The Swiss Tropical and Public Health Institute (Swiss TPH) in collaboration with the Federal Office of Meteorology and Climatology (MeteoSwiss) has found that rising temperatures over the last 30 years has had a considerable influence on the onset, duration and intensity of the pollen season.
'For at least four allergenic species, the tree pollen season now starts earlier than 30 years ago – sometimes even before January,' said Marloes Eeftens, Principal Investigator and Group Leader at Swiss TPH. The duration and intensity of the season have also increased for several species meaning that people with allergies suffer longer and react stronger to higher concentrations.
On top of this, pollen allergies are becoming more and more widespread. Today, 20% of the Swiss population suffers from hay fever, compared to only 1% 100 years ago, said Swiss TPH. The study suggests this could be because of environmental changes such as urbanisation and hygiene habits.
