seasons in North America can vary depending on the climate you live in.
