According to the National Institute for Allergy and Infectious Diseases, the American Academy of Allergy, Asthma, and Immunology, and other organizations, triggers for asthma include:
||Respiratory Infections and Sinusitis
- animal protein (dander, urine, oil from skin)
- house dust/dust mites
- certain foods
|Infections can cause irritation of the airways, nose, throat, lungs, and sinuses, and worsens asthma.
||Sensitivity to Medications
- strong odors and sprays, such as perfumes, household cleaners, cooking fumes, paints, and varnishes
- chemicals such as coal, chalk dust, or talcum powder
- air pollutants
- changing weather conditions, including changes in temperature, barometric pressure, humidity, and strong winds
- chemical-exposure on the job, such as occupational vapors, dust, gases, or fumes
|Medications, such as aspirin and sulfites, may cause asthmatic attacks as a result of sensitivities or allergies to them. These medications often include:
- other non-steroidal anti-inflammatory medications, such as ibuprofen, indomethacin, naproxen
- sulfites used as preservatives in food and beverage
Before giving your child any medication, including over-the-counter medications, talk with your child's physician.
|Exercise can trigger an asthma attack, often because of the inhaled cool and dry air. Long-term strenuous activities such as long distance running, are most likely to induce asthma, and swimming is the least likely.
||GERD, a condition characterized by persistent reflux of stomach acids, is common in individuals with asthma. Symptoms may include heartburn, belching, or spitting up in infants.
||Emotional Anxiety and Nervous Stress
|Tobacco smoke, whether directly or passively inhaled, has been shown to worsen asthma.
Wood smoke from wood-burning heating stoves and fireplaces can release irritating chemicals such as sulfur dioxide.
|Reactions from stress and anxiety are considered to be more of an effect than a cause. They can cause fatigue, which may affect the immune system and, in turn, increase either asthma symptoms or bring on an attack.
