One of the most common triggers of allergic reactions in spring is pollen. During the springtime, many plants release pollen into the air as part of their reproductive process. This pollen can be carried by the wind and is a major allergen for a significant portion of the population. Common sources of springtime pollen allergies include trees such as oak, birch, maple, pine, and cedar. The release of pollen during the spring season can lead to allergic reactions in individuals who are sensitive or allergic to these specific types of pollen. Symptoms of pollen allergies, also known as hay fever or seasonal allergic rhinitis, may include sneezing, runny or stuffy nose, itchy or watery eyes, and throat irritation.
