Tree pollen is a fine powder produced by trees during their reproductive cycle. It contains male gametes that are essential for fertilizing female flowers. Different types of trees, such as oak, pine, and maple, release pollen at various times of the year, often in spring. When tree pollen is released into the air, it can travel long distances, leading to potential allergic reactions in some people. Symptoms of pollen allergies may include sneezing, runny nose, and itchy eyes. Understanding tree pollen can help individuals manage their allergies and enjoy the outdoors more comfortably.
