Pollen allergies affect many people in Caen, France. It occurs when the body's immune system reacts to pollen from trees, grasses, and weeds.
In Caen, pollen seasons start in March with tree pollen. Hazelnut, birch, and oak trees release pollen into the air. This lasts until May.
From May to July, grasses release their pollen. This is the most intense pollen season. People with allergies may experience symptoms like sneezing, itching, and runny eyes.
August to October is the weed pollen season. Ragweed, nettle, and sorrel are common allergenic weeds. During this time, people with pollen allergies should stay indoors and keep windows closed.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
