Asthma Triggers that Cause Asthma attack

Asthma Triggers comprise of :

Allergens Infections to Respiratory and Sinusitis
Pollen
Mold
Animal protein (dander, urine, oil from skin)
House dust/dust mites
Irritation of the airways, nose, throat, lungs, and sinuses, and may lead to  asthma triggers.
Irritants Medications Sensitivity
Strong odors and sprays, such as scents, household cleaners, cooking gases, paints, and varnishes.
Chemicals such as coal, chalk dust, or talcum powder.
Tobacco smoke, wood smoke, chemicals in the air, and ozone.
Weather condition changes, including temperature changes, barometric pressure, humidity, and strong winds.
On the job chemical exposure, such as occupational vapors, dust, gases, or fumes.
Medications, such as aspirin and additives such as sulfites, cause up to 20 percent of adult asthmatic attacks as a consequence of sensitivities or allergies to them. These medications often include:
Aspirin
Other non-steroidal anti-inflammatory medications, such as ibuprofen, indomethacin, naproxen
Sulfites used as food and beverage preservatives.
Beforehand any medication taking, including over-the-counter medications, converse with your doctor.
Exercise Gastroesophageal Reflux
Tireless physical exercise can trigger an asthma attack, often because of the inhaled cool and dry air. Long-term vigorous activities such as long distance running are most likely to bring asthma, and swimming is the least probable. GERD, or indigestion, a condition characterized by persistent reflux of stomach acids, is common in individuals with asthma. Symptoms may consist of heartburn, burping, or spitting up in infants.
Smoke Emotional Unease and Nervous Strain
Whether directly or passively inhaled, Tobacco smoke has been shown to have detrimental effects on the airways. Stress and anxiety reactions are considered to be more of an outcome than a reason. They can cause fatigue, which may affect the immune system and, in turn, raise either asthma symptoms or bring on an attack.
