Precipitation provides short-term relief!

After a spring-like first half of the week, a cold front will bring cooling and precipitation in the coming days, providing relief for allergy sufferers. However, as soon as the sun is able to assert itself again, a rapid increase in exposure is to be expected.

The main reasons for this, in addition to the ash trees that are currently in full bloom, are ash trees also the birches. Many plants are about to be ready to flower or are already releasing pollen. Low to moderate pollen concentrations have been recorded over the past few days. The change in the weather will stop the release of pollen in the short term, but it will quickly pick up again with the next improvement in the weather.

The hornbeam has already reached flowering stage in a number of Viennese parks and can cause additional stress for people who are sensitised to birch pollen due to cross-reactions.

In addition to the pollen types mentioned above, maple, yew, poplar and cypress plants are also represented in the pollen spectrum. However, they only have a very low allergenic potential.
