Things that cause asthma episodes are called triggers. Indoor asthma triggers may be found at home, at school, or at work.
Common Indoor Asthma Triggers
Asthma can be triggered by smoke from the burning end of a cigarette, cigar, or pipe. Asthma can also be triggered by the smoke breathed out by a smoker.
Dust mites are tiny bugs you can't see. Dust mites live in bed sheets, blankets, pillows, mattresses, soft furniture, carpets, and stuffed toys.
Mold & Mildew
Mold and mildew grow on damp surfaces such as shower curtains, bath toys, tubs, basins, and tiles. Leaky plumbing and roof leaks cause dampness, which can cause mold to grow in your home.
Cockroach droppings and body parts may trigger asthma episodes.
The skin flakes and saliva of furry pets like cats and dogs can trigger asthma.
