Pollen allergies affect many people in Les Sables-d'Olonne, France. They cause symptoms like sneezing, congestion, and itchy eyes. Grasses, trees, and weeds release pollen into the air.
Trees release pollen in early spring, from February to April. Oak, birch, and hazelnut trees are common allergenic species in Les Sables-d'Olonne. Pollen counts are highest in the morning.
Grasses release pollen in late spring and early summer, from May to July. Ryegrass, timothy, and orchard grass are common allergenic species. High temperatures and humidity make pollen counts worse.
Weeds release pollen in late summer and early fall, from August to October. Ragweed, nettle, and sorrel are common allergenic species. Pollen counts are usually lower in the afternoon.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
