September is full of transitions. The season shifts from summer into fall, the lazy days of summer vacation are replaced by the structure of the school week, and dinner menus change from smoky outdoor grilling to cozy simmering soups. September brings another shift, too, for those suffering from asthma—a dramatic increase in exposure to triggers that culminate in Asthma Peak Week.
For the more than 27 million children and adults in the United States who live with asthma, the third week of September, (or more precisely, the 38th week of the year, which in 2023 runs from September 18 to 24) represents a potential health hazard. Named “Asthma Peak Week” by experts and organizations in the northern hemisphere, the week seems to be a perfect storm of circumstances that converge into a significant health threat.
