First thunderstorms then sunshine, fungal spores and grasses fly through the air!

The second half of the week is dominated by thunderstorms and at the weekend the sun comes out again, with temperatures below 30° C. During thunderstorms, sudden changes in humidity and air pressure can cause pollen to split into tiny particles that penetrate deep into the lungs. This can trigger severe allergic reactions or asthma attacks - a phenomenon known as thunderstorm asthma. Even though rain usually brings short-term relief, allergy sufferers should stay indoors during thunderstorms and keep the windows closed to minimise the risk.

The mowing and rainfall have ensured that only moderate grass pollen concentrations are reached. Flowering grasses can also be found in forests and at altitudes above 1500 metres.

Dock and plantain also bloom and can cause additional pollution near meadows. Stinging nettles also bloom; their pollen can irritate sensitised people.

The peak bloom of privet and lime trees is over in Vorarlberg. From an allergological point of view, linden pollen is only of minor relevance, but its intense flower scent can cause irritation in sensitive people. People who are sensitised to the pollen of olive trees should avoid the immediate vicinity of privet bushes.

Moderate to high concentrations of fungal spores can be reached this week. Especially after precipitation, the exposure to fungal spores can increase in the short term.

Other types of pollen in the ambient air: umbellifers, goosefoot and buttercup plants as well as clove and cypress plants. These are of minor allergological importance.
