I personally believe that asthma and weather go hand in hand, though, of course, there are so many other asthma triggers such as pollens, chemical substances, roach droppings and animal dander etc.
Humid weather always affects my asthma, probably because it promotes mold growth.
On the other hand, some people say dry air triggers asthma attacks, probably due to dead mites. Some people like humidifier but others dehumidifier.
Also, some reports say that air pressure could affect asthma.
When your asthma worsens?
