A rainy start to the week, but as soon as the weather improves, so too does the Polish load!

The weather forecast promises us precipitation for Monday and Tuesday. This will reduce the impact of the pollen count as it washes the pollen out of the air and prevents it from being released.

Birch trees are currently responsible for the main allergen in the ambient air. They still have the potential to release pollen and will do so as soon as the weather improves again. From Wednesday afternoon at the latest, allergy sufferers who are sensitised to birch will have to prepare themselves for high levels again.

In Vorarlberg, the hornbeam hornbeamswhich can increase the stress levels. Birch, alder, hazel and hornbeam can cause cross-reactions in people who are sensitised to birch plants.

While ash, willow and poplar are already fading in the valleys and only have small amounts of pollen left in the spectrum, they still have the potential to release pollen at higher altitudes. Allergy sufferers should avoid dense stands.

In parks and residential areas, individual plane trees have started to flower. These early starters are the first localised source of exposure for sensitised people.

In climatically favoured locations (sunny southern locations, green spaces in residential areas), flowering grasses and sour grasses have already been sighted. In their surroundings, sensitised allergy sufferers may experience initial symptoms.

In addition to the pollen types already mentioned maple oaks, larches and cypress plants are also represented in the pollen spectrum. However, they only have a very low potential for allergic reactions.
