The weather increases the emission and dispersion of pollen in the air, which increases the risk of allergies throughout France.
- The RNSA (National Aerobiological Surveillance Network) indicates that allergies are back almost everywhere in our territory.
- “Be careful, cypress pollens are very allergenic, particularly the common cypress-Provence cypress (Cupressus sempervirens),” the experts also warn.
- 25% of the French population suffers from respiratory allergies.
“The risk of allergies will soon be high in most French departments because of the spring weather which affects the entire territory.” On his site, the RNSA (National Aerobiological Surveillance Network) indicates that allergies are back almost everywhere in our territory.
With favorable winds, generous sunshine and remarkably mild temperatures sometimes exceeding 20°C between the Pyrenees, Languedoc and the Mediterranean rim, January heat records could soon be approached, or even exceeded. “These weather conditions will favor the emission and dispersion of pollen in the air,” explains the RNSA in an alert.
“The risk of allergy is already at the medium level and will increase quickly to reach the high level, persisting for several weeks,” adds the institution.
Risk of allergy: be careful cypress pollen!
The RNSA also informs allergy sufferers that cypress pollen (Cupressaceae family) is increasingly present in the air and could seriously bother them.
“Be careful, cypress pollens are very allergenic, particularly the best known and most feared by all allergy sufferers, namely the common cypress-Provence cypress (Cupressus sempervirens)”, experts warn. “They cause numerous ocular, nasal and even respiratory discomforts in allergy sufferers. Allergy sufferers must therefore follow the treatments prescribed by their doctor or consult them and limit their exposure to pollen,” they recommend.
Allergy risk:air pollution can modify sensitivity”
The RNSA also notes that air pollution in large cities can modify the sensitivity threshold of those allergic to pollen, thus exacerbating symptoms and particularly weakening the respiratory tract.
Mimosas, in flower in the South, can also cause local allergies.
25% of the French population suffers from respiratory allergies
Nearly 25% of the French population suffers from respiratory allergies. Many factors can be the cause of these manifestations:
– indoor environmental factors: these are all potential allergens breathed with the indoor air of the premises (mites, mold, cat hair, dog hair, etc.).
– External environmental factors: these include all potential allergens breathed with the outside air (pollens, mold).
– Air pollution factors.
According to the WHO, half of the world’s population is likely to be allergic by 2050.
