Pollen allergies occur when the body reacts to pollen from trees, grasses, and weeds. Symptoms include itchy eyes, runny nose, sneezing, and congestion.
Sundbyberg, Sweden has three pollen seasons: tree, grass, and weed. Tree pollen season starts in late March and ends in early May. Birch is the most common allergenic tree.
Grass pollen season begins in mid-May and lasts until early July. This is the most intense pollen season in Sundbyberg. Grasses like timothy and orchard release large amounts of pollen.
Weed pollen season starts in late July and ends in early September. Weeds like nettle and sorrel produce allergenic pollen. Pollen counts are usually lower during this season.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
