The next few days are likely to be complicated for people suffering from seasonal allergies: a “cocktail” of desert particles, ozone and pollen will fly over the south-east of France until Thursday, increasing the risk of crisis and respiratory discomfort.
- A “cocktail” of desert particles, ozone and pollen is likely to create difficulties for people suffering from seasonal allergies this week.
- A cloud of dust from the Sahara will cross the south-east of France until June 22.
- The RNSA adds that the risk of grass pollen allergies remains at a medium to high level in France.
Grasses, lime trees… several pollens are present in the French sky, but the real difficulty for people with allergies risks becoming the Sahara. Desert sand will cross the south-east of France this week.
Respiratory disorders: the sand of the Sahara crosses the South-East of France
The National Aerobiological Surveillance Network (RNSA) warns in the update of its allergy risk map of France of June 20, 2023. “A episode of desert dust is announced in several regions from June 20. The “cocktail” of desert particles, ozone and pollen therefore requires the greatest vigilance, especially among allergy sufferers”.
According to the website Weather Expressthe regions mediterranean will be the first to be affected by this sand from the Sahara. Corsica will record the highest dust concentrations. “THE Tuesday June 20 and Wednesday June 21, the sand will fly over all regions of the southeastern quarter. The concentrations are expected to be significant and sufficient to give a particular tint to the sky (milky or even ocher aspect). This dust may temporarily overflow from the Pyrenees to Alsace, while the north and west will not be affected. They will start to decline from Thursday June 22 before the end of the episode on Friday.warns the body.
If this desert dust penetrates the body less easily than fine particles because of their larger size, they can cause respiratory discomfort or amplify existing disorders. (asthma, seasonal allergy) if the rate is important. Respiratory problems are all the more important if the sand is coupled with other problematic elements such as ozone and pollen, as is the case this week. Fragile people must therefore be cautious until the end of the week.
Pollen allergy: the ever-present grasses and lime trees
In addition, the hot and sunny weather continues to benefit grass pollen. They thus remain present throughout France. The risk of allergy is classified as medium to high by the RNSA, depending on the departments. “The many storms that will cross the country in the coming days will be accompanied by heavy rain showers that will give allergy sufferers some respite by dropping pollen on the ground. Pollen concentrations in the air will normally drop at the end of the week”says the organization.
In addition, the lime trees are in bloom. Proximity allergies will thus be possible for people suffering from seasonal rhinitis. On the other hand, the pollens of oak, chestnut, olive, plantain, sorrel and nettles (urticaceae) should leave them alone. The risks of allergy are low.
