Pollens are gaining ground.
According to a map from the National Aerobiological Surveillance Network (RNSA), 31 departments are placed in “
high
” health impact for pollen.
Mainly from the departments of southern and eastern France, such as Bouches-du-Rhône, Pyrénées-Orientales and Bas-Rhin.
All of the other departments in France have a “
medium
” health impact.
Main reason according to the RNSA, the "
spring
" weather this week.
Different types of pollen are involved.
For example, in the Bas-Rhin, it is birch, hornbeam or ash pollen, only hornbeam in Haute-Saône, etc.
"In the south of the country, cupressaceae pollen
(from trees such as juniper or cypress, editor's note)
remains very present in the air and will bother allergy sufferers with moderate concentrations and a high level risk of allergy"
, indicates the RNSA on its site.
A lull to be expected
In
“much of the country”
this time, birch pollen “
will bother allergy sufferers with a medium to high level allergy risk
”
.
"Hornbeam pollens which are from the same family as birches are also present in the air at the end of March with a risk of allergy which will evolve between the low level and the high level according to the departments", completes the
RNSA .

The sunny weather on Wednesday and Thursday favored the appearance of birch pollen.
Nevertheless, the RNSA reassures: “
the concentrations will drop in the coming days under the rain showers which will bring some respite to those with allergies
”
.
According to the various models, the lull could occur as early as this Friday, March 31.
At the same time, “
plane tree pollen begins to flower with a low to medium risk of allergy
”
.
"
Be careful especially with micro-needles [...] which are very irritating and can cause coughing
"
,
still warns the RNSA on Twitter.
