According to the MeteoNews platform, those who suffer from pollen allergy in Switzerland have had a tough year.
Due to the very mild winter, hazels and alders began to bloom in the first half of January already - much earlier than usual.
Then, due to the hot and dry summer, grass pollen concentrations were then above average from May to July.
According to MeteoNews, global warming and increased dry spells put the plants under stress. Plants reacted to this stress with increased pollen production.
