siitepölykausi

Siitepölykausi, often translated as pollen season, refers to the period of the year when plants release pollen, a fine powder that is essential for plant reproduction. In many regions, this season is closely associated with spring and summer, although the exact timing and duration vary significantly depending on the local climate, plant species, and geographical location. Different types of plants release pollen at different times. For example, trees often release their pollen early in the spring, followed by grasses in late spring and summer, and finally weeds in late summer and autumn.

The release of pollen can have a significant impact on human health, particularly for individuals who suffer from pollen allergies, commonly known as hay fever or allergic rhinitis. When airborne pollen comes into contact with the mucous membranes of the eyes, nose, and throat, it can trigger an immune response, leading to symptoms such as sneezing, itchy eyes, runny nose, and nasal congestion. The concentration of pollen in the air, or pollen count, is often monitored and reported in weather forecasts, allowing allergy sufferers to take precautions. These precautions can include staying indoors during peak pollen times, keeping windows closed, and using air purifiers. Environmental factors like wind and humidity also play a role in pollen dispersal and concentration.
