If you have asthma, summer can be a difficult season. Heat and humidity can affect your airways and trigger wheezing, shortness of breath, and other symptoms, increasing the likelihood of asthma attacks. This is regardless of the type of asthma you have, but if you happen to have allergic asthma, you may find managing your asthma to be especially challenging, as allergens such as pollen and mold are particularly plentiful in hot, humid weather. The same is true if you have exercise-induced asthma and tend to be more active outdoors during the summer.
