Asthma attacks may occur unexpectedly and cause you to develop symptoms such as difficulty breathing, which can be life threatening without urgent medical treatment. The causes of asthma attacks differ for each person, and include exposure to indoor and outdoor environmental triggers, acute illnesses and chronic medical conditions that irritate or inflame your lungs. Consider a few important facts from the Mayo Clinic about what causes an asthma attack.
Allergens
Substances that trigger your allergies, such as pollen, dust, mold or pet dander, may also trigger an asthma attack.
Tobacco Smoke
Secondhand smoke from tobacco, or "third-hand" smoke, which is the residue left on chairs, clothes and fabrics can irritate your breathing passages and cause an asthma attack.
Air Pollution
Outdoor air pollution such as ozone and particulates from automotive exhaust can cause you to have an asthma attack, especially during hot summer weather.
Respiratory Infections
Respiratory infections such as the common cold, influenza and bronchitis may cause asthma attacks throughout the duration of the illness.
Chronic Sinusitis
Chronic sinus infections (sinusitis) may cause swelling and inflammation of your breathing passages, which can lead to asthma attacks.
Acid Reflux
Acid reflux that occurs frequently or is chronic can cause asthma attacks as a result of irritations to your throat and lungs.
Exercise
Strenuous exercise or physical activity may cause asthma attacks both during the activity as well as for a period of several hours after stopping the activity.
