The risk of pollen allergy is maximum, warns the National Aerobiological Surveillance Network

The risk of grass allergy is highest across the country, according to the National Aerobiological Surveillance Network (RNSA). On the map of the risk of allergy to the body’s pollens, all the departments are in red (high risk of allergy), except two of them: Landes and Pyrénées-Atlantiques (medium risk).

On the social network Twitter, the RNSA warns: “While many French people will bridge the Ascension this week with traffic announced in black on the roads by smart bison, in terms of pollen, the grasses do not make the bridge and will remain present in the air! ”.

A situation that is likely to last

The RNSA is sounding the alarm on its site: the situation is likely to persist if the weather conditions remain unchanged.

Indeed, the sunny weather and the temperatures announced for the next few days are very favorable to the emission and dispersion of high concentrations of grass pollen in the air.

“From the beginning of May to the end of July, we should therefore find grass pollen present throughout France. Only rain showers can bring some respite to allergy sufferers by placing pollen on the ground, but they will also promote the growth of grasses which will release more pollen as soon as the sun returns!”, warns the body.
