Be careful, if you are sensitive to pollen, you might have a pretty bad time for a few days. The National Aerobiological Monitoring Network has placed the Var and the Alpes-Maritimes on red alert for cypress pollen, in particular.
The entire Mediterranean region is affected by these pollens and the risk of allergy is high.. In addition to cypress pollens, hazelnut and alder pollens are also added. The network also indicates that parietaires and mimosas are also starting to bloom, but for the time being, the alert level is qualified as “low”. Note that there may be “so-called proximity allergies possible in sensitive people”.
The heat promotes pollination and the wind disperses the pollen grains in the air
Allergy is a hypersensitivity reaction initiated by a specific immune reaction to a foreign substance to the human body, called an allergen, of which pollens are a part. Three major pollen periods follow one another during the year.
First, that of tree pollen (olive, plane, birch, oak, etc.). Then that of grass pollen which corresponds to the period of hay fever. The season ends with grass and ambrosia pollens. The distribution of these pollens depends on weather conditions. The heat promotes pollination and the wind disperses the pollen grains in the air.
This year, the heat, which appeared early in the season, contributed to the dissemination of a very large quantity of pollen. According to the latest bulletin from the National Aerobiological Surveillance Network (RNSA), which monitors the content of biological particles in the air, almost all of France is on red alert for allergic risks.
In France, approximately 20% of children from the age of 9 and 30% of adults are now affected by pollen allergies, according to the Ministry of Health.
