Pollen allergies affect people in Nîmes, France. Pollen comes from trees, grasses, and weeds. It's in the air and can cause symptoms.
Trees start releasing pollen in February. Hazelnut, alder, and birch trees are first. Oak and pine trees follow in March. Pollen counts are highest in the morning.
Grasses start releasing pollen in May. This pollen is very allergenic. Symptoms peak in June when grasses are in full bloom.
Weeds like ragweed release pollen in July. This pollen is also allergenic. Pollen counts decrease in August when temperatures rise.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
