Your asthma may improve
Got wheezing? It’ll most likely get better for a day or two around ovulation, according to a 2012 Norwegian study. When researchers charted symptoms of nearly 4,000 women over the course of their menstrual cycles, they found that while wheezing and shortness of breath were higher during the middle two weeks of the month (when estrogen levels are naturally high), both symptoms dipped right around the time of ovulation (days 14 to 16). “We see this anecdotally, too, so it makes sense that a woman should talk to her allergist about individualizing her asthma treatments to her menstrual cycle,” says Bryan Martin, DO, president of the American College of Allergy, Asthma, and Immunology.
