Season 2017:


There is almost no tree pollen present in the air and the grass pollen season is also at its end.

During the summer months, the air contains high densities of allergenic fungal spores from the genera Alternaria and Cladosporium. These molds typically grow on decaying herbaceous plants.


Good to know:

  • Indiviual sensitivity may vary a lot. It is reported in literature that from 50 grass pollen grains per m³, most sufferers sensitized to this type of pollen will experience allergy symptoms. For Alternaria and Cladosporium, 500 and 3000 spores per m³ are respectively enough to induce respiratory problems for sensitized persons.


Several useful recommendations for allergic people:

  • Rigorously follow the treatment prescribed by your physician.
  • Avoid outdoor efforts and activities (sports, physical efforts). Indoor activities are a better option.
  • Limit the aeration of your home during the pollen season, preferably during or after the rain. Keep the windows closed when you travel by car.
