The arrival of spring temperatures rhymes with pollens and allergies. According to the National Aerobiological Surveillance Network, birch pollen has spread over the northern half of France this week.
The RNSA specifies that the birch releases its pollen from the end of March to the end of April. The report also claims that concentrations are “particularly strong on bright sunny days.” Something to warn people with allergies.
The RNSA has also issued a press release on twitter to warn of the arrival of birch pollen this week:

Indeed, this species of tree belongs to the Betulaceae family, a very allergenic variety that is very present in cities. These trees are recognizable by their white, shiny trunks and can cause severe itchy eyes, nose and even respiratory symptoms with asthma attacks.
precautions to take
In order to limit the risk of allergies, the RNSA advise allergy sufferers to take several precautions, such as rinsing their hair at the end of the day, opening the windows before and after sunset and not drying their clothes outside during the period in question. .
It is also recommended to wash your nose once a day with sea water or consult a doctor for a prescription of antihistamines.
