For people who suffer from asthma, an attack can occur when they are exposed to environmental triggers. These triggers can vary from individual to individual, but there are a number of common asthma triggers that impact many people.

By understanding what can trigger an asthma attack, those who suffer from the condition can take steps to avoid them or prepare themselves in those cases when they cannot be avoided. Common asthma triggers include:

• Mold - Breathing in mold can trigger an asthma attack. Homes and buildings with high humidity levels or that have suffered from water damage may contain high levels of mold.

• Dust Mites - Dust mites are tiny bugs that are found in most homes. To prevent an asthma attack, use mattress and pillowcase covers to make a barrier between dust mites and yourself and wash bedding on the hottest water setting.

• Cockroaches - Cockroaches and their droppings can trigger an asthma attack. Get rid of cockroaches in homes by removing as many water and food sources as possible.

• Pets - Furry pets can trigger an asthma attack. Keep pets out of bedrooms, bathe pets each week when possible and vacuum regularly.

• Smoke - Smoke from burning wood or other plants is made up of a mix of gases and small particles. Breathing in too much can cause an asthma attack.

• Outdoor Pollution - Outdoor air pollution from factories, cars and other sources can also trigger an asthma attack.

• Other Triggers - Infections linked to influenza, colds and respiratory viruses can trigger an asthma attack. Sinus infections, allergies, breathing in certain chemicals, and acid reflux are also potential triggers. Even physical exercise; some medicines; bad weather; breathing in cold, dry air; and some foods, food additives, and fragrances can act as an asthma trigger.
