There are three species of ragweed monitored in France: ragweed with leaves of sagebrush (Ambrosia artemisiifolia), ragweed trifid (Ambrosia trifida) and ragweed with smooth ears (Ambrosia psilostachya), according to Ambrosia observatory. These plants, native to North America, grow quickly and are therefore very allergenic.
Heat waves might increase the concentration of ragweed pollen
The coming weeks might be particularly difficult for sensitive people. For now, the risk of allergy to pollen ranges from low to medium in France, according to the National Aerobiological Surveillance Network (RNSA). But the upcoming heat waves might favor the concentration of ragweed pollen.
THE allergic reactions to this pollen are multiple : rhinitis, conjunctivitis, tracheitis, asthma, urticaria. In 2017, more than 660,000 people were affected by ragweed allergies in Auvergne Rhône Alpes. This is the French region most invaded by ragweed.
Tips to limit allergies
To limit the risk of allergies, the Ile-de-France Regional Health Agency (ARS) recommends rinsing your hair in the evening, ventilating your home for at least ten minutes a day, avoiding other irritating factors (tobacco, home fragrances, etc.), avoiding outdoor activities that lead to overexposure to pollen, not to dry clothes outside and to keep car windows closed when driving so that pollen does not enter.
In France, the authorities recommend that individuals remove ambrosia if they have it on their property. In the public space, you can also remove them yourself or report them on this platform.
