A variety of pollens are coming! Residents in many parts of France are at moderate risk of allergies

Recently, a variety of pollens have filled the air. The concentration of pollen in the air will gradually increase in the coming weeks. Wearing a mask is a good way to avoid pollen allergies.

According to Le Parisien, large amounts of birch pollen will appear in Paris, Lyon, and central France. According to the information released by the French Meteorological Service and the French Network for the Detection of Air Biology (RNSA), birch pollen will gradually spread across northern and western France from April 5. According to RNSA, residents of Auvergne Rhône-Alpes, Ile-de-France and western France are at moderate risk of allergies.

Charlotte Sindt, head of the French air biodetection network, said birch pollen is mainly scattered in northern France, with small amounts scattered in the woods in the south. Birch pollen is a pollen that is highly allergenic. In the absence of rain and cooling, birch pollen will be present in large quantities in the next three to four weeks.

By observing the growth cycle of birch trees, it was found that the pollen will be present in large quantities, but will not cause severe allergic reactions. In the Mediterranean region, residents will be at moderate risk of allergy to birch pollen.

At the same time, residents will have a low risk of oak pollen allergy, but in April and May, residents will gradually face increasingly severe oak pollen allergy symptoms. Meanwhile, residents should also be alert to grasses, the herbaceous plants that grow along roadways. Their pollen will appear in large quantities in April, and in May and June, the pollen concentration will be very high. Isabelle Bossé, an allergist in La Rochelle, Charente-Maritime, said that most allergies are caused by pollen from grasses.

Charlotte Sinter warned that allergy symptoms are mainly itchy throat, nose and eyes, repeated sneezing and watery eyes. Sometimes, allergy sufferers will have nasal congestion, asthma and cough symptoms. In addition, allergy sufferers may experience fatigue and sleep problems.

As with the new coronavirus, there are some precautions residents can take to prevent pollen allergies. 11:00 to 17:00, when the concentration of pollen in the air is high. During this period, residents should not open windows for ventilation. Allergy-prone people need to change their clothes when they go home and wash their hair before going to bed. In addition, residents should avoid drying clothes outdoors, avoid going out or doing sports outdoors in full sunlight or when it is windy, and keep car windows closed.

Wearing a mask can also stop pollen from entering the nasal passages, according to Isabelle Posse and Charlotte Hinter. During the new crown epidemic, masks can prevent pollen from attacking the face. In some Asian countries, many residents already avoid allergy symptoms by wearing masks.
