According to the latest weekly bulletin from the national agency responsible for surveying pollen levels that trigger allergies (RNSA), most of the country will be on “red alert”, meaning levels are “very high”.
The high temperatures and sun predicted for the week ahead are partly responsible for the increased levels of pollen from grass in the air.
Around 10-20 percent of the French population suffer from allergic reactions to pollen.
The network recommends that allergy sufferers make it a priority to take their medication or consult one of the RNSA's doctors.

The grass carrying this kind of pollen is found in all kinds of landscapes likes meadows, rocky areas, forests, as well as in water, ditches and on the side of roads.
Grass pollen generally reaches its peak in the month of June.
