Mieux respirer pour mieux étudier

Les scores cognitifs des enfants étudiant dans des lieux correctement ventilés seraient supérieurs de 61% aux autres (1). Placée sous les feux de l’actualité par les modes de contamination du virus en aérosol, la qualité de l’air « indoor », apparait – au delà de la crise sanitaire- dans toute son importance. Alors que bon nombre de personnes passent l’essentiel de leur existence indoor, la réflexion sur qualité de l’air ne semble pourtant pas être à la hauteur des enjeux publics, tant pour la santé que le développement des capacités cognitives des enfants.

Researchers have linked poorly ventilated spaces to a range of ailments—headaches, fatigue, shortness of breath, cough, sneezing, eye-, nose-, throat- and skin irritation, dizziness, and nausea—that are sometimes given the name “Sick Building Syndrome”. Poor ventilation has also been linked to increased absence from work, decreased productivity and asthma. Schools in particular are “chronically under ventilated”, according to a recent report by the Lancet covid-19 commission. In America, nearly one child in 13 has asthma—a condition triggered by allergens commonly found in schools. It is a leading cause of absence from school. Components of outdoor air pollution can penetrate inside buildings, and childhood exposure to these pollutants can impact neurodevelopment and academic performance. It can also lead to childhood cancer. Children exposed to high levels of air pollution may also be at greater risk of cardiovascular disease later in life. Improved ventilation has been linked with better academic performance. Maths and reading scores go up, and pupils are measurably more attentive in class. Even office-workers benefit from better indoor air. One study found the cognitive scores of people in well-ventilated offices were 61% higher than those of workers in conventional office set-ups » rapporte la revue The Economist (2).
