Pollen allergies happen when trees, grasses, and weeds release tiny particles into the air. These particles cause allergic reactions in some people.
In Davos Wiesen, Switzerland, pollen seasons start in March and end in October. Tree pollen is highest in March and April. Grass pollen is highest in May and June.
Weed pollen is highest in July and August. Some days have higher pollen counts than others. Weather can affect pollen counts. Wind, rain, and temperature influence pollen release.
Pollen counts are usually highest in the morning and evening. People with pollen allergies should stay indoors during these times. Keeping windows closed helps reduce pollen exposure.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
