Do changes in weather affect asthma?
Asthma can be affected by numerous factors, and the weather is often cited as an example. It is generally recognized that cold dry air can induce bronchoconstriction in susceptible individuals. Probably of greater importance than the atmosphere itself, however, is the burden of allergens that themselves vary with the weather. For example, mold and pollen counts have typical seasonal patterns, and it is well-recognized that exposure to such allergens can induce asthmatic attacks in sensitized (allergic) individuals. Also, viral infections are a common precipitating factor for asthma attacks, and viruses that cause flu and the common cold, for instance, typically occur in certain seasons. So, the short answer to your question is, yes changes in the weather can affect asthma, but it probably occurs via a number of related mechanisms.
